Description: The /sys/dev tree provides a method to look up the sysfs
|
||||
path for a device using the information returned from
|
||||
stat(2). There are two directories, 'block' and 'char',
|
||||
beneath /sys/dev containing symbolic links with names of
|
||||
the form "<major>:<minor>". These links point to the
|
||||
corresponding sysfs path for the given device.
|
||||
|
||||
Example:
|
||||
$ readlink /sys/dev/block/8:32
|
||||
../../block/sdc
|
||||
|
||||
Entries in /sys/dev/char and /sys/dev/block will be
|
||||
dynamically created and destroyed as devices enter and
|
||||
leave the system.

For some hardware that has more than one interrupt source internally,
|
||||
but not separate IRQ mask and status registers, there might be
|
||||
situations where userspace cannot determine what the interrupt source
|
||||
was if the kernel handler disables them by writing to the chip's IRQ
|
||||
register. In such a case, the kernel has to disable the IRQ completely
|
||||
to leave the chip's register untouched. Now the userspace part can
|
||||
determine the cause of the interrupt, but it cannot re-enable
|
||||
interrupts. Another cornercase is chips where re-enabling interrupts
|
||||
is a read-modify-write operation to a combined IRQ status/acknowledge
|
||||
register. This would be racy if a new interrupt occurred
|

simultaneously.

== For advanced documentation, see ==

|

===============================================================
|

|

|
||||
A generic digital 24-port PCI GPIO card can be built out of an ordinary
|
||||
Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
|
||||
Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily
|
||||
find them used for low prices on the net.
|
||||
|
||||
The bt8xx chip does have 24 digital GPIO ports.
|
||||
These ports are accessible via 24 pins on the SMD chip package.
|
||||
|
||||
|
||||
==============================================
|
||||
== How to physically access the GPIO pins ==
|
||||
==============================================
|
||||
|
||||
The are several ways to access these pins. One might unsolder the whole chip
|
||||
and put it on a custom PCI board, or one might only unsolder each individual
|
||||
GPIO pin and solder that to some tiny wire. As the chip package really is tiny
|
||||
there are some advanced soldering skills needed in any case.
|
||||
|
||||
The physical pinouts are drawn in the following ASCII art.

SH7760/SH7763 integrated LCDC Framebuffer driver
|
||||
================================================
|
||||
|
||||
0. Overwiew
|
||||
-----------
|
||||
The SH7760/SH7763 have an integrated LCD Display controller (LCDC) which
|
||||
supports (in theory) resolutions ranging from 1x1 to 1024x1024,
|
||||
with color depths ranging from 1 to 16 bits, on STN, DSTN and TFT Panels.
|
||||
|
||||
Caveats:
|
||||
* Framebuffer memory must be a large chunk allocated at the top
|
||||
of Area3 (HW requirement). Because of this requirement you should NOT
|
||||
make the driver a module since at runtime it may become impossible to
|
||||
get a large enough contiguous chunk of memory.
|
||||
|
||||
* The driver does not support changing resolution while loaded
|
||||
(displays aren't hotpluggable anyway)
|
||||
|
||||
* Heavy flickering may be observed
|
||||
a) if you're using 15/16bit color modes at >= 640x480 px resolutions,
|
||||
b) during PCMCIA (or any other slow bus) activity.
|
||||
|
||||
* Rotation works only 90degress clockwise, and only if horizontal
|
||||
resolution is <= 320 pixels.

|
||||
|
||||
1. Platform setup
|
||||
-----------------
|
||||
SH7760:
|
||||
Video data is fetched via the DMABRG DMA engine, so you have to
|
||||
configure the SH DMAC for DMABRG mode (write 0x94808080 to the
|
||||
DMARSRA register somewhere at boot).
|
||||
|
||||
PFC registers PCCR and PCDR must be set to peripheral mode.
|
||||
(write zeros to both).
|
||||
|
||||
The driver does NOT do the above for you since board setup is, well, job
|
||||
of the board setup code.
|
||||
|
||||
2. Panel definitions
|
||||
--------------------
|
||||
The LCDC must explicitly be told about the type of LCD panel
|
||||
attached. Data must be wrapped in a "struct sh7760fb_platdata" and
|
||||
passed to the driver as platform_data.
|
||||
|
||||
Suggest you take a closer look at the SH7760 Manual, Section 30.
|
||||

