libva-v4l2-request-fourier: bump pin to c454618 (#15 transparent resize)

Bumps both Arch PKGBUILD and Debian build-deb.sh pins to PR #16 —
codec_store_buffer + request_pool_resize transparent OUTPUT-pool grow
on a mid-session resolution upshift overrun.  Picks up the frame-
survival path that supersedes #13's drop-and-recreate fallback.

Dual-pin per feedback_marfrit_packages_dual_pin so both Arch and
Debian repos see check-already-published.sh report a new version.

+# check-already-published.sh <recipe-dir>
+#
+# Decide whether a given recipe (arch/<name> or debian/<name>) is already
+# present in https://packages.reauktion.de/.  Emits exactly one line to
+# stdout:
+#
+#   skip=1   — package with this version-pkgrel-arch tuple already lives in
+#              the pool; CI should short-circuit.
+#   skip=0   — file is missing or HEAD failed; CI should build + publish.
+#
+# Design notes:
+#   * For Arch recipes we source the PKGBUILD in a clean subshell so
+#     shell expansions (epoch=, ${_pkgver/-/}, pkgname=() arrays) resolve
+#     naturally.  Only the first element of pkgname[] is checked — split
+#     packages share one source tarball / one build, so any-one-missing
+#     forces the full rebuild anyway.
+#   * For Debian recipes we extract the bare top-level PKGVER= /
+#     PKGREL= assignments (plus any other top-level VAR=value lines they
+#     reference) via grep and re-evaluate them in an isolated subshell —
+#     sourcing the entire build-deb.sh would run curl/tar/dpkg-deb
+#     against a tempdir we don't want to materialise here.
+#   * Epoch handling differs by ecosystem: Arch keeps `<epoch>:` in the
+#     pool filename, Debian/reprepro strips it.
+#   * curl --head with -f maps non-2xx to non-zero exit, which is what we
+#     want — 404 means "build it".  -L follows mirrors.  --max-time caps
+#     the worst-case latency per HEAD.

+
+Without this, Mesa's Zink driver refuses to use PanVk-Bifrost as its Vulkan
+backend, falling back silently to llvmpipe (software rasterizer) for all
+GL-via-Zink on Bifrost SBCs. That defeats the entire purpose of having a
+Vulkan driver on Bifrost — GL acceleration via Zink is the most natural
+near-term consumer.
+
+panvk_vX_nir_lower_descriptors.c:1309 and panvk_vX_shader.c:1355 already
+plumb dev->vk.enabled_features.nullDescriptor arch-agnostically — the gate
+at panvk_vX_physical_device.c was set conservatively when Bifrost was
+unmaintained, not because of hardware incapability.
+
+iter1–7 of the panvk-bifrost campaign proved fundamental driver functions
+on Mali-G52 r1 MC1 (PAN_ARCH=7). This patch is the iter8 follow-up.
+
+robustBufferAccess2 and robustImageAccess2 are NOT flipped — they're
+independent rb2 features Zink doesn't require, gated differently
+(robustBufferAccess2 = PAN_ARCH >= 11, robustImageAccess2 = false), and
+out of scope for iter8.

+Subject: panvk: expose Vulkan 1.1 + 1.2 on Bifrost (PAN_ARCH 6/7)
+
+ANGLE (Chromium's GL stack) requires apiVersion >= 1.1 to initialize. Without

+
+  vk_renderer.cpp:2659 (initialize): ANGLE Requires a minimum Vulkan device

+
+Stack-up with iter8's robustness2 patch enables ANGLE → PanVk-Bifrost →
+Skia (via --enable-features=Vulkan) on Bifrost SBCs.
+
+PanVk-Bifrost already supports the bulk of 1.1-promoted features as extensions
+(multiview, maintenance1-3, descriptor update template, 16-bit storage,
+descriptor update template, sampler ycbcr, variable pointers, etc. — all
+visible in iter0 vulkaninfo). The version bump primarily bundles them.
+
+Risk: Vulkan 1.1 has features beyond what iter1–7 exercised (protected memory,
+full subgroup ops). Specific app failures will be characterizable.
+
+1.2 is also flipped — Brave's Vulkan path may want descriptor indexing,
+buffer device address, etc. (all listed in iter0 vulkaninfo as supported
+extensions, just gated as 1.0-with-extensions, not 1.2-core).

