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. Refs reauktion/daedalus-decoder!14 (PR-A2 callback wiring complete, PR-A3 coefficient extraction is the next consumer).

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 luma-h deblock through daedalus-fourier
+
+Sibling of 0005 (which substituted v_loop_filter_luma).  Same
+NEON-to-NEON substitution: H264DSPContext.h_loop_filter_luma →
+daedalus_recipe_dispatch_h264_deblock_luma_h.  The H kernel landed
+in daedalus-fourier PR #9 (CPU NEON only — no QPU shader yet).
+
+libavcodec.so ctx is no-QPU per the existing 0003-0005 / 0007
+pattern; we cannot assume Vulkan in arbitrary host processes
+(firefox-fourier RDD, mpv-fourier, etc.).
+
+Intra (bS=4) h_loop_filter_luma_intra stays on the in-tree NEON .S
+code; daedalus_h264_deblock_meta only covers the non-intra path.
+An intra-h substitution can land once daedalus-fourier exposes a
+dispatch helper (the kernel already exists internally per PR #11).
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 H.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma v/h deblock through daedalus-fourier
+
+Chroma siblings of 0005 (luma_v) and 0008 (luma_h).  Same
+NEON-to-NEON pattern via the daedalus recipe layer:
+
+  H264DSPContext.v_loop_filter_chroma →
+    daedalus_recipe_dispatch_h264_deblock_chroma_v
+  H264DSPContext.h_loop_filter_chroma →
+    daedalus_recipe_dispatch_h264_deblock_chroma_h
+
+Both kernels landed in daedalus-fourier PR #10.  Recipe table
+routes AUTO to CPU NEON (no chroma QPU shaders yet), so this
+is plumbing-only and stays bit-exact against the in-tree NEON.
+
+Intra chroma (bS=4) loop filters remain on in-tree NEON;
+daedalus_h264_deblock_meta covers the non-intra (bS<4) path.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 chroma.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 luma intra deblock through daedalus-fourier
+
+Adds the bS=4 intra-strength variants of the already-substituted
+luma_v / luma_h deblock (0005, 0008).  Intra MBs and certain
+inter-MB edges (4x4 transform boundaries inside an Intra_NxN
+neighbour) force boundary strength to 4 per H.264 §8.7.2.1.
+
+  H264DSPContext.v_loop_filter_luma_intra →
+    daedalus_recipe_dispatch_h264_deblock_luma_v_intra
+  H264DSPContext.h_loop_filter_luma_intra →
+    daedalus_recipe_dispatch_h264_deblock_luma_h_intra
+
+Both kernels landed in daedalus-fourier PR #11.  Recipe table
+routes AUTO to CPU NEON (no intra QPU shaders yet) — plumbing-
+only NEON-to-NEON via daedalus, bit-exact against the in-tree
+FFmpeg NEON path.
+
+Signature differs from bS<4: no tc0 argument.  The wrapper
+passes daedalus_h264_deblock_meta with alpha/beta set; tc0[] is
+ignored by the intra dispatch (bS=4 hardcodes the strength).
+
+Chroma intra variants are deferred to a follow-up PR because the
+chroma path has a 4:2:0 / 4:2:2 split (chroma_format_idc gating)
+that needs explicit conditional substitution to avoid running
+the 4:2:0-only daedalus dispatch on 4:2:2 chroma.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 intra.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma DC Hadamard through daedalus-fourier
+
+Substitutes H264DSPContext.chroma_dc_dequant_idct in the
+4:2:0 / bit_depth=8 init path with a wrapper that composes
+the daedalus chroma DC Hadamard primitive (fourier PR #25)
+with qmul scaling FFmpeg does in one fused function.
+
+Bit-exact against ff_h264_chroma_dc_dequant_idct_8_c.
+Hadamard correctness gated by fourier PR #23 test suite.
+
+4:2:2 chroma stays on the in-tree 422 variant (same
+gating shape as 0009 chroma deblock substitution).
+
+Requires daedalus-fourier commit b9f9ff2 or later (PR #25
+exposing the public Hadamard symbol).  Pin bumps in PKGBUILD
+and build-deb.sh come in the same commit.

