marfrit	25610930ad	ffmpeg-v4l2-request-fourier: export ff_h264_set_mb_inspect_cb (0016 amend, PKGREL 15) ... The 0016 patch declared ff_h264_set_mb_inspect_cb in h264dec.h and defined it in h264_mb.c, but didn't touch libavcodec/libavcodec.v. FFmpeg's default version script exports only `av_*`, `avcodec_*`, `avpriv_*`, and `avsubtitle_free`; everything else is hidden as LOCAL behind a `*` glob. Result: `nm -D libavcodec.so.62 | grep ff_h264_set_mb_inspect_cb` returned nothing → dlsym() returned NULL. Static-link CLI consumer (daedalus_decode_h264) was unaffected because static linking doesn't care about symbol visibility. The daedalus-v4l2 daemon shadow_decoder path (PR-Q3a.1) dlopens libavcodec.so.62 and resolves the callback via dlsym — that needs the symbol exported. Fix: add ff_h264_set_mb_inspect_cb to the global list in libavcodec/libavcodec.v. Single-line addition to the 0016 patch. Mirrored across the arch/ + debian/ patch trees. PKGREL bump 14 → 15, changelog entry added (debian side). PKGBUILD pkgrel bumped on arch side too. No behaviour change to the decode path: the callback is still opt-in via the H264Context function pointer; only consumers that have explicitly installed a callback pay the one-load-one-branch cost per MB. dejavu-check: this is fixing the existing 0016 observation-hook to actually work as a dlsym intercept (the architectural shape the patch was designed for). NOT adding new per-kernel substitution. Same shape, same patch number, same intent. Just hiding/exporting plumbing.

claude-noether	ea99dc8e27	ffmpeg-v4l2-request-fourier: preserve sl->mb for inspection callback (0017) ... Companion to 0016 (PR #106). Adds a coefficient side buffer in H264Context, populated at the start of ff_h264_hl_decode_mb with a single memcpy from sl->mb BEFORE IDCT-add zeros it. The existing post-pixel-work callback (still in 0016) can now read: - h->mb_inspect_coeffs = pre-IDCT coefficients (this patch) - h->cur_pic.f->data = post-pixel-work pre-deblock reconstruction and derive P = pixels − IDCT(C) for daedalus-decoder's frame-major dispatch in PR-A3+. Memcpy gated on (h->mb_inspect_cb != NULL). Zero cost when no consumer is registered. Side buffer = 16 * 48 int16 = 1536 bytes (matches the 8-bit half of sl->mb's int16_t[16 * 48 * 2] declared size; high-bit-depth uses the upper half — not preserved here since the daedalus-decoder consumer is 8-bit-only). Single-threaded decode assumed at the consumer side (avctx->thread_count = 1). Multi-slice / multi-threaded streams would race on the single side buffer — explicit limitation of the inspection mechanism, future extension would put per-slice buffers in H264SliceContext. Verified: patches 0016 + 0017 apply cleanly and build in sequence against the Kwiboo v4l2-request-n8.1 fork at the pinned commit b57fbbe5. ff_h264_set_mb_inspect_cb symbol exported as before. Wired into arch PKGBUILD + debian build-deb.sh patch sequence. pkgrel bumped 13 → 14.

claude-noether	87cbb9b70a	ffmpeg-v4l2-request-fourier: per-MB inspection callback for H.264 (0016) ... Adds 0016-h264-mb-inspect-callback.patch to the FFmpeg fork. Adds an opt-in callback fired by ff_h264_hl_decode_mb after the existing pixel work, for tools that need per-MB visibility into H.264 decode. API: typedef void (*ff_h264_mb_inspect_cb)(void *opaque, const struct H264Context *h, int mb_x, int mb_y); void ff_h264_set_mb_inspect_cb(AVCodecContext *avctx, ff_h264_mb_inspect_cb cb, void *opaque); Two new fields appended to H264Context (internal struct, declared in h264dec.h not h264.h, no ABI surface to non-libavcodec callers). Callback fires post-pixel-work for every MB in coded order; receives const H264Context* so it can inspect any state (slice ctx via h->slice_ctx, reconstructed pixels via h->cur_pic.f->data[plane], etc.). Default (cb==NULL): zero behaviour change, one load + one branch per MB in the decoder hot path. Shape distinction: per-MB observation, NOT per-kernel function-pointer hijack (the 0003-0014 substitution-arc pattern that PR #105 reverted + daedalus-fourier PR #37's measurement-correction architecturally retired). Per-block synchronous Vulkan dispatch from libavcodec is non-competitive; per-MB CPU-side observation feeding a per-frame daedalus-decoder batch submit is the right shape (frame-major UMA dispatch verdict, memory: dejavu).

