|
||||
1. Overview
|
||||
|
||||
Mflash and gflash are embedded flash drive. The only difference is mflash is
|
||||
MCP(Multi Chip Package) device. These two device operate exactly same way.
|
||||
So the rest mflash repersents mflash and gflash altogether.
|
||||
|
||||
Internally, mflash has nand flash and other hardware logics and supports
|
||||
2 different operation (ATA, IO) modes. ATA mode doesn't need any new
|
||||
driver and currently works well under standard IDE subsystem. Actually it's
|
||||
one chip SSD. IO mode is ATA-like custom mode for the host that doesn't have
|
||||
IDE interface.
|
||||
|
||||
Followings are brief descriptions about IO mode.
|
||||
A. IO mode based on ATA protocol and uses some custom command. (read confirm,
|
||||
write confirm)
|
||||
B. IO mode uses SRAM bus interface.
|
||||
C. IO mode supports 4kB boot area, so host can boot from mflash.
|
||||
|
||||
2. Reserved area configuration
|
||||
If host boot from mflash, usually needs raw area for boot loader image. All of
|
||||
the mflash's block device operation will be taken this value as start offset.
|
||||
Note that boot loader's size of reserved area and kernel configuration value
|
||||
must be same.
|
||||
|
||||
3. Example of mflash platform driver registration

||||

cpuacct controller uses percpu_counter interface to collect user and

system times. This has two side effects:
|
||||
|
||||
- It is theoretically possible to see wrong values for user and system times.
|
||||
This is because percpu_counter_read() on 32bit systems isn't safe
|
||||
against concurrent writes.
|
||||
- It is possible to see slightly outdated values for user and system times

due to the batch processing nature of percpu_counter.

