[PATCH] Big zoran driver update 

This is a patch for the video4linux unified zoran driver that has been
in the kernel since 2.4.5 or so.

It fixes the compile issues in the current 2.6.0-test3 unified zoran
driver (current one doesn't compile at all), and also updates its
version to what we have in CVS.  This adds support for new cards (e.g.
LML33R10 from LinuxMediaLabs and DC30+ from Pinnacle), fixes bugs in
cards that were already supported and generally improves capture
reliability.  Changes per file (in detail) are given below. 

i2c-id.h:
  add some new IDs for new i2c drivers

pci_ids.h:
  add PCI IDs for each of the supported cards if it has any

saa7111.c, saa7110.c, adv7175.c, bt819.c, saa7185.c, bt856.c:
  update to whatever we've got in our CVS. For most, these are just
  "easiness" fixes that either add some better debug output, or that make
  maintainance for both 2.6.x and 2.4.x simpler for me. There's also some
  specific changes. E.g., in saa7110.c, we enable the VCR mode bits so we
  get a better image from VCR input. In all of them, we make debugging an
  insmod option rather than a compile-time option (this makes debugging
  for users a *lot* easier). Point is that I just want our latest CVS in
  here. Maintainance is going to be a personal horror-story if it's not.

vpx3220.c, saa7114.c, adv7170.c:
  new i2c ones (for respectively DC10/DC30, LML33R10 and again LML33R10)

zr36067.c:
  removed, the driver is now spread over multiple source files.

zoran*.[ch], zr36057.h
  spread-out source files. Also fixes lots of bugs, can't even start
  naming them all, you don't want that, neither do I. Just assume that it
  works better than it used to - it does.

  Nice things that aren't in the old driver: much more stable, supports
  DC30+, supports LML33R10, has proper locking/semaphores, supports
  multiple opens without races now, adapted to new i2c subsystem, v4l2
  support, Xv (hardware-scaled) overlay support, and a lot more.

  Oh, and this one actually compiles.

videocodec.[ch], zr360{16,50,60}.[ch]:
  new sublayer for the driver to unify how we handle the zr36060 chip
  (DC10(+)/LML33/LML33R10/Buz) and the zr36050/zr36016 (DC30(+)).

MAINTAINERS:
  add me as maintainer (I am).

Kconfig:
  add new cards, plus improve the descriptions.

Makefile:
  d'oh.

Zoran:
  documentation update.

Others:
  I don't think there are any.

Greg has gone over the i2c changes a long time ago, he agreed on all of
them. Gerd is supposed to take care of the v4l part, he has never
complained about any of them. Stability is good, we've fixed most issues
(there's still some out there, but nothing serious), lots better than in
the old driver. Also, the cards work much better than with the old
driver.

===========================
1.1 What the TV decoder can do an what not
The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
information is not enough. There are several formats of the TV standards.
And not every TV decoder is able to handle every format. Also the every
combination is supported by the driver. There are currently 11 different
tv broadcast formats all aver the world.
The CCIR defines parameters needed for broadcasting the signal.
The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
The CCIR says not much about about the colorsystem used !!!
And talking about a colorsystem says not to much about how it is broadcast.
The CCIR standards A,E,F are not used any more.
When you speak about NTSC, you usually mean the standard: CCIR - M using
the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
and a few others.
When you talk about PAL, you usually mean: CCIR - B/G using the PAL
colorsystem which is used in many Countries.
When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
which is used in France, and a few others.
There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
Ireland, Nigeria, South Africa.
The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
and is used in Argentinia, Uruguay, an a few others
We do not talk about how the audio is broadcast !
A rather good sites about the TV standards are:
http://www.sony.jp/ServiceArea/Voltage_map/
http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
and http://www.cabl.com/restaurant/channel.html
Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
be the same as NTSC 4.43.
NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
to split coma and luma instead of a Delay line.
But I did not defiantly find out what NTSC Comb is.
Philips saa7111 TV decoder
was introduced in 1997, is used in the BUZ and
can handle: PAL B/G/H/I, PAL N, PAL M, NTSC M, NTSC N, NTSC 4.43 and SECAM

===========================
1.2 What the TV encoder can do an what not
The TV encoder are doing the "same" as the decoder, but in the oder direction.
You feed them digital data and the generate a Composite or SVHS signal.
For information about the colorsystems and TV norm take a look in the
TV decoder section.