+# mesa-panvk-bifrost — patched Mesa libvulkan_panfrost.so that exposes
+# Bifrost-gen Mali (Mali-G31/G52/G72/G76, PAN_ARCH 6/7) to Chromium-family
+# browsers' Vulkan compositor.
+#
+# Campaign: ~/src/panvk-bifrost/ — iter9 close (technical milestone
+# 2026-05-20, operator-confirmed Brave window). Goal close requires
+# this package built + published + installable per the
+# feedback_package_done_means_installable.md 3-point check.
+#
+# What it does:
+#   - Builds Mesa 26.0.6 (matching ohm's stock mesa pkg) with two
+#     patches against src/panfrost/vulkan/panvk_vX_physical_device.c:
+#     (1) expose VK_KHR/EXT_robustness2 + nullDescriptor on PAN_ARCH 6/7
+#     (2) set has_vk1_1/has_vk1_2 to true on Bifrost
+#   - Installs the patched libvulkan_panfrost.so to /usr/lib/panvk-bifrost/
+#     (NOT /usr/lib — co-installs alongside stock mesa).
+#   - Registers a custom ICD JSON at a non-default path so the system
+#     Vulkan loader only picks up our driver when VK_ICD_FILENAMES is set.
+#   - Ships /usr/bin/brave-vulkan launcher that wires up env vars + flags.
+#
+# Co-existence: stock /usr/lib/libvulkan_panfrost.so is untouched. Stock
+# /usr/share/vulkan/icd.d/panfrost_icd.json is untouched. Users opt in
+# via brave-vulkan (or by setting VK_ICD_FILENAMES manually).
+#
+# Build target: arch-aarch64 runner via marfrit-packages Gitea Actions.
+# Mesa build is slow (~30-60min on Cortex-A55). Build deps installed
+# inside the runner via pacman -S in the workflow.

+# mesa-panvk-bifrost
+
+Patched Mesa `libvulkan_panfrost.so` exposing Bifrost-gen Mali GPUs
+(Mali-G31/G52/G72/G76, PAN_ARCH 6/7) to Chromium-family browsers'
+Vulkan compositor.
+
+Result of the **panvk-bifrost** campaign ([`~/src/panvk-bifrost/`](../../../panvk-bifrost/)),
+iter9 close 2026-05-20 (technical milestone — operator-confirmed Brave
+window) followed by this package as the actual delivery.
+
+## What it solves
+
+Stock Chromium / Brave on Bifrost SBCs (PineTab2, etc.) currently dies
+at GL bindings init:
+
+```
+ERROR: ui/gl/gl_context_egl.cc:120  GLES3 is unsupported and ES version fallback is disabled
+ERROR: ui/gl/init/gl_factory.cc:111  Requested GL implementation not found
+ERROR: components/viz/service/main/viz_main_impl.cc:189  Exiting GPU process due to errors during initialization
+```
+
+This package makes Brave's **Vulkan compositor path** work on Bifrost,
+side-stepping the failing GL stack. Browser chrome and standard page
+rendering work.
+
+## Known limitations (not addressed)
+
+- **WebGL / WebGL2** in-page: blocked. ANGLE needs `VK_EXT_transform_feedback`
+  to expose GLES3 contexts; PanVk-Bifrost doesn't currently support that.
+  Sites using WebGL will degrade or refuse.
+- **VAAPI hardware video decode**: unrelated to this package — see the
+  `libva-v4l2-request-fourier` package for that path.
+
+## Install
+
+```sh
+# Ensure [marfrit] is in /etc/pacman.conf, then:
+sudo pacman -Sy mesa-panvk-bifrost
+```
+
+## Use
+
+```sh
+brave-vulkan                                    # launches Brave with Vulkan
+brave-vulkan https://www.example.com
+brave-vulkan --your-flags-here                  # extra args passed through
+```
+
+The launcher sets:
+
+- `VK_ICD_FILENAMES=/usr/lib/panvk-bifrost/icd.json` (the patched driver)
+- `PAN_I_WANT_A_BROKEN_VULKAN_DRIVER=1` (Mesa upstream gate)
+- `MESA_VK_VERSION_OVERRIDE=1.2` (apiVersion bump for ANGLE)
+- Brave flags: `--use-gl=disabled --enable-features=Vulkan --use-vulkan=native --ozone-platform=x11 --no-sandbox --disable-gpu-sandbox --ignore-gpu-blocklist`
+
+## What's in the package
+
+- `/usr/lib/panvk-bifrost/libvulkan_panfrost.so` — patched Mesa Vulkan driver (Mesa 26.0.6 + 2 sed-applied patches)
+- `/usr/lib/panvk-bifrost/icd.json` — Vulkan ICD JSON pointing at the patched .so (NOT auto-loaded; only via `VK_ICD_FILENAMES`)
+- `/usr/bin/brave-vulkan` — launcher script
+
+System Mesa is untouched. The stock `/usr/lib/libvulkan_panfrost.so` and
+`/usr/share/vulkan/icd.d/panfrost_icd.json` continue to work for any
+other Vulkan app.
+
+## Co-existence
+
+Both stock Mesa and this package can be installed. Stock Vulkan apps
+(`vulkaninfo`, `vkcube`, etc.) use the stock driver by default. Only
+apps started via `brave-vulkan` (or with `VK_ICD_FILENAMES` manually
+set to our path) use the patched driver.
+
+## Campaign close criterion
+
+Per [`feedback_package_done_means_installable`](file:///home/mfritsche/.claude/projects/-home-mfritsche-src/memory/feedback_package_done_means_installable.md)
+three-point check:
+
+1. PR merged to `marfrit-packages`
+2. CI green AND `packages.reauktion.de/arch/aarch64/mesa-panvk-bifrost-*.pkg.tar.zst` exists
+3. `pacman -Ss mesa-panvk-bifrost` on a fresh consumer host (e.g. ohm
+   after `pacman -Syu` from clean state) returns the package + brave-vulkan launches
+
+When all three pass, panvk-bifrost iter9 closes.