Kernel NFS Server Statistics
|
||||
============================
|
||||
|
||||
This document describes the format and semantics of the statistics
|
||||
which the kernel NFS server makes available to userspace. These
|
||||
statistics are available in several text form pseudo files, each of
|
||||
which is described separately below.
|
||||
|
||||
In most cases you don't need to know these formats, as the nfsstat(8)
|
||||
program from the nfs-utils distribution provides a helpful command-line
|
||||
interface for extracting and printing them.
|
||||
|
||||
All the files described here are formatted as a sequence of text lines,
|
||||
separated by newline '\n' characters. Lines beginning with a hash
|
||||
'#' character are comments intended for humans and should be ignored
|
||||
by parsing routines. All other lines contain a sequence of fields
|
||||
separated by whitespace.
|
||||
|
||||
/proc/fs/nfsd/pool_stats
|
||||
------------------------
|
||||
|
||||
This file is available in kernels from 2.6.30 onwards, if the
|
||||
/proc/fs/nfsd filesystem is mounted (it almost always should be).
|
||||
|
||||
The first line is a comment which describes the fields present in
|
||||
all the other lines. The other lines present the following data as
|
||||
a sequence of unsigned decimal numeric fields. One line is shown
|
||||
for each NFS thread pool.
|
||||
|
||||
All counters are 64 bits wide and wrap naturally. There is no way
|
||||
to zero these counters, instead applications should do their own
|
||||
rate conversion.
|
||||
|
||||
pool
|
||||
The id number of the NFS thread pool to which this line applies.
|
||||
This number does not change.
|
||||
|
||||
Thread pool ids are a contiguous set of small integers starting
|
||||
at zero. The maximum value depends on the thread pool mode, but
|
||||
currently cannot be larger than the number of CPUs in the system.
|
||||
Note that in the default case there will be a single thread pool
|
||||
which contains all the nfsd threads and all the CPUs in the system,
|
||||
and thus this file will have a single line with a pool id of "0".
|
||||
|
||||
packets-arrived
|
||||
Counts how many NFS packets have arrived. More precisely, this
|
||||
is the number of times that the network stack has notified the
|
||||
sunrpc server layer that new data may be available on a transport
|
||||
(e.g. an NFS or UDP socket or an NFS/RDMA endpoint).
|
||||
|
||||
Depending on the NFS workload patterns and various network stack
|
||||
effects (such as Large Receive Offload) which can combine packets
|
||||
on the wire, this may be either more or less than the number
|
||||
of NFS calls received (which statistic is available elsewhere).
|
||||
However this is a more accurate and less workload-dependent measure
|
||||
of how much CPU load is being placed on the sunrpc server layer
|
||||
due to NFS network traffic.
|
||||
|
||||
sockets-enqueued
|
||||
Counts how many times an NFS transport is enqueued to wait for
|
||||
an nfsd thread to service it, i.e. no nfsd thread was considered
|
||||
available.
|
||||
|
||||
The circumstance this statistic tracks indicates that there was NFS
|
||||
network-facing work to be done but it couldn't be done immediately,
|
||||
thus introducing a small delay in servicing NFS calls. The ideal
|
||||
rate of change for this counter is zero; significantly non-zero
|
||||
values may indicate a performance limitation.
|
||||
|
||||
This can happen either because there are too few nfsd threads in the
|
||||
thread pool for the NFS workload (the workload is thread-limited),
|
||||
or because the NFS workload needs more CPU time than is available in
|
||||
the thread pool (the workload is CPU-limited). In the former case,
|
||||
configuring more nfsd threads will probably improve the performance
|
||||
of the NFS workload. In the latter case, the sunrpc server layer is
|
||||
already choosing not to wake idle nfsd threads because there are too
|
||||
many nfsd threads which want to run but cannot, so configuring more
|
||||
nfsd threads will make no difference whatsoever. The overloads-avoided
|
||||
statistic (see below) can be used to distinguish these cases.
|
||||
|
||||
threads-woken
|
||||
Counts how many times an idle nfsd thread is woken to try to
|
||||
receive some data from an NFS transport.
|
||||
|
||||
This statistic tracks the circumstance where incoming
|
||||
network-facing NFS work is being handled quickly, which is a good
|
||||
thing. The ideal rate of change for this counter will be close
|
||||
to but less than the rate of change of the packets-arrived counter.
|
||||
|
||||
overloads-avoided
|
||||
Counts how many times the sunrpc server layer chose not to wake an
|
||||
nfsd thread, despite the presence of idle nfsd threads, because
|
||||
too many nfsd threads had been recently woken but could not get
|
||||
enough CPU time to actually run.
|
||||
|
||||
This statistic counts a circumstance where the sunrpc layer
|
||||
heuristically avoids overloading the CPU scheduler with too many
|
||||
runnable nfsd threads. The ideal rate of change for this counter
|
||||
is zero. Significant non-zero values indicate that the workload
|
||||
is CPU limited. Usually this is associated with heavy CPU usage
|
||||
on all the CPUs in the nfsd thread pool.
|
||||
|
||||
If a sustained large overloads-avoided rate is detected on a pool,
|
||||
the top(1) utility should be used to check for the following
|
||||
pattern of CPU usage on all the CPUs associated with the given
|
||||
nfsd thread pool.
|
||||
|
||||
- %us ~= 0 (as you're *NOT* running applications on your NFS server)
|
||||
|
||||
- %wa ~= 0
|
||||
|
||||
- %id ~= 0
|
||||
|
||||
- %sy + %hi + %si ~= 100
|
||||
|
||||
If this pattern is seen, configuring more nfsd threads will *not*
|
||||
improve the performance of the workload. If this patten is not
|
||||
seen, then something more subtle is wrong.
|
||||
|
||||
threads-timedout
|
||||
Counts how many times an nfsd thread triggered an idle timeout,
|
||||
i.e. was not woken to handle any incoming network packets for
|
||||
some time.
|
||||
|
||||
This statistic counts a circumstance where there are more nfsd
|
||||
threads configured than can be used by the NFS workload. This is
|
||||
a clue that the number of nfsd threads can be reduced without
|
||||
affecting performance. Unfortunately, it's only a clue and not
|
||||
a strong indication, for a couple of reasons:
|
||||
|
||||
- Currently the rate at which the counter is incremented is quite
|
||||
slow; the idle timeout is 60 minutes. Unless the NFS workload
|
||||
remains constant for hours at a time, this counter is unlikely
|
||||
to be providing information that is still useful.
|
||||
|
||||
- It is usually a wise policy to provide some slack,
|
||||
i.e. configure a few more nfsds than are currently needed,
|
||||
to allow for future spikes in load.
|
||||
|
||||
|
||||
Note that incoming packets on NFS transports will be dealt with in
|
||||
one of three ways. An nfsd thread can be woken (threads-woken counts
|
||||
this case), or the transport can be enqueued for later attention
|
||||
(sockets-enqueued counts this case), or the packet can be temporarily
|
||||
deferred because the transport is currently being used by an nfsd
|
||||
thread. This last case is not very interesting and is not explicitly
|
||||
counted, but can be inferred from the other counters thus:
|
||||
|
||||
packets-deferred = packets-arrived - ( sockets-enqueued + threads-woken )

