If you want to use SELinux, chances are you will want
|
||||||
|
to use the distro-provided policies, or install the
|
||||||
|
latest reference policy release from
|
||||||
|
http://oss.tresys.com/projects/refpolicy
|
||||||
|
|
||||||
|
However, if you want to install a dummy policy for
|
||||||
|
testing, you can do using 'mdp' provided under
|
||||||
|
scripts/selinux. Note that this requires the selinux
|
||||||
|
userspace to be installed - in particular you will
|
||||||
|
need checkpolicy to compile a kernel, and setfiles and
|
||||||
|
fixfiles to label the filesystem.
|
||||||
|
|
||||||
|
1. Compile the kernel with selinux enabled.
|
||||||
|
2. Type 'make' to compile mdp.
|
||||||
|
3. Make sure that you are not running with
|
||||||
|
SELinux enabled and a real policy. If
|
||||||
|
you are, reboot with selinux disabled
|
||||||
|
before continuing.
|
||||||
|
4. Run install_policy.sh:
|
||||||
|
cd scripts/selinux
|
||||||
|
sh install_policy.sh
|
||||||
|
|
||||||
|
Step 4 will create a new dummy policy valid for your
|
||||||
|
kernel, with a single selinux user, role, and type.
|
||||||
|
It will compile the policy, will set your SELINUXTYPE to
|
||||||
|
dummy in /etc/selinux/config, install the compiled policy
|
||||||
|
as 'dummy', and relabel your filesystem.

A Simple Guide to Configure KGDB
|
|
||||||
|
|
||||||
Sonic Zhang <sonic.zhang@analog.com>
|
|
||||||
Aug. 24th 2006
|
|
||||||
|
|
||||||
|
|
||||||
This KGDB patch enables the kernel developer to do source level debugging on
|
|
||||||
the kernel for the Blackfin architecture. The debugging works over either the
|
|
||||||
ethernet interface or one of the uarts. Both software breakpoints and
|
|
||||||
hardware breakpoints are supported in this version.
|
|
||||||
http://docs.blackfin.uclinux.org/doku.php?id=kgdb
|
|
||||||
|
|
||||||
|
|
||||||
2 known issues:
|
|
||||||
1. This bug:
|
|
||||||
http://blackfin.uclinux.org/tracker/index.php?func=detail&aid=544&group_id=18&atid=145
|
|
||||||
The GDB client for Blackfin uClinux causes incorrect values of local
|
|
||||||
variables to be displayed when the user breaks the running of kernel in GDB.
|
|
||||||
2. Because of a hardware bug in Blackfin 533 v1.0.3:
|
|
||||||
05000067 - Watchpoints (Hardware Breakpoints) are not supported
|
|
||||||
Hardware breakpoints cannot be set properly.
|
|
||||||
|
|
||||||
|
|
||||||
Debug over Ethernet:
|
|
||||||
|
|
||||||
1. Compile and install the cross platform version of gdb for blackfin, which
|
|
||||||
can be found at $(BINROOT)/bfin-elf-gdb.
|
|
||||||
|
|
||||||
2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
|
|
||||||
"Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
|
|
||||||
With this selected, option "Full Symbolic/Source Debugging support" and
|
|
||||||
"Compile the kernel with frame pointers" are also selected.
|
|
||||||
|
|
||||||
3. Select option "KGDB: connect over (Ethernet)". Add "kgdboe=@target-IP/,@host-IP/" to
|
|
||||||
the option "Compiled-in Kernel Boot Parameter" under "Kernel hacking".
|
|
||||||
|
|
||||||
4. Connect minicom to the serial port and boot the kernel image.
|
|
||||||
|
|
||||||
5. Configure the IP "/> ifconfig eth0 target-IP"
|
|
||||||
|
|
||||||
6. Start GDB client "bfin-elf-gdb vmlinux".
|
|
||||||
|
|
||||||
7. Connect to the target "(gdb) target remote udp:target-IP:6443".
|
|
||||||
|
|
||||||
8. Set software breakpoint "(gdb) break sys_open".
|
|
||||||
|
|
||||||
9. Continue "(gdb) c".
|
|
||||||
|
|
||||||
10. Run ls in the target console "/> ls".
|
|
||||||
|
|
||||||
11. Breakpoint hits. "Breakpoint 1: sys_open(..."
|
|
||||||
|
|
||||||
12. Display local variables and function paramters.
|
|
||||||
(*) This operation gives wrong results, see known issue 1.
|
|
||||||
|
|
||||||
13. Single stepping "(gdb) si".
|
|
||||||
|
|
||||||
14. Remove breakpoint 1. "(gdb) del 1"
|
|
||||||
|
|
||||||
15. Set hardware breakpoint "(gdb) hbreak sys_open".
|
|
||||||
|
|
||||||
16. Continue "(gdb) c".
|
|
||||||
|
|
||||||
17. Run ls in the target console "/> ls".
|
|
||||||
|
|
||||||
18. Hardware breakpoint hits. "Breakpoint 1: sys_open(...".
|
|
||||||
(*) This hardware breakpoint will not be hit, see known issue 2.
|
|
||||||
|
|
||||||
19. Continue "(gdb) c".
|
|
||||||
|
|
||||||
20. Interrupt the target in GDB "Ctrl+C".
|
|
||||||
|
|
||||||
21. Detach from the target "(gdb) detach".
|
|
||||||
|
|
||||||
22. Exit GDB "(gdb) quit".
|
|
||||||
|
|
||||||
|
|
||||||
Debug over the UART:
|
|
||||||
|
|
||||||
1. Compile and install the cross platform version of gdb for blackfin, which
|
|
||||||
can be found at $(BINROOT)/bfin-elf-gdb.
|
|
||||||
|
|
||||||
2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
|
|
||||||
"Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
|
|
||||||
With this selected, option "Full Symbolic/Source Debugging support" and
|
|
||||||
"Compile the kernel with frame pointers" are also selected.
|
|
||||||
|
|
||||||
3. Select option "KGDB: connect over (UART)". Set "KGDB: UART port number" to be
|
|
||||||
a different one from the console. Don't forget to change the mode of
|
|
||||||
blackfin serial driver to PIO. Otherwise kgdb works incorrectly on UART.
|
|
||||||
|
|
||||||
4. If you want connect to kgdb when the kernel boots, enable
|
|
||||||
"KGDB: Wait for gdb connection early"
|
|
||||||
|
|
||||||
5. Compile kernel.
|
|
||||||
|
|
||||||
6. Connect minicom to the serial port of the console and boot the kernel image.
|
|
||||||
|
|
||||||
7. Start GDB client "bfin-elf-gdb vmlinux".
|
|
||||||
|
|
||||||
8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
|
|
||||||
|
|
||||||
9. Connect to the target on the second serial port "(gdb) target remote /dev/ttyS1".
|
|
||||||
|
|
||||||
10. Set software breakpoint "(gdb) break sys_open".
|
|
||||||
|
|
||||||
11. Continue "(gdb) c".
|
|
||||||
|
|
||||||
12. Run ls in the target console "/> ls".
|
|
||||||
|
|
||||||
13. A breakpoint is hit. "Breakpoint 1: sys_open(..."
|
|
||||||
|
|
||||||
14. All other operations are the same as that in KGDB over Ethernet.
|
|
||||||
|
|
||||||
|
|
||||||
Debug over the same UART as console:
|
|
||||||
|
|
||||||
1. Compile and install the cross platform version of gdb for blackfin, which
|
|
||||||
can be found at $(BINROOT)/bfin-elf-gdb.
|
|
||||||
|
|
||||||
2. Apply this patch to the 2.6.x kernel. Select the menuconfig option under
|
|
||||||
"Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
|
|
||||||
With this selected, option "Full Symbolic/Source Debugging support" and
|
|
||||||
"Compile the kernel with frame pointers" are also selected.
|
|
||||||
|
|
||||||
3. Select option "KGDB: connect over UART". Set "KGDB: UART port number" to console.
|
|
||||||
Don't forget to change the mode of blackfin serial driver to PIO.
|
|
||||||
Otherwise kgdb works incorrectly on UART.
|
|
||||||
|
|
||||||
4. If you want connect to kgdb when the kernel boots, enable
|
|
||||||
"KGDB: Wait for gdb connection early"
|
|
||||||
|
|
||||||
5. Connect minicom to the serial port and boot the kernel image.
|
|
||||||
|
|
||||||
6. (Optional) Ask target to wait for gdb connection by entering Ctrl+A. In minicom, you should enter Ctrl+A+A.
|
|
||||||
|
|
||||||
7. Start GDB client "bfin-elf-gdb vmlinux".
|
|
||||||
|
|
||||||
8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
|
|
||||||
|
|
||||||
9. Connect to the target "(gdb) target remote /dev/ttyS0".
|
|
||||||
|
|
||||||
10. Set software breakpoint "(gdb) break sys_open".
|
|
||||||
|
|
||||||
11. Continue "(gdb) c". Then enter Ctrl+C twice to stop GDB connection.
|
|
||||||
|
|
||||||
12. Run ls in the target console "/> ls". Dummy string can be seen on the console.
|
|
||||||
|
|
||||||
13. Then connect the gdb to target again. "(gdb) target remote /dev/ttyS0".
|
|
||||||
Now you will find a breakpoint is hit. "Breakpoint 1: sys_open(..."
|
|
||||||
|
|
||||||
14. All other operations are the same as that in KGDB over Ethernet. The only
|
|
||||||
difference is that after continue command in GDB, please stop GDB
|
|
||||||
connection by 2 "Ctrl+C"s and connect again after breakpoints are hit or
|
|
||||||
Ctrl+A is entered.

|
||||||
|
When: 2.6.29
|
||||||
|
Why: The old regulatory infrastructure has been replaced with a new one
|
||||||
|
which does not require statically defined regulatory domains. We do
|
||||||
|
not want to keep static regulatory domains in the kernel due to the
|
||||||
|
the dynamic nature of regulatory law and localization. We kept around
|
||||||
|
the old static definitions for the regulatory domains of:
|
||||||
|
* US
|
||||||
|
* JP
|
||||||
|
* EU
|
||||||
|
and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
|
||||||
|
set. We also kept around the ieee80211_regdom module parameter in case
|
||||||
|
some applications were relying on it. Changing regulatory domains
|
||||||
|
can now be done instead by using nl80211, as is done with iw.

