I have a GeoVision GV-800(S) card, it has 4 CONEXANT BT878A chips.
It has 16 video inputs and 4 audio inputs, and it is almost identical
to the GV-800, as seen on http://bttv-gallery.de .
The only difference appears to be the analog mux, it has a CD22M3494
in place of the MT8816AP. The card has a blue PCB, as seen in this
picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg .
This card wasn't originally supported, and it was detected as
UNKNOWN/GENERIC. The video inputs weren't working, so I tried
"forcing" a few cards like the GeoVision GV-600, but there was still
no video. So I made a patch to support this card, based on the Kodicom
4400r.
The GV-800(S) is identified as follows:

As you can see, the GV-800(S) card is almost identical to the GV-800
on bttv-gallery, so this patch might also work for that card. If not,
only a few changes should be required on the gv800s_write() function.
After this patch, the video inputs work correctly on linux 2.6.24 and
2.6.27 using the software 'motion'. The input order may seem a little
odd, but it's the order the original software/driver uses, and I decided
to keep that order to get the most out of the card.
I tried to get the audio working with the snd-bt87x module, but I only
get noise from every audio input, even after selecting a different mux
with alsamixer. Also, after trying to play sound from those sources, I
randomly get a RISC error about an invalid RISC opcode, and then that
output stops working. I also can't change the sampling rate when
recording. Any pointers to adding audio support are welcome.

Some code was calling v4l2_video_std_construct() when all it cared about
was the frame period. So make a function that just returns that and have
v4l2_video_std_construct() use it.
At this point there are no users of v4l2_video_std_construct() left outside
of v4l2-ioctl, so it could be un-exported and made static.
Change v4l2_video_std_construct() so that it doesn't zero out the struct
v4l2_standard passed in. It's already been zeroed out in the common ioctl
code.

If an ioctl is read-only then the driver fills in all the fields. Lots of
times drivers only care about some fields so it's best if video_ioctl2
takes care of zeroing out the entire structure before handing it to the
driver. This saves code in each driver to do it and driver authors often
forget.
The existing memset code in some of the read-only ioctl handlers
can be deleted.

There are many RW ioctls() in v4l2 where userspace only supplies one or two
of the first fields in the structure passed to the ioctl. The driver then
fills in the rest of the fields.
Instead of copying the entire structure from userspace to the kernel we
only need to copy those fields that userspace is actually supposed to
supply.
What's more, the fields that are meant to be only be output from the driver
can be zeroed out in the videodev code, in case the driver doesn't fill
them all in. Many of the ioctl handlers in v4l2_ioctl do this already, but
my patch does this at one common point and so all the memsets for each
ioctl can be deleted.
For VIDIOC_G_SLICED_VBI_CAP, which has one input field ('type') and other
output-only fields, the input field is near the end of the structure
instead of at the beginning. So there is still a memset in it's ioctl
handler to zero out the beginning of the struct.
There were a couple mistakes with the existing code:
For VIDIOC_G_AUDIO the index field was preserved, but G_AUDIO is a read
only ioctl so nothing is copied from userspace to preserve.
For VIDIOC_G_FREQUENCY the tuner field was not preserved like it should
have been. This would be a problem if there was any hardware with more
than one tuner/modulator.
For VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS, none of the
fields were preserved even though each ioctl has several field that are
supposed to be inputs to the driver! Obviously these ioctls don't get
used much. The index field is needed if the driver has multiple
discrete sizes/rates and other fields can be used too, e.g. if the size
depends on pixel format or frame rate depends on image size for
example.

For VIDIOC_QUERYBUF only the first two fields, size and type, are used as
input. The rest can be filled in by the driver as output. Most drivers do
not actually use all the field and unused ones should be zeroed out. Some
drivers have code to do this and some drivers should but don't. So put
some zero out code in v4l2_ioctl so that all drivers using that system get
it.
The drivers that have zeroing code get that code removed.
Some drivers checked that the type field was valid, but v4l2_ioctl already
does this so those checks can be removed as well.