NFSv4.1 Server Implementation
|
||||
|
||||
Server support for minorversion 1 can be controlled using the
|
||||
/proc/fs/nfsd/versions control file. The string output returned
|
||||
by reading this file will contain either "+4.1" or "-4.1"
|
||||
correspondingly.
|
||||
|
||||
Currently, server support for minorversion 1 is disabled by default.
|
||||
It can be enabled at run time by writing the string "+4.1" to
|
||||
the /proc/fs/nfsd/versions control file. Note that to write this
|
||||
control file, the nfsd service must be taken down. Use your user-mode
|
||||
nfs-utils to set this up; see rpc.nfsd(8)
|
||||
|
||||
The NFSv4 minorversion 1 (NFSv4.1) implementation in nfsd is based
|
||||
on the latest NFSv4.1 Internet Draft:
|
||||
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-29
|
||||
|
||||
From the many new features in NFSv4.1 the current implementation
|
||||
focuses on the mandatory-to-implement NFSv4.1 Sessions, providing
|
||||
"exactly once" semantics and better control and throttling of the
|
||||
resources allocated for each client.
|
||||
|
||||
Other NFSv4.1 features, Parallel NFS operations in particular,
|
||||
are still under development out of tree.
|
||||
See http://wiki.linux-nfs.org/wiki/index.php/PNFS_prototype_design
|
||||
for more information.
|
||||
|
||||
The table below, taken from the NFSv4.1 document, lists
|
||||
the operations that are mandatory to implement (REQ), optional
|
||||
(OPT), and NFSv4.0 operations that are required not to implement (MNI)
|
||||
in minor version 1. The first column indicates the operations that
|
||||
are not supported yet by the linux server implementation.
|
||||
|
||||

NILFS2
|
||||
------
|
||||
|
||||
NILFS2 is a log-structured file system (LFS) supporting continuous
|
||||
snapshotting. In addition to versioning capability of the entire file
|
||||
system, users can even restore files mistakenly overwritten or
|
||||
destroyed just a few seconds ago. Since NILFS2 can keep consistency
|
||||
like conventional LFS, it achieves quick recovery after system
|
||||
crashes.
|
||||
|
||||
NILFS2 creates a number of checkpoints every few seconds or per
|
||||
synchronous write basis (unless there is no change). Users can select
|
||||
significant versions among continuously created checkpoints, and can
|
||||
change them into snapshots which will be preserved until they are
|
||||
changed back to checkpoints.
|
||||
|
||||
There is no limit on the number of snapshots until the volume gets
|
||||
full. Each snapshot is mountable as a read-only file system
|
||||
concurrently with its writable mount, and this feature is convenient
|
||||
for online backup.
|
||||
|
||||
The userland tools are included in nilfs-utils package, which is
|
||||
available from the following download page. At least "mkfs.nilfs2",
|
||||
"mount.nilfs2", "umount.nilfs2", and "nilfs_cleanerd" (so called
|
||||
cleaner or garbage collector) are required. Details on the tools are
|
||||
described in the man pages included in the package.

system after a crash.

NILFS2 usage
|
||||
============
|
||||
|
||||
To use nilfs2 as a local file system, simply:
|
||||
|
||||
# mkfs -t nilfs2 /dev/block_device
|
||||
# mount -t nilfs2 /dev/block_device /dir
|
||||
|
||||
This will also invoke the cleaner through the mount helper program
|
||||
(mount.nilfs2).
|
||||
|
||||
Checkpoints and snapshots are managed by the following commands.
|
||||
Their manpages are included in the nilfs-utils package above.
|
||||
|
||||
lscp list checkpoints or snapshots.
|
||||
mkcp make a checkpoint or a snapshot.
|
||||
chcp change an existing checkpoint to a snapshot or vice versa.
|
||||
rmcp invalidate specified checkpoint(s).
|
||||
|
||||
To mount a snapshot,
|
||||
|
||||
# mount -t nilfs2 -r -o cp=<cno> /dev/block_device /snap_dir
|
||||
|
||||
where <cno> is the checkpoint number of the snapshot.
|
||||
|
||||
To unmount the NILFS2 mount point or snapshot, simply:
|
||||
|
||||
# umount /dir
|
||||
|
||||
Then, the cleaner daemon is automatically shut down by the umount
|
||||
helper program (umount.nilfs2).
|
||||
|
||||
Disk format
|
||||
===========
|
||||
|
||||
A nilfs2 volume is equally divided into a number of segments except
|
||||
for the super block (SB) and segment #0. A segment is the container
|
||||
of logs. Each log is composed of summary information blocks, payload
|
||||
blocks, and an optional super root block (SR):
|
||||
|
||||
______________________________________________________
|
||||

||||

|
||||
.______________________________.
|
||||
| Summary | Payload blocks |SR|
|
||||
|_blocks__|_________________|__|
|
||||
|
||||
The payload blocks are organized per file, and each file consists of
|
||||
data blocks and B-tree node blocks:
|
||||
|
||||
|<--- File-A --->|<--- File-B --->|
|
||||
_______________________________________________________________
|
||||
| Data blocks | B-tree blocks | Data blocks | B-tree blocks | ...
|
||||
_|_____________|_______________|_____________|_______________|_
|
||||
|
||||
|
||||
Since only the modified blocks are written in the log, it may have
|
||||
files without data blocks or B-tree node blocks.
|
||||
|
||||
The organization of the blocks is recorded in the summary information
|
||||
blocks, which contains a header structure (nilfs_segment_summary), per
|
||||
file structures (nilfs_finfo), and per block structures (nilfs_binfo):
|
||||
|
||||
_________________________________________________________________________
|
||||

