Subject: [PATCH 02/53] honeykrisp: accept a NULL array of transform feedback
 counter buffers

vkCmdBeginTransformFeedbackEXT and vkCmdEndTransformFeedbackEXT take
pCounterBuffers as NULL or as an array of handles. With NULL, Begin starts
every transform feedback buffer at byte offset zero. End writes nothing.
The conformance test passes NULL with a count of 1 for this case. The driver
read the first element of the NULL array and crashed.

Skip the loop over the counter buffers when the array is NULL. Begin still
zeroes the four offsets, and End still copies nothing. A call with an array,
and an array with a null handle in it, behave as before.

(cherry picked from commit b87e7456cdbb7abdea2f360cdcba0e2a56316f3f)

Subject: [PATCH 03/53] zink: prepare reviewed public protections over exact DJ
 524

Assemble only the ordered-access and early depth-unbind protections whose code/data dependencies remain distinct from the renderpass store guard. Preserve DJ source and the original public source copyright notices.

Ordered-access algorithm provenance: Mike Blumenkrantz, upstream b448ad053f2ce190a5b6b2d27b30dcbf3d45ec7d, public PR8 6ff2d4aa9da581e3c5f9fdaa4b51416b116d5ace (matching stable patch ID). Depth-unbind algorithm provenance: Eryk Wieliczko, public PR7 53a363032ed040c87e4ff1d97876bfd00c7e2424. Regression fixture provenance: Ryan Murray, fd3072f69db7d9e09305175c2f4f247b837bac7b.

This independently authored integration checkpoint retains their exact reviewed source changes rather than claiming new authorship of those algorithms. Original contributor commits are retained unchanged on the evidence branch and in the source bundle; the delivered topic is linear for root review, without merging any public branch.

Subject: [PATCH 04/53] zink: check current-batch ordered reads before
 unordered fast path

An index read followed by a transfer read can restore unordered_read
while unordered_write remains true. Recorded ordered reads in the same
batch must prevent a destination write from entering reordered_cmdbuf.

Retain the public PR8 history tracking and combined barrier masks, PR7
depth protections, lifecycle resets and latest DJ storeOp guard unchanged.
Reviewer1802 actual-source sequence supplies the regression control.

Subject: [PATCH 06/53] Retain independent mappings while applying
 placed-memory review checks

Adapt the range, result-address, shared-backend and cache-lifetime checks from Joshua Warren commits f91b6f40b3c6c529fc523c3339060e0af165762f and ddfb4cf114a6e72b690581ff6fb2fe8447d11ffa. Preserve the newer independent mapping implementation instead of replacing it with an older BO-wide mapping.

+# SiliconForest Mesa
+
+Personally maintained Mesa integration for Apple Silicon, by
+[iconidentify](https://github.com/iconidentify). Default branch:
+**`siliconforest/next`**, Mesa **26.3.0-devel**.
+
+This combines DJ's Neo/G17P work, Eryk Wieliczko's current M3 Pro native
+OpenGL/Vulkan work, Naeem's M3 Max additions, and selected correctness fixes.
+Original commits, author identities, copyrights and licenses are retained.
+The upstream Mesa README is [README.rst](README.rst).
+
+## Source profiles
+
+| Hardware / contract | Branch | Status in this integration |

+| Earlier M3 Max experiments | `experimental/m3-max-legacy` | Historical source profile; use the combined native branch for new development |
+
+A chip name or shader encoder alone does not establish support. Main deliberately
+refuses M3 Air/Ultra, M4 and M5 identities that lack its complete native path.
+Compatibility and experimental profiles are separate source trees, not additional
+drivers silently enabled in one binary. They have **not** undergone the main
+branch's build/test run.
+
+## Kernel and firmware pairing
+
+Native M3 Pro/Max and Neo require the ABI represented by
+`include/drm-uapi/asahi_drm.h`. In
+[SiliconForest Linux](https://github.com/iconidentify/siliconforest-linux), the
+matched header is `include/uapi/drm/asahi_m3_drm.h` in the experimental
+`CONFIG_SILICONFOREST_M3` stack, imported at
+`6a421d4e76ff282b414138182fd28597ebf20a18`.
+That kernel option remains off by default. Matching firmware and m1n1 handoffs
+must also be qualified on the target board; the current personal m1n1 pin alone
+is not proof of those handoffs.
+
+The maintained legacy kernel has different feature bit assignments and command
+payload layouts despite using the same ioctl family. Main now rejects its known
+incompatible native contract before VM creation. Do not substitute headers or
+force a chip identity to bypass that check. This is a check for the **known**
+legacy/native collision, not a universal ABI negotiation protocol.
+
+## Build and check
+
+A source build does not install files, replace system Mesa, enable a kernel
+option, or reboot anything. The integration was configured on x86_64 with
+LLVM/Clang 22.1.8, a matching SPIR-V LLVM translator, Meson 1.10.2, Mako, PLY,
+PyYAML, libdrm, SPIR-V Tools, and the development dependencies for X11/Wayland,
+EGL, GBM and Vulkan. See [validation](SILICONFOREST-VALIDATION.md) for the exact
+configuration and outcomes.
+
+Quick checks require a C compiler and Python 3. They compile and run production
+chip admission, compression, plane-layout and scratch-layout tests:
+
+```sh
+python3 tools/siliconforest/check.py
+# In a full clone with all source tags:
+python3 tools/siliconforest/check.py --check-git
+```
+
+With the build dependencies available:
+
+```sh
+python3 -m venv ../mesa-venv
+../mesa-venv/bin/pip install 'meson==1.10.2' 'Mako==1.3.10' 'ply==3.11' PyYAML pytest
+MESON="$PWD/../mesa-venv/bin/meson" JOBS=8 tools/siliconforest/build.sh ../mesa-build
+```
+
+The script builds Asahi and Zink OpenGL, Honeykrisp Vulkan, tree-matched shader
+compiler tools and drm-shim, then runs the Asahi host suite. Do not reuse shader
+compiler binaries from an older Mesa tree. There are no binary releases or
+system-install commands for this integration yet.
+
+## What was reviewed and retained
+
+[The review ledger](SILICONFOREST-REVIEW.md) explains merged changes, duplicate
+fixes, ABI findings, held regressions and experimental branches.
+[SILICONFOREST-SOURCES.json](SILICONFOREST-SOURCES.json) pins 209 public branch,
+PR and MR snapshots under `sources/2026-10-18/*`, with 37 GitHub PR records and
+25 open upstream Asahi MR records. A snapshot is evidence, not approval to ship
+its contents. This is a dated public-source investigation; it cannot establish
+that no private, deleted, unindexed or newer work exists.
+
+GitHub Actions runs the quick CPU checks on main and pull requests. Full host
+compilation and hardware qualification are distinct checks. The existing
+archived `iconidentify/aurora-linux` repository remains untouched.

