v4l: vsp1: Prevent pipelines from running when not streaming

2016-11-10T15:38:57+00:00

commit e4e70a147a48618a36ae1b81c641516cb9d45993 upstream. Pipelines can only be run if all their video nodes are streaming. Commit b4dfb9b35a19 ("[media] v4l: vsp1: Stop the pipeline upon the first STREAMOFF") fixed the pipeline stop sequence, but introduced a race condition that makes it possible to run a pipeline after stopping the stream on a video node by queuing a buffer on the other side of the pipeline. Fix this by clearing the buffers ready flag when stopping the stream, which will prevent the QBUF handler from running the pipeline.

[media] rcar-fcp: Make sure rcar_fcp_enable() returns 0 on success

2016-09-15T12:02:16+00:00

When resuming from suspend-to-RAM on r8a7795/salvator-x: dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1 PM: Device fe940000.fdp1 failed to resume noirq: error 1 dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1 PM: Device fe944000.fdp1 failed to resume noirq: error 1 dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1 PM: Device fe948000.fdp1 failed to resume noirq: error 1 According to its documentation, rcar_fcp_enable() returns 0 on success or a negative error code if an error occurs. Hence fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return value to their callers. However, rcar_fcp_enable() forwards the return value of pm_runtime_get_sync(), which can actually be 1 on success, leading to the resume failure above. To fix this, consider only negative values returned by pm_runtime_get_sync() to be failures.

[media] vcodec:mediatek: Fix visible_height larger than coded_height issue in s_fmt_out

2016-08-24T14:26:41+00:00

The original code add extra 32 line to visible_height. It is incorrect, 32 line should be add to coded_height. The purpose is that user space could calcuate real buffer size needed by using coded_width * coded_height. But this method will make v4l2-compliance test fail, since g_fmt != s_fmt(g_fmt) So remove extend visible_height or coded_height, user space should just use sizeimage to get real buffer size needed Signed-off-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