||||
|_blocks__|___A___|_(A,1)_|_____|(A,Na)_|___B___|_(B,1)_|_____|(B,Nb)_|___
|
||||
|
||||
|
||||
The logs include regular files, directory files, symbolic link files
|
||||
and several meta data files. The mata data files are the files used
|
||||
to maintain file system meta data. The current version of NILFS2 uses
|
||||
the following meta data files:
|
||||
|
||||
1) Inode file (ifile) -- Stores on-disk inodes
|
||||
2) Checkpoint file (cpfile) -- Stores checkpoints
|
||||
3) Segment usage file (sufile) -- Stores allocation state of segments
|
||||
4) Data address translation file -- Maps virtual block numbers to usual
|
||||
(DAT) block numbers. This file serves to
|
||||
make on-disk blocks relocatable.
|
||||
|
||||
The following figure shows a typical organization of the logs:
|
||||
|
||||
_________________________________________________________________________
|
||||
| Summary | regular file | file | ... | ifile | cpfile | sufile | DAT |SR|
|
||||
|_blocks__|_or_directory_|_______|_____|_______|________|________|_____|__|
|
||||
|
||||
|
||||
To stride over segment boundaries, this sequence of files may be split
|
||||
into multiple logs. The sequence of logs that should be treated as
|
||||
logically one log, is delimited with flags marked in the segment
|
||||
summary. The recovery code of nilfs2 looks this boundary information
|
||||
to ensure atomicity of updates.
|
||||
|
||||
The super root block is inserted for every checkpoints. It includes
|
||||
three special inodes, inodes for the DAT, cpfile, and sufile. Inodes
|
||||
of regular files, directories, symlinks and other special files, are
|
||||
included in the ifile. The inode of ifile itself is included in the
|
||||
corresponding checkpoint entry in the cpfile. Thus, the hierarchy
|
||||
among NILFS2 files can be depicted as follows:
|
||||
|
||||
Super block (SB)
|
||||
|
|
||||
v
|

Description
|
||||
-----------
|
||||
|
||||
The GMT G760A Fan Speed PWM Controller is connected directly to a fan
|
||||
and performs closed-loop control of the fan speed.
|
||||
|
||||
The fan speed is programmed by setting the period via 'pwm1' of two
|
||||
consecutive speed pulses. The period is defined in terms of clock
|
||||
cycle counts of an assumed 32kHz clock source.
|
||||
|
||||
Setting a period of 0 stops the fan; setting the period to 255 sets
|
||||
fan to maximum speed.
|
||||
|
||||
The measured fan rotation speed returned via 'fan1_input' is derived
|
||||
from the measured speed pulse period by assuming again a 32kHz clock
|
||||
source and a 2 pulse-per-revolution fan.
|
||||
|
||||
The 'alarms' file provides access to the two alarm bits provided by
|
||||
the G760A chip's status register: Bit 0 is set when the actual fan
|
||||
speed differs more than 20% with respect to the programmed fan speed;
|
||||
bit 1 is set when fan speed is below 1920 RPM.
|
||||
|
||||
The g760a driver will not update its values more frequently than every
|
||||
other second; reading them more often will do no harm, but will return
|
||||
'old' values.

The P_Key for any interface is given by the "pkey" file, and the

|
||||
|
||||
Datagram vs Connected modes
|
||||
|
||||
The IPoIB driver supports two modes of operation: datagram and
|
||||
connected. The mode is set and read through an interface's
|
||||
/sys/class/net/<intf name>/mode file.
|
||||
|
||||
In datagram mode, the IB UD (Unreliable Datagram) transport is used
|
||||
and so the interface MTU has is equal to the IB L2 MTU minus the
|
||||
IPoIB encapsulation header (4 bytes). For example, in a typical IB
|
||||
fabric with a 2K MTU, the IPoIB MTU will be 2048 - 4 = 2044 bytes.
|
||||
|
||||
In connected mode, the IB RC (Reliable Connected) transport is used.
|
||||
Connected mode is to takes advantage of the connected nature of the
|
||||
IB transport and allows an MTU up to the maximal IP packet size of
|
||||
64K, which reduces the number of IP packets needed for handling
|
||||
large UDP datagrams, TCP segments, etc and increases the performance
|
||||
for large messages.
|
||||
|
||||
In connected mode, the interface's UD QP is still used for multicast
|
||||
and communication with peers that don't support connected mode. In
|
||||
this case, RX emulation of ICMP PMTU packets is used to cause the
|
||||
networking stack to use the smaller UD MTU for these neighbours.
|
||||
|
||||
Stateless offloads
|
||||
|
||||
If the IB HW supports IPoIB stateless offloads, IPoIB advertises
|
||||
TCP/IP checksum and/or Large Send (LSO) offloading capability to the
|
||||
network stack.
|
||||
|
||||
Large Receive (LRO) offloading is also implemented and may be turned
|
||||
on/off using ethtool calls. Currently LRO is supported only for
|
||||
checksum offload capable devices.
|
||||
|
||||
Stateless offloads are supported only in datagram mode.
|
||||
|
||||
Interrupt moderation
|
||||
|
||||
If the underlying IB device supports CQ event moderation, one can
|
||||
use ethtool to set interrupt mitigation parameters and thus reduce
|
||||
the overhead incurred by handling interrupts. The main code path of
|
||||
IPoIB doesn't use events for TX completion signaling so only RX
|
||||
moderation is supported.