+# Mesa source integration review — 2026-10-18
+
+## Main integration
+
+The starting point is the current 26.3 development tree, rather than an older
+26.1 source tree with every later branch applied over it.
+
+| Work | Exact source | Decision |
+| --- | --- | --- |
+| DJ Neo / AGX3b | `aurora-silicon/mesa:agx3b`, `dba15302aa0554b52ec6ca5103bd0391035e0fdc` | Preserved as ancestry of the native M3 source; includes DJ's merged PR12–22 work |
+| Eryk M3 Pro | [PR23](https://github.com/aurora-silicon/mesa/pull/23), `cf8ec613be202d8bfc5440e61e9aa6c60700fad7` | Main foundation; 39 commits after DJ's pinned head |
+| Naeem M3 Max | [PR25](https://github.com/aurora-silicon/mesa/pull/25), `aab698d2ef34e2aef38ba4d2bfcfa3abc5ded4c5` | Merged as original ancestry; four unique commits, preserving all nine later Eryk commits missing from this fork |
+| Joshua null transform-feedback counters | [omacom PR10](https://github.com/omacom/mesa/pull/10), `b87e7456cdbb7abdea2f360cdcba0e2a56316f3f` | Cherry-picked with provenance; no dereference of a NULL counter array |
+| Eryk/Mike/Ryan Zink protections | [PR7](https://github.com/aurora-silicon/mesa/pull/7), `53a09d65633f1e6d6cc26bf851c16f63fcec2060`, `02c37f31ded86dd39e721dfccc8b43668aecb3fb` | Imported ordered-access history, combined barrier masks, depth-unbind transition, regression fixture and fast-path follow-up |
+| Joshua placed-memory review | [omacom PR8](https://github.com/omacom/mesa/pull/8), `72c18d4deb9440c839ad2fb35b0537fd993915e0`, `f91b6f40b3c6c529fc523c3339060e0af165762f`, `ddfb4cf114a6e72b690581ff6fb2fe8447d11ffa` | Adapted missing range/result/cache checks while retaining the base's newer independent mappings for aliased imports |
+
+The Zink integration preserves the source checkpoint's attribution to Mike
+Blumenkrantz (`b448ad053f2ce190a5b6b2d27b30dcbf3d45ec7d` /
+`6ff2d4aa9da581e3c5f9fdaa4b51416b116d5ace`) and Eryk
+(`53a363032ed040c87e4ff1d97876bfd00c7e2424`). The full discovery snapshot retains
+public PR history alongside the new integration commits.
+
+## Adversarial findings and treatment
+
+1. **A newer branch name was not a superset.** Naeem's branch diverged before
+   nine Eryk correctness fixes: staging-bank/read hazards, cube texture indices,
+   half-source square root, GL scratch word packing, multisampled window
+   buffers, compute variant reuse, border-depth comparison and tile-load masks.
+   Merging into Eryk's current head retained these instead of replacing the tree
+   with Naeem's snapshot.
+2. **Known kernel ABI collision.** The maintained kernel and the experimental
+   native kernel assign different meanings to bits 3–8 and 10–15. Render and
+   compute payloads also differ by timestamp-copy fields. A GPU identity check
+   alone is insufficient. Main requires the native per-command-sync and exact
+   prior-barrier contract and rejects the known legacy high-bit assignments on
+   native AGX3 before VM creation. CPU tests exercise missing and conflicting
+   feature bits. This does not prove compatibility with arbitrary kernels that
+   fabricate the same feature word.
+3. **Blind cherry-picking regressed newer implementations.** Thomas Glanzmann's
+   [plane-offset fix](https://github.com/aurora-silicon/mesa/pull/10),
+   `ba289e643e0b361747988280a459b73c34c2cad9`, is already covered by the base's
+   `offset_B` handling plus overflow, row-pitch, overlap and binding validation.
+   Its older implementation was not reapplied. The production image-layout
+   tests are included in quick checks and the complete Asahi suite.
+4. **Placed mappings needed a selective port.** The base already tracks mapped
+   lengths and gives imported memory objects independent mappings. Replacing
+   that with PR8 would remove working alias isolation. The adaptation instead
+   adds runtime allocation/BO bounds, a runtime result-address check, protection
+   against moving a shared mapping on backends without independent mappings,
+   and release of a placed mapping before returning its BO to the cache.
+   A NULL/already-unmapped object does no reserve mmap. Physical Vulkan CTS and
+   virtio execution remain unqualified.
+5. **Capture/replay changes are not interchangeable.** Joshua's
