Hello,
new version of CEU after Hans' review.
Added his Acked-by to most patches and closed review comments.
Running v4l2-compliance, I noticed a new failure introduced by the way I now
calculate the plane sizes in set/try_fmt.
This is the function used to update per-plane bytesperline and sizeimage:
static void ceu_update_plane_sizes(struct v4l2_plane_pix_format *plane,
unsigned int bpl, unsigned int szimage)
{
if (plane->bytesperline < bpl)
plane->bytesperline = bpl;
if (plane->sizeimage < szimage)
plane->sizeimage = szimage;
}
I'm seeing a failure as v4l2-compliance requires buffers with both bytesperline
and sizeimage set to MAX_INT . Hans, is this expected from v4l2-compliance?
How should I handle this, if that has to be handled by the single drivers?
Apart from that, here it is the output of v4l2-compliance, with the last tests
failing due to the above stated reason, and two errors in try/set format due to
the fact the driver is not setting ycbcr encoding after it receives an invalid
format. I would set those, but I'm not sure what it the correct value and not
all mainline drivers do that.