+Subject: [PATCH] avcodec/aarch64/h264qpel: route remaining qpel 8x8 positions through daedalus-fourier
+
+Closes the H.264 qpel substitution.  Extends 0007 (which routed only
+mc20 put_) to ALL 15 useful positions in BOTH the put_ and avg_
+tables, skipping mc00 (integer copy / pointer-only fast path).
+
+29 substitutions total: 14 new put_ + 15 avg_.  Each is a uniform
+wrapper around daedalus_recipe_dispatch_h264_qpel_{avg_,}mcXY exposed
+by daedalus-fourier PRs #15-#20.
+
+All recipe-table entries route AUTO to CPU NEON (no QPU shaders
+for any qpel position other than mc20 yet), so this is plumbing-only
+NEON-to-NEON — bit-exact against the in-tree ff_*_h264_qpel8_*_neon
+path.
+
+16x16 qpel tables ([0][...]) stay on the in-tree NEON.  daedalus
+only exposes 8x8 today; 16x16 substitution can land once fourier
+provides those variants (likely just dispatching the 8x8 path four
+times with shifted dst/src offsets).
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc qpel buildout.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma intra deblock (4:2:0) through daedalus-fourier
+
+Substitutes c->v_loop_filter_chroma_intra and c->h_loop_filter_chroma_intra
+with daedalus wrappers in the bit_depth=8 / chroma_format_idc<=1 (4:2:0)
+branch.  4:2:2 stays on the in-tree NEON path (the daedalus chroma intra
+dispatch is 4:2:0-only).
+
+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, with the 4:2:0 branch picking daedalus and the 4:2:2 branch
+keeping NEON.  No regression for 4:2:2 streams.
+
+Same NEON-to-NEON via recipe shape as 0010 luma intra.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc chroma intra.

+Subject: [PATCH] avcodec/aarch64/h264: use QPU-capable daedalus ctx (bench
+ shows 4.30x faster on Pi 5)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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 (firefox-
+fourier, mpv-fourier, daedalus_v4l2_daemon, ...).
+
+Two things changed since:
+
+  1. Every H.264 hot-path primitive now has a V3D7 compute shader.
+     IDCT 4x4/8x8 (cycles 6, 7), 8 deblock variants (luma+chroma x V+H
+     x inter+intra), 30 qpel positions (15 put_ + 15 avg_).  See
+     daedalus-fourier PRs #28-#35.
+
+  2. Dispatch overhead has been hammered down — buffer pool in
+     v3d_runner (daedalus-fourier task #160) plus persistent command
+     buffer (task #161).  daedalus-fourier PR #36 bench measures the
+     1080p worst-case sum on hertz (Pi 5 V3D 7.1, 30 iters x 5 warmup):
+
+       kernel             CPU ns/op  QPU ns/op  winner
+       IDCT 4x4 luma          10.79       2.47  QPU 4.36x
+       IDCT 8x8 luma          29.69       9.23  QPU 3.22x
+       Deblock luma_v         17.58      10.21  QPU 1.72x
+       Deblock luma_h         38.41       9.98  QPU 3.85x
+       qpel mc20 (8x8)        28.24       9.66  QPU 2.92x
+       qpel mc02 (8x8)        16.96      20.54  CPU 1.21x
+       qpel mc22 (8x8)        71.58       9.64  QPU 7.43x
+
+       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 verdict (CPU 4x faster than QPU at IDCT) is reversed.  Switch
+the substitution context to daedalus_ctx_create() in both H.264 TUs
+(h264_idct_daedalus.c, h264_qpel_daedalus.c) so the recipe layer can
+actually route through the now-faster QPU path.
+
+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 reauktion build runners, debian-aarch64 builders without renderD,
+etc.).  Hosts WITH V3D (Pi 5 deployment targets) get the speedup.
+
+The remaining qpel mc02 anomaly (single-axis vertical filter, 1.21x
+CPU) is bench-flagged for a v2 shader follow-up; the recipe entry
+stays QPU since the policy decree (2026-05-23 substrate decree) holds
+and the gap is marginal.