+   [omacom PR9](https://github.com/omacom/mesa/pull/9),
+   `11ae82d8d8c379c2ae895806b4409537c5ceb25b`, introduces a separate 4-GiB range.
+   The native base already has a separate replay heap reserved after firmware
+   and alias holes. Replacing the allocator with PR9 would discard those holes.
+   Its AGX2-specific extension/error classification still needs a dedicated port
+   and is held; this repository does not claim that M1/M2 capture/replay issue is
+   resolved by the native implementation.
+6. **The reported compression failure was not reproduced.** The current exact
+   compression-policy source passes 3,035 host checks. No policy was weakened
+   and no test disabled to turn an older reported 33/34 result green.
+7. **Feature exposure stays narrow.** G15C does not gain unsupported ray-query
+   advertisement. Neo sparse aliasing/strict residency restrictions remain.
+   No broad hardware-admission switch, known-bad barrier simplification, or
+   forced compiler generation was added.
+
+## Experimental and held work
+
+| Source | Treatment and reason |
+| --- | --- |
+| Newer private M5 HAL300 research | Kept local at the owner's instruction. No private-source snapshot or runnable M5 claim is published here. |
+| DJ public `m5-agx-g15-g17-failclosed`, `068c165a0c83cab4e4c6e9a3c89f63f7a4fa0c2c` | Preserved on `experimental/m5-recognition` and as an exact source tag. Recognition/encoder research remains fail-closed, not an active M5 driver. |
+| Eryk M4, `08b19ec3a2e422a7252fdfe77c185450fccf86da` | Preserved on `experimental/m4` with original qualification evidence; no new hardware claim. |
+| Personal Air/legacy/older Pro/Max sources | Separate named profiles; firmware and kernel contracts differ from main. Only policy/branch notices are changed at their new tips. |
+| Joshua omacom PR3–6 | Source snapshots retained. Latest PR6 `f144c7949b7d960f26677b671341d5a123057ddf` reports 55 regressions over 3,253,584 cases. A narrow later pass does not qualify the complete performance stack. Not merged. |
+| Joshua PR11 `44841202b4fd041fc29b6ff77f585d4df6e70dd7` | Depends on the above performance stack; retained for review, not applied standalone or enabled. |
+| Official MR44475 phi shuffling, `e22cd9bd50daa4671b41a81ee72c8238a0604a8f` | Examined. Main has the newer parallel-phi implementation that snapshots original destinations and whole vector ranges. The older one-line reverse-walk fix is not a drop-in replacement. |
+| Official MR44041 lighter CDM barriers | Retained for review. It removes undocumented barrier bits and does not establish equivalent cache guarantees for the merged native GPU paths. |
+| Official MR44931 geometry heap option, MR44932 virtio implicit-sync optimization | Exact candidate heads retained. Current heap initialization and external-BO lifetime code differ; do not blindly apply older callbacks or sync assumptions. |
+| Official GL/Vulkan interop MR42872, memory-budget MR40238, SVM MR37668 | Candidate snapshots retained; these are separate features requiring targeted runtime validation, not prerequisites for native M3/Neo source integration. |
+| Official Mesa main, `c823a83e8f373a5c36c2b9ed1d7dc98a4f3360ee` | Pinned as a future rebase source. It is 1,335 commits beyond this fork's October 1 base and includes cross-driver/NIR interface changes. Not merged wholesale during this chip-stack integration. |
+| Official Asahi fork main, `01ac84e119f468a3267714b0b4a339316a3083f4` | Checked directly; its tip is dated April 2025, so it is not presumed newer than the current Mesa development source. |
+| DJ Windows D3DKMT/WC/UMD branches | Preserved in the inventory; not mixed into Linux default behavior. |
+
+## Review limits
+
+This is a provenance/graph/dependency review, focused inspection of integration
+boundaries and correctness fixes, host compilation and CPU tests. DJ's base alone
+changes hundreds of files and includes generated tables and captured fixtures;
+this is not a claim that every inherited line has been independently audited.
+No M3/Neo/M4/M5 hardware, physical GPU execution, compositor session, firmware
+recovery, full Vulkan/OpenGL CTS or game compatibility was tested here. Source
+preservation is not a substitute for those checks.