+  * Bump to 79256dc — H.264 B-frame display reorder fix (closes
+    daedalus-v4l2#6).  libavcodec's H.264 decoder reorders output to
+    display order before returning from avcodec_receive_frame; the
+    daemon was binding each REQ_DECODE's pixels to the cookie of the
+    bitstream that triggered the receive_frame call, not the cookie
+    of the bitstream that actually produced the picture.  For B-frame
+    sequences this paired cookie N's CAPTURE buffer with cookie N-2's
+    pixels and silently lost intermediate frames — visible as
+    "2 1 4 3 6 5" frame pairing in mpv / Firefox on Pi CM5.
+  * Wire-protocol bump (DAEDALUS_PROTO_VERSION 0 → 1): REQ_DECODE
+    gains __u64 src_pts; RESP_FRAME gains __u32 flags +
+    __u64 output_src_pts.  Kernel + daemon must install atomically
+    (this package + daedalus-v4l2 0.1.0+r28+g79256dc).

+    back to software with no obvious diagnostic.  Now we enumerate every
+    /lib/modules/*/build that resolves to a real directory and run
+    `dkms autoinstall -k <kver>` for each, reporting per-kernel failure
+    only when headers are missing.  Closes #64.

+
+  * Bump to 79256dc — H.264 B-frame display reorder fix (closes
+    daedalus-v4l2#6 + #4 menu controls).  Daemon side: the
+    avcodec_send_packet → receive_frame loop now stamps pkt->pts =
+    req->src_pts so libavcodec's display-ordered frame->pts identifies
+    which OUTPUT bitstream's pixels each drained frame belongs to.
+    chardev_client maintains a (src_pts → cookie) lookup table so the
+    daemon can ship pixels to the cookie of the *originating*
+    bitstream, not the cookie of whatever REQ triggered the
+    receive_frame call.  Multiple RESP_FRAME messages per REQ_DECODE
+    are now possible (one for the just-consumed src, one or more for
+    drained pixels).
+  * Wire-protocol bump (DAEDALUS_PROTO_VERSION 0 → 1): REQ_DECODE
+    gains __u64 src_pts; RESP_FRAME gains __u32 flags +
+    __u64 output_src_pts.  Daemon + kernel must install atomically
+    (this package + daedalus-v4l2-dkms 0.1.0+r28+g79256dc).
+  * Also subsumes 79256dc's predecessor 7ff2d89 — H.264 DECODE_MODE +
+    START_CODE menu-control registration that retires the
+    "Unable to set control(s) error_idx=2/2" warning libva-v4l2-

+daedalus-v4l2 (0.1.0+r24+gf0d4186-1) bookworm trixie; urgency=medium
+
+  * Bump to f0d4186 — kernel per-ctx vb2 lock fix.  daedalus_queue_init
+    was wiring src_vq->lock and dst_vq->lock to ctx->dev->m2m_lock (a
+    device-wide mutex), serialising every vb2 ioctl across all
+    concurrent clients of /dev/video0.  For Firefox (which spawns
+    separate content + RDD + GPU processes that each open the device
+    and run libva probe simultaneously), one libva session's
+    S_FMT(OUTPUT_MPLANE) hit EBUSY while another was mid-streamon —
+    Firefox VAAPI playback fell apart at startup.
+  * Fix gives each open() its own ctx->vb_mutex; vb2 ioctls run
+    independently per client.  Matches cedrus / rkvdec / hantro
+    pattern.
+  * Verified on higgs: Firefox YouTube playback engages VAAPI cleanly,
+    sustained ~230 fps decode at 640x368 through the daedalus daemon,
+    zero EBUSY in stderr or daemon journal.