Fiemap Ioctl
|
||||||
|
============
|
||||||
|
|
||||||
|
The fiemap ioctl is an efficient method for userspace to get file
|
||||||
|
extent mappings. Instead of block-by-block mapping (such as bmap), fiemap
|
||||||
|
returns a list of extents.
|
||||||
|
|
||||||
|
|
||||||
|
Request Basics
|
||||||
|
--------------
|
||||||
|
|
||||||
|
A fiemap request is encoded within struct fiemap:
|
||||||
|
|
||||||
|
struct fiemap {
|
||||||
|
__u64 fm_start; /* logical offset (inclusive) at
|
||||||
|
* which to start mapping (in) */
|
||||||
|
__u64 fm_length; /* logical length of mapping which
|
||||||
|
* userspace cares about (in) */
|
||||||
|
__u32 fm_flags; /* FIEMAP_FLAG_* flags for request (in/out) */
|
||||||
|
__u32 fm_mapped_extents; /* number of extents that were
|
||||||
|
* mapped (out) */
|
||||||
|
__u32 fm_extent_count; /* size of fm_extents array (in) */
|
||||||
|
__u32 fm_reserved;
|
||||||
|
struct fiemap_extent fm_extents[0]; /* array of mapped extents (out) */
|
||||||
|
};
|
||||||
|
|
||||||
|
|
||||||
|
fm_start, and fm_length specify the logical range within the file
|
||||||
|
which the process would like mappings for. Extents returned mirror
|
||||||
|
those on disk - that is, the logical offset of the 1st returned extent
|
||||||
|
may start before fm_start, and the range covered by the last returned
|
||||||
|
extent may end after fm_length. All offsets and lengths are in bytes.
|
||||||
|
|
||||||
|
Certain flags to modify the way in which mappings are looked up can be
|
||||||
|
set in fm_flags. If the kernel doesn't understand some particular
|
||||||
|
flags, it will return EBADR and the contents of fm_flags will contain
|
||||||
|
the set of flags which caused the error. If the kernel is compatible
|
||||||
|
with all flags passed, the contents of fm_flags will be unmodified.
|
||||||
|
It is up to userspace to determine whether rejection of a particular
|
||||||
|
flag is fatal to it's operation. This scheme is intended to allow the
|
||||||
|
fiemap interface to grow in the future but without losing
|
||||||
|
compatibility with old software.
|
||||||
|
|
||||||
|
fm_extent_count specifies the number of elements in the fm_extents[] array
|
||||||
|
that can be used to return extents. If fm_extent_count is zero, then the
|
||||||
|
fm_extents[] array is ignored (no extents will be returned), and the
|
||||||
|
fm_mapped_extents count will hold the number of extents needed in
|
||||||
|
fm_extents[] to hold the file's current mapping. Note that there is
|
||||||
|
nothing to prevent the file from changing between calls to FIEMAP.
|
||||||
|
|
||||||
|
The following flags can be set in fm_flags:
|
||||||
|
|
||||||
|
* FIEMAP_FLAG_SYNC
|
||||||
|
If this flag is set, the kernel will sync the file before mapping extents.
|
||||||
|
|
||||||
|
* FIEMAP_FLAG_XATTR
|
||||||
|
If this flag is set, the extents returned will describe the inodes
|
||||||
|
extended attribute lookup tree, instead of it's data tree.
|
||||||
|
|
||||||
|
|
||||||
|
Extent Mapping
|
||||||
|
--------------
|
||||||
|
|
||||||
|
Extent information is returned within the embedded fm_extents array
|
||||||
|
which userspace must allocate along with the fiemap structure. The
|
||||||
|
number of elements in the fiemap_extents[] array should be passed via
|
||||||
|
fm_extent_count. The number of extents mapped by kernel will be
|
||||||
|
returned via fm_mapped_extents. If the number of fiemap_extents
|
||||||
|
allocated is less than would be required to map the requested range,
|
||||||
|
the maximum number of extents that can be mapped in the fm_extent[]
|
||||||
|
array will be returned and fm_mapped_extents will be equal to
|
||||||
|
fm_extent_count. In that case, the last extent in the array will not
|
||||||
|
complete the requested range and will not have the FIEMAP_EXTENT_LAST
|
||||||
|
flag set (see the next section on extent flags).
|
||||||
|
|
||||||
|
Each extent is described by a single fiemap_extent structure as
|
||||||
|
returned in fm_extents.
|
||||||
|
|
||||||
|
struct fiemap_extent {
|
||||||
|
__u64 fe_logical; /* logical offset in bytes for the start of
|
||||||
|
* the extent */
|
||||||
|
__u64 fe_physical; /* physical offset in bytes for the start
|
||||||
|
* of the extent */
|
||||||
|
__u64 fe_length; /* length in bytes for the extent */
|
||||||
|
__u64 fe_reserved64[2];
|
||||||
|
__u32 fe_flags; /* FIEMAP_EXTENT_* flags for this extent */
|
||||||
|
__u32 fe_reserved[3];
|
||||||
|
};
|
||||||
|
|
||||||
|
All offsets and lengths are in bytes and mirror those on disk. It is valid
|
||||||
|
for an extents logical offset to start before the request or it's logical
|
||||||
|
length to extend past the request. Unless FIEMAP_EXTENT_NOT_ALIGNED is
|
||||||
|
returned, fe_logical, fe_physical, and fe_length will be aligned to the
|
||||||
|
block size of the file system. With the exception of extents flagged as
|
||||||
|
FIEMAP_EXTENT_MERGED, adjacent extents will not be merged.
|
||||||
|
|
||||||
|
The fe_flags field contains flags which describe the extent returned.
|
||||||
|
A special flag, FIEMAP_EXTENT_LAST is always set on the last extent in
|
||||||
|
the file so that the process making fiemap calls can determine when no
|
||||||
|
more extents are available, without having to call the ioctl again.
|
||||||
|
|
||||||
|
Some flags are intentionally vague and will always be set in the
|
||||||
|
presence of other more specific flags. This way a program looking for
|
||||||
|
a general property does not have to know all existing and future flags
|
||||||
|
which imply that property.
|
||||||
|
|
||||||
|
For example, if FIEMAP_EXTENT_DATA_INLINE or FIEMAP_EXTENT_DATA_TAIL
|
||||||
|
are set, FIEMAP_EXTENT_NOT_ALIGNED will also be set. A program looking
|
||||||
|
for inline or tail-packed data can key on the specific flag. Software
|
||||||
|
which simply cares not to try operating on non-aligned extents
|
||||||
|
however, can just key on FIEMAP_EXTENT_NOT_ALIGNED, and not have to
|
||||||
|
worry about all present and future flags which might imply unaligned
|
||||||
|
data. Note that the opposite is not true - it would be valid for
|
||||||
|
FIEMAP_EXTENT_NOT_ALIGNED to appear alone.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_LAST
|
||||||
|
This is the last extent in the file. A mapping attempt past this
|
||||||
|
extent will return nothing.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_UNKNOWN
|
||||||
|
The location of this extent is currently unknown. This may indicate
|
||||||
|
the data is stored on an inaccessible volume or that no storage has
|
||||||
|
been allocated for the file yet.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_DELALLOC
|
||||||
|
- This will also set FIEMAP_EXTENT_UNKNOWN.
|
||||||
|
Delayed allocation - while there is data for this extent, it's
|
||||||
|
physical location has not been allocated yet.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_ENCODED
|
||||||
|
This extent does not consist of plain filesystem blocks but is
|
||||||
|
encoded (e.g. encrypted or compressed). Reading the data in this
|
||||||
|
extent via I/O to the block device will have undefined results.
|
||||||
|
|
||||||
|
Note that it is *always* undefined to try to update the data
|
||||||
|
in-place by writing to the indicated location without the
|
||||||
|
assistance of the filesystem, or to access the data using the
|
||||||
|
information returned by the FIEMAP interface while the filesystem
|
||||||
|
is mounted. In other words, user applications may only read the
|
||||||
|
extent data via I/O to the block device while the filesystem is
|
||||||
|
unmounted, and then only if the FIEMAP_EXTENT_ENCODED flag is
|
||||||
|
clear; user applications must not try reading or writing to the
|
||||||
|
filesystem via the block device under any other circumstances.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_DATA_ENCRYPTED
|
||||||
|
- This will also set FIEMAP_EXTENT_ENCODED
|
||||||
|
The data in this extent has been encrypted by the file system.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_NOT_ALIGNED
|
||||||
|
Extent offsets and length are not guaranteed to be block aligned.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_DATA_INLINE
|
||||||
|
This will also set FIEMAP_EXTENT_NOT_ALIGNED
|
||||||
|
Data is located within a meta data block.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_DATA_TAIL
|
||||||
|
This will also set FIEMAP_EXTENT_NOT_ALIGNED
|
||||||
|
Data is packed into a block with data from other files.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_UNWRITTEN
|
||||||
|
Unwritten extent - the extent is allocated but it's data has not been
|
||||||
|
initialized. This indicates the extent's data will be all zero if read
|
||||||
|
through the filesystem but the contents are undefined if read directly from
|
||||||
|
the device.
|
||||||
|
|
||||||
|
* FIEMAP_EXTENT_MERGED
|
||||||
|
This will be set when a file does not support extents, i.e., it uses a block
|
||||||
|
based addressing scheme. Since returning an extent for each block back to
|
||||||
|
userspace would be highly inefficient, the kernel will try to merge most
|
||||||
|
adjacent blocks into 'extents'.
|
||||||
|
|
||||||
|
|
||||||
|
VFS -> File System Implementation
|
||||||
|
---------------------------------
|
||||||
|
|
||||||
|
File systems wishing to support fiemap must implement a ->fiemap callback on
|
||||||
|
their inode_operations structure. The fs ->fiemap call is responsible for
|
||||||
|
defining it's set of supported fiemap flags, and calling a helper function on
|
||||||
|
each discovered extent:
|
||||||
|
|
||||||
|
struct inode_operations {
|
||||||
|
...
|
||||||
|
|
||||||
|
int (*fiemap)(struct inode *, struct fiemap_extent_info *, u64 start,
|
||||||
|
u64 len);
|
||||||
|
|
||||||
|
->fiemap is passed struct fiemap_extent_info which describes the
|
||||||
|
fiemap request:
|
||||||
|
|
||||||
|
struct fiemap_extent_info {
|
||||||
|
unsigned int fi_flags; /* Flags as passed from user */
|
||||||
|
unsigned int fi_extents_mapped; /* Number of mapped extents */
|
||||||
|
unsigned int fi_extents_max; /* Size of fiemap_extent array */
|
||||||
|
struct fiemap_extent *fi_extents_start; /* Start of fiemap_extent array */
|
||||||
|
};
|
||||||
|
|
||||||
|
It is intended that the file system should not need to access any of this
|
||||||
|
structure directly.
|
||||||
|
|
||||||
|
|
||||||
|
Flag checking should be done at the beginning of the ->fiemap callback via the
|
||||||
|
fiemap_check_flags() helper:
|
||||||
|
|
||||||
|
int fiemap_check_flags(struct fiemap_extent_info *fieinfo, u32 fs_flags);
|
||||||
|
|
||||||
|
The struct fieinfo should be passed in as recieved from ioctl_fiemap(). The
|
||||||
|
set of fiemap flags which the fs understands should be passed via fs_flags. If
|
||||||
|
fiemap_check_flags finds invalid user flags, it will place the bad values in
|
||||||
|
fieinfo->fi_flags and return -EBADR. If the file system gets -EBADR, from
|
||||||
|
fiemap_check_flags(), it should immediately exit, returning that error back to
|
||||||
|
ioctl_fiemap().
|
||||||
|
|
||||||
|
|
||||||
|
For each extent in the request range, the file system should call
|
||||||
|
the helper function, fiemap_fill_next_extent():
|
||||||
|
|
||||||
|
int fiemap_fill_next_extent(struct fiemap_extent_info *info, u64 logical,
|
||||||
|
u64 phys, u64 len, u32 flags, u32 dev);
|
||||||
|
|
||||||
|
fiemap_fill_next_extent() will use the passed values to populate the
|
||||||
|
next free extent in the fm_extents array. 'General' extent flags will
|
||||||
|
automatically be set from specific flags on behalf of the calling file
|
||||||
|
system so that the userspace API is not broken.
|
||||||
|
|
||||||
|
fiemap_fill_next_extent() returns 0 on success, and 1 when the
|
||||||
|
user-supplied fm_extents array is full. If an error is encountered
|
||||||
|
while copying the extent to user memory, -EFAULT will be returned.

Implementation details
|
||||||
|
======================
|
||||||
|
|
||||||
|
For the interested, here's the code flow which happens inside the kernel
|
||||||
|
when you use the /dev interface to I2C:
|
||||||
|
|
||||||
|
1* Your program opens /dev/i2c-N and calls ioctl() on it, as described in
|
||||||
|
section "C example" above.
|
||||||
|
|
||||||
|
2* These open() and ioctl() calls are handled by the i2c-dev kernel
|
||||||
|
driver: see i2c-dev.c:i2cdev_open() and i2c-dev.c:i2cdev_ioctl(),
|
||||||
|
respectively. You can think of i2c-dev as a generic I2C chip driver
|
||||||
|
that can be programmed from user-space.
|
||||||
|
|
||||||
|
3* Some ioctl() calls are for administrative tasks and are handled by
|
||||||
|
i2c-dev directly. Examples include I2C_SLAVE (set the address of the
|
||||||
|
device you want to access) and I2C_PEC (enable or disable SMBus error
|
||||||
|
checking on future transactions.)
|
||||||
|
|
||||||
|
4* Other ioctl() calls are converted to in-kernel function calls by
|
||||||
|
i2c-dev. Examples include I2C_FUNCS, which queries the I2C adapter
|
||||||
|
functionality using i2c.h:i2c_get_functionality(), and I2C_SMBUS, which
|
||||||
|
performs an SMBus transaction using i2c-core.c:i2c_smbus_xfer().
|
||||||
|
|
||||||
|
The i2c-dev driver is responsible for checking all the parameters that
|
||||||
|
come from user-space for validity. After this point, there is no
|
||||||
|
difference between these calls that came from user-space through i2c-dev
|
||||||
|
and calls that would have been performed by kernel I2C chip drivers
|
||||||
|
directly. This means that I2C bus drivers don't need to implement
|
||||||
|
anything special to support access from user-space.
|
||||||
|
|
||||||
|
5* These i2c-core.c/i2c.h functions are wrappers to the actual
|
||||||
|
implementation of your I2C bus driver. Each adapter must declare
|
||||||
|
callback functions implementing these standard calls.
|
||||||
|
i2c.h:i2c_get_functionality() calls i2c_adapter.algo->functionality(),
|
||||||
|
while i2c-core.c:i2c_smbus_xfer() calls either
|
||||||
|
adapter.algo->smbus_xfer() if it is implemented, or if not,
|
||||||
|
i2c-core.c:i2c_smbus_xfer_emulated() which in turn calls
|
||||||
|
i2c_adapter.algo->master_xfer().
|
||||||
|
|
||||||
|
After your I2C bus driver has processed these requests, execution runs
|
||||||
|
up the call chain, with almost no processing done, except by i2c-dev to
|
||||||
|
package the returned data, if any, in suitable format for the ioctl.