Subject: [PATCH 11/53] Update the stale compute wire-size assertion for the
 ray-intersection tail

The production payload is 136 bytes, matching the experimental kernel header. Keep the 64/72/80-byte SCS and prior-barrier offsets asserted and add 88/128-byte assertions for the appended state.

Subject: [PATCH 12/53] Sequence RT fixture lengths and preserve placed
 addresses in drm-shim

The RT test read len in the same argument list as the encoder changed it, which is unsequenced in C and failed under GCC. Read the length through a pointer inside the expectation after encoding; preserve all 611 checks and pinned bytes. Forward mmap addresses through drm-shim so MAP_FIXED tests exercise the requested address rather than trying to map address zero. Include Meson test dependencies when selecting host build targets.

+   wire assertion still described an older 88-byte packet; it now checks the
+   actual 136-byte payload and the appended field offsets. The RT fixture read
+   a length in the same C argument list that an encoder modified it; reading
+   through a pointer inside the assertion sequences those operations without
+   changing expected bytes. All 611 checks remain. The generic drm-shim mmap
+   wrapper dropped the requested address, making placed mappings try address
+   zero; it now forwards that address. All 36 Asahi suites and the four host
+   Vulkan regression profiles pass, including Vulkan validation on the latter.

+# SiliconForest Mesa validation — 2026-10-18
+
+Validated source: **`3cca5b305cda31558540dbba86f0074568a4cb27`**.
+The following documentation/evidence commit does not change driver source.
+Machine-readable results and exact driver subtree IDs are in
+[SILICONFOREST-VALIDATION.json](SILICONFOREST-VALIDATION.json).
+
+| Check | Result |
+| --- | --- |
+| Asahi/Zink shared Gallium driver, Honeykrisp shared Vulkan driver, GLX/EGL/GBM | Built successfully on x86_64 Linux |
+| Tree-matched shader compiler tools and Asahi drm-shim | Built successfully |
+| Complete registered Asahi host suite | **36 passed, 0 failed** |
+| Quick production CPU test programs | **4 passed**, including **3,035** compression-policy checks |
+| Public provenance / compatibility profile validation | **209** exact tags and **6** public source profiles checked |
+| Native experimental kernel wire ABI | **18** selected ioctl/layout/feature facts matched |
+| Maintained legacy kernel negative control | Rejected with **10** differing facts |
+| Host Vulkan device/pipeline/mapping/XFB probes | **4 passed**: G13G, G15S, G15C and G17P drm-shim identities |
+| Same Vulkan probes with Khronos validation enabled | **4 passed**, **0 validation errors**, **0 GPU submissions** |
+| Build helper shell syntax / ShellCheck, Python syntax, Git whitespace | Passed |
+
+The host Vulkan probe primes the BO cache with an oversized allocation, maps a
+smaller allocation at a reserved address, checks the following guard page,
+reserves/remaps it, and frees it while mapped. It also records NULL counter
+arrays inside rendering with a bound XFB-capable pipeline and feedback buffer.
+It creates and compiles a graphics pipeline but never submits a command buffer.
+The embedded shader header is generated from the adjacent GLSL source.
+
+The build used GCC 16.2.1, LLVM/Clang 22.1.8, Meson 1.10.2, Mako 1.3.10 and
+PLY 3.11. Shader compiler dependencies were provided from a private build prefix,
+without installing Mesa or changing system packages. Configuration:
+
+```sh
+meson setup BUILD SOURCE \
+  -Dgallium-drivers=asahi,zink,softpipe -Dvulkan-drivers=asahi \
+  -Dplatforms=x11,wayland -Dglx=dri -Degl=enabled -Dgbm=enabled \
+  -Dglvnd=disabled -Dllvm=enabled -Dbuild-tests=true \
+  -Dtools=asahi,drm-shim -Dmesa-clc=enabled -Dprecomp-compiler=enabled \
+  -Dvideo-codecs= -Dgallium-va=disabled
+python3 tools/siliconforest/build-targets.py BUILD
+meson test -C BUILD --no-rebuild --suite asahi --print-errorlogs
+python3 tools/siliconforest/check.py --check-git
+python3 tools/siliconforest/check-kernel-abi.py PATH_TO_SILICONFOREST_LINUX
+VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation \
+  python3 tools/siliconforest/drm-smoke.py BUILD
+```
+
+`build-targets.py` includes all registered Asahi test dependencies, including
+executables launched through the Python drm-shim wrapper. It does not build or
+run unrelated Mesa-wide tests. The shader compiler tools are built from this
+source tree, rather than reused from an older Mesa build.
+
+The stale 88-byte compute assertion was corrected against the actual 136-byte
+kernel payload, retaining explicit field-offset checks. The ray-traversal
+fixture now reads output lengths after encoding, eliminating an unsequenced C
+read/write; all **611** checks and their expected instruction bytes are retained.
+The generic drm-shim mmap wrapper now forwards the requested address, enabling
+real `MAP_FIXED` mapping coverage instead of accidentally requesting address zero.
+
+No physical Apple GPU, full OpenGL/Vulkan CTS, compositor, games, firmware
+recovery, AArch64 deployment or virtio execution was qualified. The six other
+source profiles were preserved, not built or tested by this run. No system Mesa
+installation, kernel-option change, m1n1 replacement or reboot was performed.
+Private-source work remains local as instructed.

+# Maintaining SiliconForest Mesa
+
+The default integration is `siliconforest/next`. Keep original contributor
+commits and licensing intact; use merges or `git cherry-pick -x` with a written
+record of any conflict resolution. Label newly generated commits as described
+in `AGENTS.md`.
+
+## Reviewing a source update
+
+1. Check the source repository's visibility before including its refs or code in
+   a publication. For GitHub, use `gh api repos/OWNER/REPO --jq .visibility`.
+   Private-source work stays in local research refs and notes. This public
+   integration contains public-source code only.
+2. Pin the exact source SHA, compare divergence against the current integration,
+   and review dependencies and duplicate implementations. A newer topic name is
+   not proof that it includes another branch's fixes.
+3. Keep identity, topology, USC, HAL and kernel-ABI admission checks intact.
+   Hardware recognition and shader encoding alone do not establish support.
+4. Update `SILICONFOREST-SOURCES.json` and the review ledger. Source tags preserve
+   evidence; their existence does not mean every experiment is approved for the
+   default build.
+
+## Checking the integration
+
+Run the quick checks, build the affected drivers and all registered Asahi test
+dependencies, and run the host suite. For changes around device setup, mappings
+or synchronization, also run the Vulkan drm-shim regression probe with Khronos
+validation enabled. Commands and the exact baseline results are in
+`SILICONFOREST-VALIDATION.md`.
+
+`check.py --check-git` works with local maintainer branches or the corresponding
+`origin/*` refs in a fresh full clone. It verifies exact source tags and the
+limited changes to compatibility profiles. The quick GitHub workflow runs
+without requiring all historical source tags or a complete Mesa build.
+
+## Publishing source
+
+Push explicit branch/tag refs from the reviewed source manifest. Do not use an
+unrestricted `--mirror`, `--all` or `--tags` push from a research checkout that
+also holds private or unreviewed refs. For a new repository, keep it private until
+its remote ref set and source access checks match the intended public inventory.
+Cancelling a local wrapper process is not proof that its upload children stopped.
+
+Keep experimental firmware/driver profiles separate. Before publishing installable
+packages, qualify the exact board, firmware, m1n1 handoffs and kernel ABI on
+hardware, run the relevant CTS and compositor/application checks, and record the
+results against a pinned source. Host CPU tests and drm-shim checks do not replace
+that hardware qualification. Source maintenance must not install Mesa or alter a
+working boot stack as a side effect.

Subject: [PATCH 24/53] Copy external-memory extension payload before
 compression admission

GCC 16.1.1 on AArch64 at -O3 miscompiled a format-list chain followed by external-memory image creation. Copy the typed payload as well as the chain header, keeping external/shared images uncompressed.

Validation: existing policy suite, 3035 checks each, passes GCC -O0/-O2/-O3 on AArch64 16.1.1 and x86_64 16.2.1. No GPU or firmware qualification is claimed.

Subject: [PATCH 25/53] asahi: clamp a comparing sampler's border depth for
 fixed-point formats only

The comparison clamps the border depth to [0, 1] for a fixed-point depth
format and uses it unclamped for a floating-point one. Commit
"asahi: clamp the border depth of a comparing sampler" clamped it for
Z32F too. That is against the spec and no longer changes any result:
the border_clamp depth_compare_mode iterations it targeted pass without
it on J514S.

Keep the clamp for fixed-point depth only. Z24 is still clamped by
fixup_border_zs() before its promotion to Z32F.

Subject: [PATCH 26/53] hk: make the checked geometry heap size configurable

Adapt official Mesa MR44931 into the current device-owned initialization
callback. Keep allocation/map failure handling, one-time initialization and
shader-stage warm-up intact. The default stays 128 MiB; applications can
select 16..1024 MiB with hk_geometry_heap_size_mb. No game override or new
hardware/performance qualification is implied by this source change.

+`a2a5472089a029c067a2e3e35adc420643603065`, is adapted in `86e11a3ee2d` with
+s0ullight's author credit. The option is `hk_geometry_heap_size_mb`, default
+128 MiB, valid range 16–1024 MiB. The implementation keeps the current device
+callback, one-time initialization, shader-stage warm-up and BO/map failure
+handling. No allocator or native kernel ABI guard is replaced.
+
+The upstream change adds no per-game profile. An explicit setting such as
+`hk_geometry_heap_size_mb=256 your-game` is needed to opt in; this integration
+does not establish that a game crash is fixed or that general FPS improves.
+The production callback is exercised under ASan/UBSan by the public CPU checker,
+including the default, both limits, the 256 MiB override and BO/map failures.
+A fresh x86_64 build from this public source tree passed all 36 registered Asahi
+tests. The generated option parser rejected invalid/out-of-range settings in
+11 direct parser checks. These are host checks, without GPU qualification.

Subject: [PATCH 29/53] Bound XML geometry heap overrides before u32 GPU
 publication

Adversarial review found that XML drirc values bypass descriptor range validation. Clamp the configured size to 16..1024 MiB before BO allocation and assert that the maximum fits the GPU u32 heap/range fields. Keep existing warm-up and OOM behavior.

Use the actual poly_heap declaration in the CPU regression and exercise 12 in-range and malformed-range integer settings under ASan/UBSan. The generated XML parser plus real callback also passed 12 settings including 0, -1, 4096 and 5000.

Subject: [PATCH 31/53] asahi/clc: build the internal programs for G15G

G15G (T8122, M3) shares the agx3b encoding with G15S but needs explicit
scheduling stalls (agx_chip_needs_scheduling_stalls), so the G15S build
of the precompiled programs is not usable on it. Add a g15g target.
Nothing selects it yet.

Subject: [PATCH 32/53] asahi: keep G15G allocations out of the T8122 runtime
 reservations

The T8122 kernel runtime reserves four ranges in every VM: its USC base
at 0x1000000000, the top half of the 2^40 USC window, 0x1074000000 and
0x7000000000 up to 0x8000000000. Binds that touch them fail with EINVAL.
The native AGX3 layout puts the internal programs at the top of the
window, the sparse alias of the heap across 0x7000000000, and compact
VDM aliases at 0x1000800000.

On G15G, use the lower half of the window, cap the heap and its sparse
alias below 0x7000000000 (agx_va_user_limit: heap [0x4000000000,
0x5000000000), alias up to 0x6000000000, below the 2^39 bound of the
absolute USC Texture/Sampler field), and keep the compact alias heap out
of the runtime USC base. The 0x1074000000 range already falls inside the
alias heap's reserved span. The constants mirror the kernel's
Runtime::new_vm by hand. Nothing admits G15G yet.

Subject: [PATCH 33/53] asahi: admit G15G on the native path behind
 ASAHI_M3_EXPERIMENTAL

Run the M3 (T8122, G15G) on the native AGX3 path with the G15S profile
(G15 records, Gen4 samplers, classic queues), with its own build of the
internal programs and its scheduling stalls, against the kernel's T8122
runtime on the 14.8.3 firmware. G15G is admitted only for chip 0x8122,
one die and one cluster, AGX3 and the legacy firmware interface, and the
device opens it only with ASAHI_M3_EXPERIMENTAL=1, the switch mesa-m3
already uses (with mesa-m3's warning line), through
agx_chip_experimental_admitted(). Without it the driver says so instead
of reporting an unknown command stream. The chip admission test covers
G15G's identity, the gate (unset, 0 and 1) and the G15G heap layout
against the runtime's reservations and the 2^39 bound.

