201f5c9caf V4L/DVB (5175): Pvrusb2: VIDIOC_DBG_[S|G]_REGISTER fixups
Support 64 bit register IDs internally.  Only allow root access to
this API (for both set and get).  Note that actual 64 bit access only
becomes possible once the definition for v4l2_register is updated, but
this change clears the way for it from the viewpoint of the pvrusb2
driver.

567d7115b9 V4L/DVB (5172): Pvrusb2: Control protocol cleanup
Several special-case FX2 commands were being issued through
pvr2_write_u16() and pvr2_write_8(), but there's really nothing
special case about them.  These date from a very early time in the
driver development.  This patch removes these functions and replaces
their use with calls to pvr2_send_request.

05ad390724 V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settings
The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly.  To work around
this, makefiles would define some new macro based on the setting of a
config variable.  e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary.  This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

b50e7fe993 V4L/DVB (5147): Make vivi driver to use vmalloced pointers
Before this patch, vivi were simulating a scatter gather DMA transfer.
While this is academic, showing how stuff really works on a real PCI 
device, this means a non-optimized code. 
There are only two memory models that vivi implements:
	1) kernel alloced memory. This is also used by read() method.
	   On this case, a vmalloc32 buffer is allocated at kernel;
	2) userspace allocated memory. This is used by most userspace apps.
	   video-buf will store this pointer.
	   a simple copy_to_user is enough to transfer data.
The third memory model scenario supported by video-buf is overlay mode. 
This model is not implemented on vivi and unlikely to be implemented on 
newer drivers, since now, most userspace apps do some post-processing 
(like de-interlacing).
After this patch, some cleanups may be done at video-buf.c to avoid 
allocating pages, when the driver doesn't need a PCI buffer. This is the 
case of vivi and usb drivers.

52ebc763d8 V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal only
The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such.  Officially export them.

VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER 
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h 
to videodev2.h.

Types used in struct v4l2_register are changed to the userspace 
exportable versions (u32 -> __u32, etc). 

Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move 
the check into the video_ioctl2() dispatcher so it doesn't need to be 
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is 
added to pvrusb2 (which doesn't use video_ioctl2).

Using it makes the driver simpler, and isolates API parsing.
This allows future reusage of driver controls using other ways, like sysfs

fd69496461 V4L/DVB (5095): Pvrusb2: Allow VIDIOC_S_FMT with -1 for resolution values
With the previous patch, mplayer started but was polling the video
device forever without any video actually coming out. Further analysis
showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!).
The code handling this only cares that both are lower than the minimum
range allowed so it ends up setting the size to 19x17 (!!) This pretty
much breaks the encoder here. Even if this breakage is yet another (TM)
result of my setup, setting the size to 19x17 by default would surprise
most users IMHO.
So, special case for -1 and interpret this to be a request for the
default size, please. Users can then set their favorite size both
through mplayer and through sysfs.
With this patch, mplayer finally works in pvr:// mode (not that we
really gain anything over operating it through sysfs with lirc,
sometime I might actually get off my lazy a** and contribute this
setup too)

VIDIOC_S_TUNER and also eliminates the now redundant code from the
audio chip handler.

horizontal blanking. VBI capturing can start and end on any line, 
including the picture area, and apps can capture different lines of each 
field and single fields.
For compatibility with existing applications, the open() function
resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP
call is necessary to actually enable cropping. 
Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image 
width will increase from 640 and 768 to 747 and 923 pixels respectively.
Like the VBI changes however, this should only affect applications which 
depend on former driver limitations, such as never getting more than 640 
pixels regardless of the requested width. 
Also, new freedoms require additional checks for conflicts and some 
applications may not expect an EBUSY error from the VIDIOC_QBUF and 
VIDIOCMCAPTURE ioctls. These errors should be rare though.
So far, the patch has been tested on a UP machine with a bt878 in PAL-
BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/
libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2

139eecf94c V4L/DVB (5053): Pvrusb2: Change default volume to something sane
The default volume of 65535 is too high.  Make is something smaller.
Note that this _only_ changes the default value.  Specifically, there
are no scaling or other more intrusive changes here.  I'm just sick of
constantly having to reduce the volume every time I plug in and test
the device!  (And unfortunately we can't do a better fix like scaling
the volume so that 65535 makes sense because doing so will screw up
any app - like MythTV - which expects the old scaling.)  Too bad V4L
controls don't have better defined ranges.

