V4L/DVB (4887): Remove the broken VIDEO_ZR36120 driver
The VIDEO_ZR36120 driver has: - already been marked as BROKEN in 2.6.0 three years ago and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases.

Driver for Trust Computer Products Framegrabber, version 0.6.1
|
||||
------ --- ----- -------- -------- ------------ ------- - - -
|
||||

- ZORAN ------------------------------------------------------
|
||||
Author: Pauline Middelink <middelin@polyware.nl>
|
||||
Date: 18 September 1999
|
||||
Version: 0.6.1
|
||||
|
||||
- Description ------------------------------------------------
|
||||
|
||||
Video4Linux compatible driver for an unknown brand framegrabber
|
||||
(Sold in the Netherlands by TRUST Computer Products) and various
|
||||
other zoran zr36120 based framegrabbers.
|
||||
|
||||
The card contains a ZR36120 Multimedia PCI Interface and a Philips
|
||||
SAA7110 Onechip Frontend videodecoder. There is also an DSP of
|
||||
which I have forgotten the number, since i will never get that thing
|
||||
to work without specs from the vendor itself.
|
||||
|
||||
The SAA711x are capable of processing 6 different video inputs,
|
||||
CVBS1..6 and Y1+C1, Y2+C2, Y3+C3. All in 50/60Hz, NTSC, PAL or
|
||||
SECAM and delivering a YUV datastream. On my card the input
|
||||
'CVBS-0' corresponds to channel CVBS2 and 'S-Video' to Y2+C2.
|
||||
|
||||
I have some reports of other cards working with the mentioned
|
||||
chip sets. For a list of other working cards please have a look
|
||||
at the cards named in the tvcards struct in the beginning of
|
||||
zr36120.c
|
||||
|
||||
After some testing, I discovered that the carddesigner messed up
|
||||
on the I2C interface. The Zoran chip includes 2 lines SDA and SCL
|
||||
which (s)he connected reversely. So we have to clock on the SDA
|
||||
and r/w data on the SCL pin. Life is fun... Each cardtype now has
|
||||
a bit which signifies if you have a card with the same deficiency.
|
||||
|
||||
Oh, for the completeness of this story I must mention that my
|
||||
card delivers the VSYNC pulse of the SAA chip to GIRQ1, not
|
||||
GIRQ0 as some other cards have. This is also incorporated in
|
||||
the driver be clearing/setting the 'useirq1' bit in the tvcard
|
||||
description.
|
||||
|
||||
Another problems of continuous capturing data with a Zoran chip
|
||||
is something nasty inside the chip. It effectively halves the
|
||||
fps we ought to get... Here is the scenario: capturing frames
|
||||
to memory is done in the so-called snapshot mode. In this mode
|
||||
the Zoran stops after capturing a frame worth of data and wait
|
||||
till the application set GRAB bit to indicate readiness for the
|
||||
next frame. After detecting a set bit, the chip neatly waits
|
||||
till the start of a frame, captures it and it goes back to off.
|
||||
Smart ppl will notice the problem here. Its the waiting on the
|
||||
_next_ frame each time we set the GRAB bit... Oh well, 12,5 fps
|
||||
is still plenty fast for me.
|
||||
-- update 28/7/1999 --
|
||||
Don't believe a word I just said... Proof is the output
|
||||
of `streamer -t 300 -r 25 -f avi15 -o /dev/null`

