| | | | | | | | | | | | | | | | | | | | | | When stopping abnormally, a driver can't return from wait_for_completion. This patch resolved this problem by changing wait_for_completion_timeout from wait_for_completion.

| * [media] marvell-ccic: fix Y'CbCr orderingHans Verkuil2015-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various formats had their byte ordering implemented incorrectly, and the V4L2_PIX_FMT_UYVY is actually impossible to create, instead you get V4L2_PIX_FMT_YVYU. This was working before commit ad6ac452227b7cb93ac79beec092850d178740b1 ("add new formats support for marvell-ccic driver"). That commit broke the original format support and the OLPC XO-1 laptop showed wrong colors ever since (if you are crazy enough to attempt to run the latest kernel on it, like I did). The email addresses of the authors of that patch are no longer valid, so without a way to reach them and ask them about their test setup I am going with what I can test on the OLPC laptop. If this breaks something for someone on their non-OLPC setup, then contact the linux-media mailinglist. My suspicion however is that that commit went in untested.

| * | [media] coda: allocate bitstream buffer from REQBUFS, size depends on the formatPhilipp Zabel2015-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating the bitstream buffer only when the format is set allows to guarantee that at least two frames fit into the bitstream buffer. For small frame sizes a smaller bitstream buffer can be allocated. Since the bitstream buffer size now depends on the format, replace CODA_MAX_FRAME_SIZE with ctx->bitstream.size where appropriate and remove the now unused constant. Since REQBUFS can be called multiple times, but the format can't be changed unless REQBUFS 0 was called before, we can just keep the allocated context and bitstream buffers if REQBUFS is called multiple times with a non-zero buffer count.

| * | [media] v4l2_plane_pix_format: use __u32 bytesperline instead of __u16Hans Verkuil2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running v4l2-compliance tests on vivid I suddenly got errors due to a call to vmalloc_user with size 0 from vb2. Digging deeper into the cause I discovered that this was due to the fact that struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32. The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32 bit pixelformat. So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And bytesperline * height is suddenly 0 as well. While the vivid driver may be a virtual driver, it is to be expected that this limit will be hit for real hardware as well in the near future: 8k deep-color video will already reach it. The solution is to change the type to __u32. The only drivers besides vivid that use the multiplanar API are little-endian ARM and SH platforms (exynos, ti-vpe, vsp1), so this is safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vivid driver reports a range of frame intervals for non-webcams, when in fact the frame interval is fixed for those inputs as it depends on the DV timings or standard.