Trying to temporarily check that the stream is not claimed during open
of the radio device is at best a race condition.  What's to stop
another app from claiming the stream anyway the instant after the
check is done?  The implementation for this was dicey anyway.  So it's
removed.  The only "price" for this is that if /dev/radioX is opened
while streaming video, then the video stream is just going to switch
to radio mode anyway.  If a user does this, he gets what he expects...

ae2b9e25fd V4L/DVB (5039): Pvrusb2: Implement /dev/radioX
The "main" V4L2 interface patch. This is yet very incomplete, incorrect and
probably inappropriate for inclusion as-is, but at least with this I 'm able
to tune and play radio through a V4L2 program (pvr-radio.c, a "thumb" version
of ivtv-radio.c with just the essentials).

Therefore, it kinda gives an idea of what is needed to support this, hm,
interface (partly used also by e.g., kradio). Please point out any mistakes
on this code. I 'm sure I 'm messing up some struct initialization somewhere
but currently I 'm too lazy to actually think this through until I complete
the functionality (e.g., handle the VIDIOC_S_STD, ENUMINPUT, etc ioctls
appropriately).

99cfdf5cc6 V4L/DVB (5038): Pvrusb2: Implement stream claim checking function
Add (and expose) a new function, pvr2_channel_check_stream_no_lock(), in
pvrusb2-context.c. This is hopefully the last V4L2 interface related patch
to change anything outside pvrusb2-v4l2.c.

We need this to implement the open() for the radio device. The reason is
that within the *enter_context() section of open() we need to ensure nobody
is streaming and if we cannot, we should cleanup after ourselves and return
 -EBUSY. We cannot just use claim_stream() because:

   1) That would cause a deadlock trying to re-acquire the context lock
   2) We only need to ensure that nobody is streaming. We don't need to
      actually acquire the stream.

Again, this is a kinda ugly patch. Feel free to improve.

2fdf3d9c94 V4L/DVB (5037): Pvrusb2: Implement multiple minor device number handling
This is the first patch in preparation of the V4L2/IVTV radio interface.
It does away with the assumption of only one minor per device. It also
adds a file to show the radio minor as well. This can be useful for a
program like pvr-radio.c (when it grows up), since this way it can search
for the minor of the /dev/radioX device it opened and use the video minor
of the same driver instance to get to the actual stream.

The implementation looks kinda ugly. Feel free to improve (that is the
reason behind separate patches anyway).

6fcb5b3ef7 V4L/DVB (5036): Pvrusb2: Fix for min/max control value checking
In the previous patch we exploited the get_{min,max}_value facility to adjust
min/max allowable frequencies on the fly, depending on tuner mode.

Unfortunately, this facility was not used inside the *sym_to_val() function
that translates what we echo to sysfs, which means we got an -ERANGE despite
asking for a frequency between what we read to be min/max.
This patch corrects this small omission.

25d8527a44 V4L/DVB (5035): Pvrusb2: Enable radio mode round #2
This is the logic that:
  a) Ensures /sys/class/pvrusb2/sn-*/ctl_frequency/{max,min}_val are
     "automagically" reset to sane values on each mode change.

  b) Allows tuning to a radio frequency by something like:
     echo `perl -e "print int(94.9*16000 + 0.5)"` \
       > /sys/class/pvrusb2/sn-*/ctl_input/cur_val


The trick was to take advantage of the already existing .get_{min,max}_value
function pointers in pvr2_ctrl, to "dynamically override" the hardcoded values
for min/max frequency at runtime.

For a moment I thought to dispose of the hardcoded MIN/MAX_FREQ and use the
hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that
tuner-core.c kinda hardcodes these as well, so I decided to not bother.

275b2e283b V4L/DVB (5034): Pvrusb2: Enable radio mode round #1
This is the logic that supports switching modes via e.g.,
  echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val.

To do the mode switching we need to:
a) broadcast AUDC_SET_RADIO and
b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. 

The first is done by adding a new pvr2_i2c_op and having it trigger on 
input change, the second by adding this command in pvr2_encoder_start() 
and requesting an encoder restart on input change by setting 
stale_subsys_mask appropriately. 

