Subject: Re: [PATCH v2 0/5] media: rkvdec: Enable multi-core support
Date: Sat, 14 Nov 2026 05:01:04 -0000 [thread overview]
Message-ID: <179463246494.3611640.18079808669048880957@gmail.com> (raw)

Hi Detlev,
One more data point for this series. On top of it I have one stream
decoded on both RK3588 cores at once through the CCU, as the Rockchip
BSP does ("soft CCU": each frame goes to the idle core, and the CCU
holds back reference reads until the other core has written them).
For a single 4K stream that gives HEVC 227 fps instead of 130 and
H.264 121 fps instead of 67, bit-exact. It needs two v4l2-mem2mem
additions, so that the next job of a context can be scheduled while
the previous one is still decoding.
I'll post it as an RFC once this series has settled, so it can be
rebased on what lands. The code was developed with Claude (Anthropic);
I review and test every change.
Arun