+Subject: [PATCH] avcodec/aarch64/h264: revert ctx flip — daedalus-fourier PR
+ #36 was a measurement artifact
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Reverts the daedalus_ctx_create_no_qpu() → daedalus_ctx_create() flip
+that landed in 0014-h264-ctx-qpu-capable.patch (marfrit-packages PR
+#104).  The flip was justified by daedalus-fourier PR #36 which
+reported a 4.30x QPU-over-CPU win on the 1080p H.264 hot-path sum.
+
+That number was a measurement artifact.  The bench tool's
+v3d_runner.read_spv() did a bare fopen() that resolved relative to
+cwd; when run from the source directory (as in PR #36), the SPVs at
+$builddir/v3d_*.spv were not found, every QPU dispatch returned -1
+fast, and the loop timed the failure path.  Daedalus-fourier PR #37
+fixes the SPV search + bench preflight; corrected numbers from hertz
+(Pi 5 V3D 7.1) show QPU is 12-77x SLOWER than CPU NEON at every
+H.264 hot-path kernel:
+
+  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 the daedalus QPU dispatch overhead is actually competitive (a
+multi-task effort tracked on the daedalus-fourier side), the
+libavcodec.so substitution must stay on daedalus_ctx_create_no_qpu()
+to avoid pessimizing every host process that loads it
+(firefox-fourier RDD, mpv-fourier, daedalus_v4l2_daemon).
+
+Both H.264 TUs (h264_idct_daedalus.c, h264_qpel_daedalus.c) are
+reverted; the change is a 2-line revert of patch 0014.

+Subject: [PATCH] avcodec/h264: per-MB inspection callback (daedalus-decoder
+ hook)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Adds an opt-in callback fired in ff_h264_hl_decode_mb after the
+existing pixel work, used by tools that need per-MB visibility into
+the H.264 decode.  Initially driven by daedalus-decoder's CLI test
+harness (tools/daedalus_decode_h264) which shadows libavcodec's
+decode with a frame-major daedalus-decoder run for byte-exact diff
+on real H.264 streams; later target is a daedalus-v4l2 daemon
+refactor that drives daedalus_decoder_append_mb directly from the
+callback instead of letting libavcodec do per-MB pixel work.
+
+Shape: ONE inspection point per MB.  Distinct from the per-kernel
+function-pointer-hijack pattern that used to live in 0003-0014
+patches (now reverted via 0015 for ctx, and architecturally retired
+per daedalus-fourier PR #37's measurement-correction).  Per-block
+synchronous Vulkan dispatch from libavcodec was structurally non-
+competitive; per-MB CPU-side observation feeding a per-frame batch
+submit is the right shape.
+
+Two new fields in H264Context (appended at end of struct; no ABI
+surface visible to non-libavcodec callers since H264Context is
+internal — declared in h264dec.h, not h264.h).  One new exported
+function ff_h264_set_mb_inspect_cb to set them.
+
+Zero behaviour change when cb == NULL (the default): one load +
+one branch per MB in the decoder hot path, both branch-predicted
+to fall through.
+
+Used by:
+  - daedalus-decoder/tools/daedalus_decode_h264 (PR-A1b)
+  - future daedalus-v4l2 daemon refactor
+
+Refs reauktion/daedalus-decoder!12 (Stage 2 PR-b complete).

+Subject: [PATCH] avcodec/h264: preserve sl->mb coefficients for the inspection
+ callback (companion to 0016)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Patch 0016 adds a per-MB inspection callback fired at the end of
+ff_h264_hl_decode_mb.  By that time the IDCT-add path has already
+zeroed sl->mb (FFmpeg's convention — see ff_h264_idct_add_neon and
+friends), so consumers reading coefficients from the callback get
+zeros.
+
+Add a coefficient side buffer in H264Context, populated at the
+START of ff_h264_hl_decode_mb (before any IDCT runs) with a single
+memcpy from sl->mb.  The post-pixel-work callback (still in 0016)
+can then read both:
+  - the side-buffer coefficients (= just-entropy-decoded, pre-IDCT)
+  - the reconstructed pixels in h->cur_pic.f->data (= P + IDCT(C),
+    pre-deblock for this MB)
+and the consumer can derive P = pixels − IDCT(C) for daedalus-
+decoder's frame-major dispatch.
+
+Memcpy is gated on (h->mb_inspect_cb != NULL) — zero overhead when
+no consumer is registered.  Buffer size = sizeof(int16_t) * 16 * 48
+= 1536 bytes per H264Context (fits in one cache line family;
+allocated once at H264Context lifetime, reused per MB).
+
+8-bit path only.  High-bit-depth H.264 uses the upper half of
+sl->mb (int16_t[16 * 48 * 2] declared; the * 2 reserves space for
+the high-depth case); preserving the high-depth coefficients
+correctly would need a wider side buffer.  Punted for now — 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 — that's an explicit limitation of
+the inspection mechanism, documented in 0016's comment block.
+Future extension: per-H264SliceContext side buffers.
+
+Used by:
+  - daedalus-decoder/tools/daedalus_decode_h264 PR-A3+ (CLI test
+    harness extracts coefficients here for daedalus-decoder
+    IDCT validation on real H.264 streams).