claude-noether	f4047f3145	ffmpeg-v4l2-request-fourier: revert ctx flip — PR #36 was a measurement artifact (0015) ... Reverts the no_qpu → qpu-capable ctx flip that landed via patch 0014 (marfrit-packages PR #104). PR #104 was justified by daedalus-fourier PR #36's "QPU 4.30x faster than CPU NEON" bench result. That number was a measurement artifact: v3d_runner.read_spv() did a bare cwd-relative fopen() with no path search, so when the bench was run from the source dir (as in PR #36), the SPVs at $builddir/v3d_*.spv were not found, every QPU dispatch returned -1 fast, and the bench loop timed the failure path. daedalus-fourier PR #37 fixes the SPV search + bench preflight. Corrected numbers on hertz (Pi 5 V3D 7.1): kernel CPU ns/op QPU ns/op winner IDCT 4x4 luma 10.75 217.63 CPU 20.24x IDCT 8x8 luma 29.69 785.94 CPU 26.47x Deblock luma_v 17.63 467.42 CPU 26.51x Deblock luma_h 38.30 498.53 CPU 13.02x qpel mc20 (8x8) 30.17 1300.44 CPU 43.10x qpel mc02 (8x8) 17.69 1363.40 CPU 77.08x qpel mc22 (8x8) 71.60 1948.37 CPU 27.21x 1080p sum: CPU 5.57 ms vs QPU 123.54 ms — QPU 22x SLOWER. Until daedalus QPU dispatch overhead is actually competitive (separate multi-task effort tracked on the daedalus-fourier side), libavcodec.so substitution must stay on daedalus_ctx_create_no_qpu() so the host processes (firefox-fourier RDD, mpv-fourier, daedalus_v4l2_daemon) don't pessimize their H.264 decode path.

claude-noether	9c70ffffe7	ffmpeg-v4l2-request-fourier: flip libavcodec daedalus ctx no_qpu → qpu-capable (0014) ... (Renumbered from 0013 — PR #102 landed 0013-h264-deblock-chroma-intra while this PR was open, so the next free slot is 0014.) Patches 0003 (IDCT 4x4) and 0007 (qpel mc20) created the libavcodec.so process-global daedalus_ctx via daedalus_ctx_create_no_qpu(). Rationale at the time: cycle 6/9 had only CPU NEON paths, so a QPU-capable ctx would have meant pointless Vulkan init in every host process. Two things changed since: 1. Every H.264 hot-path primitive now has a V3D7 compute shader. IDCT 4x4/8x8 + 8 deblock variants (luma+chroma × V+H × inter+intra) + 30 qpel positions. See daedalus-fourier PRs #28-#35. 2. Dispatch overhead has been hammered down — buffer pool in v3d_runner + persistent command buffer. daedalus-fourier PR #36 bench on hertz (Pi 5 V3D 7.1, 30 iters x 5 warmup): 1080p worst-case sum (IDCT4 + deblock luma + qpel mc22): CPU NEON only: 5.57 ms QPU only: 1.30 ms (CPU/QPU sum ratio = 4.30x) PR #10's CPU-4x-faster-than-QPU verdict (which justified the original no_qpu ctx choice) is reversed by ~17x. This commit adds 0014-h264-ctx-qpu-capable.patch which flips both H.264 TUs (h264_idct_daedalus.c, h264_qpel_daedalus.c) from daedalus_ctx_create_no_qpu() to daedalus_ctx_create(). daedalus_ctx_create() probes for a usable Vulkan device and falls back to no_qpu mode if unavailable, so this is safe on hosts without V3D (x86 build runners, Debian aarch64 builders without renderD, etc.). Hosts WITH V3D (Pi 5 deployment targets) now route the H.264 hot-path through V3D compute instead of CPU NEON.

