Memory allocated by alloc_page() function might contain some potentially important data from other system processes. The patch adds a flag to zero the allocated page before giving it to videobuf2 (and then to userspace). Signed-off-by:

This patch fixes two minor memory leaks in videobuf2-dma-sg module. They might happen only in case some other operations (like memory allocation) failed. Signed-off-by:

This patch fixes 2 minor bugs in videobuf2 core: 1. Queue should be reallocated if one change the memory access method without changing the number of buffers. 2. In case of REQBUFS(0), the request should not be passed to the driver. Signed-off-by:

Use pix_mp member of struct v4l2_format to return a format description rather than pix. Also fill in the plane_fmt array. This is a missing bit of conversion to the multiplanar API. Signed-off-by:

Use pr_debug instead of printk so it is possible to control debug traces at runtime. E.g. to enable debug trace in file fimc-core.c use command: echo -n 'file fimc-core.c +p' > /sys/kernel/debug/dynamic_debug/control or echo -n 'file fimc-core.c -p' > /sys/kernel/debug/dynamic_debug/control to disable.

Rework the locking in m2m driver to assure proper operation on SMP systems. When job_abort or stop_streaming was called to immediately shutdown a memory-to-memory transaction video buffers scheduled for processing were never returned to vb2 and v4l2_m2m_job_finish was not called which led to hanging. Correct this and also return the unprocessed buffers to vb2 marking them as erroneous, in case the end of frame interrupt do not occur. Reported-by:

In some cases fimc H/W did not stop although there were no output buffers available. So the capture deactivation interrupt routine is modified and the state of ST_CAPT_RUN is cleared only in the LAST-IRQ call. After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame. (reference by user manual) So, S/W pointer should be increased too. Reviewed-by Jonghun Han <jonghun.han@samsung.com> Signed-off-by:

CI reset takes several seconds on some CAM, so there is no need to lock mutex all that time. Also we need not to preserve CI's reset bits in CIBUSCTRL register, they are handled automatically by FPGA. Set it to 0 explicitly in order to not reset wrong CAM. Signed-off-by:
