Reference the 3 patches imported in the previous commit under the
scope-tagged patch list. Apply order is strict (0001 → 0002 → 0003).
Verified 2026-05-18 via the arch_vp9_test extlinux boot on ampere:
- VP9F enumerates on rkvdec /dev/video2
- kdirect decode bit-exact vs libavcodec SW reference at -ss 30
- libva decode (firefox/chromium-style consumer) also bit-exact
- vainfo lists VAProfileVP9Profile0 (iter38 multi-device probe auto-picks)
- All three paths agree on sha

Removes VP9 from the "explicitly not included" comment block — issue
#12 closes with this change.
Also: AV1 stays out-of-scope per issue #6 ask 3 (kernel side fine via
the existing av1-vpu-dec node; backend just needs the 4th-fd
generalization tracked in libva-v4l2-request-fourier#2).
The next linux-ampere-fourier package rebuild from this manifest
will pick up VP9 automatically; ampere's running
7.0.0-rc3-vp9-test+ kernel already has these patches via the
operator's manual build session today.
Three patches from D.V.A.B. Sarma adding VP9 decode support to the
VDPU381 variant of rkvdec (RK3588 generation). Combined ~1500 LOC,
5 new files in drivers/media/platform/rockchip/rkvdec/.
Provenance: github.com/dvab-sarma/android_kernel_rk_opi branch
add-rkvdec-vdpu381-vp9-v8. Collabora's blog cites the work but it
hasn't reached linux-media patchwork yet (Collabora: "v1 series
needs to be sent for review soon"). Casanova's underlying
VDPU381/VDPU383 H.264+HEVC base IS in mainline 7.0 release.
Tested by author on Orange Pi 5 Pro (RK3588) with AOSP 16 + FFMPEG,
Profile 0 + Profile 2.
Tested in our fleet 2026-05-18: cherry-picks cleanly on top of
ampere-minimal-devices, full kernel build (KERNELRELEASE
7.0.0-rc3-vp9-test+) succeeds clean with GCC 16.1.1. Image + DTB +
modules + initramfs installed under -vp9-test+ suffix on ampere
without touching the running -devices+ kernel; new extlinux label
arch_vp9_test added (default unchanged at arch_devices). End-to-end
VP9 decode verification pending operator reboot into the new label.
Patches NOT yet referenced from fleet/ampere.yaml — that bump is
the operator's call (manifest preamble currently scopes VP9 out per
issue #6). Once verified, ampere.yaml can add these three under the
scope-tagged patch list in apply order 0001→0002→0003.