|
|
||||||
|
ATA/ATAPI-7 specifies the IDLE IMMEDIATE command with unload feature.
|
||||||
|
Issuing this command should cause the drive to switch to idle mode and
|
||||||
|
unload disk heads. This feature is being used in modern laptops in
|
||||||
|
conjunction with accelerometers and appropriate software to implement
|
||||||
|
a shock protection facility. The idea is to stop all I/O operations on
|
||||||
|
the internal hard drive and park its heads on the ramp when critical
|
||||||
|
situations are anticipated. The desire to have such a feature
|
||||||
|
available on GNU/Linux systems has been the original motivation to
|
||||||
|
implement a generic disk head parking interface in the Linux kernel.
|
||||||
|
Please note, however, that other components have to be set up on your
|
||||||
|
system in order to get disk shock protection working (see
|
||||||
|
section 3. References below for pointers to more information about
|
||||||
|
that).
|
||||||
|
|
||||||
|
|
||||||
|
2. The interface
|
||||||
|
----------------
|
||||||
|
|
||||||
|
For each ATA device, the kernel exports the file
|
||||||
|
block/*/device/unload_heads in sysfs (here assumed to be mounted under
|
||||||
|
/sys). Access to /sys/block/*/device/unload_heads is denied with
|
||||||
|
-EOPNOTSUPP if the device does not support the unload feature.
|
||||||
|
Otherwise, writing an integer value to this file will take the heads
|
||||||
|
of the respective drive off the platter and block all I/O operations
|
||||||
|
for the specified number of milliseconds. When the timeout expires and
|
||||||
|
no further disk head park request has been issued in the meantime,
|
||||||
|
normal operation will be resumed. The maximal value accepted for a
|
||||||
|
timeout is 30000 milliseconds. Exceeding this limit will return
|
||||||
|
-EOVERFLOW, but heads will be parked anyway and the timeout will be
|
||||||
|
set to 30 seconds. However, you can always change a timeout to any
|
||||||
|
value between 0 and 30000 by issuing a subsequent head park request
|
||||||
|
before the timeout of the previous one has expired. In particular, the
|
||||||
|
total timeout can exceed 30 seconds and, more importantly, you can
|
||||||
|
cancel a previously set timeout and resume normal operation
|
||||||
|
immediately by specifying a timeout of 0. Values below -2 are rejected
|
||||||
|
with -EINVAL (see below for the special meaning of -1 and -2). If the
|
||||||
|
timeout specified for a recent head park request has not yet expired,
|
||||||
|
reading from /sys/block/*/device/unload_heads will report the number
|
||||||
|
of milliseconds remaining until normal operation will be resumed;
|
||||||
|
otherwise, reading the unload_heads attribute will return 0.
|
||||||
|
|
||||||
|
For example, do the following in order to park the heads of drive
|
||||||
|
/dev/sda and stop all I/O operations for five seconds:
|
||||||
|
|
||||||
|
# echo 5000 > /sys/block/sda/device/unload_heads
|
||||||
|
|
||||||
|
A simple
|
||||||
|
|
||||||
|
# cat /sys/block/sda/device/unload_heads
|
||||||
|
|
||||||
|
will show you how many milliseconds are left before normal operation
|
||||||
|
will be resumed.
|
||||||
|
|
||||||
|
A word of caution: The fact that the interface operates on a basis of
|
||||||
|
milliseconds may raise expectations that cannot be satisfied in
|
||||||
|
reality. In fact, the ATA specs clearly state that the time for an
|
||||||
|
unload operation to complete is vendor specific. The hint in ATA-7
|
||||||
|
that this will typically be within 500 milliseconds apparently has
|
||||||
|
been dropped in ATA-8.
|
||||||
|
|
||||||
|
There is a technical detail of this implementation that may cause some
|
||||||
|
confusion and should be discussed here. When a head park request has
|
||||||
|
been issued to a device successfully, all I/O operations on the
|
||||||
|
controller port this device is attached to will be deferred. That is
|
||||||
|
to say, any other device that may be connected to the same port will
|
||||||
|
be affected too. The only exception is that a subsequent head unload
|
||||||
|
request to that other device will be executed immediately. Further
|
||||||
|
operations on that port will be deferred until the timeout specified
|
||||||
|
for either device on the port has expired. As far as PATA (old style
|
||||||
|
IDE) configurations are concerned, there can only be two devices
|
||||||
|
attached to any single port. In SATA world we have port multipliers
|
||||||
|
which means that a user-issued head parking request to one device may
|
||||||
|
actually result in stopping I/O to a whole bunch of devices. However,
|
||||||
|
since this feature is supposed to be used on laptops and does not seem
|
||||||
|
to be very useful in any other environment, there will be mostly one
|
||||||
|
device per port. Even if the CD/DVD writer happens to be connected to
|
||||||
|
the same port as the hard drive, it generally *should* recover just
|
||||||
|
fine from the occasional buffer under-run incurred by a head park
|
||||||
|
request to the HD. Actually, when you are using an ide driver rather
|
||||||
|
than its libata counterpart (i.e. your disk is called /dev/hda
|
||||||
|
instead of /dev/sda), then parking the heads of one drive (drive X)
|
||||||
|
will generally not affect the mode of operation of another drive
|
||||||
|
(drive Y) on the same port as described above. It is only when a port
|
||||||
|
reset is required to recover from an exception on drive Y that further
|
||||||
|
I/O operations on that drive (and the reset itself) will be delayed
|
||||||
|
until drive X is no longer in the parked state.
|
||||||
|
|
||||||
|
Finally, there are some hard drives that only comply with an earlier
|
||||||
|
version of the ATA standard than ATA-7, but do support the unload
|
||||||
|
feature nonetheless. Unfortunately, there is no safe way Linux can
|
||||||
|
detect these devices, so you won't be able to write to the
|
||||||
|
unload_heads attribute. If you know that your device really does
|
||||||
|
support the unload feature (for instance, because the vendor of your
|
||||||
|
laptop or the hard drive itself told you so), then you can tell the
|
||||||
|
kernel to enable the usage of this feature for that drive by writing
|
||||||
|
the special value -1 to the unload_heads attribute:
|
||||||
|
|
||||||
|
# echo -1 > /sys/block/sda/device/unload_heads
|
||||||
|
|
||||||
|
will enable the feature for /dev/sda, and giving -2 instead of -1 will
|
||||||
|
disable it again.

There are several laptops from different vendors featuring shock

source development of the required software components so far, Linux

support for shock protection varies considerably between different

hardware implementations. Ideally, this section should contain a list

6.4 The virtual CAN driver (vcan)
|
||||||
|
|
||||||
|
Similar to the network loopback devices, vcan offers a virtual local
|
||||||
|
CAN interface. A full qualified address on CAN consists of
|
||||||
|
|
||||||
|
- a unique CAN Identifier (CAN ID)
|
||||||
|
- the CAN bus this CAN ID is transmitted on (e.g. can0)
|
||||||
|
|
||||||
|
so in common use cases more than one virtual CAN interface is needed.
|
||||||
|
|
||||||
|
The virtual CAN interfaces allow the transmission and reception of CAN
|
||||||
|
frames without real CAN controller hardware. Virtual CAN network
|
||||||
|
devices are usually named 'vcanX', like vcan0 vcan1 vcan2 ...
|
||||||
|
When compiled as a module the virtual CAN driver module is called vcan.ko
|
||||||
|
|
||||||
|
Since Linux Kernel version 2.6.24 the vcan driver supports the Kernel
|
||||||
|
netlink interface to create vcan network devices. The creation and
|
||||||
|
removal of vcan network devices can be managed with the ip(8) tool:
|
||||||
|
|
||||||
|
- Create a virtual CAN network interface:
|
||||||
|
ip link add type vcan
|
||||||
|
|
||||||
|
- Create a virtual CAN network interface with a specific name 'vcan42':
|
||||||
|
ip link add dev vcan42 type vcan
|
||||||
|
|
||||||
|
- Remove a (virtual CAN) network interface 'vcan42':
|
||||||
|
ip link del vcan42
|
||||||
|
|
||||||
|
The tool 'vcan' from the SocketCAN SVN repository on BerliOS is obsolete.
|
||||||
|
|
||||||
|
Virtual CAN network device creation in older Kernels:
|
||||||
|
In Linux Kernel versions < 2.6.24 the vcan driver creates 4 vcan
|
||||||
|
netdevices at module load time by default. This value can be changed
|
||||||
|
with the module parameter 'numdev'. E.g. 'modprobe vcan numdev=8'

Section 2: Qdisc support for multiqueue devices
|
||||||
|
|
||||||
|
-----------------------------------------------
|
||||||
|
|
||||||
|
Currently two qdiscs are optimized for multiqueue devices. The first is the
|
||||||
|
default pfifo_fast qdisc. This qdisc supports one qdisc per hardware queue.
|
||||||
|
A new round-robin qdisc, sch_multiq also supports multiple hardware queues. The
|
||||||
|
qdisc is responsible for classifying the skb's and then directing the skb's to
|
||||||
|
bands and queues based on the value in skb->queue_mapping. Use this field in
|
||||||
|
the base driver to determine which queue to send the skb to.
|
||||||
|
|
||||||
|
sch_multiq has been added for hardware that wishes to avoid head-of-line
|
||||||
|
blocking. It will cycle though the bands and verify that the hardware queue
|
||||||
|
associated with the band is not stopped prior to dequeuing a packet.
|
||||||
|
|
||||||
|
On qdisc load, the number of bands is based on the number of queues on the
|
||||||
|
hardware. Once the association is made, any skb with skb->queue_mapping set,
|
||||||
|
will be queued to the band associated with the hardware queue.
|
||||||
|
|
||||||
|
|
||||||
|
Section 3: Brief howto using MULTIQ for multiqueue devices
|
||||||
|
---------------------------------------------------------------
|
||||||
|
|
||||||
|
The userspace command 'tc,' part of the iproute2 package, is used to configure
|
||||||
|
qdiscs. To add the MULTIQ qdisc to your network device, assuming the device
|
||||||
|
is called eth0, run the following command:
|
||||||
|
|
||||||
|
# tc qdisc add dev eth0 root handle 1: multiq
|
||||||
|
|
||||||
|
The qdisc will allocate the number of bands to equal the number of queues that
|
||||||
|
the device reports, and bring the qdisc online. Assuming eth0 has 4 Tx
|
||||||
|
queues, the band mapping would look like:
|
||||||
|
|
||||||
|
band 0 => queue 0
|
||||||
|
band 1 => queue 1
|
||||||
|
band 2 => queue 2
|
||||||
|
band 3 => queue 3
|
||||||
|
|
||||||
|
Traffic will begin flowing through each queue based on either the simple_tx_hash
|
||||||
|
function or based on netdev->select_queue() if you have it defined.
|
||||||
|
|
||||||
|
The behavior of tc filters remains the same. However a new tc action,
|
||||||
|
skbedit, has been added. Assuming you wanted to route all traffic to a
|
||||||
|
specific host, for example 192.168.0.3, through a specific queue you could use
|
||||||
|
this action and establish a filter such as:
|
||||||
|
|
||||||
|
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \
|
||||||
|
match ip dst 192.168.0.3 \
|
||||||
|
action skbedit queue_mapping 3

