Hi All,
This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs.
These patches also address the comments and feedback received from the RFC patches previously sent. I have made the necessary improvements based on the community's suggestions.
Changes in v3:
- Introduced two wrappers with explicit names to handle destroy internal
buffers (Nicolas)
- Used sub state check instead of introducing new boolean (Vikash)
- Addressed other comments (Vikash)
- Reorderd patches to have all fixes patches first (Dmitry)
- Link to v2:
https://lore.kernel.org/r/20250428-qcom-iris-hevc-vp9-v2-0-3a6013ecb8a5@quic...
Changes in v2:
- Added Changes to make sure all buffers are released in session close
(bryna)
- Added tracking for flush responses to fix a timing issue.
- Added a handling to fix timing issue in reconfig
- Splitted patch 06/20 in two patches (Bryan)
- Added missing fixes tag (bryan)
- Updated fluster report (Nicolas)
- Link to v1:

Changes sinces RFC:
- Added additional fixes to address issues identified during further
testing.
- Moved typo fix to a seperate patch [Neil]
- Reordered the patches for better logical flow and clarity [Neil,

These patches are tested on SM8250 and SM8550 with v4l2-ctl and Gstreamer for HEVC and VP9 decoders, at the same time ensured that the existing H264 decoder functionality remains uneffected.
Note: 1 of the fluster compliance test is fixed with firmware [3] [3]: https://lore.kernel.org/linux-firmware/1a511921-446d-cdc4-0203-084c88a5dc1e@...

Is it a firmware issue ?
Looks like resources set to firmware are not sufficient. I suspect, internal buffers set to firmware are less than what it requires, this can change for different VPUs. Pls check if there is any difference in internal buffer calculations between vpu3 and vpu33.
I would not recommend adding the HEVC and VP9 for 8650 unless it is functional. Please drop the HEVC and VP9 from 8650 platform data, and once it is validated, they can be added in a separate series.
Agree, I would not want to hold the enablement of HEVC and VP9 codecs. So, I will drop support for HEVC and VP9 codecs and retain only H.264 support in the 8650 caps in the next version.
Sure, thx
Neil
