2) ARCH_DMA_MINALIGN
Architectures must ensure that kmalloc'ed buffer is
DMA-safe. Drivers and subsystems depend on it. If an architecture
isn't fully DMA-coherent (i.e. hardware doesn't ensure that data in
the CPU cache is identical to data in main memory),
ARCH_KMALLOC_MINALIGN must be set so that the memory allocator
ARCH_DMA_MINALIGN must be set so that the memory allocator
makes sure that kmalloc'ed buffer doesn't share a cache line with
the others. See arch/arm/include/asm/cache.h as an example.
Note that ARCH_KMALLOC_MINALIGN is about DMA memory alignment
Note that ARCH_DMA_MINALIGN is about DMA memory alignment
constraints. You don't need to worry about the architecture data
alignment constraints (e.g. the alignment constraints about 64-bit
objects).
3) Supporting multiple types of IOMMUs
If your architecture needs to support multiple types of IOMMUs, you
can use include/linux/asm-generic/dma-mapping-common.h. It's a
library to support the DMA API with multiple types of IOMMUs. Lots
of architectures (x86, powerpc, sh, alpha, ia64, microblaze and
sparc) use it. Choose one to see how it can be used. If you need to
support multiple types of IOMMUs in a single system, the example of
x86 or powerpc helps.

deliberate; as soon as struct block_device * is propagated in a reasonable
way by that code fixing will become trivial; until then nothing can be
done.
[mandatory]
block truncatation on error exit from ->write_begin, and ->direct_IO
moved from generic methods (block_write_begin, cont_write_begin,
nobh_write_begin, blockdev_direct_IO*) to callers. Take a look at
ext2_write_failed and callers for an example.
[mandatory]
->truncate is going away. The whole truncate sequence needs to be
implemented in ->setattr, which is now mandatory for filesystems
implementing on-disk size changes. Start with a copy of the old inode_setattr
and vmtruncate, and the reorder the vmtruncate + foofs_vmtruncate sequence to
be in order of zeroing blocks using block_truncate_page or similar helpers,
size update and on finally on-disk truncation which should not fail.
inode_change_ok now includes the size checks for ATTR_SIZE and must be called
in the beginning of ->setattr unconditionally.
[mandatory]
->clear_inode() and ->delete_inode() are gone; ->evict_inode() should
be used instead. It gets called whenever the inode is evicted, whether it has
remaining links or not. Caller does *not* evict the pagecache or inode-associated
metadata buffers; getting rid of those is responsibility of method, as it had
been for ->delete_inode().
->drop_inode() returns int now; it's called on final iput() with inode_lock
held and it returns true if filesystems wants the inode to be dropped. As before,
generic_drop_inode() is still the default and it's been updated appropriately.
generic_delete_inode() is also alive and it consists simply of return 1. Note that
all actual eviction work is done by caller after ->drop_inode() returns.
clear_inode() is gone; use end_writeback() instead. As before, it must
be called exactly once on each call of ->evict_inode() (as it used to be for
each call of ->delete_inode()). Unlike before, if you are using inode-associated
metadata buffers (i.e. mark_buffer_dirty_inode()), it's your responsibility to
call invalidate_inode_buffers() before end_writeback().
No async writeback (and thus no calls of ->write_inode()) will happen
after end_writeback() returns, so actions that should not overlap with ->write_inode()
(e.g. freeing on-disk inode if i_nlink is 0) ought to be done after that call.
NOTE: checking i_nlink in the beginning of ->write_inode() and bailing out
if it's zero is not *and* *never* *had* *been* enough. Final unlink() and iput()
may happen while the inode is in the middle of ->write_inode(); e.g. if you blindly
free the on-disk inode, you may end up doing that while ->write_inode() is writing
to it.

Kernel driver emc2103
======================
Supported chips:
* SMSC EMC2103
Addresses scanned: I2C 0x2e
Prefix: 'emc2103'
Datasheet: Not public
Authors:
Steve Glendinning <steve.glendinning@smsc.com>
Description
-----------
The Standard Microsystems Corporation (SMSC) EMC2103 chips
contain up to 4 temperature sensors and a single fan controller.
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. Fan
readings can be divided by a programmable divider (1, 2, 4 or 8) to give
the readings more range or accuracy. Not all RPM values can accurately be
represented, so some rounding is done. With a divider of 1, the lowest
representable value is 480 RPM.
This driver supports RPM based control, to use this a fan target
should be written to fan1_target and pwm1_enable should be set to 3.
The 2103-2 and 2103-4 variants have a third temperature sensor, which can
be connected to two anti-parallel diodes. These values can be read
as temp3 and temp4. If only one diode is attached to this channel, temp4
will show as "fault". The module parameter "apd=0" can be used to suppress
this 4th channel when anti-parallel diodes are not fitted.

