Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

3 | What is it? | ||
4 | =========== | ||
5 | |||
6 | This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV | ||
7 | boards. See http://www.semiconductors.philips.com/pip/saa7134hl for a | ||
8 | description. | ||
9 | |||
10 | |||
11 | Status | ||
12 | ====== | ||
13 | |||
14 | Almost everything is working. video, sound, tuner, radio, mpeg ts, ... | ||
15 | |||
16 | As with bttv, card-specific tweaks are needed. Check CARDLIST for a | ||
17 | list of known TV cards and saa7134-cards.c for the drivers card | ||
18 | configuration info. | ||
19 | |||
20 | |||
21 | Build | ||
22 | ===== | ||
23 | |||
24 | Pick up videodev + v4l2 patches from http://bytesex.org/patches/. | ||
25 | Configure, build, install + boot the new kernel. You'll need at least | ||
26 | these config options: | ||
27 | |||
28 | CONFIG_I2C=m | ||
29 | CONFIG_VIDEO_DEV=m | ||
30 | |||
31 | Type "make" to build the driver now. "make install" installs the | ||
32 | driver. "modprobe saa7134" should load it. Depending on the card you | ||
33 | might have to pass card=<nr> as insmod option, check CARDLIST for | ||
34 | valid choices. | ||
35 | |||

37 | Changes / Fixes | ||
38 | =============== | ||
39 | |||
40 | Please mail me unified diffs ("diff -u") with your changes, and don't | ||
41 | forget to tell me what it changes / which problem it fixes / whatever | ||
42 | it is good for ... | ||
43 | |||
44 | |||
45 | Known Problems | ||
46 | ============== | ||
47 | |||
48 | * The tuner for the flyvideos isn't detected automatically and the | ||
49 | default might not work for you depending on which version you have. | ||
50 | There is a tuner= insmod option to override the driver's default. | ||
51 | |||
52 | Card Variations: | ||
53 | ================ | ||
54 | |||
55 | Cards can use either of these two crystals (xtal): | ||
56 | - 32.11 MHz -> .audio_clock=0x187de7 | ||
57 | - 24.576MHz -> .audio_clock=0x200000 | ||
58 | (xtal * .audio_clock = 51539600) | ||
