Phase 7 verification on fresnel (kernel 7.0-14 / linux-fresnel-fourier).
C1 vainfo enumeration: PASS — VAProfileH264High10 + VAProfileHEVCMain10
both listed; iter38 baseline 10 profiles intact at 12 total.
C5 iter38 5/5 baseline preserved: PASS — H.264 / HEVC / VP9 / VP8 /
MPEG-2 all libva == kdirect bit-exact, no regression from iter39
backend changes.
C2 Hi10P bit-exact vs kdirect: N/A — kdirect ALSO fails with EINVAL
(0 bytes output). The kernel ctrl table advertises Hi10P + NV15
CAPTURE but RK3399 HW doesn't actually decode 10-bit H264. Verified:
S_FMT(CAPTURE, NV15) succeeds; decode submits cleanly; CAPTURE buffer
returns all-zero. xxd 64 bytes of 0x00. SW reference has 222 unique
luma bytes.
C3 Main10 bit-exact vs kdirect: untested — system x265 is 8-bit-only
build, no kvazaar/x265-hbd in Arch repos, no Main10 sample downloaded
successfully. Same kernel-vs-HW caveat may apply.
Two backend fixes landed during Phase 7 (both pushed to gitea master):
a13215d — skip pre-S_FMT NV15 CAPTURE format probe (rkvdec only
advertises NV15 AFTER S_FMT(OUTPUT) + S_EXT_CTRLS(SPS))
63fed87 — advertise P010 unconditionally in QueryImageFormats
(ffmpeg-vaapi queries before CreateContext fires; gating
on is_10bit hid the format from early consumers)
Without these the 10-bit decode pipeline can't even start. With them
it reaches the kernel cleanly.
Memory entry filed:
feedback_rk3399_h264_hi10p_advertised_not_functional.md
(kernel ctrl table necessary but NOT sufficient — always cross-check
with kdirect before treating a profile as truly HW-supported)

Adds the iter39 sub-profile (H264 Hi10P + HEVC Main10) FR landing
materials and resumption sequence to the campaign repo.
- phase4_iter39_subprofile_plan.md: full Phase 4 plan with Phase 5
sonnet-architect review amendments folded in. Documents the
Option A/B/C/D scope tree, the locked Option C choice (full NV15→P010
userspace unpack), the LOC breakdown (~180), and the test plan.
- phase7_iter39_test_rig.sh: end-to-end test script for fresnel. Encodes
Hi10P + Main10 fixtures, runs libva vs kdirect bit-exact comparison
(both via `-vf hwdownload,format=p010le` to normalize the NV15 stride
difference between paths), SSIM_Y check vs SW reference, and verifies
the iter38 5/5 baseline still holds.
- PRE_COMPACT_HANDOFF.md: TL;DR table row for iter39 (committed
pending validation), Phase 7 resumption sequence, internals-summary
for future-session resumption.
Backend tip: `662f887` (iter39 α-31) + `8746690` (unpack self-test) on
gitea master. Self-test passes on noether x86_64; compile-test clean on
boltzmann aarch64 native; self-review of commit vs Phase 5 amendments
APPROVED. Phase 7 actual decode test blocked on fresnel power-on.
