Roll out libva-v4l2-request-fourier on fresnel (Pinebook Pro / RK3399)
with broader codec scope than ohm-side libva-multiplanar:
- H.264 + HEVC + VP9 via the rkvdec block (/dev/video3)
- MPEG-2 + VP8 via the hantro-vpu-dec block (/dev/video5)
Topology: peer campaign, independent 8(+1) loop. fresnel-fourier
results do not gate libva-multiplanar Phase 8 closes. Code-side work
in the shared fork (../libva-multiplanar/libva-v4l2-request-fourier/)
lands per Phase 2 source-read of each iteration.
Phase 0 task 1: recover fresnel from the SDDM greeter crash-loop
(per ~/.claude/plans/dynamic-forging-piglet.md). Recovery is bookkept
inside this campaign's Phase 0, not as an out-of-band prereq.
Verified 2026-05-07 via SSH:
- linux-eos-arm 6.19.9-99 has CONFIG_FTRACE=y + CONFIG_FUNCTION_TRACER=y
+ CONFIG_DYNAMIC_FTRACE=y + CONFIG_TRACING=y. /sys/kernel/tracing/
populated. No kernel rebuild needed for trace work.
- /dev/video3 = rkvdec (NV12 capture, MPLANE).
- /dev/video5 = hantro-vpu, card type rockchip,rk3399-vpu-dec.
