[media] v4l2: vb2: fix queue reallocation and REQBUFS(0) case · 29e3fbd8

由 Marek Szyprowski 提交于 3月 09, 2011

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.

[media] s5p-fimc: Fix G_FMT ioctl handler · 91707b8b

由 Sylwester Nawrocki 提交于 1月 15, 2011

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.

[media] s5p-fimc: Use dynamic debug · 1e004695

由 Sylwester Nawrocki 提交于 2月 23, 2011

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.

[media] s5p-fimc: Prevent hanging on device close and fix the locking · 4ecbf5d1

由 Sylwester Nawrocki 提交于 2月 23, 2011

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.

[media] s5p-fimc: fix ISR and buffer handling for fimc-capture · 8ec737ff

由 Sungchun Kang 提交于 2月 07, 2011

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.

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.