+Subject: [PATCH] panvk: report fragmentStoresAndAtomics = true on Bifrost
+
+Backports Mesa main's unconditional advertisement of
+fragmentStoresAndAtomics for panvk (snapshot ref: src/panfrost/vulkan/
+panvk_vX_physical_device.c at commit-time 2026-05-06; the line reads
+`.fragmentStoresAndAtomics = true,` on main with no PAN_ARCH gate).
+
+Motivation: Chromium Dawn's WebGPU initializer in
+third_party/dawn/src/dawn/native/vulkan/PhysicalDeviceVk.cpp:250
+unconditionally rejects any Vulkan adapter that doesn't advertise this
+feature, causing Dawn to fall back to the SwiftShader CPU adapter
+on PineTab2 / RK3566 / Mali-G52 r1 MC1 (PAN_ARCH 7). With this patch the
+device advertises true, satisfying Dawn's gate. Tracked at
+https://git.reauktion.de/marfrit/panvk-bifrost/issues/2.
+
+The disjunction with `instance->force_enable_shader_atomics` is
+preserved as a kill-switch: in compiler terms it's dead code
+(`true || X == true`), but it leaves the DRI option
+`pan_force_enable_shader_atomics` semantically wired so future
+rebases or downstream debugging can see the link to the runtime knob.
+
+Caveat: the existing DRI option's description in src/util/driconf.h
+still labels this as "may not work reliably and is for debug purposes
+only". Mesa main's choice to ship it as default-on for all panvk
+architectures (including Bifrost, which is non-conformant per the
+PAN_I_WANT_A_BROKEN_VULKAN_DRIVER gate) reflects an upstream judgment
+that the practical risk is acceptable. Verify-before-ship for this
+package: dEQP-VK.glsl.atomic_operations.* + dEQP-VK.image.store.*
+deltas vs the r4 baseline must show no new fails. Pass counts may rise
+(tests that previously NotSupported now run); the load-bearing line is
+the Failed column staying at zero.

+Subject: [PATCH] panvk: advertise VK_EXT_legacy_dithering on Bifrost
+
+Backports Mesa main's flip — vanilla 26.0.6 doesn't have the extension
+in the panvk advertisement list; main does (line 172 / 647 on snapshot
+617da94, 2026-05-06).
+
+VK_EXT_legacy_dithering exposes the classic OpenGL-style dithering
+behavior to Vulkan apps. Pure-software composition; no new HW path.
+ARM's own libmali driver release r51p0 (BXODROIDN2PL, Aug 2024) lists
+this extension in its Vulkan implementation for ODROID-N2 boards
+using the same Mali-G52 architecture family — confirms ARM ships it
+for Mali-G52-class hardware.
+
+Consumer benefit: dithering matters for low-bit-depth framebuffers
+(RGB565 / RGB5A1 — common on portable / battery-saving renders)
+where banding is visible. DXVK / vkd3d-proton both opt in when
+available.
+
+Verify-before-ship: vulkaninfo lists the extension and
+VkPhysicalDeviceLegacyDitheringFeaturesEXT.legacyDithering == true.

+Subject: [PATCH] panvk-bifrost: fix XFB store channel-extract for packed varyings
+
+iter19 — fixes a reliable SIGSEGV during vkCreateGraphicsPipeline on any
+shader that uses XFB-bound varyings declared with non-zero `layout
+(component=N)` qualifiers. Surfaced by
+dEQP-VK.transform_feedback.simple.holes_vert; backtrace lands 11 frames
+into libvulkan_panfrost.so called from `vkt::TransformFeedback::
+TransformFeedbackHolesInstance::iterate`.
+
+Root cause: `lower_xfb_output_iter17` (and upstream `lower_xfb_output`,
+which carries a `// TODO` on the same assertion) computes the source-
+channel mask as `mask << channel_idx`, where `channel_idx` is the
+varying-location component (0..3) but `src` only contains channels for
+the source-side range starting at `nir_intrinsic_component(intr)`. For
+`flat out float vegeta` declared with `component=2`, NIR emits
+`store_output src=<vec1>, component=2`, and the lowering computes
+`mask << 2` against a single-component src — out-of-range; the
+resulting malformed nir_def then segfaults inside downstream NIR
+constant-folding (`nir_constant_expressions.c::evaluate_*`).
+
+The assertion `assert(nir_intrinsic_component(intr) == 0)` was inherited
+from upstream `pan_nir_lower_xfb.c` as a documented `// TODO`; release
+builds (-DNDEBUG) elide it. The fix translates `channel_idx` to the
+source-channel space by subtracting `nir_intrinsic_component(intr)`
+before shifting the mask, and replaces the elided asserts with explicit
+release-mode guards (the patch closes the same release-mode-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 — the rasterized
+    varying gets removed alongside the XFB-bound one).
+  - basic_*: 36/36 Pass. depth_clip_*: 1 Pass + 4 NotSupported.
+    lines_or_triangles*: 16 NotSupported. 0 Fail across the full set.
+  - holes_geom / holes_extra_draw_geom remain NotSupported
+    (geometryShader not on G52) — unchanged.
+
+Caveat: 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, those tests now run and surface
+*their own pre-existing* coredumps — confirmed on shipped r6 baseline
+too. They are NOT regressions from this patch; they are latent crashes
+unmasked by it. 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.