------
If you have NOT configured the driver to sample all GPIO pins as analog
voltages, then the in10_input and in11_input sysfs attributes will not be
created. The driver will sample the GPIO pin that is currently connected to the
ADC as an analog voltage, and report the value in in9_input.
If you have configured the driver to sample all GPIO pins as analog voltages,
then they will be sampled in round-robin fashion. If userspace reads too
slowly, -EAGAIN will be returned when you read the sysfs attribute containing
the sensor reading.
The LTC4245 chip can be configured to sample all GPIO pins with two methods:
1) platform data -- see include/linux/i2c/ltc4245.h
2) OF device tree -- add the "ltc4245,use-extra-gpios" property to each chip
The default mode of operation is to sample a single GPIO pin.

An alarm is triggered if the rotation speed drops below a programmable

Fan Speed Control
-----------------
Fan speed can be controlled by PWM outputs. There are 4 possible modes:
always off, always on, manual and automatic. The latter isn't supported
by the driver: you can only return to that mode if it was the original
setting, and the configuration interface is missing.
Temperature Monitoring

The PC87427 relies on external sensors (following the SensorPath
standard), so the resolution and range depend on the type of sensor

not. I couldn't find a way to figure out the external sensor data
temperature format, so user-space adjustment (typically by a factor 2)
may be required.

oemid OEM/Application ID (from CID Register)
serial Product Serial Number (from CID Register)
erase_size Erase group size
preferred_erase_size Preferred erase size
Note on Erase Size and Preferred Erase Size:
"erase_size" is the minimum size, in bytes, of an erase
operation. For MMC, "erase_size" is the erase group size
reported by the card. Note that "erase_size" does not apply
to trim or secure trim operations where the minimum size is
always one 512 byte sector. For SD, "erase_size" is 512
if the card is block-addressed, 0 otherwise.
SD/MMC cards can erase an arbitrarily large area up to and
including the whole card. When erasing a large area it may
be desirable to do it in smaller chunks for three reasons:
1. A single erase command will make all other I/O on
the card wait. This is not a problem if the whole card
is being erased, but erasing one partition will make
I/O for another partition on the same card wait for the
duration of the erase - which could be a several
minutes.
2. To be able to inform the user of erase progress.
3. The erase timeout becomes too large to be very
useful. Because the erase timeout contains a margin
which is multiplied by the size of the erase area,
the value can end up being several minutes for large
areas.
"erase_size" is not the most efficient unit to erase
(especially for SD where it is just one sector),
hence "preferred_erase_size" provides a good chunk
size for erasing large areas.
For MMC, "preferred_erase_size" is the high-capacity
erase size if a card specifies one, otherwise it is
based on the capacity of the card.
For SD, "preferred_erase_size" is the allocation unit
size specified by the card.
"preferred_erase_size" is in bytes.

The Wavelan drivers saga
------------------------
By Jean Tourrilhes <jt@hpl.hp.com>
The Wavelan is a Radio network adapter designed by
Lucent. Under this generic name is hidden quite a variety of hardware,
and many Linux driver to support it.
The get the full story on Wireless LANs, please consult :
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
"wavelan" driver (old ISA Wavelan)
----------------
o Config : Network device -> Wireless LAN -> AT&T WaveLAN
o Location : .../drivers/net/wireless/wavelan*
o in-line doc : .../drivers/net/wireless/wavelan.p.h
o on-line doc :
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
This is the driver for the ISA version of the first generation
of the Wavelan, now discontinued. The device is 2 Mb/s, composed of a
Intel 82586 controller and a Lucent Modem, and is NOT 802.11 compliant.
The driver has been tested with the following hardware :
o Wavelan ISA 915 MHz (full length ISA card)
o Wavelan ISA 915 MHz 2.0 (half length ISA card)
o Wavelan ISA 2.4 GHz (full length ISA card, fixed frequency)
o Wavelan ISA 2.4 GHz 2.0 (half length ISA card, frequency selectable)
o Above cards with the optional DES encryption feature
"wavelan_cs" driver (old Pcmcia Wavelan)
-------------------
o Config : Network device -> PCMCIA network ->
Pcmcia Wireless LAN -> AT&T/Lucent WaveLAN
o Location : .../drivers/net/pcmcia/wavelan*
o in-line doc : .../drivers/net/pcmcia/wavelan_cs.h
o on-line doc :
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
This is the driver for the PCMCIA version of the first
generation of the Wavelan, now discontinued. The device is 2 Mb/s,
composed of a Intel 82593 controller (totally different from the 82586)
and a Lucent Modem, and NOT 802.11 compatible.