|
||||
All families are accelerated. Only PCI/AGP based cards are supported,
|
||||
none of the older Tridents.
|
||||
The driver supports 8, 16 and 32 bits per pixel depths.
|
||||
The TGUI family requires a line length to be power of 2 if acceleration
|
||||
is enabled. This means that range of possible resolutions and bpp is
|
||||
limited comparing to the range if acceleration is disabled (see list
|
||||
of parameters below).
|
||||
|
||||
Known bugs:
|
||||
1. The driver randomly locks up on 3DImage975 chip with acceleration
|
||||
enabled. The same happens in X11 (Xorg).
|
||||
2. The ramdac speeds require some more fine tuning. It is possible to
|
||||
switch resolution which the chip does not support at some depths for
|
||||
older chips.

Sysfs Interface for Userspace (OPTIONAL)
|
||||
========================================
|
||||
Platforms which use the "gpiolib" implementors framework may choose to
|
||||
configure a sysfs user interface to GPIOs. This is different from the
|
||||
debugfs interface, since it provides control over GPIO direction and
|
||||
value instead of just showing a gpio state summary. Plus, it could be
|
||||
present on production systems without debugging support.
|
||||
|
||||
Given approprate hardware documentation for the system, userspace could
|
||||
know for example that GPIO #23 controls the write protect line used to
|
||||
protect boot loader segments in flash memory. System upgrade procedures
|
||||
may need to temporarily remove that protection, first importing a GPIO,
|
||||
then changing its output state, then updating the code before re-enabling
|
||||
the write protection. In normal use, GPIO #23 would never be touched,
|
||||
and the kernel would have no need to know about it.
|
||||
|
||||
Again depending on appropriate hardware documentation, on some systems
|
||||
userspace GPIO can be used to determine system configuration data that
|
||||
standard kernels won't know about. And for some tasks, simple userspace
|
||||
GPIO drivers could be all that the system really needs.
|
||||
|
||||
Note that standard kernel drivers exist for common "LEDs and Buttons"
|
||||
GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
|
||||
instead of talking directly to the GPIOs; they integrate with kernel
|
||||
frameworks better than your userspace code could.
|
||||
|
||||
|
||||
Paths in Sysfs
|
||||
--------------
|
||||
There are three kinds of entry in /sys/class/gpio:
|
||||
|
||||
- Control interfaces used to get userspace control over GPIOs;
|
||||
|
||||
- GPIOs themselves; and
|
||||
|
||||
- GPIO controllers ("gpio_chip" instances).
|
||||
|
||||
That's in addition to standard files including the "device" symlink.
|
||||
|
||||
The control interfaces are write-only:
|
||||
|
||||
/sys/class/gpio/
|
||||
|
||||
"export" ... Userspace may ask the kernel to export control of
|
||||
a GPIO to userspace by writing its number to this file.
|
||||
|
||||
Example: "echo 19 > export" will create a "gpio19" node
|
||||
for GPIO #19, if that's not requested by kernel code.
|
||||
|
||||
"unexport" ... Reverses the effect of exporting to userspace.
|
||||
|
||||
Example: "echo 19 > unexport" will remove a "gpio19"
|
||||
node exported using the "export" file.
|
||||
|
||||
GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
|
||||
and have the following read/write attributes:
|
||||
|
||||
/sys/class/gpio/gpioN/
|
||||
|
||||
"direction" ... reads as either "in" or "out". This value may
|
||||
normally be written. Writing as "out" defaults to
|
||||
initializing the value as low. To ensure glitch free
|
||||
operation, values "low" and "high" may be written to
|
||||
configure the GPIO as an output with that initial value.
|
||||
|
||||
Note that this attribute *will not exist* if the kernel
|
||||
doesn't support changing the direction of a GPIO, or
|
||||
it was exported by kernel code that didn't explicitly
|
||||
allow userspace to reconfigure this GPIO's direction.
|
||||
|
||||
"value" ... reads as either 0 (low) or 1 (high). If the GPIO
|
||||
is configured as an output, this value may be written;
|
||||
any nonzero value is treated as high.
|
||||
|
||||
GPIO controllers have paths like /sys/class/gpio/chipchip42/ (for the
|
||||
controller implementing GPIOs starting at #42) and have the following
|
||||
read-only attributes:
|
||||
|
||||
/sys/class/gpio/gpiochipN/
|
||||
|
||||
"base" ... same as N, the first GPIO managed by this chip
|
||||
|
||||
"label" ... provided for diagnostics (not always unique)
|
||||
|
||||
"ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
|
||||
|
||||
Board documentation should in most cases cover what GPIOs are used for
|
||||
what purposes. However, those numbers are not always stable; GPIOs on
|
||||
a daughtercard might be different depending on the base board being used,
|
||||
or other cards in the stack. In such cases, you may need to use the
|
||||
gpiochip nodes (possibly in conjunction with schematics) to determine
|
||||
the correct GPIO number to use for a given signal.
|
||||
|
||||
|
||||
Exporting from Kernel code
|
||||
--------------------------
|
||||
Kernel code can explicitly manage exports of GPIOs which have already been
|
||||
requested using gpio_request():
|
||||
|
||||
/* export the GPIO to userspace */
|
||||
int gpio_export(unsigned gpio, bool direction_may_change);
|
||||
|
||||
/* reverse gpio_export() */
|
||||
void gpio_unexport();
|
||||
|
||||
After a kernel driver requests a GPIO, it may only be made available in
|
||||
the sysfs interface by gpio_export(). The driver can control whether the
|
||||
signal direction may change. This helps drivers prevent userspace code
|
||||
from accidentally clobbering important system state.
|
||||
|
||||
This explicit exporting can help with debugging (by making some kinds
|
||||
of experiments easier), or can provide an always-there interface that's
|
||||
suitable for documenting as part of a board support package.

