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. Tested-by: Arun Iyengar Arun