+
+  * Bump to 462aa4b — kernel-side fix for control-binding gap that
+    closes the libva→daemon SPS/PPS pipeline.  Kernel device_run now
+    calls v4l2_ctrl_request_setup() before reading ctrl->p_cur, so
+    the daemon's daedalus_h264_meta block actually carries THIS
+    request's V4L2 stateless H.264 control values instead of stale
+    /default ones.  Pairs with libva-v4l2-request-fourier r382+gc1bb444
+    (Fix 3 + Fix 4 from issue libva-v4l2-request-fourier#8).
+  * After-fix on higgs (Pi CM5): ffmpeg -hwaccel vaapi -i h264.mp4
+    produces unique decoded P-frames (per-frame fnv1a hashes differ)
+    and zero "error while decoding MB" / "reference frames exceeds
+    max" warnings.

+  * Bump to 3dd0eb0 — DAEMON-PPS H.264 SPS/PPS NAL synthesiser.
+    Daemon now reconstructs AnnexB SPS+PPS NAL units from the V4L2
+    stateless H.264 control structs (forwarded by the kernel via
+    a new struct daedalus_h264_meta block in REQ_DECODE) and
+    prepends them to the slice bitstream before feeding libavcodec.
+    Without this, ffmpeg -hwaccel vaapi on H.264 sources failed
+    with "non-existing PPS 0 referenced" even after LIBVA-1/-2
+    routing correctly delivered the request.
+  * Wire protocol: new DAEDALUS_REQ_FLAG_H264_META bit + struct
+    daedalus_h264_meta; daemon and kernel must be installed in
+    lockstep (this package + daedalus-v4l2-dkms 0.1.0+r20+g3dd0eb0).

+libva-v4l2-request-fourier (1.0.0+r380+g9898331-1) bookworm trixie; urgency=medium
+
+  * Bump to 9898331 — LIBVA-2 close.  Adds video_fd_daedalus to
+    any_fd_supports_output_format's probe list in config.c so the
+    profile enumerator actually sees daedalus_v4l2's OUTPUT formats
+    (VP9F + AV1F + S264).  Before this commit, ffmpeg vaapi against
+    H.264 on higgs bailed with "No support for codec h264 profile 578"
+    because RequestQueryConfigProfiles only walked rkvdec/hantro/
+    rpi-hevc-dec/vpu981 fds and never asked daedalus what it could do.
+  * Backward-compatible on RK3399/3588 — new slot gated by
+    HAVE_DAEDALUS_V4L2 *and* video_fd_daedalus >= 0; both false in
+    those deployments.

+libva-v4l2-request-fourier (1.0.0+r378+gc332d34-2) bookworm trixie; urgency=medium
+
+  * Rebuild on a native Debian trixie runner (actrunner-debian-aarch64-bohr) so
+    the driver picks up trixie's libva-dev (2.22) and exports
+    __vaDriverInit_1_22 — the symbol trixie's libva runtime looks up.
+    Previous -1 build used the Arch CI runner (libva 2.23.0) and
+    exported __vaDriverInit_1_23, which trixie's loader cannot bind:
+    vaInitialize() returns -1 ("has no function __vaDriverInit_1_0")
+    and ffmpeg -hwaccel vaapi fails on startup.
+  * No source change; pure build-env fix.  CI workflow's
+    libva-v4l2-request-fourier-debian job moved from runs-on:
+    arch-aarch64 to runs-on: actrunner-debian-aarch64-bohr; build-deps installed
+    via apt-get instead of pacman.
+  * Hard sanity check kept in build-deb.sh: build fails if the
+    resulting .so doesn't export __vaDriverInit_1_22 (preempts the
+    silent install-then-refuse-to-load failure mode).

+
+  * Bump to c332d34 — LIBVA-1 per-codec dispatch close.  Pi 5 mixed
+    deployment (rpi-hevc-dec + daedalus_v4l2 both loaded) now correctly
+    opens BOTH decoders: VP9/AV1/H.264 route to daedalus via new 'd'
+    kind, HEVC stays on 'p' (rpi-hevc-dec).  Before this commit
+    find_codec_device picked rpi-hevc-dec as the sole primary and the
+    daedalus_v4l2 slot stayed -1, so VP9/AV1/H.264 frames failed.
+  * Also closes a small fd leak in RequestTerminate (daedalus pair).
+  * Backward-compatible: new branches gated by HAVE_DAEDALUS_V4L2
+    *and* video_fd_daedalus >= 0 — RK3399/RK3588 boxes unaffected.