On a J613 (MacBook Air 13-inch, M3) with the T8122 runtime, an earlier
version of this series, with the heap above the USC window, passed
compute-check and a GLES draw with readback through zink on honeykrisp
and on the Gallium driver. This layout has not run on hardware yet.

Subject: [PATCH 34/53] Keep Air opt-in exact and standalone CPU admission
 checks buildable

Require the documented ASAHI_M3_EXPERIMENTAL=1 spelling, keeping the pure chip module independent of the configured Mesa debug utility. Check unset, empty, 0, true and 1. Enable POSIX environment declarations in the standalone C test build.

Subject: [PATCH 35/53] Admit the Air runtime actual feature contract without
 requiring G15 prior barriers

The pinned Aurora kernel m3/m3_drm.rs Backend::feature_flags reports VM_STATUS and SCHEDULED_QUEUES for T8122, with optional compute/fragment capabilities. Require that baseline for G15G, preserving exact chip/firmware identity and explicit experimental opt-in. Other native profiles still require the unified PER_COMMAND_INPUT_SYNCS and EXACT_PRIOR_BARRIERS bits. Cover missing baseline bits and optional capabilities in the production admission test.

Subject: [PATCH 36/53] Exercise experimental Air device setup and refusal
 paths with drm-shim

Add a synthetic G15G identity using the pinned T8122 runtime feature baseline and reject binds into its four reserved VA ranges. Extend the existing no-submit Vulkan device/pipeline/mapping probe to opt-in G15G and explicit refusal for unset/0 Air opt-in and unqualified M4. These host probes do not model firmware execution or prove hardware support.

Subject: [PATCH 37/53] Align host fixtures with opt-in Air barriers and held
 M4 device admission

Scott PR71 grounds the G15G wide barrier; move that chip into the positive pack/unpack cases and retain negative coverage on other chips. Keep upstream M4 compiler capability predicates available for offline tests, but refuse T8132 and T6040 at the actual device-parameter admission gate until separate qualification.

Subject: [PATCH 38/53] Record pinned October 24 integration and preserve
 diagnostic results from refusal probes

Retain 209 historical public snapshots and compatibility refs, add the two exact Aurora/Scott source tags, and document unified kernel pairing, Air runtime admission, unresolved hardware qualification and preserved downstream fixes. Restore instruction-file symlink modes. Accept the Vulkan loader no-device initialization result only in explicit refusal probes, and print captured diagnostics before failing a probe.

+refuses M3 Ultra, M4 and M5 admission. Native M3 Air is experimental and
+requires its exact identity, a compatible kernel and the explicit opt-in above.
 Compatibility and experimental profiles are separate source trees, not additional
 drivers silently enabled in one binary. They have **not** undergone the main
 branch's build/test run.
 
 ## Kernel and firmware pairing
 
-Native M3 Pro/Max and Neo require the ABI represented by
-`include/drm-uapi/asahi_drm.h`. In
-[SiliconForest Linux](https://github.com/iconidentify/siliconforest-linux), the
-matched header is `include/uapi/drm/asahi_m3_drm.h` in the experimental
-`CONFIG_SILICONFOREST_M3` stack, imported at
-`6a421d4e76ff282b414138182fd28597ebf20a18`.
-That kernel option remains off by default. Matching firmware and m1n1 handoffs
-must also be qualified on the target board; the current personal m1n1 pin alone
-is not proof of those handoffs.
-
-The maintained legacy kernel has different feature bit assignments and command
-payload layouts despite using the same ioctl family. Main now rejects its known
-incompatible native contract before VM creation. Do not substitute headers or
-force a chip identity to bypass that check. This is a check for the **known**
-legacy/native collision, not a universal ABI negotiation protocol.
+Native M3 Pro/Max, experimental M3 Air and Neo use the unified Aurora ABI
+represented by `include/drm-uapi/asahi_drm.h`. The checked kernel source is
+[omacom/linux-aurora at 7b969982](https://github.com/omacom/linux-aurora/tree/7b969982306e1498a8cbe6e5da9bde743acd8fc5),
+`include/uapi/drm/asahi_drm.h`. The update uses the high feature-bit assignments
+and timestamp-copy command fields from that contract. It rejects the older
+low-bit native contract before VM creation; this is a check for the known
+collision, not universal ABI negotiation. The older SiliconForest experimental
+header checked on October 18 is no longer the matching contract.
+
+Do not substitute headers, force a chip identity or use an old kernel simply
+because its version string resembles the checked one. Kernel configuration,
+firmware and m1n1 handoffs still need qualification on the actual board.
+M3 Air retains `ASAHI_M3_EXPERIMENTAL=1`; its kernel startup configuration is
+separate. This source update does not change any installed boot stack.