syncer: done
|
||||
writer: done
|
||||
(note the /dev/null is prudent here, my system is not able to
|
||||
grab /and/ write 25 fps to a file... gifts welcome :) )
|
||||
The technical reasoning follows: The zoran completed the last
|
||||
frame, the VSYNC goes low, and GRAB is cleared. The interrupt
|
||||
routine starts to work since its VSYNC driven, and again
|
||||
activates the GRAB bit. A few ms later the VSYNC (re-)rises and
|
||||
the zoran starts to work on a new and freshly broadcasted frame....
|
||||
|
||||
For pointers I used the specs of both chips. Below are the URLs:
|
||||
http://www.zoran.com/ftp/download/devices/pci/ZR36120/36120data.pdf
|
||||
http://www-us.semiconductor.philips.com/acrobat/datasheets/SAA_7110_A_1.pdf
|
||||
Some alternatives for the Philips SAA 7110 datasheet are:
|
||||
http://www.datasheetcatalog.com/datasheets_pdf/S/A/A/7/SAA7110.shtml
|
||||
http://www.datasheetarchive.com/search.php?search=SAA7110&sType=part
|
||||
|
||||
The documentation has very little on absolute numbers or timings
|
||||
needed for the various modes/resolutions, but there are other
|
||||
programs you can borrow those from.
|
||||
|
||||
------ Install --------------------------------------------
|
||||
Read the file called TODO. Note its long list of limitations.
|
||||
|
||||
Build a kernel with VIDEO4LINUX enabled. Activate the
|
||||
BT848 driver; we need this because we have need for the
|
||||
other modules (i2c and videodev) it enables.
|
||||
|
||||
To install this software, extract it into a suitable directory.
|
||||
Examine the makefile and change anything you don't like. Type "make".
|
||||
|
||||
After making the modules check if you have the much needed
|
||||
/dev/video devices. If not, execute the following 4 lines:
|
||||
mknod /dev/video c 81 0
|
||||
mknod /dev/video1 c 81 1
|
||||
mknod /dev/video2 c 81 2
|
||||
mknod /dev/video3 c 81 3
|
||||
mknod /dev/video4 c 81 4
|
||||
|
||||
After making/checking the devices do:
|
||||
modprobe i2c
|
||||
modprobe videodev
|
||||
modprobe saa7110 (optional)
|
||||
modprobe saa7111 (optional)
|
||||
modprobe tuner (optional)
|
||||
insmod zoran cardtype=<n>
|
||||
|
||||
<n> is the cardtype of the card you have. The cardnumber can
|
||||
be found in the source of zr36120. Look for tvcards. If your
|
||||
card is not there, please try if any other card gives some
|
||||
response, and mail me if you got a working tvcard addition.
|
||||
|
||||
PS. <TVCard editors behold!)
|
||||
Don't forget to set video_input to the number of inputs
|
||||
you defined in the video_mux part of the tvcard definition.
|
||||
It's a common error to add a channel but not incrementing
|
||||
video_input and getting angry with me/v4l/linux/linus :(
|
||||
|
||||
You are now ready to test the framegrabber with your favorite
|
||||
video4linux compatible tool
|
||||
|
||||
------ Application ----------------------------------------
|
||||
|
||||
This device works with all Video4Linux compatible applications,
|
||||
given the limitations in the TODO file.
|
||||
|
||||
------ API ------------------------------------------------
|
||||
|
||||
This uses the V4L interface as of kernel release 2.1.116, and in
|
||||
fact has not been tested on any lower version. There are a couple
|
||||
of minor differences due to the fact that the amount of data returned
|
||||
with each frame varies, and no doubt there are discrepancies due to my
|
||||
misunderstanding of the API. I intend to convert this driver to the
|
||||
new V4L2 API when it has stabilized more.
|
||||
|
||||
------ Current state --------------------------------------
|
||||
|
||||
The driver is capable of overlaying a video image in screen, and
|
||||
even capable of grabbing frames. It uses the BIGPHYSAREA patch
|
||||
to allocate lots of large memory blocks when tis patch is
|
||||
found in the kernel, but it doesn't need it.
|
||||
The consequence is that, when loading the driver as a module,
|
||||
the module may tell you it's out of memory, but 'free' says
|
||||
otherwise. The reason is simple; the modules wants its memory
|
||||
contiguous, not fragmented, and after a long uptime there
|
||||
probably isn't a fragment of memory large enough...
|
||||
|
||||
The driver uses a double buffering scheme, which should really
|
||||
be an n-way buffer, depending on the size of allocated framebuffer
|
||||
and the requested grab-size/format.
|
||||
This current version also fixes a dead-lock situation during irq
|
||||
time, which really, really froze my system... :)
|
||||
|
||||
Good luck.
