2ce55b606b V4L/DVB (6053): ivtv: setup TV output standard on init to prevent flicker
The TV output standard was set only on first use, which meant that the saa7127
was set to NTSC until then, leading to flickering on PAL systems.

Since the saa7127 has no firmware it is OK to initialize it immediately.

- Invalid VBI packets should result in an empty VBI frame, not

- PIO completion should not reset the sg_pending_size field.

37093b1ea6 V4L/DVB (6047): ivtv: Fix scatter/gather DMA timeouts
It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA
reliably. Every so often depending on the phase of the moon and your
hardware configuration the cx2341x DMA engine simply chokes on it and
you have to reboot to get it working again.

This change replaced the scatter/gather DMA by single transfers at a time,
where the driver is now responsible for DMA-ing each buffer.

UDMA is still done using scatter/gather DMA, that will be fixed soon.

Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering
the link between scatter/gather and the DMA timeouts.

f4071b85ea V4L/DVB (6046): ivtv: always steal full frames if out of buffers.
When there are no more free buffers, then buffers are stolen from the
predma queue. Buffers should be stolen from the head of that queue (which
is where the most recently added buffers are) and all buffers belonging
to a frame should be stolen. Otherwise 'half-frames' would remain in the
queue, which leads to ugly playback and complete sync failure for YUV
buffers.

The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling,
otherwise the computer can freeze or the top-third of the screen can start

In addition the stop capture handling was improved so that the last pending
DMA transfer is also processed. Otherwise this would be the first data that
arrived when a new capture was started which is not what you want.

fa40b2237a V4L/DVB (6034): cx88: Add parameter to control radio deemphasis time constant
FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise.  The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.

However, the "no deemphasis" setting doesn't work.  On my chip, cx23883, it
produces the same result as the 75 us time constant.  Maybe the default
settings on the cx23881 are for 50 us?

Since the deemphasis time constant varies by country, allow setting it via a
module parameter.

5772f81326 V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s
Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

bbc83597df V4L/DVB (6022): cx88: Move card core creation from cx88-core.c to cx88-cards.c
A lot of code in cx88-cards.c was only used by cx88-core.c when the core state
is first allocated and initialized.  Moving that task to cx88-cards makes the
driver simpler and the files more self contained.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

6a59d64c5c V4L/DVB (6021): cx88: Copy board information into card state
The cx88 driver state stored the ID of the board type in core->board.  Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.

This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information.  This allows
access to board information without the extra indirection.  e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.

This has a number of advantages:
- The code is simpler to write.

- It compiles to be smaller and faster, without needing the extra array lookup
  to get at the board information.

- The cx88_boards array no longer needs to be exported to all cx88 modules.

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around
  after the module is loaded.

- If module parameters or eeprom info override some board configuration
  setting, it's not necessary to modify the boards array, which would
  affect all boards of the same type.

87410dab12 V4L/DVB (5997): cx25840: fix audio mute handling and reporting
Audio muting for the tuner input was implemented by stopping the 
audio microcontroller and restarting it on unmute. However, it 
appears that this method can actually crash the audio firmware. 
It's rare and seems to happen with NTSC only.

It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

5e082f1521 V4L/DVB (5978): tuner: Better tuner radio support
Add radio support for the Thomson DTT7612 tuner.

This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).

Add a new tuner-simple parameter, radio_if.  It selects the 1st IF used for
radio reception.  The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.

The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.

The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.

Add some defines for tda9887 bits that control IF setting in radio mode.

Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.

Fix the way tda9887 radio options work.  The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags.  This means that
_all_ tuners would get the same settings.  If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting.  Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.

The PLL setting math is made a little more accurate.

And a grammar error in a printk is fixed.

switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.

So, in radio mode GPIO2 = 1 and GPIO7 = 0.

Add some comments about how the HD-3000's GPIOs are connected.

Also delete the lines setting unused gpio words to zero; it's not necessary as

This patch attaches the field order to the frame, so that any buffered frames

order is changed mid stream, the driver will ensure that the previous frame
is displayed for a minimum of 3 fields. These are the two original fields the
frame should have occupied, plus the one extra since the new frame still has
to wait for the correct field.

If the incoming frames are delivered too fast, exhausting the buffers, the
most recent frame already buffered will be discarded. Unfortunately, any
update request will also be discarded. If the new frame matches the size &
position of the now discarded frame, the yuv registers are not flagged for
update & will remain in their old state.

18b548ca58 V4L/DVB (5884): zr36067: clean up debug function
Debugging cleanups to the zr36067 driver:

* Use module_param_named() to declare the debug parameter, so we can
  use a single global variable to handle the debug level. This makes
  the driver a bit smaller (by 648 bytes on x86_64), thanks to one
  less level of indirection on every use.

* Change the debug parameter sysfs permissions, so that the debug
  level can be adjusted at runtime, as is done in many other
  media/video drivers.

* The debug level is between 0 and 5, not 0 and 4.

* Move the zr_debug export and dprintk macro definition to a header
  file so that we don't have to define them in each source file.

* Simplify a duplicate test on zr_debug.

Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.

Configuring the OLPC camera requires something over 150 register
writes.  Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake.  The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization.  Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.

The osprey eeprom routine wasn't run for the 440, add it.  It was also crap,
re-written to be better.

Add the Osprey 440 to the Bt878 ALSA driver's whitelist.  Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.

Setting the audio gain via ALSA isn't supported yet; a userspace tool that
programs the X9221 via i2c-dev must be used.