marfrit	e323aa2316	mesa-panvk-bifrost r9: bump maxImageDimension3D to 2048 (iter22, unblocks Dawn/WebGPU) ... Adds 0008-panvk-bifrost-bump-max-image-dim-3d-for-dawn.patch. Two-hunk patch: Hunk 1: Bumps maxImageDimension3D from 512 to 2048 on Bifrost (PAN_ARCH 7..10). Surfaced by panvk-bifrost-perf-measurement iter1 spike: Brave's WebGPU/Dawn detects panvk-bifrost as a Vulkan adapter on Mali-G52 r1 MC1 but rejects it because the advertised limit is below WebGPU's 2048 minimum (per third_party/dawn/src/dawn/native/vulkan/PhysicalDeviceVk.cpp:746). This is the actual unblock for the campaign's stated motivator — Chromium GPU process Vulkan boot on PineTab2 / Bifrost SBCs. Per Vulkan 1.3 spec §43.1, maxImageDimensionXD is the upper bound on any creatable image; per-format limits MAY be smaller. On PAN_ARCH<=10 the per-format limit caps at ~1023 per axis for RGBA8 within the 4 GB max_img_size_B address constraint. Apps trying 2048^3 with thick formats hit the per-format limit at image-create — per-spec behavior. Hunk 2: Removes three asserts in get_max_3d_image_size() that encoded the wrong invariant (per-format >= basic), opposite of what the Vulkan spec mandates. The asserts were release-mode-masked via NDEBUG, but debug builds would abort the first time Dawn (or any client) called vkGetPhysicalDeviceImageFormatProperties on a 3D image format. Surfaced by Phase 5 2nd-model review. Verified on PineTab2 (Mali-G52 r1 MC1, PAN_ARCH 7): - vulkaninfo: maxImageDimension3D = 2048 - Brave/Dawn: "Insufficient Vulkan limits" warning eliminated; adapter accepted for WebGPU. - CTS regression: dEQP-VK.api.copy_and_blit.core.image_to_image.3d_images.* 6/6 Pass (unchanged from r7 baseline). Phase 5 (2nd-model) review: APPROVE WITH CHANGES — both changes applied (release-mode + debug-mode assert exposure addressed by removing the wrong-invariant asserts). Note on numbering: r8 was attempted (KHR_depth_clamp_zero_one trim) but abandoned mid-Phase-3 when it surfaced that 5 more post-1.3.10 KHR extensions are advertised — surgically false-gating all of them would risk undoing r1's KHR_robustness2 work for Chromium Dawn.

The fourier dispatches were exposed in PR #11 (DEFINE_INTRA_DISPATCH macro generates the public daedalus_dispatch_h264_deblock_chroma_*_intra symbols + recipe wrappers). Re-architects the chroma init: v_loop_filter_chroma_intra was previously assigned unconditionally to the NEON variant (which works for both 4:2:0 and 4:2:2). We now assign it INSIDE both branches of the chroma_format_idc conditional — 4:2:0 picks daedalus, 4:2:2 keeps NEON. No regression for 4:2:2 streams. Same NEON-to-NEON via recipe shape as 0010 luma intra.