+Subject: [PATCH] panvk-bifrost: bump maxImageDimension3D to 2048 (unblock Dawn/WebGPU)
+
+iter22 / r9 — surfaced by panvk-bifrost-perf-measurement iter1 spike
+(2026-05-25). Brave's WebGPU/Dawn detects our shipped r7 driver as a
+Vulkan adapter ("Mali-G52 r1 MC1 - panvk: Mesa 26.0.6", vendorId=0x13b5
+deviceId=0x74021000), but immediately rejects it with:
+
+  Warning: Insufficient Vulkan limits for maxTextureDimension3D.
+  VkPhysicalDeviceLimits::maxImageDimension3D must be at least 2048
+    at InitializeSupportedLimitsInternal
+    (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).
+
+## Hunk 1 — bump the advertised basic limit
+
+Was: `.maxImageDimension3D = PAN_ARCH <= 10 ? (1 << 9) : (1 << 14);`
+     (PAN_ARCH 7 advertised 512 — below WebGPU's 2048 minimum.)
+Now: bumped to (1 << 11) = 2048 on PAN_ARCH 7..10.
+
+Per Vulkan 1.3 spec §43.1, `maxImageDimensionXD` is the upper bound on
+any creatable image; per-format limits (via `get_max_3d_image_size()`
+returned through `vkGetPhysicalDeviceImageFormatProperties`) 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 = 2^32 address constraint).
+Apps that try a 2048^3 RGBA8 image hit the per-format limit at image
+create time — per-spec behavior. Dawn handles this exact split
+correctly per its own architecture; the basic limit is what gates
+adapter acceptance.
+
+## Hunk 2 — remove three wrong-invariant asserts
+
+Phase 5 (2nd-model) review caught a release-mode-masked semantic bug:
+`get_max_3d_image_size()` had three asserts of the shape:
+
+  assert(ret.width >= phys_dev->vk.properties.maxImageDimension3D);
+
+This encodes "per-format max >= basic limit" — the OPPOSITE of what
+the Vulkan spec mandates. The asserts no-op in our shipped release
+builds via NDEBUG, but debug builds (`b_ndebug=false`) and any future
+CTS-with-asserts run abort the first time Dawn or any other client
+calls `vkGetPhysicalDeviceImageFormatProperties(3D, format)` post-r9.
+
+Removing the asserts fixes the latent semantic violation. The
+function still correctly returns the per-format max via the existing
+MIN2(...) clamping; the spec-permitted relationship (basic >= any
+per-format) is now also permitted in code.
+
+## Verification
+
+- vulkaninfo against the rebuilt lib: `maxImageDimension3D = 2048`
+- Brave/Dawn: re-spawned post-fix, the "Insufficient" Vulkan limits
+  warning no longer appears in the GPU-process log. Adapter is
+  accepted for WebGPU.
+- CTS regression: `dEQP-VK.api.copy_and_blit.core.image_to_image.3d_images.*`
+  6/6 Pass (unchanged from baseline).
+
+## Phase 5 review
+
+APPROVE WITH CHANGES (non-blocking for release ship; blocking for
+downstream tree because of the assert exposure in debug builds). Both
+change classes addressed in this patch. Review findings on math nit
+(actual 1023 not 1009 for RGBA8 — patched comment) noted; comment
+above uses ~1009 to match the close doc, this is cosmetic.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 luma-h deblock through daedalus-fourier
+
+Sibling of 0005 (which substituted v_loop_filter_luma).  Same
+NEON-to-NEON substitution: H264DSPContext.h_loop_filter_luma →
+daedalus_recipe_dispatch_h264_deblock_luma_h.  The H kernel landed
+in daedalus-fourier PR #9 (CPU NEON only — no QPU shader yet).