rotary-encoder - a generic driver for GPIO connected devices
|
||||
Daniel Mack <daniel@caiaq.de>, Feb 2009

||||
|
||||
0. Function
|
||||
-----------
|
||||
|
||||
Rotary encoders are devices which are connected to the CPU or other
|
||||
peripherals with two wires. The outputs are phase-shifted by 90 degrees
|
||||
and by triggering on falling and rising edges, the turn direction can
|
||||
be determined.
|
||||
|
||||
The phase diagram of these two outputs look like this:
|
||||
|
||||

||||

|
||||
|
||||
|
||||
1. Events / state machine
|
||||
-------------------------
|
||||
|
||||
a) Rising edge on channel A, channel B in low state
|
||||
This state is used to recognize a clockwise turn
|
||||
|
||||
b) Rising edge on channel B, channel A in high state
|
||||
When entering this state, the encoder is put into 'armed' state,
|
||||
meaning that there it has seen half the way of a one-step transition.
|
||||
|
||||
c) Falling edge on channel A, channel B in high state
|
||||
This state is used to recognize a counter-clockwise turn
|
||||
|
||||
d) Falling edge on channel B, channel A in low state
|
||||
Parking position. If the encoder enters this state, a full transition
|
||||
should have happend, unless it flipped back on half the way. The
|
||||
'armed' state tells us about that.
|
||||
|
||||
2. Platform requirements
|
||||
------------------------
|
||||
|
||||
As there is no hardware dependent call in this driver, the platform it is
|
||||
used with must support gpiolib. Another requirement is that IRQs must be
|
||||
able to fire on both edges.
|
||||
|
||||
|
||||
3. Board integration
|
||||
--------------------
|
||||
|
||||
To use this driver in your system, register a platform_device with the
|
||||
name 'rotary-encoder' and associate the IRQs and some specific platform
|
||||
data with it.
|
||||
|
||||
struct rotary_encoder_platform_data is declared in
|
||||
include/linux/rotary-encoder.h and needs to be filled with the number of
|
||||
steps the encoder has and can carry information about externally inverted
|
||||
signals (because of used invertig buffer or other reasons).
|
||||
|
||||
Because GPIO to IRQ mapping is platform specific, this information must
|
||||
be given in seperately to the driver. See the example below.

2.1. Modules
|
||||
-------
|
||||
To get the device working, you have to load the proper kernel module. You
|
||||
can do this using
|
||||
modprobe modulename
|
||||
where modulename is ser_gigaset (M101), usb_gigaset (M105), or
|
||||
bas_gigaset (direct USB connection to the base).
|
||||
For the devices to work, the proper kernel modules have to be loaded.
|
||||
This normally happens automatically when the system detects the USB
|
||||
device (base, M105) or when the line discipline is attached (M101). It
|
||||
can also be triggered manually using the modprobe(8) command, for example
|
||||
for troubleshooting or to pass module parameters.
|
||||
|
||||
The module ser_gigaset provides a serial line discipline N_GIGASET_M101
|
||||
which drives the device through the regular serial line driver. To use it,
|
||||
run the Gigaset M101 daemon "gigasetm101d" (also available from
|
||||
http://sourceforge.net/projects/gigaset307x/) with the device file of the
|
||||
RS232 port to the M101 as an argument, for example:
|
||||
gigasetm101d /dev/ttyS1
|
||||
This will open the device file, set its line discipline to N_GIGASET_M101,
|
||||
and then sleep in the background, keeping the device open so that the
|
||||
line discipline remains active. To deactivate it, kill the daemon, for
|
||||
example with
|
||||
killall gigasetm101d
|
||||
before disconnecting the device.
|
||||
which drives the device through the regular serial line driver. It must
|
||||
be attached to the serial line to which the M101 is connected with the
|
||||
ldattach(8) command (requires util-linux-ng release 2.14 or later), for
|
||||
example:
|
||||
ldattach GIGASET_M101 /dev/ttyS1
|
||||
This will open the device file, attach the line discipline to it, and
|
||||
then sleep in the background, keeping the device open so that the line
|
||||
discipline remains active. To deactivate it, kill the daemon, for example
|
||||
with
|
||||
killall ldattach
|
||||
before disconnecting the device. To have this happen automatically at
|
||||
system startup/shutdown on an LSB compatible system, create and activate
|
||||
an appropriate LSB startup script /etc/init.d/gigaset. (The init name
|
||||
'gigaset' is officially assigned to this project by LANANA.)