marfrit	c14c22f942	mesa-panvk-bifrost r7: fix XFB store channel-extract for packed varyings (iter19) ... Adds 0007-panvk-bifrost-xfb-component-base-fix.patch — eliminates a reliable SIGSEGV in vkCreateGraphicsPipeline whenever an XFB-bound vertex output is declared with non-zero `layout (component=N)`. Surfaced by dEQP-VK.transform_feedback.simple.holes_vert (Mali-G52 r1 MC1, PAN_ARCH 7). Backtrace lands 11 frames into libvulkan_panfrost.so called from vkt::TransformFeedback::TransformFeedbackHolesInstance:: iterate. Root cause: iter17's lower_xfb_output_iter17 (and upstream pan_nir_lower_xfb, which has the identical `// TODO`) computes the source-channel mask as `mask << channel_idx`, where channel_idx is the varying-location component (0..3) but src only contains channels starting at nir_intrinsic_component(intr). For a scalar declared component=2, the lowering computed `mask << 2` against a 1-component src — out-of-range; the malformed nir_def segfaulted in downstream NIR constant-folding (nir_constant_expressions.c::evaluate_*). Fix translates channel_idx to source-channel space by subtracting nir_intrinsic_component(intr) before shifting the mask, and replaces the elided release-mode asserts with explicit release-mode guards (closes the same elision class as the original bug). Verified on PineTab2 (Mali-G52 r1 MC1, PAN_ARCH 7) against vulkan-cts 1.3.10.0: - holes_vert / holes_extra_draw_vert no longer SIGSEGV (now Fail on color-check; that is a separate iter20 finding). - basic_*: 36/36 Pass. depth_clip_*: 1 Pass + 4 NotSupported. lines_or_triangles*: 16 NotSupported. 0 Fail across the set. Caveat (not regressions): max_output_components_64/_128/_256 were never reached on the r5 sweep — watchdog killed transform_feedback after the holes_vert crash. With this fix in place, they now run and surface their own pre-existing coredumps, confirmed on shipped r6 baseline too. iter20+ territory. Phase 5 (2nd-model) review: APPROVE WITH CHANGES (non-blocking). Changes applied: release-mode defensive guards on both preconditions plus a dispatcher-side comment clarifying the i*2+j semantics.

Source-of-truth: git.reauktion.de/marfrit/aish, tag v0.1.0 (tarball sha256 9ebc3939e028832e39391ae33efacb5ec9bcd99d123cbc8ca1cd6ca9a640b5b5). The arch and debian recipes mirror the lmcp pattern (pure-Lua any-arch package, no makefile, install copies modules directly): arch/aish/PKGBUILD — depends=(luajit readline curl) debian/aish/build-deb.sh — pure dpkg-deb, SOURCE_DATE_EPOCH pinned debian/aish/debian/{control,changelog,copyright} Install layout, matching what main.lua's script-dir-relative package.path expects after the wrapper execs `luajit /usr/share/lua/5.1/aish/main.lua`: /usr/bin/aish ← bin/aish wrapper /usr/share/lua/5.1/aish/{main,broker,context,executor,history, mcp,renderer,repl,router,safety,secrets}.lua /usr/share/lua/5.1/aish/ffi/{curl,libc,pty,readline}.lua /usr/share/lua/5.1/aish/vendor/dkjson.lua /usr/share/doc/aish/{README.md,LICENSE,examples/config.lua} CI: two new jobs in .gitea/workflows/build.yml at the end of file. aish-any chains needs:lmcp-debian (parallel-DAG with claude-his-any, serialized via the shared arch-aarch64 runner — avoids needless wait through the unrelated fourier stack). aish-debian chains needs:aish-any.

Folded in two findings before commit: switched needs: from mpv-fourier-aarch64 to lmcp-debian (cleaner DAG, faster cold-build wall clock), removed the dead Build-Depends: debhelper- compat line from debian/aish/debian/control (build-deb.sh doesn't use debhelper).

ARM's own libmali r51p0 driver (BXODROIDN2PL, 2024-08) lists VK_EXT_legacy_dithering in its Vulkan extension string table, confirming the feature is shipped by ARM for Mali-G52-class hardware. Follow-up out of scope: the 94 renderpass-dithering tests show as NotSupported on both r5 and r6 — there's a separate panvk-side prereq the dEQP harness checks (likely a specific format-feature combination).

Cycle 9 of the daedalus-v4l2#11 step 2 substitution arc; closes the 4-cycle libavcodec.so substitution sequence: cycle 6 (PR #76) H.264 IDCT 4x4 done cycle 7 (PR #85) H.264 IDCT 8x8 done cycle 8 (PR #86) H.264 luma-v deblock done cycle 9 (this) H.264 qpel mc20 Bumps daedalus-fourier pin d87239d → 209a421 (PR #2 — public API gains daedalus_recipe_dispatch_h264_qpel_mc20 + DAEDALUS_KERNEL_H264_QPEL_MC20). Verdict per docs/k9_h264qpel_mc20.md: CPU NEON. Per-block 7.6 ns at 131 Mblock/s gives 135× margin over 30 fps 1080p; QPU dispatch floor at ~250 ns makes any V3D shader strictly worse. Substitution is plumbing-only — same daedalus_ctx_create_no_qpu pthread_once shape the cycles 6/7/8 shims already own (kept SEPARATE from the H264DSP shim's ctx because H264QPEL is its own libavcodec Makefile module and link order does not guarantee a single .o owns the ctx symbol; one extra ~µs init per process, paid lazily on first MC call). Other H.264 luma MC variants (mc02, mc11, mc22 etc.) and the 16x16 size tier stay on the in-tree NEON .S code per the cycle-9 phase-1 rationale (mc20 8x8 is representative; remaining variants would multiply recipe-lookup overhead without changing the substrate verdict).

