2009-03-30V4L/DVB (10827): Add support for GeoVision GV-800(S)Bruno Christo
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.

Some code was calling v4l2_video_std_construct() when all it cared about was the frame period. So make a function that just returns that and have v4l2_video_std_construct() use it. At this point there are no users of v4l2_video_std_construct() left outside of v4l2-ioctl, so it could be un-exported and made static. Change v4l2_video_std_construct() so that it doesn't zero out the struct v4l2_standard passed in. It's already been zeroed out in the common ioctl code.

2009-03-30V4L/DVB (10812): v4l2: Zero out read-only ioctls in one placeTrent Piepho
If an ioctl is read-only then the driver fills in all the fields. Lots of times drivers only care about some fields so it's best if video_ioctl2 takes care of zeroing out the entire structure before handing it to the driver. This saves code in each driver to do it and driver authors often forget. The existing memset code in some of the read-only ioctl handlers can be deleted. Convert a case statement to a single if statement. Deleted a debug line from ENUMAUDOUT that was copy-and-pasted to G_AUDOUT by mistake.

2009-03-30V4L/DVB (10811): videodev: only copy needed part of RW ioctl's parameterTrent Piepho
There are many RW ioctls() in v4l2 where userspace only supplies one or two of the first fields in the structure passed to the ioctl. The driver then fills in the rest of the fields. Instead of copying the entire structure from userspace to the kernel we only need to copy those fields that userspace is actually supposed to supply. What's more, the fields that are meant to be only be output from the driver can be zeroed out in the videodev code, in case the driver doesn't fill them all in. Many of the ioctl handlers in v4l2_ioctl do this already, but my patch does this at one common point and so all the memsets for each ioctl can be deleted. For VIDIOC_G_SLICED_VBI_CAP, which has one input field ('type') and other output-only fields, the input field is near the end of the structure instead of at the beginning. So there is still a memset in it's ioctl handler to zero out the beginning of the struct. There were a couple mistakes with the existing code: For VIDIOC_G_AUDIO the index field was preserved, but G_AUDIO is a read only ioctl so nothing is copied from userspace to preserve. For VIDIOC_G_FREQUENCY the tuner field was not preserved like it should have been. This would be a problem if there was any hardware with more than one tuner/modulator. For VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS, none of the fields were preserved even though each ioctl has several field that are supposed to be inputs to the driver! Obviously these ioctls don't get used much. The index field is needed if the driver has multiple discrete sizes/rates and other fields can be used too, e.g. if the size depends on pixel format or frame rate depends on image size for example.