||||
first step, anyway, is to copy driver file "mxser.tgz" into specified
|
||||
directory. e.g. /moxa. The execute commands as below.
|
||||
|
||||
# cd /
|
||||
# mkdir moxa

||||
# cd /moxa
|

# cp /mnt/cdrom/<driver directory>/mxser.tgz .
|
||||
# tar xvfz mxser.tgz
|
||||
|
||||
|
||||
3.3 Device naming convention
|
||||
|
||||
You may find all the driver and utilities files in /moxa/mxser.
|
||||
Following installation procedure depends on the model you'd like to

3.3 Module driver configuration
|
||||
3.4 Module driver configuration
|
||||
Module driver is easiest way to install. If you prefer static driver
|
||||
installation, please skip this paragraph.
|
||||
1. Find "Makefile" in /moxa/mxser, then run
|
||||
|
||||
# make install
|
||||
|
||||
The driver files "mxser.o" and utilities will be properly compiled
|
||||
and copied to system directories respectively.Then run
|
||||
------------- Prepare to use the MOXA driver--------------------
|
||||
3.4.1 Create tty device with correct major number
|
||||
Before using MOXA driver, your system must have the tty devices
|
||||
which are created with driver's major number. We offer one shell
|
||||
script "msmknod" to simplify the procedure.
|
||||
This step is only needed to be executed once. But you still
|
||||
need to do this procedure when:
|
||||
a. You change the driver's major number. Please refer the "3.7"
|
||||
section.
|
||||
b. Your total installed MOXA boards number is changed. Maybe you
|
||||
add/delete one MOXA board.
|
||||
c. You want to change the tty name. This needs to modify the
|
||||
shell script "msmknod"
|
||||
|
||||
# insmod mxser
|
||||
|
||||
to activate the modular driver. You may run "lsmod" to check
|
||||
if "mxser.o" is activated.
|
||||
|
||||
2. Create special files by executing "msmknod".
|
||||
The procedure is:
|
||||
# cd /moxa/mxser/driver
|
||||
# ./msmknod
|
||||
|
||||
Default major numbers for dial-in device and callout device are
|
||||
174, 175. Msmknod will delete any special files occupying the same
|
||||
device naming.
|
||||
This shell script will require the major number for dial-in
|
||||
device and callout device to create tty device. You also need
|
||||
to specify the total installed MOXA board number. Default major
|
||||
numbers for dial-in device and callout device are 30, 35. If
|
||||
you need to change to other number, please refer section "3.7"
|
||||
for more detailed procedure.
|
||||
Msmknod will delete any special files occupying the same device
|
||||
naming.
|
||||
|
||||
3. Up to now, you may manually execute "insmod mxser" to activate
|
||||
this driver and run "rmmod mxser" to remove it. However, it's
|
||||
better to have a boot time configuration to eliminate manual
|
||||
operation.
|
||||
Boot time configuration can be achieved by rc file. Run following
|
||||
command for setting rc files.
|
||||
3.4.2 Build the MOXA driver and utilities
|
||||
Before using the MOXA driver and utilities, you need compile the
|
||||
all the source code. This step is only need to be executed once.
|
||||
But you still re-compile the source code if you modify the source
|
||||
code. For example, if you change the driver's major number (see
|
||||