The driver has been tested with the following hardware :
o Wavelan Pcmcia 915 MHz 2.0 (Pcmcia card + separate
modem/antenna block)
o Wavelan Pcmcia 2.4 GHz 2.0 (Pcmcia card + separate
modem/antenna block)
"wvlan_cs" driver (Wavelan IEEE, GPL)
-----------------
o Config : Not yet in kernel
o Location : Pcmcia package 3.1.10+
o on-line doc :
http://web.archive.org/web/*/http://www.fasta.fh-dortmund.de/users/andy/wvlan/
This is the driver for the current generation of Wavelan IEEE,
which is 802.11 compatible. Depending on version, it is 2 Mb/s or 11
Mb/s, with or without encryption, all implemented in Lucent specific
DSP (the Hermes).
This is a GPL full source PCMCIA driver (ISA is just a Pcmcia
card with ISA-Pcmcia bridge).
"wavelan2_cs" driver (Wavelan IEEE, binary)
--------------------
o Config : Not yet in kernel
o Location : ftp://sourceforge.org/pcmcia/contrib/
This driver support exactly the same hardware as the previous
driver, the main difference is that it is based on a binary library
and supported by Lucent.
I hope it clears the confusion ;-)

~~~~~~~~~~~~~~~~~~~~~~
See Documentation/kernel-parameters.txt for general information on
specifying module parameters.
This document may not be entirely up to date and comprehensive. The command
"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
module. Loadable modules, after being loaded into the running kernel, also
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
parameters may be changed at runtime by the command
"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".

-*- org -*-
* Overview
The Multifunction Composite Gadget (or g_multi) is a composite gadget
that makes extensive use of the composite framework to provide
a... multifunction gadget.
In it's standard configuration it provides a single USB configuration
with RNDIS[1] (that is Ethernet), USB CDC[2] ACM (that is serial) and
USB Mass Storage functions.
A CDC ECM (Ethernet) function may be turned on via a Kconfig option
and RNDIS can be turned off. If they are both enabled the gadget will
have two configurations -- one with RNDIS and another with CDC ECM[3].
Please not that if you use non-standard configuration (that is enable
CDC ECM) you may need to change vendor and/or product ID.
* Host drivers
To make use of the gadget one needs to make it work on host side --
without that there's no hope of achieving anything with the gadget.
As one might expect, things one need to do very from system to system.
** Linux host drivers
Since the gadget uses standard composite framework and appears as such
to Linux host it does not need any additional drivers on Linux host
side. All the functions are handled by respective drivers developed
for them.
This is also true for two configuration set-up with RNDIS
configuration being the first one. Linux host will use the second
configuration with CDC ECM which should work better under Linux.
** Windows host drivers
For the gadget two work under Windows two conditions have to be met:
*** Detecting as composite gadget
First of all, Windows need to detect the gadget as an USB composite
gadget which on its own have some conditions[4]. If they are met,
Windows lets USB Generic Parent Driver[5] handle the device which then
tries to much drivers for each individual interface (sort of, don't
get into too many details).
The good news is: you do not have to worry about most of the
conditions!
The only thing to worry is that the gadget has to have a single
configuration so a dual RNDIS and CDC ECM gadget won't work unless you
create a proper INF -- and of course, if you do submit it!
*** Installing drivers for each function
The other, trickier thing is making Windows install drivers for each
individual function.
For mass storage it is trivial since Windows detect it's an interface
implementing USB Mass Storage class and selects appropriate driver.
Things are harder with RDNIS and CDC ACM.
**** RNDIS
To make Windows select RNDIS drivers for the first function in the
gadget, one needs to use the [[file:linux.inf]] file provided with this
document. It "attaches" Window's RNDIS driver to the first interface
of the gadget.
Please note, that while testing we encountered some issues[6] when
RNDIS was not the first interface. You do not need to worry abut it
unless you are trying to develop your own gadget in which case watch
out for this bug.
**** CDC ACM
Similarly, [[file:linux-cdc-acm.inf]] is provided for CDC ACM.
**** Customising the gadget
If you intend to hack the g_multi gadget be advised that rearranging
functions will obviously change interface numbers for each of the
functionality. As an effect provided INFs won't work since they have
interface numbers hard-coded in them (it's not hard to change those
though[7]).
This also means, that after experimenting with g_multi and changing
provided functions one should change gadget's vendor and/or product ID
so there will be no collision with other customised gadgets or the
original gadget.
Failing to comply may cause brain damage after wondering for hours why
things don't work as intended before realising Windows have cached
some drivers information (changing USB port may sometimes help plus
you might try using USBDeview[8] to remove the phantom device).
**** INF testing
Provided INF files have been tested on Windows XP SP3, Windows Vista
and Windows 7, all 32-bit versions. It should work on 64-bit versions
as well. It most likely won't work on Windows prior to Windows XP
SP2.
