Workaround for the dmabuf-wayland green-frames bug (marfrit/dmabuf-modifier-triage#1). iter1 phase 2 source-read of KWin 6.6.4 + Mesa 26.0.6 ruled out the original H1/H2 hypotheses (panfrost offset handling and KWin wl_dmabuf import are clean) and matched the green tone to BT.601 limited-range YUV(0,0,0) -> RGB(0, 135, 0). Conclusion: panfrost reads zero-fill memory despite hantro having written real data — a cache-coherency / synchronization gap. V4L2 doesn't attach implicit fences (dma_resv) to CAPTURE buffers on VIDIOC_DQBUF; this gap is the same one our vb2_dma_resv RFC v2 addresses upstream. The userspace workaround is to issue DMA_BUF_IOCTL_SYNC(SYNC_START|SYNC_RW) + SYNC_END(SYNC_RW) on each EXPBUF fd before submitting to the compositor — invokes the producer driver's begin_cpu_access / end_cpu_access path, which on most ARM SoCs flushes write buffers and synchronizes coherent memory. Patch covers BOTH vaapi_dmabuf_importer (the path our test exercises via `mpv --hwdec=vaapi`) and drmprime_dmabuf_importer (for symmetry when used via `--hwdec=drmprime`). If this works, ship it; if it doesn't, hypothesis space narrows further to GPU-side cache invalidation in panfrost's kernel-mode dma_buf import path (H7). pkgrel 8 -> 9. Patch sha256 6c929bea7636b8d81b63a1275ba1d8a471fe2f249fc23509043ace6cf9b076a7.

# mpv-fourier — mpv with the fourier-umbrella patches. The first patch
|
|
# slot exists for the vo_dmabuf_wayland plane-semantics fix per
|
|
# marfrit/dmabuf-modifier-triage#1: mpv currently constructs the
|
|
# zwp_linux_buffer_params_v1 wl_protocol message with internally
|
|
# inconsistent plane semantics on V4L2 stateless decoder dmabufs (per-
|
|
# plane fds combined with single-allocation offset for plane 1), causing
|
|
# KWin to read the UV chroma plane past-EOF and render solid dark green
|
|
# on ohm (RK3566 + hantro G1 + Mali-G52). The patch is not yet written —
|
|
# this scaffold prepares the shipping path for when iter1 lands.
|
|
#
|
|
# Build configuration mirrors stock arch's mpv PKGBUILD (which builds
|
|
# successfully). Key detail: --auto-features auto is required because
|
|
# arch-meson defaults to --auto-features enabled, which makes mpv's
|
|
# platform-specific features (win32-threads, etc.) required and fails
|
|
# the build on Linux.
