-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.
- Pauline