Alternatively, just add the 'ldattach' command line to /etc/rc.local.

|
||||
The convention is to list one file per line and
|
||||
preferably in alphabetic order.
|
||||
|
||||
header-y also specify which subdirectories to visit.
|
||||
A subdirectory is identified by a trailing '/' which
|
||||
can be seen in the example above for the usb subdirectory.
|
||||
|
||||
Subdirectories are visited before their parent directories.

--- 7.2 objhdr-y
|
||||
|
||||
objhdr-y specifies generated files to be exported.
|
||||
Generated files are special as they need to be looked
|
||||
up in another directory when doing 'make O=...' builds.
|
||||
|
||||
Example:
|
||||
#include/linux/Kbuild
|
||||
objhdr-y += version.h
|
||||
|
||||
--- 7.3 destination-y
|
||||
|
||||
When an architecture have a set of exported headers that needs to be
|
||||
exported to a different directory destination-y is used.
|
||||
destination-y specify the destination directory for all exported
|
||||
headers in the file where it is present.
|
||||
|
||||
Example:
|
||||
#arch/xtensa/platforms/s6105/include/platform/Kbuild
|
||||
destination-y := include/linux
|
||||
|
||||
In the example above all exported headers in the Kbuild file
|
||||
will be located in the directory "include/linux" when exported.
|
||||
|
||||
|
||||
--- 7.4 unifdef-y (deprecated)
|
||||
|
||||
unifdef-y is deprecated. A direct replacement is header-y.

- It allows more than one jack detection method to work together on one
|
||||
user visible jack. In embedded systems it is common for multiple
|
||||
to be present on a single jack but handled by separate bits of
|
||||
hardware.
|
||||
|
||||
- Integration with DAPM, allowing DAPM endpoints to be updated
|
||||
automatically based on the detected jack status (eg, turning off the
|
||||
headphone outputs if no headphones are present).
|
||||
|
||||
This is done by splitting the jacks up into three things working
|
||||
together: the jack itself represented by a struct snd_soc_jack, sets of
|
||||
snd_soc_jack_pins representing DAPM endpoints to update and blocks of
|
||||
code providing jack reporting mechanisms.
|
||||
|
||||
For example, a system may have a stereo headset jack with two reporting
|
||||
mechanisms, one for the headphone and one for the microphone. Some
|
||||
systems won't be able to use their speaker output while a headphone is
|
||||
connected and so will want to make sure to update both speaker and
|
||||
headphone when the headphone jack status changes.
|
||||
|
||||
The jack - struct snd_soc_jack
|
||||
==============================
|
||||
|
||||
This represents a physical jack on the system and is what is visible to
|
||||
user space. The jack itself is completely passive, it is set up by the
|
||||
machine driver and updated by jack detection methods.
|
||||
|
||||
Jacks are created by the machine driver calling snd_soc_jack_new().
|
||||
|
||||
snd_soc_jack_pin
|
||||
================
|
||||
|
||||
These represent a DAPM pin to update depending on some of the status
|
||||
bits supported by the jack. Each snd_soc_jack has zero or more of these
|
||||
which are updated automatically. They are created by the machine driver
|
||||
and associated with the jack using snd_soc_jack_add_pins(). The status
|
||||
of the endpoint may configured to be the opposite of the jack status if
|
||||
required (eg, enabling a built in microphone if a microphone is not
|
||||
connected via a jack).
|
||||
|
||||
Jack detection methods
|
||||
======================
|
||||
|
||||
Actual jack detection is done by code which is able to monitor some
|
||||
input to the system and update a jack by calling snd_soc_jack_report(),
|
||||
specifying a subset of bits to update. The jack detection code should
|
||||
be set up by the machine driver, taking configuration for the jack to
|
||||
update and the set of things to report when the jack is connected.
|
||||
|
||||
Often this is done based on the status of a GPIO - a handler for this is
|
||||
provided by the snd_soc_jack_add_gpio() function. Other methods are
|
||||
also available, for example integrated into CODECs. One example of
|
||||
CODEC integrated jack detection can be see in the WM8350 driver.
|
||||
|
||||
Each jack may have multiple reporting mechanisms, though it will need at
|
||||
least one to be useful.
|
||||
|
||||
Machine drivers
|
||||
===============
|
||||
|
||||
These are all hooked together by the machine driver depending on the
|
||||
system hardware. The machine driver will set up the snd_soc_jack and
|
||||
the list of pins to update then set up one or more jack detection
|
||||
mechanisms to update that jack based on their current status.