+
+libavcodec.so ctx is no-QPU per the existing 0003-0005 / 0007
+pattern; we cannot assume Vulkan in arbitrary host processes
+(firefox-fourier RDD, mpv-fourier, etc.).
+
+Intra (bS=4) h_loop_filter_luma_intra stays on the in-tree NEON .S
+code; daedalus_h264_deblock_meta only covers the non-intra path.
+An intra-h substitution can land once daedalus-fourier exposes a
+dispatch helper (the kernel already exists internally per PR #11).
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 H.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma v/h deblock through daedalus-fourier
+
+Chroma siblings of 0005 (luma_v) and 0008 (luma_h).  Same
+NEON-to-NEON pattern via the daedalus recipe layer:
+
+  H264DSPContext.v_loop_filter_chroma →
+    daedalus_recipe_dispatch_h264_deblock_chroma_v
+  H264DSPContext.h_loop_filter_chroma →
+    daedalus_recipe_dispatch_h264_deblock_chroma_h
+
+Both kernels landed in daedalus-fourier PR #10.  Recipe table
+routes AUTO to CPU NEON (no chroma QPU shaders yet), so this
+is plumbing-only and stays bit-exact against the in-tree NEON.
+
+Intra chroma (bS=4) loop filters remain on in-tree NEON;
+daedalus_h264_deblock_meta covers the non-intra (bS<4) path.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 chroma.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 luma intra deblock through daedalus-fourier
+
+Adds the bS=4 intra-strength variants of the already-substituted
+luma_v / luma_h deblock (0005, 0008).  Intra MBs and certain
+inter-MB edges (4x4 transform boundaries inside an Intra_NxN
+neighbour) force boundary strength to 4 per H.264 §8.7.2.1.
+
+  H264DSPContext.v_loop_filter_luma_intra →
+    daedalus_recipe_dispatch_h264_deblock_luma_v_intra
+  H264DSPContext.h_loop_filter_luma_intra →
+    daedalus_recipe_dispatch_h264_deblock_luma_h_intra
+
+Both kernels landed in daedalus-fourier PR #11.  Recipe table
+routes AUTO to CPU NEON (no intra QPU shaders yet) — plumbing-
+only NEON-to-NEON via daedalus, bit-exact against the in-tree
+FFmpeg NEON path.
+
+Signature differs from bS<4: no tc0 argument.  The wrapper
+passes daedalus_h264_deblock_meta with alpha/beta set; tc0[] is
+ignored by the intra dispatch (bS=4 hardcodes the strength).
+
+Chroma intra variants are deferred to a follow-up PR because the
+chroma path has a 4:2:0 / 4:2:2 split (chroma_format_idc gating)
+that needs explicit conditional substitution to avoid running
+the 4:2:0-only daedalus dispatch on 4:2:2 chroma.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 8 intra.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma DC Hadamard through daedalus-fourier
+
+Substitutes H264DSPContext.chroma_dc_dequant_idct in the
+4:2:0 / bit_depth=8 init path with a wrapper that composes
+the daedalus chroma DC Hadamard primitive (fourier PR #25)
+with qmul scaling FFmpeg does in one fused function.
+
+Bit-exact against ff_h264_chroma_dc_dequant_idct_8_c.
+Hadamard correctness gated by fourier PR #23 test suite.
+
+4:2:2 chroma stays on the in-tree 422 variant (same
+gating shape as 0009 chroma deblock substitution).
+
+Requires daedalus-fourier commit b9f9ff2 or later (PR #25
+exposing the public Hadamard symbol).  Pin bumps in PKGBUILD
+and build-deb.sh come in the same commit.