** Other systems
At this moment, drivers for any other systems have not been tested.
Knowing how MacOS is based on BSD and BSD is an Open Source it is
believed that it should (read: "I have no idea whether it will") work
out-of-the-box.
For more exotic systems I have even less to say...
Any testing and drivers *are* *welcome*!

([[mailto:mina86@mina86.com]]). INF files have been hacked with
support of Marek Szyprowski ([[mailto:m.szyprowski@samsung.com]]) and
Xiaofan Chen ([[mailto:xiaofanc@gmail.com]]) basing on the MS RNDIS
template[9], Microchip's CDC ACM INF file and David Brownell's

Introduction
============
The V4L2 control API seems simple enough, but quickly becomes very hard to
implement correctly in drivers. But much of the code needed to handle controls
is actually not driver specific and can be moved to the V4L core framework.
After all, the only part that a driver developer is interested in is:
1) How do I add a control?
2) How do I set the control's value? (i.e. s_ctrl)
And occasionally:
3) How do I get the control's value? (i.e. g_volatile_ctrl)
4) How do I validate the user's proposed control value? (i.e. try_ctrl)
All the rest is something that can be done centrally.
The control framework was created in order to implement all the rules of the
V4L2 specification with respect to controls in a central place. And to make
life as easy as possible for the driver developer.
Note that the control framework relies on the presence of a struct v4l2_device
for V4L2 drivers and struct v4l2_subdev for sub-device drivers.
Objects in the framework
========================
There are two main objects:
The v4l2_ctrl object describes the control properties and keeps track of the
control's value (both the current value and the proposed new value).
v4l2_ctrl_handler is the object that keeps track of controls. It maintains a
list of v4l2_ctrl objects that it owns and another list of references to
controls, possibly to controls owned by other handlers.
Basic usage for V4L2 and sub-device drivers
===========================================
1) Prepare the driver:
1.1) Add the handler to your driver's top-level struct:
struct foo_dev {
...
struct v4l2_ctrl_handler ctrl_handler;
...
};
struct foo_dev *foo;
1.2) Initialize the handler:
v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
The second argument is a hint telling the function how many controls this
handler is expected to handle. It will allocate a hashtable based on this
information. It is a hint only.
1.3) Hook the control handler into the driver:
1.3.1) For V4L2 drivers do this:
struct foo_dev {
...
struct v4l2_device v4l2_dev;
...
struct v4l2_ctrl_handler ctrl_handler;
...
};
foo->v4l2_dev.ctrl_handler = &foo->ctrl_handler;
Where foo->v4l2_dev is of type struct v4l2_device.
Finally, remove all control functions from your v4l2_ioctl_ops:
vidioc_queryctrl, vidioc_querymenu, vidioc_g_ctrl, vidioc_s_ctrl,
vidioc_g_ext_ctrls, vidioc_try_ext_ctrls and vidioc_s_ext_ctrls.
Those are now no longer needed.
1.3.2) For sub-device drivers do this:
struct foo_dev {
...
struct v4l2_subdev sd;
...
struct v4l2_ctrl_handler ctrl_handler;
...
};
foo->sd.ctrl_handler = &foo->ctrl_handler;
Where foo->sd is of type struct v4l2_subdev.
And set all core control ops in your struct v4l2_subdev_core_ops to these
helpers:
.queryctrl = v4l2_subdev_queryctrl,
.querymenu = v4l2_subdev_querymenu,
.g_ctrl = v4l2_subdev_g_ctrl,
.s_ctrl = v4l2_subdev_s_ctrl,
.g_ext_ctrls = v4l2_subdev_g_ext_ctrls,
.try_ext_ctrls = v4l2_subdev_try_ext_ctrls,
.s_ext_ctrls = v4l2_subdev_s_ext_ctrls,
Note: this is a temporary solution only. Once all V4L2 drivers that depend
on subdev drivers are converted to the control framework these helpers will
no longer be needed.
1.4) Clean up the handler at the end:
v4l2_ctrl_handler_free(&foo->ctrl_handler);
2) Add controls:
You add non-menu controls by calling v4l2_ctrl_new_std:
struct v4l2_ctrl *v4l2_ctrl_new_std(struct v4l2_ctrl_handler *hdl,
const struct v4l2_ctrl_ops *ops,
u32 id, s32 min, s32 max, u32 step, s32 def);
Menu controls are added by calling v4l2_ctrl_new_std_menu:
struct v4l2_ctrl *v4l2_ctrl_new_std_menu(struct v4l2_ctrl_handler *hdl,
const struct v4l2_ctrl_ops *ops,
u32 id, s32 max, s32 skip_mask, s32 def);
These functions are typically called right after the v4l2_ctrl_handler_init:
v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
V4L2_CID_BRIGHTNESS, 0, 255, 1, 128);
v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
V4L2_CID_CONTRAST, 0, 255, 1, 128);
v4l2_ctrl_new_std_menu(&foo->ctrl_handler, &foo_ctrl_ops,
V4L2_CID_POWER_LINE_FREQUENCY,
V4L2_CID_POWER_LINE_FREQUENCY_60HZ, 0,
V4L2_CID_POWER_LINE_FREQUENCY_DISABLED);
...