"3.7" section), then you need to do this step again.
|
||||
|
||||
Find "Makefile" in /moxa/mxser, then run
|
||||
|
||||
# make clean; make install
|
||||
|
||||
!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
|
||||
For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
|
||||
# make clean; make installsp1
|
||||
|
||||
For Red Hat Enterprise Linux AS4/ES4/WS4:
|
||||
# make clean; make installsp2
|
||||
!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
|
||||
|
||||
The driver files "mxser.o" and utilities will be properly compiled
|
||||
and copied to system directories respectively.
|
||||
|
||||
------------- Load MOXA driver--------------------
|
||||
3.4.3 Load the MOXA driver
|
||||
|
||||
# modprobe mxser <argument>
|
||||
|
||||
will activate the module driver. You may run "lsmod" to check
|
||||
if "mxser" is activated. If the MOXA board is ISA board, the
|
||||
<argument> is needed. Please refer to section "3.4.5" for more
|
||||
information.
|
||||
|
||||
|
||||
------------- Load MOXA driver on boot --------------------
|
||||
3.4.4 For the above description, you may manually execute
|
||||
"modprobe mxser" to activate this driver and run
|
||||
"rmmod mxser" to remove it.
|
||||
However, it's better to have a boot time configuration to
|
||||
eliminate manual operation. Boot time configuration can be
|
||||
achieved by rc file. We offer one "rc.mxser" file to simplify
|
||||
the procedure under "moxa/mxser/driver".
|
||||
|
||||
But if you use ISA board, please modify the "modprobe ..." command
|
||||
to add the argument (see "3.4.5" section). After modifying the
|
||||
rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
|
||||
manually to make sure the modification is ok. If any error
|
||||
encountered, please try to modify again. If the modification is
|
||||
completed, follow the below step.
|
||||
|
||||
Run following command for setting rc files.
|
||||
|
||||
# cd /moxa/mxser/driver
|
||||
# cp ./rc.mxser /etc/rc.d
|
||||
# cd /etc/rc.d
|
||||
|
||||
You may have to modify part of the content in rc.mxser to specify
|
||||
parameters for ISA board. Please refer to rc.mxser for more detail.
|
||||
Find "rc.serial". If "rc.serial" doesn't exist, create it by vi.
|
||||
Add "rc.mxser" in last line. Next, open rc.local by vi
|
||||
and append following content.
|
||||
Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
|
||||
create it by vi, run "chmod 755 rc.serial" to change the permission.
|
||||
Add "/etc/rc.d/rc.mxser" in last line,
|
||||
|
||||
if [ -f /etc/rc.d/rc.serial ]; then
|
||||
sh /etc/rc.d/rc.serial
|
||||
fi
|
||||
Reboot and check if moxa.o activated by "lsmod" command.
|
||||
|
||||
4. Reboot and check if mxser.o activated by "lsmod" command.
|
||||
5. If you'd like to drive Smartio ISA boards in the system, you'll
|
||||
have to add parameter to specify CAP address of given board while
|
||||
activating "mxser.o". The format for parameters are as follows.
|
||||
3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system,
|
||||
you'll have to add parameter to specify CAP address of given
|
||||
board while activating "mxser.o". The format for parameters are
|
||||
as follows.
|
||||
|
||||
insmod mxser ioaddr=0x???,0x???,0x???,0x???

