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. Cross-reference: marfrit/kernel-agent#12.

Subject: [PATCH 1/3] media: rkvdec: vp9: Changing get_ref_buf function name to
|
|
get_ref_buf_vp9
|
|
|
|
This change is in preparation for the upcoming commits and to denote that this function is not to be confused with the similar function found in rkvdec's hevc.
