Implemented here is a new per-instance module option (ir_mode) which is

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.

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:

Biggest flaw of the I2C protocol: the R/W bit is the LSB instead of the

follows them, or if they are 8-bit and the R/W bit is OR-ed into the

One bit wide bitfields need to declared unsigned to have the range 0 to
1, or they have the range -1 to 0.
A few techniques to reduce the driver's size by about 1700 bytes on ia32,
probably more on x86-64.
Put the biggest fields first, less padding is necessary that way.
Put fields with a limited range into a smaller type. For example
VideoChannels will fit in 3 bits, and TunerType can use 8 bits.
Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but
they can't just go into an 8-bit field with no changes, since -1 was used
as a flag to indicate a value was not present. So what we do is create a
one-bit flag for each one to indicate if a value is or is not present.
This only takes 9 bits and has the added advantage that when the register
isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the
structure definition since the default value for the flag will be zero.

There were many places in the driver which had long sequences of constant
register initializations. These were done with one function call per
register. The register address and value were immediate values in the
function calls.
This is very inefficient, as each register and value take twice the space
when they are code, as each includes a push instruction to put it on
the stack. There there is the overhead, both size and time, for a
function call for each register. It's also quite a few lines of C code
to do this.
The patch creates a function that writes multiple registers from a list,
and a macro that makes it easy to construct a such a list as a const
static local to send to the function.
This gets rid of quite a bit of C code, and shrinks the driver by around
8k, while at the same time being more efficient.

I have a Cisco VT Camera, and it was just collecting dust. I decided to
try connecting it to my Linux box at home.
Just a disgression about the product. The Cisco VT Camera is a webcam
Cisco sold to work with their IP phone hardware and software. It's mostly
useless on Windows, as it interfaces only to Cisco software. You can find
some for cheap on eBay...
Physically, it's just a Logitech Pro 4000. The only difference with the
Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe
Cisco is now selling the Cisco VT Camera II, which look to be something
else...
So, assuming that it was a Pro 4000 inside, I created the little patch
attached.
I'm new to webcam under Linux, but I managed to get an image from it using
xawtv, and the image looked all right, so I consider that a success. The
imaged seemed a bit small and I could not get the microphone driver loaded,
but I assume it's my lack of experience. Note that I did not try any other
type_id, but this one works great.

Once the devices have been registered anyone can start changing the inputs or
TV standard before they have been initialized by the driver. This leads to
cases were the input is changed in an udev rule, but after that rule is
triggered the tail-end of the ivtv driver initialization can override
that by selecting the tuner input.
The correct sequence is to first setup the input, initial frequency and TV
standard before finally registering the video devices. This prevents any
udev rules from being triggered prematurely.

The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

The out of tree v4l-dvb build system didn't always override the kernel's

this, makefiles would define some new macro based on the setting of a

CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this

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

After this patch, some cleanups may be done at video-buf.c to avoid

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).

video_ioctl2 handler provides V4L2 API parsing.
Using it makes the driver simpler, and isolates API parsing.
This allows future reusage of driver controls using other ways, like sysfs

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)

Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting
applications to capture or overlay a subsection of the picture or to
extend the capture window beyond active video, into the VBI area and the
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

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

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

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.

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).

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 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.

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).