3.4 Static driver configuration
|
||||
3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
|
||||
|
||||
1. Create link
|
||||
Note: To use static driver, you must install the linux kernel
|
||||
source package.
|
||||
|
||||
3.5.1 Backup the built-in driver in the kernel.
|
||||
# cd /usr/src/linux/drivers/char
|
||||
# mv mxser.c mxser.c.old
|
||||
|
||||
For Red Hat 7.x user, you need to create link:
|
||||
# cd /usr/src
|
||||
# ln -s linux-2.4 linux
|
||||
|
||||
3.5.2 Create link
|

If 'lilo' utility is installed, please use 'make zlilo' to rebuild
|
||||
kernel. If 'lilo' is not installed, please follow the following steps.
|
||||
|
||||
a. cd /usr/src/linux
|
||||
b. make clean /* take a few minutes */
|
||||
c. make bzImage /* take probably 10-20 minutes */
|
||||
d. Backup original boot kernel. /* optional step */
|
||||
e. cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz
|

b. make clean /* take a few minutes */
|
||||
c. make dep /* take a few minutes */
|
||||
d. make bzImage /* take probably 10-20 minutes */
|
||||
e. make install /* copy boot image to correct position */
|
||||
f. Please make sure the boot kernel (vmlinuz) is in the
|
||||
correct position. If you use 'lilo' utility, you should
|
||||
check /etc/lilo.conf 'image' item specified the path
|
||||
which is the 'vmlinuz' path, or you will load wrong
|
||||
(or old) boot kernel image (vmlinuz).
|
||||
g. chmod 400 /vmlinuz
|
||||
h. lilo

|
||||
or you will load wrong (or old) boot kernel image (vmlinuz).
|
||||
After checking /etc/lilo.conf, please run "lilo".
|
||||
|
||||
Note that if the result of "make zImage" is ERROR, then you have to
|
||||
go back to Linux configuration Setup. Type "make config" in directory

APM or ACPI?
|
||||
------------
|
||||
If you have a relatively recent x86 mobile, desktop, or server system,
|
||||
odds are it supports either Advanced Power Management (APM) or
|
||||
Advanced Configuration and Power Interface (ACPI). ACPI is the newer
|
||||
of the two technologies and puts power management in the hands of the
|
||||
operating system, allowing for more intelligent power management than
|
||||
is possible with BIOS controlled APM.
|
||||
|
||||
The best way to determine which, if either, your system supports is to
|
||||
build a kernel with both ACPI and APM enabled (as of 2.3.x ACPI is
|
||||
enabled by default). If a working ACPI implementation is found, the
|
||||
ACPI driver will override and disable APM, otherwise the APM driver
|
||||
will be used.
|
||||
|
||||
No, sorry, you cannot have both ACPI and APM enabled and running at
|
||||
once. Some people with broken ACPI or broken APM implementations
|
||||
would like to use both to get a full set of working features, but you
|
||||
simply cannot mix and match the two. Only one power management
|
||||
interface can be in control of the machine at once. Think about it..
|
||||
|
||||
User-space Daemons
|
||||
------------------
|
||||
Both APM and ACPI rely on user-space daemons, apmd and acpid
|
||||
respectively, to be completely functional. Obtain both of these
|
||||
daemons from your Linux distribution or from the Internet (see below)
|
||||
and be sure that they are started sometime in the system boot process.
|
||||
Go ahead and start both. If ACPI or APM is not available on your
|
||||
system the associated daemon will exit gracefully.