The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly 
provided by Hans Verkuil on the pvrusb2 mailing list. The idea to 
implement mode switching this way (on input change) is due to Mike Isely.

Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, 
but I think this can be traced to a cornell student being the first to 
implement radio support in ivtv "as a different standard". I think the 
rest just evolved from there (it 's in the ivtv ML archives).

So these commands are removed. This also means that the V4L2_CID_MPEG_VIDEO_PULLDOWN
control in cx2341x.c and pvrusb2-hdw.c is removed.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

that the fixmap slot now points at a different physical page.

There was a still a pre-dvb-pll set_params function for the lgdt3302 in

dvb_pll_attach() for the cards that were using it (Dvico FusionHDTV 3
GOLD {Q,T}).  This way the set_params function from dvb-pll is used.
dvb_attach() is in turn used on dvb_pll_attach(), eliminating some static
dependencies on dvb-pll.  There are still a couple static dependencies on
dvb-pll remaining.

Fix long-standing issue which prevented use of 24xxx devices at any
horizontal resolution other an 720.  The problem is in the cx25840
module, if no attempt is made to initialize VBI there.  Such a thing
should not be needed, but the pvrusb2 driver is updated now to deal
with this.

76db93d03f V4L/DVB (4846): Create new lgh06xf atsc tuner module
This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners,
called lgh06xf.  The purpose of this change is to reduce some duplicated
code, and to allow the lgh06xf tuner code to take advantage of dvb_attach().
As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed,
since the lgh06xf module itself will use dvb-pll, while remaining optional
for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE

Unlike 29xxx devices, the 24xxx model series does not have a dedicated
I2C device for reception of IR codes.  Instead IR is handled directly
by the FX2 microcontroller and the results are communicated via
commands to the FX2.  Rather than implement a whole new IR reception
pathway for 24xxx devices, this changeset instead emulates the
presence of the 29xxx device's I2C based IR receiver by intercepting
commands to that chip and issuing appropriate FX2 commands to do the
needed action.  This has the result of allowing all the usual IR
frameworks (ir-kbd-i2c or lirc) to continue working unmodified for
24xxx devices.

6c5be74c86 V4L/DVB (4676): Dynamic cx88 mpeg port management for HVR1300 MPEG2/DVB-T support.
A series of patches to change the cx88 framework to allow the
PCI mpeg port to be shared dynamically between different
types of drivers or applications. This patch changes the cx88-dvb
and cx88-blackbird drivers to become 'sub drivers' of a higher
single cx88-mpeg driver.
The cx88-mpeg driver is a superset of the previous cx88-mpeg/blackbird
drivers and now owns the IRQ. cx88-dvb/blackbird now become mini drivers,
registering themselves with cx88-mpeg through a standard interface with
callbacks.
Sub drivers request access to hardware via the cx88-mpeg driver. In turn
the cx88-mpeg driver determines whether the hardware is busy and accepts
or refuses the request, grant access using callbacks into the sub drivers.
The net effect is that you are no longer able to tamper with the mpeg port
from multiple different applications at the same time, potentially breaking
a live mpeg2 hardware encoding or dvb stream.
The mechanism extends to enable multiple dvb frontends to be registered
and share the single resource.

0871a8849b V4L/DVB (4816): Change tuner type for Avermedia A16AR
This changes it from TDA8290 which is allegedly very unlikely to TD1316 which
is allegedly very likely. I didn't get it to work with either, but expected
that this got applied when Mauro sent it to me, so here it goes again; feel
free to drop it to the floor. :-)

450efcfd2e V4L/DVB (4814): Remote support for Avermedia 777
I didn't test it personally since I don't have this card, but A16AR uses the
same interface and that one certainly does work perfectly (see the next patch).
This patch was originally sent in
	http://marc.theaimsgroup.com/?l=linux-video&m=114743413825375&w=2
	https://www.redhat.com/mailman/private/video4linux-list/2006-May/msg00103.html
but never got applied. This version has some trivial modifications and drops
the weird gpio hack (it's not clear what practical purpose does it serve).

The call to v4l2_std_construct() in the VIDIOC_G_PARM handler treats
vfd->current_norm as if it were an index - but it's not.  The result is
an oops if the driver has no vidioc_g_parm() method defined.  Here's the
fix.