The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC
used, resulting in extremely garbled sound.  That is fixed in a followup

format id, the format list simply has a field with the proper bits to set.

Adds a bit of ifdef to make a driver without V4L1 support more possible.
Also create a macro for defining formats that handles vl41 and/or vl42
support to avoid repeated ifdefs in the format list.

bb2e033913 V4L/DVB (5888): zr36067: Driver was not returning correct image size
The driver was returning the size of the (fixed) buffer it allocated as the
sizeimage field in the v4l2 pixel format, rather than the actual size of the
image.  For example, a 192x128 YUYV image is 49152 bytes but the driver would
always return 131072 bytes since if that was the size of the v4l buffer.

This violates the v4l2 spec, which says that sizeimage should be the actual
size of the image for uncompressed formats.  It also caused mplayer to crash.

e42af83f48 V4L/DVB (5887): zr36067: Fix poll() operation
During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).

It also wasn't looking in the right spot.  It was looking at the file handle's
copy of the buffer status, rather than the driver core copy.  The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated.  So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.

The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.

There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea.  It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.

The buffer state variables are protected by a spin lock, which the code wasn't
acquiring.  That is fixed too.

c812b67ca4 V4L/DVB (5886): zr36067: Fix problem setting norms
The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms.  For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.

When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration.  If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail.  This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."

The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits.  It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.

This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.

The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

ac7dc84584 V4L/DVB (5805): Bttv: Fix problems with probing for non-existent tuners
The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver.  Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.

For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module.  That can
be skipped for cards that don't need it.  The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.

The tuner into printk()s are also made nicer.  Levels are added, INFO or
WARNING, depending on the meaning.  For cards with no tuner, or no tuner
defined, a more informative message is printed.

Card has no tuner, before patch:
bttv0: tuner type=-1
 or
bttv0: tuner type=4

After patch:

bttv0: tuner absent

Card has a tuner, but the type isn't defined, before patch:

- zr364xx checks video_register_device() error only when
  its return value is -1. But video_register_device() doesn't
  always return -1 on error.

- If usb_register() returns error, module_init() wrongly returns 1:
	retval = usb_register(&zr364xx_driver) < 0;
	...
	return retval;

  And it allows the module to be loaded. Because sys_init_module() doesn't
  see positive return value as error.

Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.

The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point.  This the recommended value for
DVB-T operation.

The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).

The existing dvb-pll users in the cx88 driver, listed below, will gain these

This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence.  The non-dvb-pll code for this
user is removed.

X88_BOARD_DNTV_LIVE_DVB_T_PRO   digitalnow DNTV Live! DVB-T Pro

In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:

SAA7134_BOARD_MD7134                    Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID       Asus Europa2 OEM

The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.

This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.

For the cxusb driver, only one board is effected:

USB_PID_MEDION_MD95700          	Medion MD95700

This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively.  These functions are effectively the same
as the dvb-pll versions.  They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does).  This board will gain
the sleep sequence, while init and tuning should be unchanged.

8314418629 Freezer: make kernel threads nonfreezable by default
Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

333408f215 V4L/DVB (5808): Bttv: fix v4l1 breaking the driver
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as
the first user after the driver is loaded, the driver wedges itself and will
never capture properly.  Even if one uses a V4L2 application later, it still
won't work.

If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2
driver, then the driver will be ok.  One can then run a V4L1 application, and
it will work.

It turns out the problem is with norm changing and the crop support that was
added in 2.6.21.  The driver defaults to PAL, and keeps the last norm it was
set too across opens.  If one changes the norm via V4L1, the cropping
parameters are not reset like they should be, and they'll remain broken across
device opens.

This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl
VIDIOCSCHAN handler.  The norm is set via the existing call to set_input(),
which calls set_tvnorm(), which will reset the cropping values now that it is
able to detect the norm change.

58e78475ec saa7134: fix thread shutdown handling
This patch changes the test for the thread pid from >= 0 to > 0.

When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver.  Part of shutting it
down includes tearing down the thread for tv audio.

The test for tearing down the thread tests for >= 0.  Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet.  We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

59faba1b31 Fix Kconfig dependency problems wrt boolean menuconfigs
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
	bool
	depends on BAZ [tristate]
if BAR
config FOO
	tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu
was used instead of an if block.

624fc7f52b V4L/DVB (5700): Saa7111: fix picture settings cache bug
If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.

The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.

When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers.  However, the
cached video_picture settings are not.

Resolve this by removing the useless and buggy second level of caching for
video_picture.  Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.

bbe2486fe3 V4L/DVB (5571): V4l1-compat: Make VIDIOCSPICT return errors in a useful way
Among other things, VIDIOCSPICT sets the pixel format.  Some drivers
don't support all formats, e.g. cx88 doesn't support the planar formats.
The compat code that translates VIDIOCSPICT into V4L2 ioctls doesn't pass
on any errors, so a userspace program doesn't know if it has selected an
unsupported pixel format.

VIDIOCSPICT sets both the memory capture and overlay formats, and it's
possible that one will be set while the other will fail, e.g. cx88
doesn't even support overlay.  Also, trying to set the overlay format
will fail for non-root users.

4f393828d1 V4L/DVB (5573): Pvrusb2: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.

After deletion, a sysfs node doesn't access anything outside sysfs 
proper, so there's no reason to hold onto the attribute owners.

Note that often the wrong modules were accounted for as owners leading 
to accessing removed modules. 

This patch kills now unnecessary attribute->owner.  

Note that with this change, userland holding a sysfs node does not 
prevent the backing module from being unloaded.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