Linux Power Management Support
|

This document briefly describes how to use power management with your
|
||||
Linux system and how to add power management support to Linux drivers.

Driver Interface -- OBSOLETE, DO NOT USE!
|
||||
----------------*************************
|
||||
|
||||
Note: pm_register(), pm_access(), pm_dev_idle() and friends are
|
||||
obsolete. Please do not use them. Instead you should properly hook
|
||||
your driver into the driver model, and use its suspend()/resume()
|
||||
callbacks to do this kind of stuff.
|
||||
|
||||
If you are writing a new driver or maintaining an old driver, it
|
||||
should include power management support. Without power management
|
||||
support, a single driver may prevent a system with power management
|
||||
capabilities from ever being able to suspend (safely).
|
||||
|
||||
Overview:
|
||||
1) Register each instance of a device with "pm_register"
|
||||
2) Call "pm_access" before accessing the hardware.
|
||||
(this will ensure that the hardware is awake and ready)
|
||||
3) Your "pm_callback" is called before going into a
|
||||
suspend state (ACPI D1-D3) or after resuming (ACPI D0)
|
||||
from a suspend.
|
||||
4) Call "pm_dev_idle" when the device is not being used
|
||||
(optional but will improve device idle detection)
|
||||
5) When unloaded, unregister the device with "pm_unregister"

Driver Details
|
||||
--------------
|
||||
This is just a quick Q&A as a stopgap until a real driver writers'
|
||||
power management guide is available.
|
||||
|
||||
Q: When is a device suspended?
|
||||
|
||||
Devices can be suspended based on direct user request (eg. laptop lid
|
||||
closes), system power policy (eg. sleep after 30 minutes of console
|
||||
inactivity), or device power policy (eg. power down device after 5
|
||||
minutes of inactivity)
|
||||
|
||||
Q: Must a driver honor a suspend request?
|
||||
|
||||
No, a driver can return -EBUSY from a suspend request and this
|
||||
will stop the system from suspending. When a suspend request
|
||||
fails, all suspended devices are resumed and the system continues
|
||||
to run. Suspend can be retried at a later time.
|
||||
|
||||
Q: Can the driver block suspend/resume requests?
|
||||
|
||||
Yes, a driver can delay its return from a suspend or resume
|
||||
request until the device is ready to handle requests. It
|
||||
is advantageous to return as quickly as possible from a
|
||||
request as suspend/resume are done serially.
|
||||
|
||||
Q: What context is a suspend/resume initiated from?
|
||||
|
||||
A suspend or resume is initiated from a kernel thread context.
|
||||
It is safe to block, allocate memory, initiate requests
|
||||
or anything else you can do within the kernel.
|
||||
|
||||
Q: Will requests continue to arrive after a suspend?
|
||||
|
||||
Possibly. It is the driver's responsibility to queue(*),
|
||||
fail, or drop any requests that arrive after returning
|
||||
success to a suspend request. It is important that the
|
||||
driver not access its device until after it receives
|
||||
a resume request as the device's bus may no longer
|
||||
be active.
|
||||
|
||||
(*) If a driver queues requests for processing after
|
||||
resume be aware that the device, network, etc.
|
||||
might be in a different state than at suspend time.
|
||||
It's probably better to drop requests unless
|
||||
the driver is a storage device.
|
||||
|
||||
Q: Do I have to manage bus-specific power management registers
|
||||
|
||||
No. It is the responsibility of the bus driver to manage
|
||||
PCI, USB, etc. power management registers. The bus driver
|
||||
or the power management subsystem will also enable any
|
||||
wake-on functionality that the device has.
|
||||
|
||||
Q: So, really, what do I need to do to support suspend/resume?
|
||||
|
||||
You need to save any device context that would
|
||||
be lost if the device was powered off and then restore
|
||||
it at resume time. When ACPI is active, there are
|
||||
three levels of device suspend states; D1, D2, and D3.
|
||||
(The suspend state is passed as the "data" argument
|
||||
to the device callback.) With D3, the device is powered
|
||||
off and loses all context, D1 and D2 are shallower power
|
||||
states and require less device context to be saved. To
|
||||
play it safe, just save everything at suspend and restore
|
||||
everything at resume.
|
||||
|
||||
Q: Where do I store device context for suspend?
|
||||
|
||||
Anywhere in memory, kmalloc a buffer or store it
|
||||
in the device descriptor. You are guaranteed that the
|
||||
contents of memory will be restored and accessible
|
||||
before resume, even when the system suspends to disk.
|
||||
|
||||
Q: What do I need to do for ACPI vs. APM vs. etc?
|
||||
|
||||
Drivers need not be aware of the specific power management
|
||||
technology that is active. They just need to be aware
|
||||
of when the overlying power management system requests
|
||||
that they suspend or resume.
|
||||
|
||||
Q: What about device dependencies?
|
||||
|
||||
When a driver registers a device, the power management
|
||||
subsystem uses the information provided to build a
|
||||
tree of device dependencies (eg. USB device X is on
|
||||
USB controller Y which is on PCI bus Z) When power
|
||||
management wants to suspend a device, it first sends
|
||||
a suspend request to its driver, then the bus driver,
|
||||
and so on up to the system bus. Device resumes
|
||||
proceed in the opposite direction.
|
||||
|
||||
Q: Who do I contact for additional information about
|
||||
enabling power management for my specific driver/device?