marfrit	5c69460722	ffmpeg-v4l2-request-fourier: restore AV_CODEC_FLAG_LOW_DELAY in H.264 decoder ... FFmpeg 8.x dropped the H.264 decoder's low_delay code path — AV_CODEC_FLAG_LOW_DELAY no longer prevents h264_select_output_frame from running the display-order DPB output queue. The daedalus-v4l2 daemon's `ctx->flags |= AV_CODEC_FLAG_LOW_DELAY` at daemon/src/decoder.c:202 has been a silent no-op since the SONAME 61→62 jump landed in reauktion/daedalus-v4l2 PR #16; on Firefox YouTube this re-introduced the 2-1-4-3 B-frame pair-swap that PR #12's daemon flag was supposed to prevent. Fix lives in libavcodec, not the daemon: restore the documented LOW_DELAY semantics so the daemon (and any other V4L2-stateless- style consumer) keeps the one-frame-per-send_packet decode-order output contract it already declares. ## Patch 0006-h264-restore-low-delay.patch touches libavcodec/h264_slice.c: - h264_select_output_frame: early-exit when LOW_DELAY is set. Emit the just-decoded picture as next_output_pic, mirror the corruption / recovery-point tracking the main path performs, skip delayed_pic[] / POC reorder machinery entirely. - h264_field_start: suppress the SPS-driven `has_b_frames = sps->num_reorder_frames` clobber when LOW_DELAY is set. Without this the per-slice bitstream_restriction_flag re-pickup would reintroduce a nonzero reorder buffer mid-stream even after the daemon set has_b_frames=0 at avcodec_open2. ## Why not daemon-side A daemon SPS-rewrite (`num_reorder_frames=0`) was considered but rejected: it works only for the daemon's reconstructed SPS NAL, not for any in-band SPS the daemon dlopens libavformat to parse in other code paths. Restoring documented FFmpeg flag semantics is the smaller, more durable change and keeps the daemon interface stable. ## Packaging - PKGREL/pkgrel bump to 9. - No new build-deps, no Depends change. - Substitution arc cycles 6/7/8 unchanged. ## Refs - reauktion/daedalus-v4l2#11 / #12 (LOW_DELAY half-measure on daemon side, originally landed against FFmpeg 7.x). - daemon/src/decoder.c:202 (`ctx->flags |= AV_CODEC_FLAG_LOW_DELAY` for H.264 only — unchanged, but now actually has effect again).	2026-05-22 14:20:37 +02:00

Patches libavcodec/aarch64/h264dsp_init_aarch64.c to wire c->v_loop_filter_luma to the new shim. - arch/PKGBUILD + debian/build-deb.sh: append patch + bump pkgrel/PKGREL to 8. - No new build-deps, no Depends change, no daedalus-fourier rev — the d87239d pin already exposes daedalus_recipe_dispatch_h264_deblock_luma_v. ## Why Cycle 8 is marked "CPU primary; QPU opportunistic" in the daedalus- fourier API docstring. Per the hybrid substrate philosophy ("if there's a coprocessor, use it") we eventually want the QPU opportunism active here. But the libavcodec.so context is process-global and shared with cycles 6/7 via pthread_once, and it uses daedalus_ctx_create_no_qpu deliberately to avoid implicit Vulkan init in arbitrary host processes (Firefox content, mpv-fourier, ffmpeg-fourier CLI, ...). Switching to daedalus_ctx_create here without a feature flag would be a footgun. So cycle 8 lands as plumbing-only NEON-by-recipe substitution for now; opportunistic QPU enablement is a separate follow-up that adds a DAEDALUS_FOURIER_ENABLE_QPU env var or equivalent. ## Scope NOT covered - Intra (bS=4) loop filter c->v_loop_filter_luma_intra — daedalus's daedalus_h264_deblock_meta only covers the non-intra path. - Horizontal-edge variant c->h_loop_filter_luma — separate kernel (not yet in daedalus-fourier API). - Chroma loop filters — separate kernels. - Bulk batching — single-edge dispatch wastes the kernel's n_edges>1 amortization. Same caveat as cycles 6/7; follow-up. - QPU opportunism — see "Why" above. ## SONAME Unchanged. libavcodec.so.62 / libavformat.so.62 / libavutil.so.60. ## Refs - reauktion/daedalus-v4l2 issue #11: reauktion/daedalus-v4l2#11 - marfrit-packages PR #76 (cycle 6 IDCT 4×4) - marfrit-packages PR #85 (cycle 7 IDCT 8×8) - marfrit/daedalus-fourier cycle 8 close (deblock luma-v NEON green)	2026-05-22 12:17:14 +02:00