if (foo->ctrl_handler.error) {
int err = foo->ctrl_handler.error;
v4l2_ctrl_handler_free(&foo->ctrl_handler);
return err;
}
The v4l2_ctrl_new_std function returns the v4l2_ctrl pointer to the new
control, but if you do not need to access the pointer outside the control ops,
then there is no need to store it.
The v4l2_ctrl_new_std function will fill in most fields based on the control
ID except for the min, max, step and default values. These are passed in the
last four arguments. These values are driver specific while control attributes
like type, name, flags are all global. The control's current value will be set
to the default value.
The v4l2_ctrl_new_std_menu function is very similar but it is used for menu
controls. There is no min argument since that is always 0 for menu controls,
and instead of a step there is a skip_mask argument: if bit X is 1, then menu
item X is skipped.
Note that if something fails, the function will return NULL or an error and
set ctrl_handler->error to the error code. If ctrl_handler->error was already
set, then it will just return and do nothing. This is also true for
v4l2_ctrl_handler_init if it cannot allocate the internal data structure.
This makes it easy to init the handler and just add all controls and only check
the error code at the end. Saves a lot of repetitive error checking.
It is recommended to add controls in ascending control ID order: it will be
a bit faster that way.
3) Optionally force initial control setup:
v4l2_ctrl_handler_setup(&foo->ctrl_handler);
This will call s_ctrl for all controls unconditionally. Effectively this
initializes the hardware to the default control values. It is recommended
that you do this as this ensures that both the internal data structures and
the hardware are in sync.
4) Finally: implement the v4l2_ctrl_ops
static const struct v4l2_ctrl_ops foo_ctrl_ops = {
.s_ctrl = foo_s_ctrl,
};
Usually all you need is s_ctrl:
static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
{
struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
switch (ctrl->id) {
case V4L2_CID_BRIGHTNESS:
write_reg(0x123, ctrl->val);
break;
case V4L2_CID_CONTRAST:
write_reg(0x456, ctrl->val);
break;
}
return 0;
}
The control ops are called with the v4l2_ctrl pointer as argument.
The new control value has already been validated, so all you need to do is
to actually update the hardware registers.
You're done! And this is sufficient for most of the drivers we have. No need
to do any validation of control values, or implement QUERYCTRL/QUERYMENU. And
G/S_CTRL as well as G/TRY/S_EXT_CTRLS are automatically supported.
==============================================================================
The remainder of this document deals with more advanced topics and scenarios.
In practice the basic usage as described above is sufficient for most drivers.
===============================================================================
Inheriting Controls
===================
When a sub-device is registered with a V4L2 driver by calling
v4l2_device_register_subdev() and the ctrl_handler fields of both v4l2_subdev
and v4l2_device are set, then the controls of the subdev will become
automatically available in the V4L2 driver as well. If the subdev driver
contains controls that already exist in the V4L2 driver, then those will be
skipped (so a V4L2 driver can always override a subdev control).
What happens here is that v4l2_device_register_subdev() calls
v4l2_ctrl_add_handler() adding the controls of the subdev to the controls
of v4l2_device.
Accessing Control Values
========================
The v4l2_ctrl struct contains these two unions:
/* The current control value. */
union {
s32 val;
s64 val64;
char *string;
} cur;
/* The new control value. */
union {
s32 val;
s64 val64;
char *string;
};
Within the control ops you can freely use these. The val and val64 speak for
themselves. The string pointers point to character buffers of length
ctrl->maximum + 1, and are always 0-terminated.
In most cases 'cur' contains the current cached control value. When you create
a new control this value is made identical to the default value. After calling
v4l2_ctrl_handler_setup() this value is passed to the hardware. It is generally
a good idea to call this function.
Whenever a new value is set that new value is automatically cached. This means
that most drivers do not need to implement the g_volatile_ctrl() op. The
exception is for controls that return a volatile register such as a signal
strength read-out that changes continuously. In that case you will need to
implement g_volatile_ctrl like this:
static int foo_g_volatile_ctrl(struct v4l2_ctrl *ctrl)
{
switch (ctrl->id) {
case V4L2_CID_BRIGHTNESS:
ctrl->cur.val = read_reg(0x123);
break;
}
}
The 'new value' union is not used in g_volatile_ctrl. In general controls
that need to implement g_volatile_ctrl are read-only controls.