--- What is TOMOYO? ---
|
||||
|
||||
TOMOYO is a name-based MAC extension (LSM module) for the Linux kernel.
|
||||
|
||||
LiveCD-based tutorials are available at
|
||||
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04-live/
|
||||
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
|
||||
Though these tutorials use non-LSM version of TOMOYO, they are useful for you
|
||||
to know what TOMOYO is.
|
||||
|
||||
--- How to enable TOMOYO? ---
|
||||
|
||||
Build the kernel with CONFIG_SECURITY_TOMOYO=y and pass "security=tomoyo" on
|
||||
kernel's command line.
|
||||
|
||||
Please see http://tomoyo.sourceforge.jp/en/2.2.x/ for details.
|

--- What is future plan? ---
|
||||
|
||||
We believe that inode based security and name based security are complementary
|
||||
and both should be used together. But unfortunately, so far, we cannot enable
|
||||
multiple LSM modules at the same time. We feel sorry that you have to give up
|
||||
SELinux/SMACK/AppArmor etc. when you want to use TOMOYO.
|
||||
|
||||
We hope that LSM becomes stackable in future. Meanwhile, you can use non-LSM
|
||||
version of TOMOYO, available at http://tomoyo.sourceforge.jp/en/1.6.x/ .
|
||||
LSM version of TOMOYO is a subset of non-LSM version of TOMOYO. We are planning
|
||||
to port non-LSM version's functionalities to LSM versions.

PXA-Camera Host Driver
|
||||
======================
|
||||
|
||||
Constraints
|
||||
-----------
|
||||
a) Image size for YUV422P format
|
||||
All YUV422P images are enforced to have width x height % 16 = 0.
|
||||
This is due to DMA constraints, which transfers only planes of 8 byte
|
||||
multiples.
|
||||
|
||||
|
||||
Global video workflow
|
||||
---------------------
|
||||
a) QCI stopped
|
||||
Initialy, the QCI interface is stopped.
|
||||
When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
|
||||
|
||||
b) QCI started
|
||||
More buffers can be queued while the QCI is started without halting the
|
||||
capture. The new buffers are "appended" at the tail of the DMA chain, and
|
||||
smoothly captured one frame after the other.
|
||||
|
||||
Once a buffer is filled in the QCI interface, it is marked as "DONE" and
|
||||
removed from the active buffers list. It can be then requeud or dequeued by
|
||||
userland application.
|
||||
|
||||
Once the last buffer is filled in, the QCI interface stops.
|
||||
|
||||
|
||||
DMA usage
|
||||
---------
|
||||
a) DMA flow
|
||||
- first buffer queued for capture
|
||||
Once a first buffer is queued for capture, the QCI is started, but data
|
||||
transfer is not started. On "End Of Frame" interrupt, the irq handler
|
||||
starts the DMA chain.
|
||||
- capture of one videobuffer
|
||||
The DMA chain starts transfering data into videobuffer RAM pages.
|
||||
When all pages are transfered, the DMA irq is raised on "ENDINTR" status
|
||||
- finishing one videobuffer
|
||||
The DMA irq handler marks the videobuffer as "done", and removes it from
|
||||
the active running queue
|
||||
Meanwhile, the next videobuffer (if there is one), is transfered by DMA
|
||||
- finishing the last videobuffer
|
||||
On the DMA irq of the last videobuffer, the QCI is stopped.
|
||||
|
||||
b) DMA prepared buffer will have this structure
|
||||
|
||||
+------------+-----+---------------+-----------------+
|
||||
| desc-sg[0] | ... | desc-sg[last] | finisher/linker |
|
||||
+------------+-----+---------------+-----------------+
|
||||
|
||||
This structure is pointed by dma->sg_cpu.
|
||||
The descriptors are used as follows :
|
||||
- desc-sg[i]: i-th descriptor, transfering the i-th sg
|
||||
element to the video buffer scatter gather
|
||||
- finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
|
||||
- linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
|
||||
|
||||
For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
|
||||
"f" stands for finisher and "l" for linker.
|
||||
A typical running chain is :
|
||||
|
||||
Videobuffer 1 Videobuffer 2
|
||||
+---------+----+---+ +----+----+----+---+
|
||||
| d0 | .. | dN | l | | d0 | .. | dN | f |
|
||||
+---------+----+-|-+ ^----+----+----+---+
|
||||
| |
|
||||
+----+
|
||||
|
||||
After the chaining is finished, the chain looks like :
|
||||
|
||||
Videobuffer 1 Videobuffer 2 Videobuffer 3
|
||||
+---------+----+---+ +----+----+----+---+ +----+----+----+---+
|
||||