Extends libavcodec/aarch64/ h264_idct_daedalus.c (introduced by 0003) with ff_h264_idct8_add_daedalus and a daedalus_recipe_dispatch_h264_idct8 call; patches libavcodec/aarch64/h264dsp_init_aarch64.c to wire c->idct8_add to the new shim. - arch/PKGBUILD + debian/build-deb.sh: append the new patch to the apply list; bump pkgrel/PKGREL to 7. - No new build-deps, no Depends change, no daedalus-fourier rev — the d87239d pin already exposes daedalus_recipe_dispatch_h264_idct8. ## Why The recipe layer picks the substrate; for cycle 7 (H.264 IDCT 8×8) the recipe is CPU NEON, so this is effectively a NEON-to-NEON substitution layered on top of cycle 6. Production validation of cycle 6 on higgs Firefox YouTube: 3040 frames decoded cleanly, avg_decode_us=3388 (no regression vs the pre-substitution ~4 ms baseline). Cycle 7 inherits the same shim's pthread_once context. Bit-exact against ff_h264_idct8_add_neon (daedalus-fourier cycle 7 green; FFmpeg 8×8 block storage block[r + 8*c] matches daedalus column-major convention). ## Scope NOT covered (deferred) - Bulk c->idct8_add4 (inter 8×8-DCT macroblocks) stays on the in-tree NEON .S code; batched substitution with n_blocks>1 lands later alongside the cycle-6 bulk-paths work. - High-bit-depth (10-bit) path untouched. - Cycles 8/9 — separate PRs. ## SONAME Unchanged. libavcodec.so.62 / libavformat.so.62 / libavutil.so.60. ## Refs - reauktion/daedalus-v4l2 issue #11 (substitution arc): reauktion/daedalus-v4l2#11 - marfrit-packages PR #76 (cycle 6 IDCT 4×4) - marfrit-packages PR #78 (libxml2 ABI-skew workaround) - marfrit/daedalus-fourier cycle 7 close (H.264 IDCT 8×8 NEON green)	2026-05-22 10:20:27 +02:00
marfrit	7ecbcb3c1b	mesa-panvk-bifrost-video: regenerate 0005 patch from POST-review snapshot ... The original 0005 patch was generated from the pre-Phase-5-review source snapshot (phase5_review_input_2026-05-21.tgz), missing the four load-bearing review fixes that landed in the post-review snapshot: - probe_hantro gate on KHR_video_* extension advertisement - per-session ts_counter (was process-global static) - panvk_v4l2_session_finish full unwind (munmap + STREAMOFF + REQBUFS=0) - MIN2(rb.count, 18) clamp on num_*_buffers Run #162 (job 17032) failed in prepare() because the PKGBUILD sanity check 'grep -q "KHR_video_queue = PAN_ARCH < 9 && panvk_v4l2_probe_hantro()"' didn't match the actual patched output (which still had the pre-review 'KHR_video_queue = PAN_ARCH < 9,'). This patch (regenerated from phase5_post_review_2026-05-21.tgz) carries all four review fixes. Validated locally: vanilla mesa-26.0.6 + r1..r4 + this patch reproduces prepare()-OK byte-for-byte.