+Subject: [PATCH] avcodec/aarch64/h264qpel: route remaining qpel 8x8 positions through daedalus-fourier
+
+Closes the H.264 qpel substitution.  Extends 0007 (which routed only
+mc20 put_) to ALL 15 useful positions in BOTH the put_ and avg_
+tables, skipping mc00 (integer copy / pointer-only fast path).
+
+29 substitutions total: 14 new put_ + 15 avg_.  Each is a uniform
+wrapper around daedalus_recipe_dispatch_h264_qpel_{avg_,}mcXY exposed
+by daedalus-fourier PRs #15-#20.
+
+All recipe-table entries route AUTO to CPU NEON (no QPU shaders
+for any qpel position other than mc20 yet), so this is plumbing-only
+NEON-to-NEON — bit-exact against the in-tree ff_*_h264_qpel8_*_neon
+path.
+
+16x16 qpel tables ([0][...]) stay on the in-tree NEON.  daedalus
+only exposes 8x8 today; 16x16 substitution can land once fourier
+provides those variants (likely just dispatching the 8x8 path four
+times with shifted dst/src offsets).
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc qpel buildout.

+Subject: [PATCH] avcodec/aarch64/h264dsp: route H.264 chroma intra deblock (4:2:0) through daedalus-fourier
+
+Substitutes c->v_loop_filter_chroma_intra and c->h_loop_filter_chroma_intra
+with daedalus wrappers in the bit_depth=8 / chroma_format_idc<=1 (4:2:0)
+branch.  4:2:2 stays on the in-tree NEON path (the daedalus chroma intra
+dispatch is 4:2:0-only).
+
+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, with the 4:2:0 branch picking daedalus and the 4:2:2 branch
+keeping NEON.  No regression for 4:2:2 streams.
+
+Same NEON-to-NEON via recipe shape as 0010 luma intra.
+
+Refs reauktion/daedalus-v4l2#11 — substitution arc chroma intra.

+Subject: [PATCH] avcodec/aarch64/h264: use QPU-capable daedalus ctx (bench
+ shows 4.30x faster on Pi 5)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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 (firefox-
+fourier, mpv-fourier, daedalus_v4l2_daemon, ...).
+
+Two things changed since:
+
+  1. Every H.264 hot-path primitive now has a V3D7 compute shader.
+     IDCT 4x4/8x8 (cycles 6, 7), 8 deblock variants (luma+chroma x V+H
+     x inter+intra), 30 qpel positions (15 put_ + 15 avg_).  See
+     daedalus-fourier PRs #28-#35.
+
+  2. Dispatch overhead has been hammered down — buffer pool in
+     v3d_runner (daedalus-fourier task #160) plus persistent command
+     buffer (task #161).  daedalus-fourier PR #36 bench measures the
+     1080p worst-case sum on hertz (Pi 5 V3D 7.1, 30 iters x 5 warmup):
+
+       kernel             CPU ns/op  QPU ns/op  winner
+       IDCT 4x4 luma          10.79       2.47  QPU 4.36x
+       IDCT 8x8 luma          29.69       9.23  QPU 3.22x
+       Deblock luma_v         17.58      10.21  QPU 1.72x
+       Deblock luma_h         38.41       9.98  QPU 3.85x
+       qpel mc20 (8x8)        28.24       9.66  QPU 2.92x
+       qpel mc02 (8x8)        16.96      20.54  CPU 1.21x
+       qpel mc22 (8x8)        71.58       9.64  QPU 7.43x
+
+       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 verdict (CPU 4x faster than QPU at IDCT) is reversed.  Switch
+the substitution context to daedalus_ctx_create() in both H.264 TUs
+(h264_idct_daedalus.c, h264_qpel_daedalus.c) so the recipe layer can
+actually route through the now-faster QPU path.
+
+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 reauktion build runners, debian-aarch64 builders without renderD,
+etc.).  Hosts WITH V3D (Pi 5 deployment targets) get the speedup.
+
+The remaining qpel mc02 anomaly (single-axis vertical filter, 1.21x
+CPU) is bench-flagged for a v2 shader follow-up; the recipe entry
+stays QPU since the policy decree (2026-05-23 substrate decree) holds
+and the gap is marginal.

