2024-03-26media: media/pci: rename VFL_TYPE_GRABBER to _VIDEOHans Verkuil
[ Upstream commit 3e30a927af3ca86f6556faf437da44ca8bcf54a4 ] 'GRABBER' is a weird name, all other types map to the /dev device names. Rename to 'VIDEO' to be consistent with the other types.

2022-04-15ivtv: fix incorrect device_caps for ivtvfbHans Verkuil
[ Upstream commit 25e94139218c0293b4375233c14f2256d7dcfaa8 ] The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was returned). The root cause was the introduction of the caps field in ivtv-driver.h. While loading the ivtvfb module would update the video_device device_caps field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps field, and that's what the overlay ioctls would look at. It's a bad idea to keep information in two places, so drop the caps field and only use vdev.device_caps.

2019-06-24media: media/pci: set device_caps in struct video_deviceHans Verkuil
Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. But this only really works if all drivers use this, so convert all pci drivers in this patch. Tested with cx88-blackbird and ivtv PVR-350.

2018-09-12media: dvb: move most compat_ioctl handling into driversArnd Bergmann
Most DVB audio and video ioctl commands are completely compatible, and are implemented by just two drivers: ttpci and ivtv. In both cases, we can use the same ioctl handler for both native and compat ioctl handling, and remove the entries from the global lookup table. In case of ttpci, this directly hooks into the file_operations structure, and for ivtv, we have to set the compat_ioctl32 method in v4l2_file_operations. For all I can tell, setting it to video_ioctl2 will still do the right thing for all commands. Note that for the VIDEO_STILLPICTURE and VIDEO_GET_EVENT commands, a translation handler in fs/compat_ioctl.c is still used. This works because the command numbers are different on 32-bit systems.

2012-10-01[media] ivtv: disable a bunch of ioctls that are invalid for the decoder VBIHans Verkuil
The VBI capture for the decoder (/dev/vbi8) is special in that it captures the VBI stream embedded in an MPEG stream that is being decoded. A lot of the ioctls that would normally be valid have to be disabled since they make no sense for such a device, and v4l2-compliance will complain about that.

V4L2_BUF_TYPE_PRIVATE was used in these driver for internal purposes. It turned out though that it wasn't used at all, so it could be removed. I know it was used in the past, but clearly later changes made this obsolete. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-09-18[media] ivtv, ivtv-alsa: Add initial ivtv-alsa interface driver for ivtvAndy Walls
This is a cut-and-paste port of the cx18-alsa driver to create an ivtv-alsa interface module for the ivtv driver. It is not actually hooked-up to the PCM stream DMA buffers from the ivtv driver yet. That will be done in a coming change, since that portion is so very different from the cx18 driver. This code has all or more of the bugs and shortcomings of the cx18-alsa interface driver: inconsistent use of itvsc->slock, ivtv-alsa-mixer.c is dead code, assumes 48 ksps regardless of the actual setting of the audio capture, problems with proper struct ivtv and struct ivtv_stream housekeeping, struct ivtv_open_id.v4l2_fh abuse, and $DIETY knows what else.
