media: venus: core: Add sdm660 DT compatible and resource struct

2021-10-21T13:26:19+00:00

Add the SDM660 DT compatible and its resource structure in order
to support the Venus IP in SDM630, SDM636, SDM660 and SDA variants.

This SoC features Venus 4.4 (HFI3XX) with only one subcore, used
for both encoding and decoding, and switched on with one main and
one subcore dedicated GDSC.

media: venus: vdec: decoded picture buffer handling during reconfig sequence

2021-10-21T13:24:48+00:00

In existing implementation, driver is freeing and un-mapping all the
decoded picture buffers(DPB) as part of dynamic resolution change(DRC)
handling. As a result, when firmware try to access the DPB buffer, from
previous sequence, SMMU context fault is seen due to the buffer being
already unmapped.

With this change, driver defines ownership of each DPB buffer. If a buffer
is owned by firmware, driver would skip from un-mapping the same.

media: venus: Handle fatal errors during encoding and decoding

2021-10-21T13:23:15+00:00

According to stateful decoder docs a fatal failure of decoding
(and encoding) could be recover it by closing the corresponding
file handle and open new one or reinitialize decoding (and encoding)
by stop streaming on both queues. In order to satisfy this
requirement we add a mechanism ins sys_error_handler and
corresponding decoder and encoder drivers to wait for sys_error_done
waitqueue in reqbuf.

- Get the min buffer count required by FW from source event change
  and use the same value to decide actual buffer count and for
  buffer size calculation.
- Setup DPB and OPB buffers after session continue incase of
  reconfig.