To mark a control as volatile you have to set the is_volatile flag:
ctrl = v4l2_ctrl_new_std(&sd->ctrl_handler, ...);
if (ctrl)
ctrl->is_volatile = 1;
For try/s_ctrl the new values (i.e. as passed by the user) are filled in and
you can modify them in try_ctrl or set them in s_ctrl. The 'cur' union
contains the current value, which you can use (but not change!) as well.
If s_ctrl returns 0 (OK), then the control framework will copy the new final
values to the 'cur' union.
While in g_volatile/s/try_ctrl you can access the value of all controls owned
by the same handler since the handler's lock is held. If you need to access
the value of controls owned by other handlers, then you have to be very careful
not to introduce deadlocks.
Outside of the control ops you have to go through to helper functions to get
or set a single control value safely in your driver:
s32 v4l2_ctrl_g_ctrl(struct v4l2_ctrl *ctrl);
int v4l2_ctrl_s_ctrl(struct v4l2_ctrl *ctrl, s32 val);
These functions go through the control framework just as VIDIOC_G/S_CTRL ioctls
do. Don't use these inside the control ops g_volatile/s/try_ctrl, though, that
will result in a deadlock since these helpers lock the handler as well.
You can also take the handler lock yourself:
mutex_lock(&state->ctrl_handler.lock);
printk(KERN_INFO "String value is '%s'\n", ctrl1->cur.string);
printk(KERN_INFO "Integer value is '%s'\n", ctrl2->cur.val);
mutex_unlock(&state->ctrl_handler.lock);
Menu Controls
=============
The v4l2_ctrl struct contains this union:
union {
u32 step;
u32 menu_skip_mask;
};
For menu controls menu_skip_mask is used. What it does is that it allows you
to easily exclude certain menu items. This is used in the VIDIOC_QUERYMENU
implementation where you can return -EINVAL if a certain menu item is not
present. Note that VIDIOC_QUERYCTRL always returns a step value of 1 for
menu controls.
A good example is the MPEG Audio Layer II Bitrate menu control where the
menu is a list of standardized possible bitrates. But in practice hardware
implementations will only support a subset of those. By setting the skip
mask you can tell the framework which menu items should be skipped. Setting
it to 0 means that all menu items are supported.
You set this mask either through the v4l2_ctrl_config struct for a custom
control, or by calling v4l2_ctrl_new_std_menu().
Custom Controls
===============
Driver specific controls can be created using v4l2_ctrl_new_custom():
static const struct v4l2_ctrl_config ctrl_filter = {
.ops = &ctrl_custom_ops,
.id = V4L2_CID_MPEG_CX2341X_VIDEO_SPATIAL_FILTER,
.name = "Spatial Filter",
.type = V4L2_CTRL_TYPE_INTEGER,
.flags = V4L2_CTRL_FLAG_SLIDER,
.max = 15,
.step = 1,
};
ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_filter, NULL);
The last argument is the priv pointer which can be set to driver-specific
private data.
The v4l2_ctrl_config struct also has fields to set the is_private and is_volatile
flags.
If the name field is not set, then the framework will assume this is a standard
control and will fill in the name, type and flags fields accordingly.
Active and Grabbed Controls
===========================
If you get more complex relationships between controls, then you may have to
activate and deactivate controls. For example, if the Chroma AGC control is
on, then the Chroma Gain control is inactive. That is, you may set it, but
the value will not be used by the hardware as long as the automatic gain
control is on. Typically user interfaces can disable such input fields.
You can set the 'active' status using v4l2_ctrl_activate(). By default all
controls are active. Note that the framework does not check for this flag.
It is meant purely for GUIs. The function is typically called from within
s_ctrl.
The other flag is the 'grabbed' flag. A grabbed control means that you cannot
change it because it is in use by some resource. Typical examples are MPEG
bitrate controls that cannot be changed while capturing is in progress.
If a control is set to 'grabbed' using v4l2_ctrl_grab(), then the framework
will return -EBUSY if an attempt is made to set this control. The
v4l2_ctrl_grab() function is typically called from the driver when it
starts or stops streaming.
Control Clusters
================
By default all controls are independent from the others. But in more
complex scenarios you can get dependencies from one control to another.
In that case you need to 'cluster' them:
struct foo {
struct v4l2_ctrl_handler ctrl_handler;
#define AUDIO_CL_VOLUME (0)
#define AUDIO_CL_MUTE (1)
struct v4l2_ctrl *audio_cluster[2];
...