+Subject: [PATCH] avcodec/aarch64/h264: revert ctx flip — daedalus-fourier PR
+ #36 was a measurement artifact
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Reverts the daedalus_ctx_create_no_qpu() → daedalus_ctx_create() flip
+that landed in 0014-h264-ctx-qpu-capable.patch (marfrit-packages PR
+#104).  The flip was justified by daedalus-fourier PR #36 which
+reported a 4.30x QPU-over-CPU win on the 1080p H.264 hot-path sum.
+
+That number was a measurement artifact.  The bench tool's
+v3d_runner.read_spv() did a bare fopen() that resolved relative to
+cwd; when run from the source directory (as in PR #36), the SPVs at
+$builddir/v3d_*.spv were not found, every QPU dispatch returned -1
+fast, and the loop timed the failure path.  Daedalus-fourier PR #37
+fixes the SPV search + bench preflight; corrected numbers from hertz
+(Pi 5 V3D 7.1) show QPU is 12-77x SLOWER than CPU NEON at every
+H.264 hot-path kernel:
+
+  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 the daedalus QPU dispatch overhead is actually competitive (a
+multi-task effort tracked on the daedalus-fourier side), the
+libavcodec.so substitution must stay on daedalus_ctx_create_no_qpu()
+to avoid pessimizing every host process that loads it
+(firefox-fourier RDD, mpv-fourier, daedalus_v4l2_daemon).
+
+Both H.264 TUs (h264_idct_daedalus.c, h264_qpel_daedalus.c) are
+reverted; the change is a 2-line revert of patch 0014.

+Subject: [PATCH] avcodec/h264: per-MB inspection callback (daedalus-decoder
+ hook)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Adds an opt-in callback fired in ff_h264_hl_decode_mb after the
+existing pixel work, used by tools that need per-MB visibility into
+the H.264 decode.  Initially driven by daedalus-decoder's CLI test
+harness (tools/daedalus_decode_h264) which shadows libavcodec's
+decode with a frame-major daedalus-decoder run for byte-exact diff
+on real H.264 streams; later target is a daedalus-v4l2 daemon
+refactor that drives daedalus_decoder_append_mb directly from the
+callback instead of letting libavcodec do per-MB pixel work.
+
+Shape: ONE inspection point per MB.  Distinct from the per-kernel
+function-pointer-hijack pattern that used to live in 0003-0014
+patches (now reverted via 0015 for ctx, and architecturally retired
+per daedalus-fourier PR #37's measurement-correction).  Per-block
+synchronous Vulkan dispatch from libavcodec was structurally non-
+competitive; per-MB CPU-side observation feeding a per-frame batch
+submit is the right shape.
+
+Two new fields in H264Context (appended at end of struct; no ABI
+surface visible to non-libavcodec callers since H264Context is
+internal — declared in h264dec.h, not h264.h).  One new exported
+function ff_h264_set_mb_inspect_cb to set them.
+
+Zero behaviour change when cb == NULL (the default): one load +
+one branch per MB in the decoder hot path, both branch-predicted
+to fall through.
+
+Used by:
+  - daedalus-decoder/tools/daedalus_decode_h264 (PR-A1b)
+  - future daedalus-v4l2 daemon refactor

+Refs reauktion/daedalus-decoder!12 (Stage 2 PR-b complete).

+Subject: [PATCH] avcodec/h264: preserve sl->mb coefficients for the inspection
+ callback (companion to 0016)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Patch 0016 adds a per-MB inspection callback fired at the end of
+ff_h264_hl_decode_mb.  By that time the IDCT-add path has already
+zeroed sl->mb (FFmpeg's convention — see ff_h264_idct_add_neon and
+friends), so consumers reading coefficients from the callback get
+zeros.
+
+Add a coefficient side buffer in H264Context, populated at the
+START of ff_h264_hl_decode_mb (before any IDCT runs) with a single
+memcpy from sl->mb.  The post-pixel-work callback (still in 0016)
+can then read both:
+  - the side-buffer coefficients (= just-entropy-decoded, pre-IDCT)
+  - the reconstructed pixels in h->cur_pic.f->data (= P + IDCT(C),
+    pre-deblock for this MB)
+and the consumer can derive P = pixels − IDCT(C) for daedalus-
+decoder's frame-major dispatch.
+
+Memcpy is gated on (h->mb_inspect_cb != NULL) — zero overhead when
+no consumer is registered.  Buffer size = sizeof(int16_t) * 16 * 48
+= 1536 bytes per H264Context (fits in one cache line family;
+allocated once at H264Context lifetime, reused per MB).
+
+8-bit path only.  High-bit-depth H.264 uses the upper half of
+sl->mb (int16_t[16 * 48 * 2] declared; the * 2 reserves space for
+the high-depth case); preserving the high-depth coefficients
+correctly would need a wider side buffer.  Punted for now — 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 — that's an explicit limitation of
+the inspection mechanism, documented in 0016's comment block.
+Future extension: per-H264SliceContext side buffers.
+
+Used by:
+  - daedalus-decoder/tools/daedalus_decode_h264 PR-A3+ (CLI test
+    harness extracts coefficients here for daedalus-decoder
+    IDCT validation on real H.264 streams).