s) SPI (Serial Peripheral Interface) busses
|
||||
|
||||
SPI busses can be described with a node for the SPI master device
|
||||
and a set of child nodes for each SPI slave on the bus. For this
|
||||
discussion, it is assumed that the system's SPI controller is in
|
||||
SPI master mode. This binding does not describe SPI controllers
|
||||
in slave mode.
|
||||
|
||||
The SPI master node requires the following properties:
|
||||
- #address-cells - number of cells required to define a chip select
|
||||
address on the SPI bus.
|
||||
- #size-cells - should be zero.
|
||||
- compatible - name of SPI bus controller following generic names
|
||||
recommended practice.
|
||||
No other properties are required in the SPI bus node. It is assumed
|
||||
that a driver for an SPI bus device will understand that it is an SPI bus.
|
||||
However, the binding does not attempt to define the specific method for
|
||||
assigning chip select numbers. Since SPI chip select configuration is
|
||||
flexible and non-standardized, it is left out of this binding with the
|
||||
assumption that board specific platform code will be used to manage
|
||||
chip selects. Individual drivers can define additional properties to
|
||||
support describing the chip select layout.
|
||||
|
||||
SPI slave nodes must be children of the SPI master node and can
|
||||
contain the following properties.
|
||||
- reg - (required) chip select address of device.
|
||||
- compatible - (required) name of SPI device following generic names
|
||||
recommended practice
|
||||
- spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
|
||||
- spi-cpol - (optional) Empty property indicating device requires

inverse clock polarity (CPOL) mode

X - Specifying Device Power Management Information (sleep property)
|
||||
===================================================================
|
||||
|
||||
Devices on SOCs often have mechanisms for placing devices into low-power
|
||||
states that are decoupled from the devices' own register blocks. Sometimes,
|
||||
this information is more complicated than a cell-index property can
|
||||
reasonably describe. Thus, each device controlled in such a manner
|
||||
may contain a "sleep" property which describes these connections.
|
||||
|
||||
The sleep property consists of one or more sleep resources, each of
|
||||
which consists of a phandle to a sleep controller, followed by a
|
||||
controller-specific sleep specifier of zero or more cells.
|
||||
|
||||
The semantics of what type of low power modes are possible are defined
|
||||
by the sleep controller. Some examples of the types of low power modes
|
||||
that may be supported are:
|
||||
|
||||
- Dynamic: The device may be disabled or enabled at any time.
|
||||
- System Suspend: The device may request to be disabled or remain
|
||||
awake during system suspend, but will not be disabled until then.
|
||||
- Permanent: The device is disabled permanently (until the next hard
|
||||
reset).
|
||||
|
||||
Some devices may share a clock domain with each other, such that they should
|
||||
only be suspended when none of the devices are in use. Where reasonable,
|
||||
such nodes should be placed on a virtual bus, where the bus has the sleep
|
||||
property. If the clock domain is shared among devices that cannot be
|
||||
reasonably grouped in this manner, then create a virtual sleep controller
|
||||
(similar to an interrupt nexus, except that defining a standardized
|
||||
sleep-map should wait until its necessity is demonstrated).