Note, the cx18 integrated A/V digitizer will now make a host match at address 1,

At least 3 Vimicro cameras (0x332d, 0x3410 and 0x3420) fail to return correct
bandwidth information. The first model rounds the value provided by the host
to the nearest supported packet size, while the other two always request the
maximum bandwidth.
Introduce a device quirk to override the value returned by the device with an
estimated bandwidth computed by the driver from the frame size and frame rate,
and enable it for all Vimicro cameras.

The bttv driver had static array of structures for up to 16 possible bttv
devices, even though few users have more than one or two. The structures
were quite large and this resulted in a huge BSS segment.
Change the driver to allocate the bttv device data dynamically, which
changes "struct bttv bttvs[BTTV_MAX]" to "struct bttv *bttvs[BTTV_MAX]".
It would be nice to get ride of "bttvs" entirely but there are some
complications with gpio access from the audio & mpeg drivers.
To help bttvs removal along anyway, I changed the open() methods use the
video device's drvdata to get the driver data instead of looking it up in
the bttvs array. This is also more efficient. Some WARN_ON()s are added
in cases the device node exists by the bttv device doesn't, which I don't
think should be possible.
The gpio access functions need to check if bttvs[card] is NULL now. Though
calling them on a non-existent card in the first place is wrong, but hard
to solve given the fundamental problems in how the gpio access code works.
This patch reduces the bss size by 66560 bytes on ia32. Overall change is a
reduction of 66398 bytes, as the WARN_ON()s add some 198 bytes.

Over half of the card database was used to store muxsel data. 64 bytes
were used to store one 32 bit word for each of up to 16 inputs.
The Bt8x8 only has two bits to control its mux, so muxsel data for 16
inputs will fit into a single 32 bit word. There were a couple cards that
had special muxsel data that didn't fit in two bits, but I cleaned them up
in earlier patches.
Unfortunately, C doesn't allow us to have an array of bit fields. This
makes initializing the structure more of a pain. But with some cpp magic,
we can do it by changing:
.muxsel = { 2, 3, 0, 1 },
.muxsel = { 2, 2, 2, 2, 3, 3, 3, 3, 1, 1 },
Into:
.muxsel = MUXSEL(2, 3, 0, 1),
.muxsel = MUXSEL(2, 2, 2, 2, 3, 3, 3, 3, 1, 1),
That's not so bad. MUXSEL is a fancy macro that packs the arguments (of
which there can be one to sixteen!) into a single word two bits at a time.
It's a compile time constant (a variadic function wouldn't be) so we can
use it to initialize the structure. It's important the the arguments to
the macro only be plain decimal integers. Stuff like "0x01", "(2)", or
"MUX3" won't work properly.
I also created an accessor function, bttv_muxsel(btv, input), that gets the
mux bits for the selected input. It makes it cleaner to change the way the
muxsel data is stored.
This patch doesn't change the code size and decreases the datasegment by
9440 bytes.

This card apparently uses an external mux and the Bt878's mux should always
be set to MUX2. The values for the external mux control bits were stored
in the muxsel field. This meant that when changing inputs the driver would
switch the Bt878's mux to whatever value the external mux was supposed to
be set to, then eagle_muxsel() would switch it back to MUX2 and program the
external mux. This creates an unnecessary switch of the Bt878's mux.
So change muxsel to be 2 for each input. The external mux bits are just
"input&3" so they don't really need to be stored anywhere. This also
eliminates the last non-standard use of the muxsel data.

Old versions of the bttv driver would use the high nibble of an input's
muxsel value to program the GPIO lines enabled via gpiomask2. Apparently
this was supposed to be for switching external audio muxes. Anyway, the
code that did this was removed sometime in the pre-git 2.6 series.
The RemoteVision MX board used this feature to control an external video
mux and I guess no one noticed when they removed the code.
Move the extra gpio mux data out of the high nibble of muxsel and to
rv605_muxsel(), then have that function set the gpio lines with it.
From looking at the CD22M3494E datasheet, it seems like the mdelay(1) is a
much longer delay than necessary. It looks like only around 20 ns is
necessary.

