So, you can either get rid of GNU emacs, or change it to use saner
values. To do the latter, you can stick the following in your .emacs file:
(defun linux-c-mode ()
"C mode with adjusted defaults for use with the Linux kernel."
(interactive)
(c-mode)
(c-set-style "K&R")
(setq tab-width 8)
(setq indent-tabs-mode t)
(setq c-basic-offset 8))
(defun c-lineup-arglist-tabs-only (ignored)

(let* ((anchor (c-langelem-pos c-syntactic-element))
(column (c-langelem-2nd-pos c-syntactic-element))
(offset (- (1+ column) anchor))
(steps (floor offset c-basic-offset)))
(* (max steps 1)
c-basic-offset)))
This will define the M-x linux-c-mode command. When hacking on a
module, if you put the string -*- linux-c -*- somewhere on the first
two lines, this mode will be automatically invoked. Also, you may want
to add
(add-hook 'c-mode-hook
(lambda ()
(let ((filename (buffer-file-name)))
;; Enable kernel mode for the appropriate files
(when (and filename
(string-match "~/src/linux-trees" filename))
(setq indent-tabs-mode t)
(c-set-style "linux")

c-lineup-arglist-tabs-only))))))
(setq auto-mode-alist (cons '("/usr/src/linux.*/.*\\.[ch]$" . linux-c-mode)
auto-mode-alist))
to your .emacs file if you want to have linux-c-mode switched on
automagically when you edit source files under /usr/src/linux.
This will make emacs go better with the kernel coding style for C
files below ~/src/linux-trees.
But even if you fail in getting emacs to do sane formatting, not
everything is lost: use "indent".

== For advanced documentation, see ==
== http://www.bu3sch.de/btgpio.php ==
===============================================================
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.
The GPIO pins are marked with G00-G23

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.
(http://documentation.renesas.com/eng/products/mpumcu/e602291_sh7760.pdf)

@ -3,11 +3,25 @@ Tridentfb is a framebuffer driver for some Trident chip based cards.
The following list of chips is thought to be supported although not all are
tested:
those from the Image series with Cyber in their names - accelerated
those with Blade in their names (Blade3D,CyberBlade...) - accelerated
the newer CyberBladeXP family - nonaccelerated
those from the TGUI series 9440/96XX and with Cyber in their names

Only PCI/AGP based cards are supported, none of the older Tridents.
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.

To support this framework, a platform's Kconfig will "select" either

They may also want to provide a custom value for ARCH_NR_GPIOS.
ARCH_REQUIRE_GPIOLIB means that the gpio-lib code will always get compiled
into the kernel on that architecture.
ARCH_WANT_OPTIONAL_GPIOLIB means the gpio-lib code defaults to off and the user
can enable it and build it into the kernel optionally.
If neither of these options are selected, the platform does not support
GPIOs through GPIO-lib and the code cannot be enabled by the user.

once all the necessary resources are available, and remove them later when
the GPIO controller device becomes unavailable.
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.

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

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.

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?
ACPI Development mailing list: linux-acpi@vger.kernel.org
System Interface -- OBSOLETE, DO NOT USE!
----------------*************************
If you are providing new power management support to Linux (ie.
adding support for something like APM or ACPI), you should
communicate with drivers through the existing generic power
management interface.

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
- spi-cpha - (optional) Empty property indicating device requires
shifted clock phase (CPHA) mode
SPI example for an MPC5200 SPI bus:
spi@f00 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
reg = <0xf00 0x20>;

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

Some architectures are unable to perform unaligned accesses
without the use of get_unaligned/put_unaligned. Others are
unable to perform such accesses efficiently (e.g. trap on
unaligned access and require fixing it up in the exception
handler.)
This symbol should be selected by an architecture if it can
perform unaligned accesses efficiently to allow different
code paths to be selected for these cases. Some network
drivers, for example, could opt to not fix up alignment
problems with received packets if doing so would not help
much.

help
The maximum number of Unix98 PTYs that can be used at any one time.
The default is 256, and should be enough for desktop systems. Server
machines which support incoming telnet/rlogin/ssh connections and/or
serve several X terminals may want to increase this: every incoming
connection and every xterm uses up one PTY.
When not in use, each additional set of 256 PTYs occupy
approximately 8 KB of kernel memory on 32-bit architectures.
