2c2dc2fdc1 media: venus: helpers: Add a helper to map v4l2 ids to HFI ids
Introduce a helper to set and get profile and levels which
includes the translation between v4l2 ctrl ids and HFI ids.
The input arguments are always in v4l2 ids space.

8c91dc085b media: venus: Make debug infrastructure more flexible
Here we introduce debug prefixes for dev_dbg groups by level of
importance - Venus{Low,Med,High,FW} Enabling the particular level
will be done by dynamic debug.

For example to enable debug messages with low level:
echo 'format "VenusLow" +p' > debugfs/dynamic_debug/control

If you want to enable all levels:
echo 'format "Venus" +p' > debugfs/dynamic_debug/control

All the features which dynamic debugging provide are preserved.

0febf92369 media: venus: helpers: Done buffers per queue type
Currently calling venus_helper_buffers_done() will return buffers to
user for both capture and output queues in the same call. This is
wrong because both queues are really separate and calling
stop_streaming on one queue shouldn't return buffers for the other.
Solve this by add a new queue type argument and fix the clients of
the helper function.

ab1eda449c media: venus: vdec: handle 10bit bitstreams
Handle 10bit video streams in the decoder by using dithering, i.e
the decoder output buffers will be in 8bit format.

The runtime handling is implemented by sending v4l2 event to
userspace application, then the application should stop the
streaming on capture queue and initiate format negotiation, and
start streaming again.

4ebf969375 media: venus: introduce core selection
Presently the core (vcodec pipelines) assignment is static. Here we
introduce dynamic load balancing across the cores depending on the
current session load. The load on earch core is calculated and core
with minimum load is assigned to given instance. This will be
applicable on Venus v4 with more than one vcodec cores.

fd1ee315dc media: venus: cache vb payload to be used by clock scaling
Instead of iterate over previously queued buffers in clock
scaling code do cache the payload in instance context structure
for later use when calculating new clock rate.

This will avoid to use spin locks during buffer list iteration
in clock_scaling.

This refactors code for start/stop streaming vb2 operations and
adds a state machine handling similar to the one in stateful codec
API documentation. One major change is that now the HFI session is
started on STREAMON(OUTPUT) and stopped on REQBUF(OUTPUT,count=0),
during that time STREAMOFF(CAP,OUT) just flush buffers but doesn't
stop the session. The other major change is that now the capture
and output queues are completely separated.

f012b23d64 media: venus: implementing multi-stream support
This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.

Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.

Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).

The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

e69b987a97 media: venus: reimplement decoder stop command
This addresses the wrong behavior of decoder stop command by
rewriting it. These new implementation enqueue an empty buffer
on the decoder input buffer queue to signal end-of-stream. The
client should stop queuing buffers on the V4L2 Output queue
and continue queuing/dequeuing buffers on Capture queue. This
process will continue until the client receives a buffer with
V4L2_BUF_FLAG_LAST flag raised, which means that this is last
decoded buffer with data.

af2c3834c8 [media] media: venus: adding core part and helper functions
* core.c has implemented the platform driver methods, file
operations and v4l2 registration.

 * helpers.c has implemented common helper functions for:
   - buffer management

   - vb2_ops and functions for format propagation,

   - functions for allocating and freeing buffers for
   internal usage. The buffer parameters describing internal
   buffers depends on current format, resolution and codec.

   - functions for calculation of current load of the
   hardware. Depending on the count of instances and
   resolutions it selects the best clock rate for the video
   core.

 * firmware loader