The card data for BTTV_BOARD_IVC120 set muxsel to a bunch of bogus values
(1 to 16), which the common mux code would use to set the Bt878's mux to
some random value. Then the custom code in ivc120_muxsel() would change
the Bt878's mux to the right value (always MUX0).
Better to just make the muxsel data correct (all zeros, easy!) and get the
mux right to begin with. Then the extra Bt878 mux setting code in
ivc120_muxsel() can be eliminated (the rest of the code for the IVC-120G's
external mux is still there of course).
This will help me clean up muxsel for some other changes. It should also
get rid of an unnecessary mux switch when changing from certain inputs to
certain other inputs on the IVC-120G.

The code was using a muxsel value of -1U to indicate a digital input. A
couple places in were checking of muxsel < 0 to detect this, which doesn't
work of course because muxsel is unsigned and can't be negative.
Only a couple cards had digital inputs and it was always the last one, so
for the card database create a one bit field that indicates the last input
is digital. On init, this is used to set a new field in the bttv struct to
the digital input's number or UNSET for none. This makes it easier to
check if the current input is digital.

The bttv card database is quite large and the data structure used to store
it wasn't very efficient. Most of the field are only used at card
initialization time so it doesn't matter if they aren't efficient to
access.
Overall the changes reduce code size by 60 bytes in ia32. The data size is
decreased by 5024 byes. It is probably even more for 64-bit kernels.
Move the fields in the struct around to be sorted from largest to smallest.
This saves on padding space used for alignment.
Get rid of the unused digital_mode field. Leave the setting as a comment
in the few cards entries that set it, in case someone ever writes the code.
Get rid of the unused audio_inputs field. Leave the values in the card
entries in case someone ever writes code that might use it.
Get ride of the unused radio_addr field. No card entries even set it to
anything interesting so it's not left as comments. All the code that used
it was removed in commit v2.6.14-3466-g291d1d7 from Nov 8th 2005.
Reduce video_inputs to u8 as no card has more than 255 inputs (the most is

Change tuner_addr to u8. I2C addresses are only seven bits and 255 means
ADDR_UNSET, so everything fits.
Make has_radio a one bit flag.
Make the pll setting a two bit field.

the value for no s-video input from UNSET (which is -1U and out of range of
four bits) to NO_SVHS (which is now 15).

The bttv card database structure had a "tuner" field that was the input
number of the tuner input or UNSET for no tuner. However, the only values
it could ever be are 0 and UNSET. Having a tuner on an input other than 0
didn't work and was never used.
There is also a "tuner_type" field that can be set to TUNER_ABSENT to
indicate no tuner, which makes "tuner = UNSET" redundant. In many cases,
tuner_type was set to UNSET when there was no tuner, which isn't quite
correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet
known.
So, I changed cards where "tuner == UNSET" to always have tuner_type of
TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it.
I have the card setup code set the card's tuner_type (not the card type's
tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the
setup code. Various places that check if the card has a tuner will now
look for this instead of checking the card type's "tuner" field.
Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C
client call instead of after issuing it.
Overall, on ia32 this decreases compiled code size by about 24 bytes and
reduces the data size by 640 bytes.

The code to set the norm for the TDA9880 analog demod was comparing
btv->norm, an index into the bttv driver's norm array, to V4L2_STD_NTSC,
which is a bit flag that's part of the V4L2 API. This doesn't work of
course and results in the PAL path always being taken.
What's more, it modified the bttv_tvcards[] entries for cards using the
TDA9880. This is wrong because changing the norm on one card will also
affect other cards of the same type. Writing to bttv_tvcards is also bad
because it should be read-only or even devinitdata.
Changing the norm would also cause the audio to become unmuted.

(which where the gpios are set) to avoid needed to modify bttv_tvcards.