Linux Phonet protocol family
|
||||||
|
============================
|
||||||
|
|
||||||
|
Introduction
|
||||||
|
------------
|
||||||
|
|
||||||
|
Phonet is a packet protocol used by Nokia cellular modems for both IPC
|
||||||
|
and RPC. With the Linux Phonet socket family, Linux host processes can
|
||||||
|
receive and send messages from/to the modem, or any other external
|
||||||
|
device attached to the modem. The modem takes care of routing.
|
||||||
|
|
||||||
|
Phonet packets can be exchanged through various hardware connections
|
||||||
|
depending on the device, such as:
|
||||||
|
- USB with the CDC Phonet interface,
|
||||||
|
- infrared,
|
||||||
|
- Bluetooth,
|
||||||
|
- an RS232 serial port (with a dedicated "FBUS" line discipline),
|
||||||
|
- the SSI bus with some TI OMAP processors.
|
||||||
|
|
||||||
|
|
||||||
|
Packets format
|
||||||
|
--------------
|
||||||
|
|
||||||
|
Phonet packets have a common header as follows:
|
||||||
|
|
||||||
|
struct phonethdr {
|
||||||
|
uint8_t pn_media; /* Media type (link-layer identifier) */
|
||||||
|
uint8_t pn_rdev; /* Receiver device ID */
|
||||||
|
uint8_t pn_sdev; /* Sender device ID */
|
||||||
|
uint8_t pn_res; /* Resource ID or function */
|
||||||
|
uint16_t pn_length; /* Big-endian message byte length (minus 6) */
|
||||||
|
uint8_t pn_robj; /* Receiver object ID */
|
||||||
|
uint8_t pn_sobj; /* Sender object ID */
|
||||||
|
};
|
||||||
|
|
||||||
|
On Linux, the link-layer header includes the pn_media byte (see below).
|
||||||
|
The next 7 bytes are part of the network-layer header.
|
||||||
|
|
||||||
|
The device ID is split: the 6 higher-order bits consitute the device
|
||||||
|
address, while the 2 lower-order bits are used for multiplexing, as are
|
||||||
|
the 8-bit object identifiers. As such, Phonet can be considered as a
|
||||||
|
network layer with 6 bits of address space and 10 bits for transport
|
||||||
|
protocol (much like port numbers in IP world).
|
||||||
|
|
||||||
|
The modem always has address number zero. All other device have a their
|
||||||
|
own 6-bit address.
|
||||||
|
|
||||||
|
|
||||||
|
Link layer
|
||||||
|
----------
|
||||||
|
|
||||||
|
Phonet links are always point-to-point links. The link layer header
|
||||||
|
consists of a single Phonet media type byte. It uniquely identifies the
|
||||||
|
link through which the packet is transmitted, from the modem's
|
||||||
|
perspective. Each Phonet network device shall prepend and set the media
|
||||||
|
type byte as appropriate. For convenience, a common phonet_header_ops
|
||||||
|
link-layer header operations structure is provided. It sets the
|
||||||
|
media type according to the network device hardware address.
|
||||||
|
|
||||||
|
Linux Phonet network interfaces support a dedicated link layer packets
|
||||||
|
type (ETH_P_PHONET) which is out of the Ethernet type range. They can
|
||||||
|
only send and receive Phonet packets.
|
||||||
|
|
||||||
|
The virtual TUN tunnel device driver can also be used for Phonet. This
|
||||||
|
requires IFF_TUN mode, _without_ the IFF_NO_PI flag. In this case,
|
||||||
|
there is no link-layer header, so there is no Phonet media type byte.
|
||||||
|
|
||||||
|
Note that Phonet interfaces are not allowed to re-order packets, so
|
||||||
|
only the (default) Linux FIFO qdisc should be used with them.
|
||||||
|
|
||||||
|
|
||||||
|
Network layer
|
||||||
|
-------------
|
||||||
|
|
||||||
|
The Phonet socket address family maps the Phonet packet header:
|
||||||
|
|
||||||
|
struct sockaddr_pn {
|
||||||
|
sa_family_t spn_family; /* AF_PHONET */
|
||||||
|
uint8_t spn_obj; /* Object ID */
|
||||||
|
uint8_t spn_dev; /* Device ID */
|
||||||
|
uint8_t spn_resource; /* Resource or function */
|
||||||
|
uint8_t spn_zero[...]; /* Padding */
|
||||||
|
};
|
||||||
|
|
||||||
|
The resource field is only used when sending and receiving;
|
||||||
|
It is ignored by bind() and getsockname().
|
||||||
|
|
||||||
|
|
||||||
|
Low-level datagram protocol
|
||||||
|
---------------------------
|
||||||
|
|
||||||
|
Applications can send Phonet messages using the Phonet datagram socket
|
||||||
|
protocol from the PF_PHONET family. Each socket is bound to one of the
|
||||||
|
2^10 object IDs available, and can send and receive packets with any
|
||||||
|
other peer.
|
||||||
|
|
||||||
|
struct sockaddr_pn addr = { .spn_family = AF_PHONET, };
|
||||||
|
ssize_t len;
|
||||||
|
socklen_t addrlen = sizeof(addr);
|
||||||
|
int fd;
|
||||||
|
|
||||||
|
fd = socket(PF_PHONET, SOCK_DGRAM, 0);
|
||||||
|
bind(fd, (struct sockaddr *)&addr, sizeof(addr));
|
||||||
|
/* ... */
|
||||||
|
|
||||||
|
sendto(fd, msg, msglen, 0, (struct sockaddr *)&addr, sizeof(addr));
|
||||||
|
len = recvfrom(fd, buf, sizeof(buf), 0,
|
||||||
|
(struct sockaddr *)&addr, &addrlen);
|
||||||
|
|
||||||
|
This protocol follows the SOCK_DGRAM connection-less semantics.
|
||||||
|
However, connect() and getpeername() are not supported, as they did
|
||||||
|
not seem useful with Phonet usages (could be added easily).
|
||||||
|
|
||||||
|
|
||||||
|
Phonet Pipe protocol
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
The Phonet Pipe protocol is a simple sequenced packets protocol
|
||||||
|
with end-to-end congestion control. It uses the passive listening
|
||||||
|
socket paradigm. The listening socket is bound to an unique free object
|
||||||
|
ID. Each listening socket can handle up to 255 simultaneous
|
||||||
|
connections, one per accept()'d socket.
|
||||||
|
|
||||||
|
int lfd, cfd;
|
||||||
|
|
||||||
|
lfd = socket(PF_PHONET, SOCK_SEQPACKET, PN_PROTO_PIPE);
|
||||||
|
listen (lfd, INT_MAX);
|
||||||
|
|
||||||
|
/* ... */
|
||||||
|
cfd = accept(lfd, NULL, NULL);
|
||||||
|
for (;;)
|
||||||
|
{
|
||||||
|
char buf[...];
|
||||||
|
ssize_t len = read(cfd, buf, sizeof(buf));
|
||||||
|
|
||||||
|
/* ... */
|
||||||
|
|
||||||
|
write(cfd, msg, msglen);
|
||||||
|
}
|
||||||
|
|
||||||
|
Connections are established between two endpoints by a "third party"
|
||||||
|
application. This means that both endpoints are passive; so connect()
|
||||||
|
is not possible.
|
||||||
|
|
||||||
|
WARNING:
|
||||||
|
When polling a connected pipe socket for writability, there is an
|
||||||
|
intrinsic race condition whereby writability might be lost between the
|
||||||
|
polling and the writing system calls. In this case, the socket will
|
||||||
|
block until write because possible again, unless non-blocking mode
|
||||||
|
becomes enabled.
|
||||||
|
|
||||||
|
|
||||||
|
The pipe protocol provides two socket options at the SOL_PNPIPE level:
|
||||||
|
|
||||||
|
PNPIPE_ENCAP accepts one integer value (int) of:
|
||||||
|
|
||||||
|
PNPIPE_ENCAP_NONE: The socket operates normally (default).
|
||||||
|
|
||||||
|
PNPIPE_ENCAP_IP: The socket is used as a backend for a virtual IP
|
||||||
|
interface. This requires CAP_NET_ADMIN capability. GPRS data
|
||||||
|
support on Nokia modems can use this. Note that the socket cannot
|
||||||
|
be reliably poll()'d or read() from while in this mode.
|
||||||
|
|
||||||
|
PNPIPE_IFINDEX is a read-only integer value. It contains the
|
||||||
|
interface index of the network interface created by PNPIPE_ENCAP,
|
||||||
|
or zero if encapsulation is off.

Due to the dynamic nature of regulatory domains we keep them
|
||||||
|
in userspace and provide a framework for userspace to upload
|
||||||
|
to the kernel one regulatory domain to be used as the central
|
||||||
|
core regulatory domain all wireless devices should adhere to.
|
||||||
|
|
||||||
|
How to get regulatory domains to the kernel
|
||||||
|
-------------------------------------------
|
||||||
|
|
||||||
|
Userspace gets a regulatory domain in the kernel by having
|
||||||
|
a userspace agent build it and send it via nl80211. Only
|
||||||
|
expected regulatory domains will be respected by the kernel.
|
||||||
|
|
||||||
|
A currently available userspace agent which can accomplish this
|
||||||
|
is CRDA - central regulatory domain agent. Its documented here:
|
||||||
|
|
||||||
|
http://wireless.kernel.org/en/developers/Regulatory/CRDA
|
||||||
|
|
||||||
|
Essentially the kernel will send a udev event when it knows
|
||||||
|
it needs a new regulatory domain. A udev rule can be put in place
|
||||||
|
to trigger crda to send the respective regulatory domain for a
|
||||||
|
specific ISO/IEC 3166 alpha2.
|
||||||
|
|
||||||
|
Below is an example udev rule which can be used:
|
||||||
|
|
||||||
|
# Example file, should be put in /etc/udev/rules.d/regulatory.rules
|
||||||
|
KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"
|
||||||
|
|
||||||
|
The alpha2 is passed as an environment variable under the variable COUNTRY.
|
||||||
|
|
||||||
|
Who asks for regulatory domains?
|
||||||
|
--------------------------------
|
||||||
|
|
||||||
|
* Users
|
||||||
|
|
||||||
|
Users can use iw:
|
||||||
|
|
||||||
|
http://wireless.kernel.org/en/users/Documentation/iw
|
||||||
|
|
||||||
|
An example:
|
||||||
|
|
||||||
|
# set regulatory domain to "Costa Rica"
|
||||||
|
iw reg set CR
|
||||||
|
|
||||||
|
This will request the kernel to set the regulatory domain to
|
||||||
|
the specificied alpha2. The kernel in turn will then ask userspace
|
||||||
|
to provide a regulatory domain for the alpha2 specified by the user
|
||||||
|
by sending a uevent.
|
||||||
|
|
||||||
|
* Wireless subsystems for Country Information elements
|
||||||
|
|
||||||
|
The kernel will send a uevent to inform userspace a new
|
||||||
|
regulatory domain is required. More on this to be added
|
||||||
|
as its integration is added.
|
||||||
|
|
||||||
|
* Drivers
|
||||||
|
|
||||||
|
If drivers determine they need a specific regulatory domain
|
||||||
|
set they can inform the wireless core using regulatory_hint().
|
||||||
|
They have two options -- they either provide an alpha2 so that
|
||||||
|
crda can provide back a regulatory domain for that country or
|
||||||
|
they can build their own regulatory domain based on internal
|
||||||
|
custom knowledge so the wireless core can respect it.
|
||||||
|
|
||||||
|
*Most* drivers will rely on the first mechanism of providing a
|
||||||
|
regulatory hint with an alpha2. For these drivers there is an additional
|
||||||
|
check that can be used to ensure compliance based on custom EEPROM
|
||||||
|
regulatory data. This additional check can be used by drivers by
|
||||||
|
registering on its struct wiphy a reg_notifier() callback. This notifier
|
||||||
|
is called when the core's regulatory domain has been changed. The driver
|
||||||
|
can use this to review the changes made and also review who made them
|
||||||
|
(driver, user, country IE) and determine what to allow based on its
|
||||||
|
internal EEPROM data. Devices drivers wishing to be capable of world
|
||||||
|
roaming should use this callback. More on world roaming will be
|
||||||
|
added to this document when its support is enabled.
|
||||||
|
|
||||||
|
Device drivers who provide their own built regulatory domain
|
||||||
|
do not need a callback as the channels registered by them are
|
||||||
|
the only ones that will be allowed and therefore *additional*
|
||||||
|
cannels cannot be enabled.
|
||||||
|
|
||||||
|
Example code - drivers hinting an alpha2:
|
||||||
|
------------------------------------------
|
||||||
|
|
||||||
|
This example comes from the zd1211rw device driver. You can start
|
||||||
|
by having a mapping of your device's EEPROM country/regulatory
|
||||||
|
domain value to to a specific alpha2 as follows:
|
||||||
|
|
||||||
|
static struct zd_reg_alpha2_map reg_alpha2_map[] = {
|
||||||
|
{ ZD_REGDOMAIN_FCC, "US" },
|
||||||
|
{ ZD_REGDOMAIN_IC, "CA" },
|
||||||
|
{ ZD_REGDOMAIN_ETSI, "DE" }, /* Generic ETSI, use most restrictive */
|
||||||
|
{ ZD_REGDOMAIN_JAPAN, "JP" },
|
||||||
|
{ ZD_REGDOMAIN_JAPAN_ADD, "JP" },
|
||||||
|
{ ZD_REGDOMAIN_SPAIN, "ES" },
|
||||||
|
{ ZD_REGDOMAIN_FRANCE, "FR" },
|
||||||
|
|
||||||
|
Then you can define a routine to map your read EEPROM value to an alpha2,
|
||||||
|
as follows:
|
||||||
|
|
||||||
|
static int zd_reg2alpha2(u8 regdomain, char *alpha2)
|
||||||
|
{
|
||||||
|
unsigned int i;
|
||||||
|
struct zd_reg_alpha2_map *reg_map;
|
||||||
|
for (i = 0; i < ARRAY_SIZE(reg_alpha2_map); i++) {
|
||||||
|
reg_map = ®_alpha2_map[i];
|
||||||
|
if (regdomain == reg_map->reg) {
|
||||||
|
alpha2[0] = reg_map->alpha2[0];
|
||||||
|
alpha2[1] = reg_map->alpha2[1];
|
||||||
|
return 0;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
return 1;
|
||||||
|
}
|
||||||
|
|
||||||
|
Lastly, you can then hint to the core of your discovered alpha2, if a match
|
||||||
|
was found. You need to do this after you have registered your wiphy. You
|
||||||
|
are expected to do this during initialization.
|
||||||
|
|
||||||
|
r = zd_reg2alpha2(mac->regdomain, alpha2);
|
||||||
|
if (!r)
|
||||||
|
regulatory_hint(hw->wiphy, alpha2, NULL);
|
||||||
|
|
||||||
|
Example code - drivers providing a built in regulatory domain:
|
||||||
|
--------------------------------------------------------------
|
||||||
|
|
||||||
|
If you have regulatory information you can obtain from your
|
||||||
|
driver and you *need* to use this we let you build a regulatory domain
|
||||||
|
structure and pass it to the wireless core. To do this you should
|
||||||
|
kmalloc() a structure big enough to hold your regulatory domain
|
||||||
|
structure and you should then fill it with your data. Finally you simply
|
||||||
|
call regulatory_hint() with the regulatory domain structure in it.
|
||||||
|
|
||||||
|
Bellow is a simple example, with a regulatory domain cached using the stack.
|
||||||
|
Your implementation may vary (read EEPROM cache instead, for example).
|
||||||
|
|
||||||
|
Example cache of some regulatory domain
|
||||||
|
|
||||||
|
struct ieee80211_regdomain mydriver_jp_regdom = {
|
||||||
|
.n_reg_rules = 3,
|
||||||
|
.alpha2 = "JP",
|
||||||
|
//.alpha2 = "99", /* If I have no alpha2 to map it to */
|
||||||
|
.reg_rules = {
|
||||||
|
/* IEEE 802.11b/g, channels 1..14 */
|
||||||
|
REG_RULE(2412-20, 2484+20, 40, 6, 20, 0),
|

