Subject: Re: [PATCH v2 0/5] media: rkvdec: Enable multi-core support
Date: Sat, 14 Nov 2026 04:50:12 -0000 [thread overview]
Message-ID: <179463181227.3521962.172866405609790742@gmail.com> (raw)
In-Reply-To: <20260810-rkvdec-multicore-v2-0-986f89d22cdc@collabora.com>
Hi Detlev,
Tested on an Orange Pi 5 (RK3588S), v7.3 with rga/ and rkvdec/ synced
to the 7.4 merge window, together with Sven's RGA multi-core v2 (whose
patch 7 already carries the export of your 3/5; your 4/5 needed a
small hand merge there). Decode-only, 4K HEVC streams in parallel:
1/2/4 streams 105/202/206 fps total (single core: 105/111/129).
4 parallel 4K HEVC and 2 parallel 4K H.264 streams are bit-exact
against FFmpeg's software decoder, and both cores take interrupts.
v4l2-compliance is unchanged, with no IOMMU faults or timeouts. Not
tested: 8K, long runs, runtime PM idle cycling, unbind under load.