+
+The update merges Aurora `aurora-wip` at
+`4911479bf988ce88ec0889ed0378352a0bb0fae2` and Scott Jones's draft
+[PR71](https://github.com/aurora-silicon/mesa/pull/71) at
+`0163e7fa96f4c54f2fb72e6053b2aaa22446a44d`. Both remain original ancestry,
+with original author identities. There were 214 upstream-only commits and 33
+downstream-only commits before integration; these counts include merges and
+maintenance, not 214 missing M3 driver fixes.
+
+- Retain downstream placed-mapping ownership, fixed-address drm-shim behavior,
+  the checked configurable geometry heap, and Zink ordering fixes. Equivalent
+  upstream RT fixture sequencing and NULL XFB counter handling replace the old
+  implementations without dropping their regression coverage.
+- Update the known-collision ABI gate for Aurora's unified high feature bits
+  and timestamp-copy payloads. The checked 18 wire facts match kernel
+  `7b969982306e1498a8cbe6e5da9bde743acd8fc5`. The prior low-bit native
+  header is incompatible, so this is not an automatic system upgrade.
+- T8122's separate runtime reports VM_STATUS and SCHEDULED_QUEUES, without
+  exact-prior barriers (`m3/m3_drm.rs:217` in the pinned kernel). Give G15G its
+  own baseline check instead of requiring the Pro/Max/Neo feature pair. Host
+  drm-shim probes cover its actual feature baseline and reject user binds into
+  all four T8122 reservations; no GPU submission is performed.
+- Keep M4 admission disabled even though the upstream snapshot contains M4
+  code. Preserve T6030/T6031/Neo identity checks. T8122 additionally requires
+  the literal `ASAHI_M3_EXPERIMENTAL=1`; empty, `0`, `true`, and unset refuse.
+- Keep all four T8122 runtime reservations and the below-2^39 heap/alias cap.
+  The updated layout has host tests, but Scott's earlier hardware results used
+  a different layout. J613 texture/MSAA/compute and desktop checks remain due;
+  J615 and HAL200 are not qualified by those earlier results.
+- GCC 16 at `-O2` exposed a nested pNext compression rejection regression.
+  Copying each header's type and next pointer through untyped storage, plus
+  copying the external-memory payload, preserves all 3,359 policy checks;
+  neither the policy nor the failing assertion is relaxed.
+- Preserve this fork's assistant policy; do not import Aurora's workflow that
+  rewrites it. Historical compatibility branches and private-source exclusions
+  are unchanged.
+
+The later Aurora code includes native render-pass/depth-store improvements,
+query-progress and upload-reuse work, compiler fixes, and the unified kernel
+UAPI. No FPS gain is claimed without a matched hardware benchmark. Full CTS,
+M1/M2/M3 hardware regression tests and installing a system package remain
+separate from host compilation and drm-shim validation.

Subject: [PATCH 39/53] Check image-write type semantics without requiring
 identical chip schedules

The G17P/G16G image-store regression compared whole compiler binaries even though their legal register copies and schedules differ. Preserve all ten type/format cases on both chips, require exactly one image-write packet, compare that packet across chips, and independently check its float-versus-integer field. The deliberate production mutation encoding float writes as integers compiled and was killed by the updated assertion; original compiler source was restored.

   Copying each header's type and next pointer through untyped storage, plus

+- Host fixtures now follow the integrated policies: G15G wide CDM barriers

   rewrites it. Historical compatibility branches and private-source exclusions
   are unchanged.

Subject: [PATCH 40/53] Record passing October 24 Mesa build and host
 regression evidence

91 Asahi suites, five Vulkan no-submit device/mapping profiles, three refusal controls, five CPU programs, 211 source tags, kernel ABI match/mismatch controls and three deliberate mutations. Record exact tested source/subtrees and outstanding hardware, AArch64, CTS and performance qualification; preserve the October 18 evidence.

+# SiliconForest Mesa validation
+
+## October 24 integration candidate
+
+Tested source: **`c66c1969387bada0f1ace561d4c424822b803251`**.
+Later validation-only documentation does not change the tested driver subtrees.
+
+| Check | Result |
+| --- | --- |
+| Asahi/Zink OpenGL, Honeykrisp Vulkan, GLX/EGL/GBM, matched shader tools | Built on x86_64 with GCC 16.2.1, LLVM 22.1.8 and Meson 1.10.2 |
+| Complete registered Asahi host suite | **91 passed, 0 failed**; existing optional FMA oracle subtest remains skipped |
+| Standalone CPU programs and provenance | **5 passed**, 3,359 compression checks, 211 exact public tags and six preserved compatibility refs |
+| Vulkan device/pipeline/placed-map/XFB probes | **5 passed**: G13G, G15S, G15C, G17P and opt-in G15G |
+| Vulkan refusal controls | **3 passed**: G15G without opt-in, G15G opt-in=0, and held G16G with Air opt-in=1 |
+| Khronos validation | **0 errors**, **0 GPU submissions** across those eight probes |
+| Unified Aurora kernel contract | **18 wire facts match** `7b969982306e1498a8cbe6e5da9bde743acd8fc5`; old SiliconForest native header rejected with ten differences |
+| Deliberate negative mutations | Air gate bypass, removed Air address cap and float-as-integer image writes all compile and are caught |
+| Syntax and Git whitespace | Passed |
+
+The build uses the configuration below with `--buildtype=debugoptimized` and
+`-Db_ndebug=false`. It uses private shader-tool dependencies and performs no
+system installation. Build warnings are retained in the log; this is not a
+warning-free build claim.
+
+The G15G drm-shim identity is synthetic. Its baseline features match the Air
+runtime's VM_STATUS/SCHEDULED_QUEUES contract; it refuses binds into the four
+reserved ranges. It exercises host allocation and pipeline setup without
+executing a shader. The revised Air layout, physical M1/M2/M3 regressions,
+AArch64 package, full CTS, desktop stability and any FPS change remain untested.
+No kernel, firmware, m1n1, system package or boot setting was changed.
+
+The host run exposed stale expectations for G15G wide barriers and held M4
+admission, plus a compiler fixture comparing unrelated chip schedules. The
+corrected compiler fixture retains all type/format cases, compares the single
+image-write packet, and checks its data-type bit independently; a deliberate
+wrong-type compiler mutation fails it. No production compiler change was made.
+
+Exact tree IDs, pinned sources, evidence hashes and the earlier baseline are in
+[SILICONFOREST-VALIDATION.json](SILICONFOREST-VALIDATION.json).