|

|
NL80211_RRF_DFS),
|
||||||
|
}

};
|

}

Transparent proxy support
|
||||||
|
=========================
|
||||||
|
|
||||||
|
This feature adds Linux 2.2-like transparent proxy support to current kernels.
|
||||||
|
To use it, enable NETFILTER_TPROXY, the socket match and the TPROXY target in
|
||||||
|
your kernel config. You will need policy routing too, so be sure to enable that
|
||||||
|
as well.
|
||||||
|
|
||||||
|
|
||||||
|
1. Making non-local sockets work
|
||||||
|
================================
|
||||||
|
|
||||||
|
The idea is that you identify packets with destination address matching a local
|
||||||
|
socket on your box, set the packet mark to a certain value, and then match on that
|
||||||
|
value using policy routing to have those packets delivered locally:
|
||||||
|
|
||||||
|
# iptables -t mangle -N DIVERT
|
||||||
|
# iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
|
||||||
|
# iptables -t mangle -A DIVERT -j MARK --set-mark 1
|
||||||
|
# iptables -t mangle -A DIVERT -j ACCEPT
|
||||||
|
|
||||||
|
# ip rule add fwmark 1 lookup 100
|
||||||
|
# ip route add local 0.0.0.0/0 dev lo table 100
|
||||||
|
|
||||||
|
Because of certain restrictions in the IPv4 routing output code you'll have to
|
||||||
|
modify your application to allow it to send datagrams _from_ non-local IP
|
||||||
|
addresses. All you have to do is enable the (SOL_IP, IP_TRANSPARENT) socket
|
||||||
|
option before calling bind:
|
||||||
|
|
||||||
|
fd = socket(AF_INET, SOCK_STREAM, 0);
|
||||||
|
/* - 8< -*/
|
||||||
|
int value = 1;
|
||||||
|
setsockopt(fd, SOL_IP, IP_TRANSPARENT, &value, sizeof(value));
|
||||||
|
/* - 8< -*/
|
||||||
|
name.sin_family = AF_INET;
|
||||||
|
name.sin_port = htons(0xCAFE);
|
||||||
|
name.sin_addr.s_addr = htonl(0xDEADBEEF);
|
||||||
|
bind(fd, &name, sizeof(name));
|
||||||
|
|
||||||
|
A trivial patch for netcat is available here:
|
||||||
|
http://people.netfilter.org/hidden/tproxy/netcat-ip_transparent-support.patch
|
||||||
|
|
||||||
|
|
||||||
|
2. Redirecting traffic
|
||||||
|
======================
|
||||||
|
|
||||||
|
Transparent proxying often involves "intercepting" traffic on a router. This is
|
||||||
|
usually done with the iptables REDIRECT target; however, there are serious
|
||||||
|
limitations of that method. One of the major issues is that it actually
|
||||||
|
modifies the packets to change the destination address -- which might not be
|
||||||
|
acceptable in certain situations. (Think of proxying UDP for example: you won't
|
||||||
|
be able to find out the original destination address. Even in case of TCP
|
||||||
|
getting the original destination address is racy.)
|
||||||
|
|
||||||
|
The 'TPROXY' target provides similar functionality without relying on NAT. Simply
|
||||||
|
add rules like this to the iptables ruleset above:
|
||||||
|
|
||||||
|
# iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY \
|
||||||
|
--tproxy-mark 0x1/0x1 --on-port 50080
|
||||||
|
|
||||||
|
Note that for this to work you'll have to modify the proxy to enable (SOL_IP,
|
||||||
|
IP_TRANSPARENT) for the listening socket.
|
||||||
|
|
||||||
|
|
||||||
|
3. Iptables extensions
|
||||||
|
======================
|
||||||
|
|
||||||
|
To use tproxy you'll need to have the 'socket' and 'TPROXY' modules
|
||||||
|
compiled for iptables. A patched version of iptables is available
|
||||||
|
here: http://git.balabit.hu/?p=bazsi/iptables-tproxy.git
|
||||||
|
|
||||||
|
|
||||||
|
4. Application support

||||||

||||||

3. Power Domain constraint setting.
|
|
||||||
===================================
|
|
||||||
Each power domain within a system has physical constraints on voltage and
|
|
||||||
current. This must be defined in software so that the power domain is always
|
|
||||||
operated within specifications.
|
|
||||||
|
|
||||||
Consider the following machine (again) :-
|
|
||||||
|
|
||||||
Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
|
|
||||||
|
|
|
||||||
+-> [Consumer B @ 3.3V]
|
|
||||||
|
|
||||||
This gives us two regulators and two power domains:
|
|
||||||
|
|
||||||
Domain 1: Regulator-2, Consumer B.

|
CFS Scheduler
|
||||||
|
=============
|
||||||
80% of CFS's design can be summed up in a single sentence: CFS basically
|
|
||||||
models an "ideal, precise multi-tasking CPU" on real hardware.
|
|
||||||
|
|
||||||
"Ideal multi-tasking CPU" is a (non-existent :-)) CPU that has 100%
|
|
||||||
physical power and which can run each task at precise equal speed, in
|
|
||||||
parallel, each at 1/nr_running speed. For example: if there are 2 tasks
|
|
||||||
running then it runs each at 50% physical power - totally in parallel.
|
|
||||||
|
|
||||||
On real hardware, we can run only a single task at once, so while that
|
|
||||||
one task runs, the other tasks that are waiting for the CPU are at a
|
|
||||||
disadvantage - the current task gets an unfair amount of CPU time. In
|
|
||||||
CFS this fairness imbalance is expressed and tracked via the per-task
|
|
||||||
p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of
|
|
||||||
time the task should now run on the CPU for it to become completely fair
|
|
||||||
and balanced.
|
|
||||||
|
|
||||||
( small detail: on 'ideal' hardware, the p->wait_runtime value would
|
|
||||||
always be zero - no task would ever get 'out of balance' from the
|
|
||||||
'ideal' share of CPU time. )
|
|
||||||
|
|
||||||
CFS's task picking logic is based on this p->wait_runtime value and it
|
|
||||||
is thus very simple: it always tries to run the task with the largest
|
|
||||||
p->wait_runtime value. In other words, CFS tries to run the task with
|
|
||||||
the 'gravest need' for more CPU time. So CFS always tries to split up
|
|
||||||
CPU time between runnable tasks as close to 'ideal multitasking
|
|
||||||
hardware' as possible.
|
|
||||||
|
|
||||||
Most of the rest of CFS's design just falls out of this really simple
|
|
||||||
concept, with a few add-on embellishments like nice levels,
|
|
||||||
multiprocessing and various algorithm variants to recognize sleepers.
|
|
||||||
|
|
||||||
In practice it works like this: the system runs a task a bit, and when
|
|
||||||
the task schedules (or a scheduler tick happens) the task's CPU usage is
|
|
||||||
'accounted for': the (small) time it just spent using the physical CPU
|
|
||||||
is deducted from p->wait_runtime. [minus the 'fair share' it would have
|
|
||||||
gotten anyway]. Once p->wait_runtime gets low enough so that another
|
|
||||||
task becomes the 'leftmost task' of the time-ordered rbtree it maintains
|
|
||||||
(plus a small amount of 'granularity' distance relative to the leftmost
|
|
||||||
task so that we do not over-schedule tasks and trash the cache) then the
|
|
||||||
new leftmost task is picked and the current task is preempted.
|
|
||||||
|
|
||||||
The rq->fair_clock value tracks the 'CPU time a runnable task would have
|
|
||||||
fairly gotten, had it been runnable during that time'. So by using
|
|
||||||
rq->fair_clock values we can accurately timestamp and measure the
|
|
||||||
'expected CPU time' a task should have gotten. All runnable tasks are
|
|
||||||
sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and
|
|
||||||
CFS picks the 'leftmost' task and sticks to it. As the system progresses
|
|
||||||
forwards, newly woken tasks are put into the tree more and more to the
|
|
||||||
right - slowly but surely giving a chance for every task to become the
|
|
||||||
'leftmost task' and thus get on the CPU within a deterministic amount of
|
|
||||||
time.
|
|
||||||
|
|
||||||
Some implementation details:
|
|
||||||
|
|
||||||
- the introduction of Scheduling Classes: an extensible hierarchy of
|
|
||||||
scheduler modules. These modules encapsulate scheduling policy
|
|
||||||
details and are handled by the scheduler core without the core
|
|
||||||
code assuming about them too much.
|
|
||||||
|
|
||||||
- sched_fair.c implements the 'CFS desktop scheduler': it is a
|
|
||||||
replacement for the vanilla scheduler's SCHED_OTHER interactivity
|
|
||||||
code.
|
|
||||||
|
|
||||||
I'd like to give credit to Con Kolivas for the general approach here:
|
|
||||||
he has proven via RSDL/SD that 'fair scheduling' is possible and that
|
|
||||||
it results in better desktop scheduling. Kudos Con!
|
|
||||||
|
|
||||||
The CFS patch uses a completely different approach and implementation
|
|
||||||
from RSDL/SD. My goal was to make CFS's interactivity quality exceed
|
|
||||||
that of RSDL/SD, which is a high standard to meet :-) Testing
|
|
||||||
feedback is welcome to decide this one way or another. [ and, in any
|
|
||||||
case, all of SD's logic could be added via a kernel/sched_sd.c module
|
|
||||||
as well, if Con is interested in such an approach. ]
|
|
||||||
|
|
||||||
CFS's design is quite radical: it does not use runqueues, it uses a
|
|
||||||
time-ordered rbtree to build a 'timeline' of future task execution,
|
|
||||||
and thus has no 'array switch' artifacts (by which both the vanilla
|
|
||||||
scheduler and RSDL/SD are affected).
|
|
||||||
|
|
||||||
CFS uses nanosecond granularity accounting and does not rely on any
|
|
||||||
jiffies or other HZ detail. Thus the CFS scheduler has no notion of
|
|
||||||
'timeslices' and has no heuristics whatsoever. There is only one
|
|
||||||
central tunable (you have to switch on CONFIG_SCHED_DEBUG):
|
|
||||||
|
|
||||||
/proc/sys/kernel/sched_granularity_ns
|
|
||||||
|
|
||||||
which can be used to tune the scheduler from 'desktop' (low
|
|
||||||
latencies) to 'server' (good batching) workloads. It defaults to a
|
|
||||||
setting suitable for desktop workloads. SCHED_BATCH is handled by the
|
|
||||||
CFS scheduler module too.
|
|
||||||
|
|
||||||
Due to its design, the CFS scheduler is not prone to any of the
|
|
||||||
'attacks' that exist today against the heuristics of the stock
|
|
||||||
scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all
|
|
||||||
work fine and do not impact interactivity and produce the expected
|
|
||||||
behavior.
|
|
||||||
|
|
||||||
the CFS scheduler has a much stronger handling of nice levels and
|
|
||||||
SCHED_BATCH: both types of workloads should be isolated much more
|
|
||||||
agressively than under the vanilla scheduler.
|
|
||||||
|
|
||||||
( another detail: due to nanosec accounting and timeline sorting,
|
|
||||||
sched_yield() support is very simple under CFS, and in fact under
|
|
||||||
CFS sched_yield() behaves much better than under any other
|
|
||||||
scheduler i have tested so far. )
|
|
||||||
|
|
||||||
- sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler
|
|
||||||
way than the vanilla scheduler does. It uses 100 runqueues (for all
|
|
||||||
100 RT priority levels, instead of 140 in the vanilla scheduler)
|
|
||||||
and it needs no expired array.
|
|
||||||
|
|
||||||
- reworked/sanitized SMP load-balancing: the runqueue-walking
|
|
||||||
assumptions are gone from the load-balancing code now, and
|
|
||||||
iterators of the scheduling modules are used. The balancing code got
|
|
||||||
quite a bit simpler as a result.

