[PATCH 0/4] media: rkvdec: Add VP9 support for VDPU381 variant

[Venkata Atchuta Bheemeswara Sarma Darbha]

Hi All,
This patch series adds the initial VP9 support for VDPU381 present in rk3588.

VDPU381 supports VP9 Profile 0 and Profile 2 up to 7680x4320 at 30fps.

Tested with fluster (suite : VP9-TEST-VECTORS, decoder: GStreamer-VP9-V4L2SL-Gst1.0).
The 224/305 score has been reproduced independently on three RK3588 boards
across three kernel bases: Orange Pi 5 Pro (RK3588S, 7.2.0-rc3),
Orange Pi 5 Plus (RK3588, 7.0) and Radxa Rock 5B+ (RK3588, 7.1).

Most of the remaining failures fall into a few known categories:

- All vp90-2-02-size-*.webm variants where either dimension is
  smaller than 64 pixels fail because the hardware does not support
  frames smaller than 64x64:

- vp90-2-05-resize.ivf, vp90-2-18-resize.ivf and all
  vp90-2-21-resize_inter_*.webm variants fail. These streams change
  resolution mid-stream on a non-keyframe, and a reference frame
  from before the resize ends up unavailable by the time it's
  needed again. This is being actively looked into:

- vp91-2-04-yuv422.webm
  vp91-2-04-yuv444.webm
  fail because the hardware does not support the format these
  streams use (4:2:2/4:4:4), only 4:2:0.

The base vdpu381 VP9 driver support was introduced by me. Profile 2 support
was added by Igor Paunovic. Francesco Saverio Pavone fixed bugs in
the segmentation map size calculation and in the altref vertical
scale factor. Igor Paunovic also fixed a decoded-frame stride bug, aligning
bytesperline to 64 bytes in rkvdec_fill_decoded_pixfmt().