Compiling and Loading the Driver Information - video4linux:
================================
You should run a 2.2.x kernel in order to use this driver. The driver
was also tested with 2.4-test6 kernel, so hopefully it will work
with 2.4 kernels too.
I would recommend to use only official kernels from www.kernel.org and
its mirrors. Kernels supplied with some Linux distributions may be
patched in some way to meet specific needs of particular Linux
distributor and could be incompatible with this driver. As a driver
maintainer, I am not able to follow every unofficial kernel release,
and no unofficial kernels will be supported.
Besides the files in this directory, the driver needs the 'videodev'
and the 'i2c' module from the Linux kernel (i2c-old for 2.4 kernels).
In order to get these modules available, enable module support for
VIDEODEV and BTTV (which implies i2c) in your 2.2.x kernel
configuration. You will find these devices in the menu "Character
Devices" in your Kernel Configuration.
In newer kernels (2.4) instead of BTTV you should enable support for
Iomega Buz cards and for Zoran 36060/36067 chipset. This will include
i2c or i2c-old modules and Buz/LML33 driver. However, instead of
modules for Buz/LML33 driver from the kernel, use modules from _this_
driver.
To compile the driver, just type make.
Before you load the driver you must have a video device at major device
node 81. If you don't have it yet, do the following (as root!):
cd /dev
mknod video0 c 81 0
ln -s video0 video
If you have more than one card, add more nodes in /dev directory:
mknod video1 c 81 1
mknod video2 c 81 2
...
The driver should operate properly with several cards. It was tested
with one DC10plus and one LML33 cards installed together and the driver
correctly identifies both cards and works with both of them.
Currently the driver does not support LML33 and Buz cards installed
together in the same system. This will be fixed in future versions.
Edit the 'update' script if you want to give the driver special options
(see below for options descriptions) and then type (as root)
./update <card_list>
to insert all necessary modules into the kernel. <card_list> is a list of
cards installed in your system separated by white space. Supported cards
are dc10, dc10plus, lml33, and buz. For example, if you have both dc10plus
and lml33 cards, please type
./update dc10 lml33
If you want to make full use of the Video for Linux _uncompressed_
grabbing facilities, you must either
- obtain and install the "big_physarea patch" for your kernel and
set aside the necessary memory during boot time. There seem to be
several versions of this patch against various kernel versions
floating around in the net, you may obtain one e.g. from:
http://www.polyware.nl/~middelin/hob-v4l.html#bigphysarea
You also have to compile your driver AFTER installing that patch in
order to get it working
or
- start your kernel with the mem=xxx option, where xxx is your
real memory minus the memory needed for the buffers.
For doing this add an entry in lilo.conf (if you use lilo):
append "mem=xxxM"
or add a line in your linux.par file (if you use loadlin):
mem=xxxM
The second method is by far easier, however it is dangerous if more
than one driver at a time has the idea to use the memory leftover by
setting the mem=xxx parameter below the actual memory size.
Read also below how to use this memory!
If you use only MJPEG compressed capture provided by the driver, you
should not need large memory areas for DMA. In this case, you will be
able to capture and playback movies with lavtools, however you will
not be able to use capture features of XawTV and other similar
programs (you can still watch video on the screen).
Driver Options
==============
You are able to customize the behavior of the driver by giving
it some options at start time.
default_input, default_norm
---------------------------
As soon as the driver is loaded, the Buz samples video signals
from one of its input ports and displays it on its output.
The driver uses the Composite Input and the video norm PAL for this.
If you want to change this default behavior, set default_input=1
(for S-VHS input) or default_norm=1 for NTSC or default_norm=2
for SECAM (DC10/DC10plus only).
lock_norm
---------
This option was introduced to disable norm (TV standard) change by some
not well behaving programs. For example, if you have some application
which was written by somebody who lives in a country with PAL standard,
this program may not have NTSC option and may always try to set the
driver to PAL. In this case, you may load the driver with
default_norm=1 and lock_norm=1 and the card will be forced to work in
NTSC standard only.
Options:
lock_norm=0 default, TV standard change is enabled;
lock_norm=1 TV standard change is disabled but the driver
will not notify the application about any error;
lock_norm=2 TV standard change is disabled and the driver
will notify the program that TV standards other
than set by default_norm=X option are not
supported.
pass_through
------------
When the driver is not in use (device is not opened by any program) and
pass_through=0 (default) the driver will set the TV encoder to produce
color bar signal at the output. If the driver was loaded with
pass_through=1, the color bar will be disabled and input signal will be
sent to the output even if the driver not in use. If you have LML33 card
and wish the color bar signal at the output, you will also need to set
lml33dpath=1 (please, see next section).
lml33dpath
----------
LML33 card normally (lml33dpath=0) connects its output to the input
using analog switch. Additionally, it also allows real-time monitoring
of digitized video using TV monitor connected to the output. This
"digital path" option can be enabled setting lml33dpath=1. In this
mode, the input is connected only to the TV decoder, digital video data
is sent via internal video bus to the TV encoder and resulting analog
signal is sent to the output. This mode could be very useful for testing and
picture adjustment while watching video at the TV monitor connected to