||||
+----+ +----+
|
||||
new_link
|
||||
|
||||
c) DMA hot chaining timeslice issue
|
||||
|
||||
As DMA chaining is done while DMA _is_ running, the linking may be done
|
||||
while the DMA jumps from one Videobuffer to another. On the schema, that
|
||||
would be a problem if the following sequence is encountered :
|
||||
|
||||
- DMA chain is Videobuffer1 + Videobuffer2
|
||||
- pxa_videobuf_queue() is called to queue Videobuffer3
|
||||
- DMA controller finishes Videobuffer2, and DMA stops
|
||||
=>
|
||||
Videobuffer 1 Videobuffer 2
|
||||
+---------+----+---+ +----+----+----+---+
|
||||
| d0 | .. | dN | l | | d0 | .. | dN | f |
|
||||
+---------+----+-|-+ ^----+----+----+-^-+
|
||||
| | |
|
||||
+----+ +-- DMA DDADR loads DDADR_STOP
|
||||
|
||||
- pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
|
||||
replaced by a "linker" to Videobuffer3 (creation of new_link)
|
||||
- pxa_videobuf_queue() finishes
|
||||
- the DMA irq handler is called, which terminates Videobuffer2
|
||||
- Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
|
||||
|
||||
Videobuffer 1 Videobuffer 2 Videobuffer 3
|
||||
+---------+----+---+ +----+----+----+---+ +----+----+----+---+
|
||||
| d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
|
||||
+---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
|
||||
| | | |
|
||||
+----+ +----+
|
||||
new_link
|
||||
DMA DDADR still is DDADR_STOP
|
||||
|
||||
- pxa_camera_check_link_miss() is called
|
||||
This checks if the DMA is finished and a buffer is still on the
|
||||
pcdev->capture list. If that's the case, the capture will be restarted,
|
||||
and Videobuffer3 is scheduled on DMA chain.
|
||||
- the DMA irq handler finishes
|
||||
|
||||
Note: if DMA stops just after pxa_camera_check_link_miss() reads DDADR()
|
||||
value, we have the guarantee that the DMA irq handler will be called back
|
||||
when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
|
||||
be called again, to reschedule Videobuffer3.

|
||||
|
||||
Basically, the new setup is:
|
||||
|
||||
- we have "real address spaces" and "anonymous address spaces". The
|
||||
difference is that an anonymous address space doesn't care about the
|
||||
user-level page tables at all, so when we do a context switch into an
|
||||
anonymous address space we just leave the previous address space
|
||||
active.
|
||||
|
||||
The obvious use for a "anonymous address space" is any thread that
|
||||
doesn't need any user mappings - all kernel threads basically fall into
|
||||
this category, but even "real" threads can temporarily say that for
|
||||
some amount of time they are not going to be interested in user space,
|
||||
and that the scheduler might as well try to avoid wasting time on
|
||||
switching the VM state around. Currently only the old-style bdflush
|
||||
sync does that.
|
||||
|
||||
- "tsk->mm" points to the "real address space". For an anonymous process,
|
||||
tsk->mm will be NULL, for the logical reason that an anonymous process
|
||||
really doesn't _have_ a real address space at all.
|
||||
|
||||
- however, we obviously need to keep track of which address space we
|
||||
"stole" for such an anonymous user. For that, we have "tsk->active_mm",
|
||||
which shows what the currently active address space is.
|
||||
|
||||
The rule is that for a process with a real address space (ie tsk->mm is
|
||||
non-NULL) the active_mm obviously always has to be the same as the real
|
||||
one.
|
||||
|
||||
For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the
|
||||
"borrowed" mm while the anonymous process is running. When the
|
||||
anonymous process gets scheduled away, the borrowed address space is
|
||||
returned and cleared.
|
||||
|
||||
To support all that, the "struct mm_struct" now has two counters: a
|
||||
"mm_users" counter that is how many "real address space users" there are,
|
||||
and a "mm_count" counter that is the number of "lazy" users (ie anonymous
|
||||
users) plus one if there are any real users.
|
||||
|
||||
Usually there is at least one real user, but it could be that the real
|
||||
user exited on another CPU while a lazy user was still active, so you do
|
||||
actually get cases where you have a address space that is _only_ used by
|
||||
lazy users. That is often a short-lived state, because once that thread
|
||||
gets scheduled away in favour of a real thread, the "zombie" mm gets
|
||||
released because "mm_users" becomes zero.
|
||||
|
||||
Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any
|
||||
more. "init_mm" should be considered just a "lazy context when no other
|
||||
context is available", and in fact it is mainly used just at bootup when
|
||||
no real VM has yet been created. So code that used to check
|
||||
|
||||
if (current->mm == &init_mm)
|
||||
|
||||
should generally just do
|
||||
|
||||
if (!current->mm)
|
||||
|
||||
instead (which makes more sense anyway - the test is basically one of "do
|
||||
we have a user context", and is generally done by the page fault handler
|
||||
and things like that).
|
||||
|
||||
Anyway, I put a pre-patch-2.3.13-1 on ftp.kernel.org just a moment ago,
|
||||
because it slightly changes the interfaces to accomodate the alpha (who
|
||||
would have thought it, but the alpha actually ends up having one of the
|
||||
ugliest context switch codes - unlike the other architectures where the MM
|
||||
and register state is separate, the alpha PALcode joins the two, and you
|
||||
need to switch both together).
