V4L/DVB (10827): Add support for GeoVision GV-800(S)
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: ... 02:00.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:00.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:04.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:04.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:08.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:08.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:0c.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:0c.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 02:00.0 0400: 109e:036e (rev 11) Subsystem: 800a:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdfff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:00.1 0480: 109e:0878 (rev 11) Subsystem: 800a:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:04.0 0400: 109e:036e (rev 11) Subsystem: 800b:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffd000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:04.1 0480: 109e:0878 (rev 11) Subsystem: 800b:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffc000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:08.0 0400: 109e:036e (rev 11) Subsystem: 800c:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffb000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:08.1 0480: 109e:0878 (rev 11) Subsystem: 800c:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdffa000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 02:0c.0 0400: 109e:036e (rev 11) Subsystem: 800d:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdff9000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 Kernel modules: bttv 02:0c.1 0480: 109e:0878 (rev 11) Subsystem: 800d:763d Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at cdff8000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data <?> Capabilities: [4c] Power Management version 2 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.