the output. However, because of lack of 75 ohm terminating resistors at
TV decoder input, the signal will suffer serious distortions.
# These distortions could be eliminated by soldering two 75 ohm resistors
# in LML33 card: in parallel to capacitors C73 and C82 (see schematics of
# H33 board available at www.linuxmedialabs.com and www.zoran.com). Be
# aware, however, that doing so will void card warranty and the card,
# after this change, must always be used with loading option lml33dpath=1.
#
# WARNING: I DID NOT TRY THIS CARD CHANGE YET, THIS IS JUST AN ASSUMPTION
# AND I WILL NOT BE RESPONSIBLE FOR ANY DAMAGE ASSOCIATED WITH THIS
# CHANGE. IF YOU WISH TO TRY IT, DO IT AT YOUR OWN RISK.
Please, note that DC10/DC10plus cards always use "digital path" for
signal monitoring. Its input and output are both properly terminated
and the digitized signal quality does not depend on the connection of
the output load.
v4l_nbufs, v4l_bufsize
----------------------
In order to make to make full use of the Video for Linux uncompressed
picture grabbing facilities of the driver (which are needed by many
Video for Linux applications), the driver needs a set of physically
contiguous buffers for grabbing. These parameters determine how many
buffers of which size the driver will allocate at open (the open will
fail if it is unable to do so!).
These values do not affect the MJPEG grabbing facilities of the driver,
they are needed for uncompressed image grabbing only!!!
v4l_nbufs is the number of buffers to allocate, a value of 2 (the default)
should be sufficient in almost all cases. Only special applications
(streaming captures) will need more buffers and then mostly the
MJPEG capturing features of the Buz will be more appropriate.
So leave this parameter at it's default unless you know what you do.
The things for v4l_bufsize are more complicated: v4l_bufsize is set by
default to 128 [KB] which is the maximum amount of physically
contiguous memory Linux is able to allocate without kernel changes.
This is sufficient for grabbing 24 bit color images up to sizes of
approx. 240x180 pixels (240*180*3 = 129600, 128 KB = 131072).
In order to be able to capture bigger images you have either to
- obtain and install the "big_physarea patch" and set aside
the necessary memory during boot time or
- start your kernel with the mem=xxx option, where xxx is your
real memory minus the memory needed for the buffers.
In that case, useful settings for v4l_bufsize are
- 1296 [Kb] for grabbing 24 bit images of max size 768*576
- 1728 [Kb] for 32bit images of same size (4*768*576 = 1728 Kb!)
You may reduce these numbers accordingly if you know you are only
grabbing 720 pixels wide images or NTSC images (max height 480).
In some cases it may happen that Linux isn't even able to obtain
the default 128 KB buffers. If you don't need uncompressed image
grabbing at all, set v4l_bufsize to an arbitrary small value (e.g. 4)
in order to be able to open the video device.
triton, natoma
--------------
The driver tries to detect if you have a triton or natoma chipset
in order to take special measures for these chipsets.
If this detection fails but you are sure you have such a chipset,
set the corresponding variable to 1.
This is a very special option and may go away in the future.
Tested applications
===================
XawTV to watch video on your computer monitor.
kwintv the same (you might need to use option lock_norm=1).
lavtools To record and playback AVI or Quicktime files. Note: you
will need patched version, lavtools-1.2p2 to support new
features of this driver. Please visit driver homepage for
more info.
Broadcast2000 reportedly (I didn't try that) can accept movies recorded
by lavrec in Quicktime format for editing and then edited
movie can be played back by lavplay program.
MainActor 3.5x also can accept movies recorded by lavrec for editing.
The driver can to be used by two programs at the same time
(please, see warning note below regarding this feature). Using XawTV
you can watch what you are recording or playing back with lavtools.
I've tested the following sequence and it worked for me:
* start xawtv and switch inputs, TV standards, and adjust video
(contrast, saturation, etc.). You may also run your favorite
audio mixer application to adjust audio inputs.
* run lavrec with options:
-i<set your input and norm here> (to choose proper input
and TV standard)
-l -1 (to use audio mixer settings)
Other lavrec option can be added at your choice.
* watch the movie in xawtv window while recording it as AVI or
Quicktime file.
* when recording is finished, run lavplay or xlav and watch your
clip in xawtv window.
* Note: you should not quit xawtv during recording or playing back.
If you quit xawtv during recording or playback, another lavtools
program will stop and may even crash.
I'm not sure that the same will work for you. You can try but,
please, be careful.
WARNING! This is an experimental feature and I'm not sure if it will be
supported in the future. The original driver was not designed to be
used like this and it has no protection against any interference
between two running programs. THEREFORE, IT IS POTENTIALLY DANGEROUS
AND SINCE THE DRIVER OPERATES IN KERNEL SPACE, USING THIS FEATURE MAY
CRASH YOUR ENTIRE SYSTEM.
Programming interface
=====================
This driver should be fully compliant to Video for Linux, so all
tools working with Video for Linux should work with (hopefully)
no problems.
A description of the Video for Linux programming interface can be found at:
http://roadrunner.swansea.linux.org.uk/v4lapi.shtml http://roadrunner.swansea.linux.org.uk/v4lapi.shtml
/usr/src/linux/Documentation/video4linux/API.html
/usr/include/linux/videodev.h
Besides the Video for Linux interface, the driver has a "proprietary" Information - video4linux/mjpeg extensions:
interface for accessing the Buz's MJPEG capture and playback facilities. ./zoran.h
(also see below)
For a full description of all members and ioctls see "zoran.h" (used to Information - video4linux2:

attach that file with kernel messages as plain text (please, don't
attach it using base64, uuencode, or any other encoding). Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
actually use that number or not, but that's not too important right now.
If you have a Buz card, please, also mail the same message to
Wolfgang Scherr <scherr@net4you.net> 704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
output becomes 512 bits per block. Actually 510, but 512 is simpler to use
for calculations.
Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
here, so we don't need to do any fancy corrections for bits-per-pixel or such
things. 101376 bytes per field.
d1 video contains two fields per frame. Those sum up to 202752 bytes per
frame, and one of those frames goes into each buffer.
But wait a second! -b128 gives 128kB buffers! It's not possible to cram
202752 bytes of JPEG data into 128kB!
This is what the driver notice and automatically compensate for in your
examples. Let's do some math using this information:
128kB is 131072 bytes. In this buffer, we want to store two fields, which
leaves 65536 bytes for each field. Using 3168 blocks per field, we get
20.68686868... available bytes per block; 165 bits. We can't allow the
request for 256 bits per block when there's only 165 bits available! The -q50
option is silently overridden, and the -b128 option takes precedence, leaving
us with the equivalence of -q32.
This gives us a data rate of 165 bits per block, which, times 3168, sums up
to 65340 bytes per field, out of the allowed 65536. The current driver has
another level of rate limiting; it won't accept -q values that fill more than
6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
a safe bet. Personally, I think I would have lowered requested-bits-per-block
by one, or something like that.) We can't use 165 bits per block, but have to
lower it again, to 6/8 of the available buffer space: We end up with 124 bits
per block, the equivalence of -q24. With 128kB buffers, you can't use greater
than -q24 at -d1. (And PAL, and 704 pixels width...)
The third example is limited to -q24 through the same process. The second
example, using very similar calculations, is limited to -q48. The only
example that actually grab at the specified -q value is the last one, which
is clearly visible, looking at the file size.
--
Conclusion: the quality of the resulting movie depends on buffer size, quality,
whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
module to do 1:4 instead of 1:2 compression, etc.
If you experience timeouts, lowering the quality/buffersize or using
'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
proven by the Buz.
===========================
7. It hangs/crashes/fails/whatevers! Help!
Make sure that the card has its own interrupts (see /proc/interrupts), check
the output of dmesg at high verbosity (load zoran.o/zr36067.o with debug=2,
load all other modules with debug=1). Check that your mainboard is favorable
(see question 2) and if not, test the card in another computer. Also see the
notes given in question 3 and try lowering quality/buffersize/capturesize
if recording fails after a period of time.
If all this doesn't help, give a clear description of the problem including
detailed hardware information (memory+brand, mainboard+chipset+brand, which
MJPEG card, processor, other PCI cards that might be of interest), give the
system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
the kernel version, driver version, glibc version, gcc version and any other
information that might possibly be of interest. Also provide the dmesg output
at high verbosity. See 'Contacting' on how to contact the developers.

