media: siano: fix memory leak of debugfs members in smsdvb_hotplug

2020-12-30T10:51:12+00:00

[ Upstream commit abf287eeff4c6da6aa804bbd429dfd9d0dfb6ea7 ] When dvb_create_media_graph fails, the debugfs kept inside client should be released. However, the current implementation does not release them. Fix this by adding a new goto label to call smsdvb_debugfs_release.

media: v4l2-tpg: add support for new pixelformats

2019-07-30T16:16:45+00:00

Several new variations of RGB444, RGB555 and RGB32 were added. Add support for these. This is the list of new pixelformats: V4L2_PIX_FMT_RGBX444 V4L2_PIX_FMT_RGBA444 V4L2_PIX_FMT_XBGR444 V4L2_PIX_FMT_ABGR444 V4L2_PIX_FMT_BGRX444 V4L2_PIX_FMT_BGRA444 V4L2_PIX_FMT_RGBX555 V4L2_PIX_FMT_RGBA555 V4L2_PIX_FMT_XBGR555 V4L2_PIX_FMT_ABGR555 V4L2_PIX_FMT_BGRX555 V4L2_PIX_FMT_BGRA555 V4L2_PIX_FMT_RGBX32 V4L2_PIX_FMT_BGRX32 V4L2_PIX_FMT_RGBA32 V4L2_PIX_FMT_BGRA32 Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vb2-dc: skip CPU sync in map/unmap dma_buf

2019-07-23T15:46:27+00:00

This is rougly equivalent to ca0e68e21aae (drm/prime: skip CPU sync in map/unmap dma_buf). The contig memory allocated is already device coherent memory, so there is no point in doing a CPU sync when mapping it to another device. Also most importers currently cache the mapping so the CPU sync would only happen on the first import, so we are better off with not pretending to do a cache synchronization at all. This gets rid of a lot of CPU overhead in uses where those dma-bufs are regularily imported and detached again, like Weston is currently doing in the DRM compositor.

media: vb2: reorder checks in vb2_poll()

2019-07-23T12:44:45+00:00

When reaching the end of stream, V4L2 clients may expect the V4L2_EOS_EVENT before being able to dequeue the last buffer, which has the V4L2_BUF_FLAG_LAST flag set. If the vb2_poll() function first checks for events and afterwards if buffers are available, a driver can queue the V4L2_EOS_EVENT event and return the buffer after the check for events but before the check for buffers. This causes vb2_poll() to signal that the buffer with V4L2_BUF_FLAG_LAST can be read without the V4L2_EOS_EVENT being available. First, check for available buffers and afterwards for events to ensure that if vb2_poll() signals POLLIN | POLLRDNORM for the V4L2_BUF_FLAG_LAST buffer, it also signals POLLPRI for the V4L2_EOS_EVENT.

media: media/pci: don't set description for ENUM_FMT

2019-07-22T18:40:32+00:00

The V4L2 core sets the description for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: media/pci: set device_caps in struct video_device

2019-06-24T18:57:12+00:00

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.