|
||||||

Group scheduler extension to CFS
|
1. OVERVIEW
|
||||||
================================
|
|
||||||
|
|
||||||
Normally the scheduler operates on individual tasks and strives to provide
|
CFS stands for "Completely Fair Scheduler," and is the new "desktop" process
|
||||||
fair CPU time to each task. Sometimes, it may be desirable to group tasks
|
scheduler implemented by Ingo Molnar and merged in Linux 2.6.23. It is the
|
||||||
and provide fair CPU time to each such task group. For example, it may
|
replacement for the previous vanilla scheduler's SCHED_OTHER interactivity
|
||||||
be desirable to first provide fair CPU time to each user on the system
|
code.
|
||||||
and then to each task belonging to a user.
|
|
||||||
|
|
||||||
CONFIG_FAIR_GROUP_SCHED strives to achieve exactly that. It lets

|
||||||

|
||||||
groups. At present, there are two (mutually exclusive) mechanisms to group
|
|
||||||
tasks for CPU bandwidth control purpose:

|
||||||
|
|
||||||
- Based on user id (CONFIG_FAIR_USER_SCHED)

|
||||||
of tasks, using the "cgroup" pseudo filesystem. See
|
|
||||||
Documentation/cgroups.txt for more information about this
|
On real hardware, we can run only a single task at once, so we have to
|
||||||
filesystem.
|
introduce the concept of "virtual runtime." The virtual runtime of a task
|
||||||
|
specifies when its next timeslice would start execution on the ideal
|
||||||
|
multi-tasking CPU described above. In practice, the virtual runtime of a task
|
||||||
|
is its actual runtime normalized to the total number of running tasks.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
2. FEW IMPLEMENTATION DETAILS
|
||||||
|
|
||||||
|
In CFS the virtual runtime is expressed and tracked via the per-task
|
||||||
|
p->se.vruntime (nanosec-unit) value. This way, it's possible to accurately
|
||||||
|
timestamp and measure the "expected CPU time" a task should have gotten.
|
||||||
|
|
||||||
|
[ small detail: on "ideal" hardware, at any time all tasks would have the same
|
||||||
|
p->se.vruntime value --- i.e., tasks would execute simultaneously and no task
|
||||||
|
would ever get "out of balance" from the "ideal" share of CPU time. ]
|
||||||
|
|
||||||
|
CFS's task picking logic is based on this p->se.vruntime value and it is thus
|
||||||
|
very simple: it always tries to run the task with the smallest p->se.vruntime
|
||||||
|
value (i.e., the task which executed least so far). CFS always tries to split
|
||||||
|
up CPU time between runnable tasks as close to "ideal multitasking hardware" as
|
||||||
|
possible.
|
||||||
|
|
||||||
|
Most of the rest of CFS's design just falls out of this really simple concept,
|
||||||
|
with a few add-on embellishments like nice levels, multiprocessing and various
|
||||||
|
algorithm variants to recognize sleepers.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
3. THE RBTREE
|
||||||
|
|
||||||
|
CFS's design is quite radical: it does not use the old data structures for the
|
||||||
|
runqueues, but it uses a time-ordered rbtree to build a "timeline" of future
|
||||||
|
task execution, and thus has no "array switch" artifacts (by which both the
|
||||||
|
previous vanilla scheduler and RSDL/SD are affected).
|
||||||
|
|
||||||
|
CFS also maintains the rq->cfs.min_vruntime value, which is a monotonic
|
||||||
|
increasing value tracking the smallest vruntime among all tasks in the
|
||||||
|
runqueue. The total amount of work done by the system is tracked using
|
||||||
|
min_vruntime; that value is used to place newly activated entities on the left
|
||||||
|
side of the tree as much as possible.
|
||||||
|
|
||||||
|
The total number of running tasks in the runqueue is accounted through the
|
||||||
|
rq->cfs.load value, which is the sum of the weights of the tasks queued on the
|
||||||
|
runqueue.
|
||||||
|
|
||||||
|
CFS maintains a time-ordered rbtree, where all runnable tasks are sorted by the
|
||||||
|
p->se.vruntime key (there is a subtraction using rq->cfs.min_vruntime to
|
||||||
|
account for possible wraparounds). CFS picks the "leftmost" task from this
|
||||||
|
tree and sticks to it.
|
||||||
|
As the system progresses forwards, the executed tasks are put into the tree
|
||||||
|
more and more to the right --- slowly but surely giving a chance for every task
|
||||||
|
to become the "leftmost task" and thus get on the CPU within a deterministic
|
||||||
|
amount of time.
|
||||||
|
|
||||||
|
Summing up, CFS works like this: it runs a task a bit, and when the task
|
||||||
|
schedules (or a scheduler tick happens) the task's CPU usage is "accounted
|
||||||
|
for": the (small) time it just spent using the physical CPU is added to
|
||||||
|
p->se.vruntime. Once p->se.vruntime gets high enough so that another task
|
||||||
|
becomes the "leftmost task" of the time-ordered rbtree it maintains (plus a
|
||||||
|
small amount of "granularity" distance relative to the leftmost task so that we
|
||||||
|
do not over-schedule tasks and trash the cache), then the new leftmost task is
|
||||||
|
picked and the current task is preempted.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||

4. SOME FEATURES OF CFS
|
||||||
|
|
||||||
|

|
||||||

other HZ detail. Thus the CFS scheduler has no notion of "timeslices" in the
|
||||||
|
way the previous scheduler had, and has no heuristics whatsoever. There is
|
||||||
|
only one central tunable (you have to switch on CONFIG_SCHED_DEBUG):
|
||||||
|
|
||||||
|
/proc/sys/kernel/sched_granularity_ns
|
||||||
|
|
||||||
|
which can be used to tune the scheduler from "desktop" (i.e., low latencies) to
|
||||||
|
"server" (i.e., good batching) workloads. It defaults to a setting suitable
|
||||||
|
for desktop workloads. SCHED_BATCH is handled by the CFS scheduler module too.
|
||||||
|
|
||||||
|
Due to its design, the CFS scheduler is not prone to any of the "attacks" that
|
||||||
|
exist today against the heuristics of the stock scheduler: fiftyp.c, thud.c,
|
||||||
|
chew.c, ring-test.c, massive_intr.c all work fine and do not impact
|
||||||
|
interactivity and produce the expected behavior.
|
||||||
|
|
||||||
|
The CFS scheduler has a much stronger handling of nice levels and SCHED_BATCH
|
||||||
|
than the previous vanilla scheduler: both types of workloads are isolated much
|
||||||
|
more aggressively.
|
||||||
|
|
||||||
|
SMP load-balancing has been reworked/sanitized: the runqueue-walking
|
||||||
|
assumptions are gone from the load-balancing code now, and iterators of the
|
||||||
|
scheduling modules are used. The balancing code got quite a bit simpler as a
|
||||||
|
result.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
5. Scheduling policies
|
||||||
|
|
||||||
|
CFS implements three scheduling policies:
|
||||||
|
|
||||||
|
- SCHED_NORMAL (traditionally called SCHED_OTHER): The scheduling
|
||||||
|
policy that is used for regular tasks.
|
||||||
|
|
||||||
|
- SCHED_BATCH: Does not preempt nearly as often as regular tasks
|
||||||
|
would, thereby allowing tasks to run longer and make better use of
|
||||||
|
caches but at the cost of interactivity. This is well suited for
|
||||||
|
batch jobs.
|
||||||
|
|
||||||
|
- SCHED_IDLE: This is even weaker than nice 19, but its not a true
|
||||||
|
idle timer scheduler in order to avoid to get into priority
|
||||||
|
inversion problems which would deadlock the machine.
|
||||||
|
|
||||||
|
SCHED_FIFO/_RR are implemented in sched_rt.c and are as specified by
|
||||||
|
POSIX.
|
||||||
|
|
||||||
|
The command chrt from util-linux-ng 2.13.1.1 can set all of these except
|
||||||
|
SCHED_IDLE.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
6. SCHEDULING CLASSES
|
||||||
|
|
||||||
|
The new CFS scheduler has been designed in such a way to introduce "Scheduling
|
||||||
|
Classes," an extensible hierarchy of scheduler modules. These modules
|
||||||
|
encapsulate scheduling policy details and are handled by the scheduler core
|
||||||
|
without the core code assuming too much about them.
|
||||||
|
|
||||||
|
sched_fair.c implements the CFS scheduler described above.
|
||||||
|
|
||||||
|
sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler way than
|
||||||
|
the previous vanilla scheduler did. It uses 100 runqueues (for all 100 RT
|
||||||
|
priority levels, instead of 140 in the previous scheduler) and it needs no
|
||||||
|
expired array.
|
||||||
|
|
||||||
|
Scheduling classes are implemented through the sched_class structure, which
|
||||||
|
contains hooks to functions that must be called whenever an interesting event
|
||||||
|
occurs.
|
||||||
|
|
||||||
|
This is the (partial) list of the hooks:
|
||||||
|
|
||||||
|
- enqueue_task(...)
|
||||||
|
|
||||||
|
Called when a task enters a runnable state.
|
||||||
|
It puts the scheduling entity (task) into the red-black tree and
|
||||||
|
increments the nr_running variable.
|
||||||
|
|
||||||
|
- dequeue_tree(...)
|
||||||
|
|
||||||
|
When a task is no longer runnable, this function is called to keep the
|
||||||
|
corresponding scheduling entity out of the red-black tree. It decrements
|
||||||
|
the nr_running variable.
|
||||||
|
|
||||||
|
- yield_task(...)
|
||||||
|
|
||||||
|
This function is basically just a dequeue followed by an enqueue, unless the
|
||||||
|
compat_yield sysctl is turned on; in that case, it places the scheduling
|
||||||
|
entity at the right-most end of the red-black tree.
|
||||||
|
|
||||||
|
- check_preempt_curr(...)
|
||||||
|
|
||||||
|
This function checks if a task that entered the runnable state should
|
||||||
|
preempt the currently running task.
|
||||||
|
|
||||||
|
- pick_next_task(...)
|
||||||
|
|
||||||
|
This function chooses the most appropriate task eligible to run next.
|
||||||
|
|
||||||
|
- set_curr_task(...)
|
||||||
|
|
||||||
|
This function is called when a task changes its scheduling class or changes
|
||||||
|
its task group.
|
||||||
|
|
||||||
|
- task_tick(...)
|
||||||
|
|
||||||
|
This function is mostly called from time tick functions; it might lead to
|
||||||
|
process switch. This drives the running preemption.
|
||||||
|
|
||||||
|
- task_new(...)
|
||||||
|
|
||||||
|
The core scheduler gives the scheduling module an opportunity to manage new
|
||||||
|
task startup. The CFS scheduling module uses it for group scheduling, while
|
||||||
|
the scheduling module for a real-time task does not use it.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
7. GROUP SCHEDULER EXTENSIONS TO CFS
|
||||||
|
|
||||||
|
Normally, the scheduler operates on individual tasks and strives to provide
|
||||||
|
fair CPU time to each task. Sometimes, it may be desirable to group tasks and
|
||||||
|
provide fair CPU time to each such task group. For example, it may be
|
||||||
|
desirable to first provide fair CPU time to each user on the system and then to
|
||||||
|
each task belonging to a user.
|
||||||
|
|
||||||
|
CONFIG_GROUP_SCHED strives to achieve exactly that. It lets tasks to be
|
||||||
|
grouped and divides CPU time fairly among such groups.
|
||||||
|
|
||||||
|
CONFIG_RT_GROUP_SCHED permits to group real-time (i.e., SCHED_FIFO and
|
||||||
|
SCHED_RR) tasks.
|
||||||
|
|
||||||
|
CONFIG_FAIR_GROUP_SCHED permits to group CFS (i.e., SCHED_NORMAL and
|
||||||
|
SCHED_BATCH) tasks.
|
||||||
|
|
||||||
|
At present, there are two (mutually exclusive) mechanisms to group tasks for
|
||||||
|
CPU bandwidth control purposes:
|
||||||
|
|
||||||
|
- Based on user id (CONFIG_USER_SCHED)
|
||||||
|
|
||||||
|
With this option, tasks are grouped according to their user id.
|
||||||
|
|
||||||
|
- Based on "cgroup" pseudo filesystem (CONFIG_CGROUP_SCHED)
|
||||||
|
|
||||||
|
This options needs CONFIG_CGROUPS to be defined, and lets the administrator
|
||||||
|
create arbitrary groups of tasks, using the "cgroup" pseudo filesystem. See
|
||||||
|
Documentation/cgroups.txt for more information about this filesystem.
|
||||||
|
|
||||||
Only one of these options to group tasks can be chosen and not both.