/* =================== */
/* general description */
/* =================== */
/* Should ease the (re-)usage of drivers supporting cards with (different)
video codecs. The codecs register to this module their functionality,
and the processors (masters) can attach to them if they fit.
The codecs are typically have a "strong" binding to their master - so I
don't think it makes sense to have a full blown interfacing as with e.g.
i2c. If you have an other opinion, let's discuss & implement it :-)))
Usage:
The slave has just to setup the videocodec structure and use two functions:
videocodec_register(codecdata);
videocodec_unregister(codecdata);
The best is just calling them at module (de-)initialisation.
The master sets up the structure videocodec_master and calls:
codecdata=videocodec_attach(master_codecdata);
videocodec_detach(codecdata);
The slave is called during attach/detach via functions setup previously
during register. At that time, the master_data pointer is set up
and the slave can access any io registers of the master device (in the case
the slave is bound to it). Otherwise it doesn't need this functions and
therfor they may not be initialized.
The other fuctions are just for convenience, as they are for shure used by
most/all of the codecs. The last ones may be ommited, too.
See the structure declaration below for more information and which data has
to be set up for the master and the slave.
----------------------------------------------------------------------------
The master should have "knowledge" of the slave and vice versa. So the data
structures sent to/from slave via set_data/get_data set_image/get_image are
device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)
----------------------------------------------------------------------------
*/
/* ========================================== */
/* description of the videocodec_io structure */
/* ========================================== */
/*
==== master setup ====
name -> name of the device structure for reference and debugging
master_data -> data ref. for the master (e.g. the zr36055,57,67)
readreg -> ref. to read-fn from register (setup by master, used by slave)
writereg -> ref. to write-fn to register (setup by master, used by slave)
this two functions do the lowlevel I/O job
==== slave functionality setup ====
slave_data -> data ref. for the slave (e.g. the zr36050,60)
check -> fn-ref. checks availability of an device, returns -EIO on failure or
the type on success
this makes espcecially sense if a driver module supports more than
one codec which may be quite similar to access, nevertheless it
is good for a first functionality check
-- main functions you always need for compression/decompression --
set_mode -> this fn-ref. resets the entire codec, and sets up the mode
with the last defined norm/size (or device default if not
available) - it returns 0 if the mode is possible
set_size -> this fn-ref. sets the norm and image size for
compression/decompression (returns 0 on success)
the norm param is defined in videodev.h (VIDEO_MODE_*)
additional setup may be available, too - but the codec should work with
some default values even without this
set_data -> sets device-specific data (tables, quality etc.)
get_data -> query device-specific data (tables, quality etc.)
if the device delivers interrupts, they may be setup/handled here
setup_interrupt -> codec irq setup (not needed for 36050/60)
handle_interrupt -> codec irq handling (not needed for 36050/60)
if the device delivers pictures, they may be handled here
put_image -> puts image data to the codec (not needed for 36050/60)
get_image -> gets image data from the codec (not needed for 36050/60)
the calls include frame numbers and flags (even/odd/...)
if needed and a flag which allows blocking until its ready

/* user interface */
/* ============== */
/*
Currently there is only a information display planned, as the layer
is not visible for the user space at all.
Information is available via procfs. The current entry is "/proc/videocodecs"
but it makes sense to "hide" it in the /proc/video tree of v4l(2) --TODO--.
A example for such an output is:
<S>lave or attached <M>aster name type flags magic (connected as)
S zr36050 0002 0000d001 00000000 (TEMPLATE)
M zr36055[0] 0001 0000c001 00000000 (zr36050[0])
