ci: skip jobs when package already published

Wire .gitea/scripts/check-already-published.sh into every job in
build.yml. New step `skip if already published` (id: skip-check) lands
right after actions/checkout@v4 and runs the helper against the job's
recipe-dir. Subsequent steps gain `if: steps.skip-check.outputs.skip
!= '1'`, except `wipe secrets` which keeps its existing
`if: always()`.

Recipe-dir per job is taken from each job's existing `cp -r arch/...`
or `cd debian/...` line — no guessing.

Effect: on push where only e.g. firefox-fourier changed, 13 jobs HEAD
the pool, see 200, and short-circuit; only firefox-fourier rebuilds.
Verified live against packages.reauktion.de — current branch tip
would skip 10/14 jobs.

Patch is text-based (no PyYAML round-trip) so comments and blank
lines stay where they were. Diff is 190 lines added, 0 removed.

+# 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.

+From: claude-noether (on behalf of mfritsche)
+Date: 2026-05-19
+Subject: panvk: expose VK_KHR/EXT_robustness2 + nullDescriptor on Bifrost (PAN_ARCH 6/7)
+
+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
+this, Brave / Chromium's GPU process fails at GL info collection:
+
+  vk_renderer.cpp:2659 (initialize): ANGLE Requires a minimum Vulkan device
+                                     version of 1.1
+  Display::initialize error 0: Internal Vulkan error (-9): The requested
+                               version of Vulkan is not supported by the driver
+
+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

+#
+# Campaign: ~/src/panvk-bifrost/ — iter9 close (technical milestone

+#
+# 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).

+# 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.

+    drop-in (packaging/systemd/daedalus-v4l2.{service,modules-load}).
+  * Package now ships /lib/systemd/system/daedalus-v4l2.service and
+    /usr/lib/modules-load.d/daedalus-v4l2.conf.
+  * postinst: daemon-reload, enable the service, trigger
+    systemd-modules-load, and start if /dev/daedalus-v4l2 is already
+    present.  Operator no longer needs to remember the modprobe +
+    systemctl-enable dance after install.
+  * prerm/postrm: stop + disable + daemon-reload.

+
+  * Bump to f0cd29a alongside daedalus-v4l2-dkms.  No userspace
+    change — the daemon binary in this release is bit-identical to
+    the f55b2cd one (the f0cd29a commit only touches kernel/).  Bump
+    keeps the userspace + DKMS pkgver lockstep so depmod /
+    LIBVA_DRIVER_NAME selection stays correct on hosts that
+    upgrade.