- compatible: "fsl,<chip>-pmc".
|

"fsl,mpc8349-pmc" should be listed for any chip whose PMC is
|
||||
compatible. "fsl,mpc8313-pmc" should also be listed for any chip
|
||||
whose PMC is compatible, and implies deep-sleep capability.
|

whose PMC is compatible, and implies deep-sleep capability.
|

"fsl,mpc8641d-pmc" should be listed for any chip whose PMC is
|
||||
compatible; all statements below that apply to "fsl,mpc8548-pmc" also
|
||||
apply to "fsl,mpc8641d-pmc".
|
||||
|
||||
Compatibility does not include bit assigments in SCCR/PMCDR/DEVDISR; these
|
||||
bit assigments are indicated via the sleep specifier in each device's
|
||||
sleep property.
|
||||
|
||||
- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
|
||||
is the PMC block, and the second resource is the Clock Configuration
|
||||
block.
|
||||
|
||||
For devices compatible with "fsl,mpc8548-pmc", the first resource
|
||||
is a 32-byte block beginning with DEVDISR.
|
||||
|
||||
- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
|
||||
resource is the PMC block interrupt.
|
||||
|
||||
- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
|
||||
this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
|
||||
a wakeup source from deep sleep.
|
||||
|
||||
Sleep specifiers:
|
||||
|
||||
fsl,mpc8349-pmc: Sleep specifiers consist of one cell. For each bit
|
||||
that is set in the cell, the corresponding bit in SCCR will be saved
|
||||
and cleared on suspend, and restored on resume. This sleep controller
|
||||
supports disabling and resuming devices at any time.
|
||||
|
||||
fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
|
||||
which will be ORed into PMCDR upon suspend, and cleared from PMCDR
|
||||
upon resume. The first two cells are as described for fsl,mpc8578-pmc.
|
||||
This sleep controller only supports disabling devices during system
|
||||
sleep, or permanently.
|
||||
|
||||
fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
|
||||
first of which will be ORed into DEVDISR (and the second into
|
||||
DEVDISR2, if present -- this cell should be zero or absent if the
|
||||
hardware does not have DEVDISR2) upon a request for permanent device
|
||||
disabling. This sleep controller does not support configuring devices
|
||||
to disable during system sleep (unless supported by another compatible
|
||||
match), or dynamically.
|
||||
|
||||
Example:
|

The kernel-exported sysfs exports internal kernel implementation details

Alignment vs. Networking
|
||||
========================
|
||||
|
||||
On architectures that require aligned loads, networking requires that the IP
|
||||
header is aligned on a four-byte boundary to optimise the IP stack. For
|
||||
regular ethernet hardware, the constant NET_IP_ALIGN is used. On most
|
||||
architectures this constant has the value 2 because the normal ethernet
|
||||
header is 14 bytes long, so in order to get proper alignment one needs to
|
||||
DMA to an address which can be expressed as 4*n + 2. One notable exception
|
||||
here is powerpc which defines NET_IP_ALIGN to 0 because DMA to unaligned
|
||||
addresses can be very expensive and dwarf the cost of unaligned loads.
|
||||
|
||||
For some ethernet hardware that cannot DMA to unaligned addresses like
|
||||
4*n+2 or non-ethernet hardware, this can be a problem, and it is then
|
||||
required to copy the incoming frame into an aligned buffer. Because this is
|
||||
unnecessary on architectures that can do unaligned accesses, the code can be
|
||||
made dependent on CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS like so:
|
||||
|
||||
#ifdef CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
|
||||
skb = original skb
|
||||
#else
|
||||
skb = copy skb
|
||||
#endif