};
state->audio_cluster[AUDIO_CL_VOLUME] =
v4l2_ctrl_new_std(&state->ctrl_handler, ...);
state->audio_cluster[AUDIO_CL_MUTE] =
v4l2_ctrl_new_std(&state->ctrl_handler, ...);
v4l2_ctrl_cluster(ARRAY_SIZE(state->audio_cluster), state->audio_cluster);
From now on whenever one or more of the controls belonging to the same
cluster is set (or 'gotten', or 'tried'), only the control ops of the first
control ('volume' in this example) is called. You effectively create a new
composite control. Similar to how a 'struct' works in C.
So when s_ctrl is called with V4L2_CID_AUDIO_VOLUME as argument, you should set
all two controls belonging to the audio_cluster:
static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
{
struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
switch (ctrl->id) {
case V4L2_CID_AUDIO_VOLUME: {
struct v4l2_ctrl *mute = ctrl->cluster[AUDIO_CL_MUTE];
write_reg(0x123, mute->val ? 0 : ctrl->val);
break;
}
case V4L2_CID_CONTRAST:
write_reg(0x456, ctrl->val);
break;
}
return 0;
}
In the example above the following are equivalent for the VOLUME case:
ctrl == ctrl->cluster[AUDIO_CL_VOLUME] == state->audio_cluster[AUDIO_CL_VOLUME]
ctrl->cluster[AUDIO_CL_MUTE] == state->audio_cluster[AUDIO_CL_MUTE]
Note that controls in a cluster may be NULL. For example, if for some
reason mute was never added (because the hardware doesn't support that
particular feature), then mute will be NULL. So in that case we have a
cluster of 2 controls, of which only 1 is actually instantiated. The
only restriction is that the first control of the cluster must always be
present, since that is the 'master' control of the cluster. The master
control is the one that identifies the cluster and that provides the
pointer to the v4l2_ctrl_ops struct that is used for that cluster.
Obviously, all controls in the cluster array must be initialized to either
a valid control or to NULL.
VIDIOC_LOG_STATUS Support
=========================
This ioctl allow you to dump the current status of a driver to the kernel log.
The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the
value of the controls owned by the given handler to the log. You can supply a
prefix as well. If the prefix didn't end with a space, then ': ' will be added
for you.
Different Handlers for Different Video Nodes
============================================
Usually the V4L2 driver has just one control handler that is global for
all video nodes. But you can also specify different control handlers for
different video nodes. You can do that by manually setting the ctrl_handler
field of struct video_device.
That is no problem if there are no subdevs involved but if there are, then
you need to block the automatic merging of subdev controls to the global
control handler. You do that by simply setting the ctrl_handler field in
struct v4l2_device to NULL. Now v4l2_device_register_subdev() will no longer
merge subdev controls.
After each subdev was added, you will then have to call v4l2_ctrl_add_handler
manually to add the subdev's control handler (sd->ctrl_handler) to the desired
control handler. This control handler may be specific to the video_device or
for a subset of video_device's. For example: the radio device nodes only have
audio controls, while the video and vbi device nodes share the same control
handler for the audio and video controls.
If you want to have one handler (e.g. for a radio device node) have a subset
of another handler (e.g. for a video device node), then you should first add
the controls to the first handler, add the other controls to the second
handler and finally add the first handler to the second. For example:
v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_VOLUME, ...);
v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler);
Or you can add specific controls to a handler:
volume = v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_AUDIO_VOLUME, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_BRIGHTNESS, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_CONTRAST, ...);
v4l2_ctrl_add_ctrl(&radio_ctrl_handler, volume);
What you should not do is make two identical controls for two handlers.
For example:
v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_AUDIO_MUTE, ...);
This would be bad since muting the radio would not change the video mute
control. The rule is to have one control for each hardware 'knob' that you
can twiddle.
Finding Controls
================
Normally you have created the controls yourself and you can store the struct
v4l2_ctrl pointer into your own struct.
But sometimes you need to find a control from another handler that you do
not own. For example, if you have to find a volume control from a subdev.
You can do that by calling v4l2_ctrl_find:
struct v4l2_ctrl *volume;
volume = v4l2_ctrl_find(sd->ctrl_handler, V4L2_CID_AUDIO_VOLUME);
Since v4l2_ctrl_find will lock the handler you have to be careful where you
use it. For example, this is not a good idea:
struct v4l2_ctrl_handler ctrl_handler;
v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
...and in video_ops.s_ctrl:
case V4L2_CID_BRIGHTNESS:
contrast = v4l2_find_ctrl(&ctrl_handler, V4L2_CID_CONTRAST);
...
When s_ctrl is called by the framework the ctrl_handler.lock is already taken, so
attempting to find another control from the same handler will deadlock.
It is recommended not to use this function from inside the control ops.
