  Implement AV1 stateless decoder for rockchip VPU981.
It decode 8 and 10 bits AV1 bitstreams.
AV1 scaling feature is done by the postprocessor.

Can you clarify ? I knew the filmgrain was, but didn't expect spatial scaling to
need it. On this aspect, I don't see any new code to let Hantro driver know that
the postproc is needed. The frame header value should be taken into account in
hantro_needs_postproc() (a per codec ops would be nice).

This is the same as V4L2_AV1_TOTAL_REFS_PER_FRAME. AV1_TOTAL_REFS_PER_FRAME is
how this is called in the spec.

This ref_count is only ever 0 and 1. Would be nicer if it was some boolean, like
"valid", or "active".

Looks like a bug_on case, only driver programming issue could cause this.

Aren't these DIV_ROUND_UP(val + 1, 8) ?

This looks like a contraction of (val + 1 + 7) / 8, so in short, another
DIV_ROUNDUP().

This looks like V4L2_AV1_REFS_PER_FRAME. Daniel, should be remove this
V4L2_AV1_NUM_REF_FRAMES ? Its redundant with V4L2_AV1_TOTAL_REFS_PER_FRAME ...

again. I'll stop pointing these out, I think you can find them.

I said I'd stop, but can't this be calculate once and saved in the reference
frame structure ?

I believe these register are read by PP when using format 0, perhaps something
nice to comment about, as they will impact the pixel produce by the post-
processor, which can be a surprising side effect. Bit 11:8 also hold
sw_bit_depth_out_minus8, but I don't know if its used for AV1, in my doc its
only used for AVS2 CODEC.

I think its good to underline that in VC8000/VC9000, some registers are shared
across multiple CODECs.

As enabling the post-proc is done by the common driver, we need a mechanism to
altern the core decisions, as we really need to enable post-proc to produce
filmgrain. Fortunatly, not applying this filter isn't visually bad, but that's
not the intent of the video author, so should not be like this by default.

2 tests (av1-1-b8-03-sizedown and av1-1-b8-03-sizeup) are only working if the postprocessor
is used. Given their names I assume it is related to scaling.
Force postprocessing is not an easy task in Hantro driver and this series is already big enough.

What I have prototype to solve this problem is to add a "need_postproc" field in context structure
but I still have issues around pixel format negotiation to solve before release it.

Hi. These are different. NUM_REF_FRAMES is the size of the "DPB" while
TOTAL_REFS_PER_FRAME is the maximum number of references a frame can
use. It just so happens that in AV1 these two are close in absolute
value (i.e. 7 vs 8).

Using VP9 as a comparison, the DPB size is still 8, but REFS_PER_FRAME
is 3 (meaning a frame can specificy LAST, GOLDEN and ALTREF values).

As this is per spec and a mere convenience, I vote for keeping it.

Ah, I was too quick on that answer :/

I see that they have REFS_PER_FRAME (7), TOTAL_REFS_PER_FRAME (8) _and_
NUM_REF_FRAMES (8), in which case it is redundant indeed. I will remove
that on v4.
