[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.

Experiments shows that situation when one tuner is not initialized
while other is tuned to channel causes TS errors.

[media] Fix CI code for NetUP Dual DVB-T/C CI RF card · 8af81ddb

由 Abylay Ospan 提交于 1月 02, 2011

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.