Inheriting Controls
===================
When one control handler is added to another using v4l2_ctrl_add_handler, then
by default all controls from one are merged to the other. But a subdev might
have low-level controls that make sense for some advanced embedded system, but
not when it is used in consumer-level hardware. In that case you want to keep
those low-level controls local to the subdev. You can do this by simply
setting the 'is_private' flag of the control to 1:
static const struct v4l2_ctrl_config ctrl_private = {
.ops = &ctrl_custom_ops,
.id = V4L2_CID_...,
.name = "Some Private Control",
.type = V4L2_CTRL_TYPE_INTEGER,
.max = 15,
.step = 1,
.is_private = 1,
};
ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_private, NULL);
These controls will now be skipped when v4l2_ctrl_add_handler is called.
V4L2_CTRL_TYPE_CTRL_CLASS Controls
==================================
Controls of this type can be used by GUIs to get the name of the control class.
A fully featured GUI can make a dialog with multiple tabs with each tab
containing the controls belonging to a particular control class. The name of
each tab can be found by querying a special control with ID <control class | 1>.
Drivers do not have to care about this. The framework will automatically add
a control of this type whenever the first control belonging to a new control
class is added.
Differences from the Spec
=========================
There are a few places where the framework acts slightly differently from the
V4L2 Specification. Those differences are described in this section. We will
have to see whether we need to adjust the spec or not.
1) It is no longer required to have all controls contained in a
v4l2_ext_control array be from the same control class. The framework will be
able to handle any type of control in the array. You need to set ctrl_class
to 0 in order to enable this. If ctrl_class is non-zero, then it will still
check that all controls belong to that control class.
If you set ctrl_class to 0 and count to 0, then it will only return an error
if there are no controls at all.
2) Clarified the way error_idx works. For get and set it will be equal to
count if nothing was done yet. If it is less than count then only the controls
up to error_idx-1 were successfully applied.
3) When attempting to read a button control the framework will return -EACCES
instead of -EINVAL as stated in the spec. It seems to make more sense since
button controls are write-only controls.
4) Attempting to write to a read-only control will return -EACCES instead of
-EINVAL as the spec says.
5) The spec does not mention what should happen when you try to set/get a
control class controls. ivtv currently returns -EINVAL (indicating that the
control ID does not exist) while the framework will return -EACCES, which
makes more sense.
Proposals for Extensions
========================
Some ideas for future extensions to the spec:
1) Add a V4L2_CTRL_FLAG_HEX to have values shown as hexadecimal instead of
decimal. Useful for e.g. video_mute_yuv.
2) It is possible to mark in the controls array which controls have been
successfully written and which failed by for example adding a bit to the
control ID. Not sure if it is worth the effort, though.
3) Trying to set volatile inactive controls should result in -EACCESS.
4) Add a new flag to mark volatile controls. Any application that wants
to store the state of the controls can then skip volatile inactive controls.
Currently it is not possible to detect such controls.

bool "ARM errata: TLBIASIDIS and TLBIMVAIS operations can broadcast a faulty ASID"

help
This option enables the workaround for the 720789 Cortex-A9 (prior to
r2p0) erratum. A faulty ASID can be sent to the other CPUs for the
broadcasted CP15 TLB maintenance operations TLBIASIDIS and TLBIMVAIS.
As a consequence of this erratum, some TLB entries which should be
invalidated are not, resulting in an incoherency in the system page
tables. The workaround changes the TLB flushing routines to invalidate
entries regardless of the ASID.

/*
* When compiling with -pg, gcc inserts a call to the mcount routine at the
* start of every function. In mcount, apart from the function's address (in
* lr), we need to get hold of the function's caller's address.
*
* Older GCCs (pre-4.4) inserted a call to a routine called mcount like this:
*
* bl mcount
*
* These versions have the limitation that in order for the mcount routine to
* be able to determine the function's caller's address, an APCS-style frame
* pointer (which is set up with something like the code below) is required.
*
* mov ip, sp
* push {fp, ip, lr, pc}
* sub fp, ip, #4
*
* With EABI, these frame pointers are not available unless -mapcs-frame is
* specified, and if building as Thumb-2, not even then.
*
* Newer GCCs (4.4+) solve this problem by introducing a new version of mcount,
* with call sites like:
*
* push {lr}
* bl __gnu_mcount_nc
*
* With these compilers, frame pointers are not necessary.
*
* mcount can be thought of as a function called in the middle of a subroutine
* call. As such, it needs to be transparent for both the caller and the
* callee: the original lr needs to be restored when leaving mcount, and no
* registers should be clobbered. (In the __gnu_mcount_nc implementation, we
* clobber the ip register. This is OK because the ARM calling convention
* allows it to be clobbered in subroutines and doesn't use it to hold
* parameters.)