Writing SBUS Drivers
|
|
||||||
|
|
||||||
David S. Miller (davem@redhat.com)
|
|
||||||
|
|
||||||
The SBUS driver interfaces of the Linux kernel have been
|
|
||||||
revamped completely for 2.4.x for several reasons. Foremost were
|
|
||||||
performance and complexity concerns. This document details these
|
|
||||||
new interfaces and how they are used to write an SBUS device driver.
|
|
||||||
|
|
||||||
SBUS drivers need to include <asm/sbus.h> to get access
|
|
||||||
to functions and structures described here.
|
|
||||||
|
|
||||||
Probing and Detection
|
|
||||||
|
|
||||||
Each SBUS device inside the machine is described by a
|
|
||||||
structure called "struct sbus_dev". Likewise, each SBUS bus
|
|
||||||
found in the system is described by a "struct sbus_bus". For
|
|
||||||
each SBUS bus, the devices underneath are hung in a tree-like
|
|
||||||
fashion off of the bus structure.
|
|
||||||
|
|
||||||
The SBUS device structure contains enough information
|
|
||||||
for you to implement your device probing algorithm and obtain
|
|
||||||
the bits necessary to run your device. The most commonly
|
|
||||||
used members of this structure, and their typical usage,
|
|
||||||
will be detailed below.
|
|
||||||
|
|
||||||
Here is a piece of skeleton code for performing a device
|
|
||||||
probe in an SBUS driver under Linux:
|
|
||||||
|
|
||||||
static int __devinit mydevice_probe_one(struct sbus_dev *sdev)
|
|
||||||
{
|
|
||||||
struct mysdevice *mp = kzalloc(sizeof(*mp), GFP_KERNEL);
|
|
||||||
|
|
||||||
if (!mp)
|
|
||||||
return -ENODEV;
|
|
||||||
|
|
||||||
...
|
|
||||||
dev_set_drvdata(&sdev->ofdev.dev, mp);
|
|
||||||
return 0;
|
|
||||||
...
|
|
||||||
}
|
|
||||||
|
|
||||||
static int __devinit mydevice_probe(struct of_device *dev,
|
|
||||||
const struct of_device_id *match)
|
|
||||||
{
|
|
||||||
struct sbus_dev *sdev = to_sbus_device(&dev->dev);
|
|
||||||
|
|
||||||
return mydevice_probe_one(sdev);
|
|
||||||
}
|
|
||||||
|
|
||||||
static int __devexit mydevice_remove(struct of_device *dev)
|
|
||||||
{
|
|
||||||
struct sbus_dev *sdev = to_sbus_device(&dev->dev);
|
|
||||||
struct mydevice *mp = dev_get_drvdata(&dev->dev);
|
|
||||||
|
|
||||||
return mydevice_remove_one(sdev, mp);
|
|
||||||
}
|
|
||||||
|
|
||||||
static struct of_device_id mydevice_match[] = {
|
|
||||||
{
|
|
||||||
.name = "mydevice",
|
|
||||||
},
|
|
||||||
{},
|
|
||||||
};
|
|
||||||
|
|
||||||
MODULE_DEVICE_TABLE(of, mydevice_match);
|
|
||||||
|
|
||||||
static struct of_platform_driver mydevice_driver = {
|
|
||||||
.match_table = mydevice_match,
|
|
||||||
.probe = mydevice_probe,
|
|
||||||
.remove = __devexit_p(mydevice_remove),
|
|
||||||
.driver = {
|
|
||||||
.name = "mydevice",
|
|
||||||
},
|
|
||||||
};
|
|
||||||
|
|
||||||
static int __init mydevice_init(void)
|
|
||||||
{
|
|
||||||
return of_register_driver(&mydevice_driver, &sbus_bus_type);
|
|
||||||
}
|
|
||||||
|
|
||||||
static void __exit mydevice_exit(void)
|
|
||||||
{
|
|
||||||
of_unregister_driver(&mydevice_driver);
|
|
||||||
}
|
|
||||||
|
|
||||||
module_init(mydevice_init);
|
|
||||||
module_exit(mydevice_exit);
|
|
||||||
|
|
||||||
The mydevice_match table is a series of entries which
|
|
||||||
describes what SBUS devices your driver is meant for. In the
|
|
||||||
simplest case you specify a string for the 'name' field. Every
|
|
||||||
SBUS device with a 'name' property matching your string will
|
|
||||||
be passed one-by-one to your .probe method.
|
|
||||||
|
|
||||||
You should store away your device private state structure
|
|
||||||
pointer in the drvdata area so that you can retrieve it later on
|
|
||||||
in your .remove method.
|
|
||||||
|
|
||||||
Any memory allocated, registers mapped, IRQs registered,
|
|
||||||
etc. must be undone by your .remove method so that all resources
|
|
||||||
of your device are released by the time it returns.
|
|
||||||
|
|
||||||
You should _NOT_ use the for_each_sbus(), for_each_sbusdev(),
|
|
||||||
and for_all_sbusdev() interfaces. They are deprecated, will be
|
|
||||||
removed, and no new driver should reference them ever.
|
|
||||||
|
|
||||||
Mapping and Accessing I/O Registers
|
|
||||||
|
|
||||||
Each SBUS device structure contains an array of descriptors
|
|
||||||
which describe each register set. We abuse struct resource for that.
|
|
||||||
They each correspond to the "reg" properties provided by the OBP firmware.
|
|
||||||
|
|
||||||
Before you can access your device's registers you must map
|
|
||||||
them. And later if you wish to shutdown your driver (for module
|
|
||||||
unload or similar) you must unmap them. You must treat them as
|
|
||||||
a resource, which you allocate (map) before using and free up
|
|
||||||
(unmap) when you are done with it.
|
|
||||||
|
|
||||||
The mapping information is stored in an opaque value
|
|
||||||
typed as an "unsigned long". This is the type of the return value
|
|
||||||
of the mapping interface, and the arguments to the unmapping
|
|
||||||
interface. Let's say you want to map the first set of registers.
|
|
||||||
Perhaps part of your driver software state structure looks like:
|
|
||||||
|
|
||||||
struct mydevice {
|
|
||||||
unsigned long control_regs;
|
|
||||||
...
|
|
||||||
struct sbus_dev *sdev;
|
|
||||||
...
|
|
||||||
};
|
|
||||||
|
|
||||||
At initialization time you then use the sbus_ioremap
|
|
||||||
interface to map in your registers, like so:
|
|
||||||
|
|
||||||
static void init_one_mydevice(struct sbus_dev *sdev)
|
|
||||||
{
|
|
||||||
struct mydevice *mp;
|
|
||||||
...
|
|
||||||
|
|
||||||
mp->control_regs = sbus_ioremap(&sdev->resource[0], 0,
|
|
||||||
CONTROL_REGS_SIZE, "mydevice regs");
|
|
||||||
if (!mp->control_regs) {
|
|
||||||
/* Failure, cleanup and return. */
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
Second argument to sbus_ioremap is an offset for
|
|
||||||
cranky devices with broken OBP PROM. The sbus_ioremap uses only
|
|
||||||
a start address and flags from the resource structure.
|
|
||||||
Therefore it is possible to use the same resource to map
|
|
||||||
several sets of registers or even to fabricate a resource
|
|
||||||
structure if driver gets physical address from some private place.
|
|
||||||
This practice is discouraged though. Use whatever OBP PROM
|
|
||||||
provided to you.
|
|
||||||
|
|
||||||
And here is how you might unmap these registers later at
|
|
||||||
driver shutdown or module unload time, using the sbus_iounmap
|
|
||||||
interface:
|
|
||||||
|
|
||||||
static void mydevice_unmap_regs(struct mydevice *mp)
|
|
||||||
{
|
|
||||||
sbus_iounmap(mp->control_regs, CONTROL_REGS_SIZE);
|
|
||||||
}
|
|
||||||
|
|
||||||
Finally, to actually access your registers there are 6
|
|
||||||
interface routines at your disposal. Accesses are byte (8 bit),
|
|
||||||
word (16 bit), or longword (32 bit) sized. Here they are:
|
|
||||||
|
|
||||||
u8 sbus_readb(unsigned long reg) /* read byte */
|
|
||||||
u16 sbus_readw(unsigned long reg) /* read word */
|

So, let's say your device has a control register of some sort
|
|
||||||
at offset zero. The following might implement resetting your device:
|
|
||||||
|
|
||||||
#define CONTROL 0x00UL
|
|
||||||
|
|
||||||
#define CONTROL_RESET 0x00000001 /* Reset hardware */
|
|
||||||
|
|
||||||
static void mydevice_reset(struct mydevice *mp)
|
|
||||||
{
|
|
||||||
sbus_writel(CONTROL_RESET, mp->regs + CONTROL);
|
|
||||||
}
|
|
||||||
|
|
||||||
Or perhaps there is a data port register at an offset of
|
|
||||||
16 bytes which allows you to read bytes from a fifo in the device:
|
|
||||||
|
|
||||||
#define DATA 0x10UL
|
|
||||||
|
|
||||||
static u8 mydevice_get_byte(struct mydevice *mp)
|
|
||||||
{
|
|
||||||
return sbus_readb(mp->regs + DATA);
|
|
||||||
}
|
|
||||||
|
|
||||||
It's pretty straightforward, and clueful readers may have
|
|
||||||
noticed that these interfaces mimick the PCI interfaces of the
|
|
||||||
Linux kernel. This was not by accident.
|
|
||||||
|
|
||||||
WARNING:
|
|
||||||
|
|
||||||
DO NOT try to treat these opaque register mapping
|
|
||||||
values as a memory mapped pointer to some structure
|
|
||||||
which you can dereference.
|
|
||||||
|
|
||||||
It may be memory mapped, it may not be. In fact it
|
|
||||||
could be a physical address, or it could be the time
|
|
||||||
of day xor'd with 0xdeadbeef. :-)
|
|
||||||
|
|
||||||
Whatever it is, it's an implementation detail. The
|
|
||||||
interface was done this way to shield the driver
|
|
||||||
author from such complexities.
|
|
||||||
|
|
||||||
Doing DVMA
|
|
||||||
|
|
||||||
SBUS devices can perform DMA transactions in a way similar
|
|
||||||
to PCI but dissimilar to ISA, e.g. DMA masters supply address.
|
|
||||||
In contrast to PCI, however, that address (a bus address) is
|
|
||||||
translated by IOMMU before a memory access is performed and therefore
|
|
||||||
it is virtual. Sun calls this procedure DVMA.
|
|
||||||
|
|
||||||
Linux supports two styles of using SBUS DVMA: "consistent memory"
|
|
||||||
and "streaming DVMA". CPU view of consistent memory chunk is, well,
|
|
||||||
consistent with a view of a device. Think of it as an uncached memory.
|
|
||||||
Typically this way of doing DVMA is not very fast and drivers use it
|
|
||||||
mostly for control blocks or queues. On some CPUs we cannot flush or
|
|
||||||
invalidate individual pages or cache lines and doing explicit flushing
|
|
||||||
over ever little byte in every control block would be wasteful.
|
|
||||||
|
|
||||||
Streaming DVMA is a preferred way to transfer large amounts of data.
|
|
||||||
This process works in the following way:
|
|
||||||
1. a CPU stops accessing a certain part of memory,
|
|
||||||
flushes its caches covering that memory;
|
|
||||||
2. a device does DVMA accesses, then posts an interrupt;
|
|
||||||
3. CPU invalidates its caches and starts to access the memory.
|
|
||||||
|
|
||||||
A single streaming DVMA operation can touch several discontiguous
|
|
||||||
regions of a virtual bus address space. This is called a scatter-gather
|
|
||||||
DVMA.
|
|
||||||
|
|
||||||
[TBD: Why do not we neither Solaris attempt to map disjoint pages
|
|
||||||
into a single virtual chunk with the help of IOMMU, so that non SG
|
|
||||||
DVMA masters would do SG? It'd be very helpful for RAID.]
|
|
||||||
|
|
||||||
In order to perform a consistent DVMA a driver does something
|
|
||||||
like the following:
|
|
||||||
|
|
||||||
char *mem; /* Address in the CPU space */
|
|
||||||
u32 busa; /* Address in the SBus space */
|
|
||||||
|
|
||||||
mem = (char *) sbus_alloc_consistent(sdev, MYMEMSIZE, &busa);
|
|
||||||
|
|
||||||
Then mem is used when CPU accesses this memory and u32
|
|
||||||
is fed to the device so that it can do DVMA. This is typically
|
|
||||||
done with an sbus_writel() into some device register.
|
|
||||||
|
|
||||||
Do not forget to free the DVMA resources once you are done:
|
|
||||||
|
|
||||||
sbus_free_consistent(sdev, MYMEMSIZE, mem, busa);
|
|
||||||
|
|
||||||
Streaming DVMA is more interesting. First you allocate some
|
|
||||||
memory suitable for it or pin down some user pages. Then it all works
|
|
||||||
like this:
|
|
||||||
|
|
||||||
char *mem = argumen1;
|
|
||||||
unsigned int size = argument2;
|
|
||||||
u32 busa; /* Address in the SBus space */
|
|
||||||
|
|
||||||
*mem = 1; /* CPU can access */
|
|
||||||
busa = sbus_map_single(sdev, mem, size);
|
|
||||||
if (busa == 0) .......
|
|
||||||
|
|
||||||
/* Tell the device to use busa here */
|
|
||||||
/* CPU cannot access the memory without sbus_dma_sync_single() */
|
|
||||||
|
|
||||||
sbus_unmap_single(sdev, busa, size);
|
|
||||||
if (*mem == 0) .... /* CPU can access again */
|
|
||||||
|
|
||||||
It is possible to retain mappings and ask the device to
|
|
||||||
access data again and again without calling sbus_unmap_single.
|
|
||||||
However, CPU caches must be invalidated with sbus_dma_sync_single
|
|
||||||
before such access.
|
|
||||||
|
|
||||||
[TBD but what about writeback caches here... do we have any?]
|
|
||||||
|
|
||||||
There is an equivalent set of functions doing the same thing
|
|
||||||
only with several memory segments at once for devices capable of
|
|
||||||
scatter-gather transfers. Use the Source, Luke.
|
|
||||||
|
|
||||||
Examples
|
|
||||||
|
|
||||||
drivers/net/sunhme.c
|
|
||||||
This is a complicated driver which illustrates many concepts
|
|
||||||
discussed above and plus it handles both PCI and SBUS boards.
|
|
||||||
|
|
||||||
drivers/scsi/esp.c
|
|
||||||
Check it out for scatter-gather DVMA.

|
|
||||||
A non-DVMA device.
|
|
||||||
|
|
||||||
drivers/net/sunlance.c
|
|
||||||
Lance driver abuses consistent mappings for data transfer.
|
|
||||||
It is a nifty trick which we do not particularly recommend...
|
|
||||||
Just check it out and know that it's legal.

High Precision Event Timer Driver for Linux

The High Precision Event Timer (HPET) hardware is the future replacement
|
The High Precision Event Timer (HPET) hardware follows a specification
|
||||||
for the 8254 and Real Time Clock (RTC) periodic timer functionality.
|
by Intel and Microsoft which can be found at
|
||||||
Each HPET can have up to 32 timers. It is possible to configure the
|
|
||||||
first two timers as legacy replacements for 8254 and RTC periodic timers.
|
http://www.intel.com/technology/architecture/hpetspec.htm
|
||||||
A specification done by Intel and Microsoft can be found at
|
|
||||||
<http://www.intel.com/technology/architecture/hpetspec.htm>.
|
Each HPET has one fixed-rate counter (at 10+ MHz, hence "High Precision")
|
||||||
|
and up to 32 comparators. Normally three or more comparators are provided,
|
||||||
|
each of which can generate oneshot interupts and at least one of which has
|
||||||
|
additional hardware to support periodic interrupts. The comparators are
|
||||||
|
also called "timers", which can be misleading since usually timers are
|
||||||
|
independent of each other ... these share a counter, complicating resets.
|
||||||
|
|
||||||
|
HPET devices can support two interrupt routing modes. In one mode, the
|
||||||
|
comparators are additional interrupt sources with no particular system
|
||||||
|
role. Many x86 BIOS writers don't route HPET interrupts at all, which
|
||||||
|
prevents use of that mode. They support the other "legacy replacement"
|
||||||
|
mode where the first two comparators block interrupts from 8254 timers
|
||||||
|
and from the RTC.
|
||||||
|

The kernel API has three interfaces exported from the driver:
|
|

|
|

hpet_register(struct hpet_task *tp, int periodic)
|
|

hpet_unregister(struct hpet_task *tp)

hpet_control(struct hpet_task *tp, unsigned int cmd, unsigned long arg)
|
|

|
|
||||||
The kernel module using this interface fills in the ht_func and ht_data
|
|
||||||
members of the hpet_task structure before calling hpet_register.
|
|
||||||
hpet_control simply vectors to the hpet_ioctl routine and has the same
|
|
||||||
commands and respective arguments as the user API. hpet_unregister
|
|
||||||
is used to terminate usage of the HPET timer reserved by hpet_register.

This document describes the ALi m5602 bridge connected
|

|
to the following supported sensors:
|

|
OmniVision OV9650,
|
||||||
|
Samsung s5k83a,
|
||||||
|
Samsung s5k4aa,
|
||||||
|
Micron mt9m111,
|
||||||
|
Pixel plus PO1030
|
||||||
|
|
||||||
|
This driver mimics the windows drivers, which have a braindead implementation sending bayer-encoded frames at VGA resolution.
|
||||||
|
In a perfect world we should be able to reprogram the m5602 and the connected sensor in hardware instead, supporting a range of resolutions and pixelformats
|
||||||
|
|

|
Anyway, have fun and please report any bugs to m560x-driver-devel@lists.sourceforge.net

Soc-Camera Subsystem
|
||||||
|
====================
|
||||||
|
|
||||||
|
Terminology
|
||||||
|
-----------
|
||||||
|
|
||||||
|
The following terms are used in this document:
|
||||||
|
- camera / camera device / camera sensor - a video-camera sensor chip, capable
|
||||||
|
of connecting to a variety of systems and interfaces, typically uses i2c for
|
||||||
|
control and configuration, and a parallel or a serial bus for data.
|
||||||
|
- camera host - an interface, to which a camera is connected. Typically a
|
||||||
|
specialised interface, present on many SoCs, e.g., PXA27x and PXA3xx, SuperH,
|
||||||
|
AVR32, i.MX27, i.MX31.
|
||||||
|
- camera host bus - a connection between a camera host and a camera. Can be
|
||||||
|
parallel or serial, consists of data and control lines, e.g., clock, vertical
|
||||||
|
and horizontal synchronization signals.
|
||||||
|
|
||||||
|
Purpose of the soc-camera subsystem
|
||||||
|
-----------------------------------
|
||||||
|
|
||||||
|
The soc-camera subsystem provides a unified API between camera host drivers and
|
||||||
|
camera sensor drivers. It implements a V4L2 interface to the user, currently
|
||||||
|
only the mmap method is supported.
|
||||||
|
|
||||||
|
This subsystem has been written to connect drivers for System-on-Chip (SoC)
|
||||||
|
video capture interfaces with drivers for CMOS camera sensor chips to enable
|
||||||
|
the reuse of sensor drivers with various hosts. The subsystem has been designed
|
||||||
|
to support multiple camera host interfaces and multiple cameras per interface,
|
||||||
|
although most applications have only one camera sensor.
|
||||||
|
|
||||||
|
Existing drivers
|
||||||
|
----------------
|
||||||
|
|
||||||
|
As of 2.6.27-rc4 there are two host drivers in the mainline: pxa_camera.c for
|
||||||
|
PXA27x SoCs and sh_mobile_ceu_camera.c for SuperH SoCs, and four sensor drivers:
|
||||||
|
mt9m001.c, mt9m111.c, mt9v022.c and a generic soc_camera_platform.c driver. This
|
||||||
|
list is not supposed to be updated, look for more examples in your tree.
|
||||||
|
|
||||||
|
Camera host API
|
||||||
|
---------------
|
||||||
|
|
||||||
|
A host camera driver is registered using the
|
||||||
|
|
||||||
|
soc_camera_host_register(struct soc_camera_host *);
|
||||||
|
|
||||||
|
function. The host object can be initialized as follows:
|
||||||
|
|
||||||
|
static struct soc_camera_host pxa_soc_camera_host = {
|
||||||
|
.drv_name = PXA_CAM_DRV_NAME,
|
||||||
|
.ops = &pxa_soc_camera_host_ops,
|
||||||
|
};
|
||||||
|
|
||||||
|
All camera host methods are passed in a struct soc_camera_host_ops:
|
||||||
|
|
||||||
|
static struct soc_camera_host_ops pxa_soc_camera_host_ops = {
|
||||||
|
.owner = THIS_MODULE,
|
||||||
|
.add = pxa_camera_add_device,
|
||||||
|
.remove = pxa_camera_remove_device,
|
||||||
|
.suspend = pxa_camera_suspend,
|
||||||
|
.resume = pxa_camera_resume,
|
||||||
|
.set_fmt_cap = pxa_camera_set_fmt_cap,
|
||||||
|
.try_fmt_cap = pxa_camera_try_fmt_cap,
|
||||||
|
.init_videobuf = pxa_camera_init_videobuf,
|
||||||
|
.reqbufs = pxa_camera_reqbufs,
|
||||||
|
.poll = pxa_camera_poll,
|
||||||
|
.querycap = pxa_camera_querycap,
|
||||||
|
.try_bus_param = pxa_camera_try_bus_param,
|
||||||
|
.set_bus_param = pxa_camera_set_bus_param,
|
||||||
|
};
|
||||||
|
|
||||||
|
.add and .remove methods are called when a sensor is attached to or detached
|
||||||
|
from the host, apart from performing host-internal tasks they shall also call
|
||||||
|
sensor driver's .init and .release methods respectively. .suspend and .resume
|
||||||
|
methods implement host's power-management functionality and its their
|
||||||
|
responsibility to call respective sensor's methods. .try_bus_param and
|
||||||
|
.set_bus_param are used to negotiate physical connection parameters between the
|
||||||
|
host and the sensor. .init_videobuf is called by soc-camera core when a
|
||||||
|
video-device is opened, further video-buffer management is implemented completely
|
||||||
|
by the specific camera host driver. The rest of the methods are called from
|
||||||
|
respective V4L2 operations.
|
||||||
|
|
||||||
|
Camera API
|
||||||
|
----------
|
||||||
|
|
||||||
|
Sensor drivers can use struct soc_camera_link, typically provided by the
|
||||||
|
platform, and used to specify to which camera host bus the sensor is connected,
|
||||||
|
and arbitrarily provide platform .power and .reset methods for the camera.
|
||||||
|
soc_camera_device_register() and soc_camera_device_unregister() functions are
|
||||||
|
used to add a sensor driver to or remove one from the system. The registration
|
||||||
|
function takes a pointer to struct soc_camera_device as the only parameter.
|
||||||
|
This struct can be initialized as follows:
|
||||||
|
|
||||||
|
/* link to driver operations */
|
||||||
|
icd->ops = &mt9m001_ops;
|
||||||
|
/* link to the underlying physical (e.g., i2c) device */
|
||||||
|
icd->control = &client->dev;
|
||||||
|
/* window geometry */
|
||||||
|
icd->x_min = 20;
|
||||||
|
icd->y_min = 12;
|
||||||
|
icd->x_current = 20;
|
||||||
|
icd->y_current = 12;
|
||||||
|
icd->width_min = 48;
|
||||||
|
icd->width_max = 1280;
|
||||||
|
icd->height_min = 32;
|
||||||
|
icd->height_max = 1024;
|
||||||
|
icd->y_skip_top = 1;
|
||||||
|
/* camera bus ID, typically obtained from platform data */
|
||||||
|
icd->iface = icl->bus_id;
|
||||||
|
|
||||||
|
struct soc_camera_ops provides .probe and .remove methods, which are called by
|
||||||
|
the soc-camera core, when a camera is matched against or removed from a camera
|
||||||
|
host bus, .init, .release, .suspend, and .resume are called from the camera host
|
||||||
|
driver as discussed above. Other members of this struct provide respective V4L2
|
||||||
|
functionality.
|
||||||
|
|
||||||
|
struct soc_camera_device also links to an array of struct soc_camera_data_format,
|
||||||
|
listing pixel formats, supported by the camera.