Subject: [PATCH 42/53] Enable supported T8122 Air GPUs by default without a
 Mesa environment opt-in

Remove the extra ASAHI_M3_EXPERIMENTAL device-open gate at the owner request. Keep exact T8122 topology, legacy firmware, runtime feature and VA reservation checks. Exercise the real device-open path with the obsolete variable unset, 0 and 1, and retain M4 refusal with it set. This does not change kernel Kconfig, boot flags or package pins; hardware qualification of the revised Air layout remains pending.

Subject: [PATCH 43/53] Record default M3 Air admission and refreshed host
 validation

G15G no longer needs an environment opt-in; retain exact supported identity, firmware/runtime feature checks and reservations. Record the complete repeated host suites and default-device probes, with the prior validation preserved.

Subject: [PATCH 44/53] Translate the retained Omacom G15 wire at the DRM
 boundary

The integration boot reports the Mesa-751 G15 feature and packet contract even on the current Omacom kernel. Select its exact admitted G15S/G15C signatures, normalize features and translate hardware packets while rejecting nonzero timestamp-copy slots. Preserve the canonical paths for other devices and virtio.

Validation: 92 Asahi host tests pass, including retained-wire positive and refusal controls. Seven positive and one refusal drm-shim cases pass without GPU submissions. Physical follow-up pending.

+# Omacom retained G15 wire compatibility
+
+The J516S boot at kernel `7.2.11-lab7b969982-2e59`, built from
+`omacom/linux-aurora@7b969982306e1498a8cbe6e5da9bde743acd8fc5`, reported
+GET_PARAMS features `0x3e`, USC 3 and HAL 0. The initial integration refused it
+before VM creation. No GPU benchmark was run on that failed admission.
+
+The source explains the distinction:
+
+- [g15/wire.rs](https://github.com/omacom/linux-aurora/blob/7b969982306e1498a8cbe6e5da9bde743acd8fc5/drivers/gpu/drm/asahi/g15/wire.rs)
+  explicitly retains the Mesa-751 private wire. Feature words are `0x3e`, or
+  `0xbe` with early tiling. Render is 384 bytes with priors at 256/264; compute
+  is 136 bytes with scratch at 64 and priors at 72/80.
+- The canonical header contains eight additional timestamp-copy records in
+  each payload. Canonical render is 448 bytes with priors at 320/328; compute
+  is 200 bytes with scratch at 128 and priors at 136/144. Its per-command sync,
+  mirror and exact-prior feature assignments also differ.
+- [g15/command.rs](https://github.com/omacom/linux-aurora/blob/7b969982306e1498a8cbe6e5da9bde743acd8fc5/drivers/gpu/drm/asahi/g15/command.rs)
+  consumes the private structs, not those in the canonical header. Comparing
+  the latter alone does not qualify this backend.
+
+The compatibility path recognizes only already-admitted G15S/G15C identities
+with one of those two exact feature words, on direct DRM. It normalizes the
+features once before VM creation and converts packets at submission. It copies
+the shared prefixes, verifies every removed timestamp-copy byte is zero, moves
+the complete remaining tail without discarding nonzero fields, and preserves
+command headers, dependency barriers, attachments, queue IDs and sync objects.
+Kernel validation still checks all unsupported fields and GPU references.
+
+The caller's command buffer is unchanged. Temporary packet storage lives until
+the synchronous submit ioctl returns. Unknown signatures, mixed feature words,
+truncated/unrecognized packets, output exhaustion and nonzero copy slots are
+rejected. No kernel flag, GPU identity gate, VA reservation or firmware check
+is bypassed. No feature bits are changed in the kernel. This is compatibility
+with these known experimental contracts, not general ABI negotiation.
+
+`asahi-g15-wire` checks all 65,536 low feature combinations, identity refusals,
+both feature normalizations, every current render/compute packet extent,
+retained tail/barrier bytes, a mixed attachment/render/compute stream, all input
+truncations, output bounds and every removed byte's nonzero refusal. The
+existing canonical ABI/admission controls remain in place.
+
+At preparation time the updated x86_64 build passed all 92 Asahi tests.
+Native ARM64 packaging, the three-Mac reboot/readback/benchmark repeat, and
+J613 revised-layout hardware qualification remain pending. The initial M1
+boots passed on the preceding integration; they do not qualify this follow-up.
+No full CTS pass or sustained-performance qualification is claimed.

 # SiliconForest Mesa validation
 
+## Retained Omacom G15 wire follow-up
+
+The first physical J516S attempt of the integration below found that
+`omacom/linux-aurora@7b969982306e` still returns the separate G15 `0x3e`
+contract, not the canonical high-bit contract. The admission check stopped
+before VM creation; the old Mesa and default kernel were restored. The
+canonical-header comparison below was insufficient to establish G15 backend
+compatibility.
+
+`agx_g15_wire.c` now selects the exact retained G15S/G15C signatures, normalizes
+their feature assignments and converts every hardware packet into the backend's
+actual layout. Nonzero timestamp-copy slots and unknown signatures/packets fail
+closed. Air, G17, M1/M2 and virtio retain their existing packet paths. See
+[the contract and qualification notes](SILICONFOREST-G15-WIRE.md).
+
+The updated x86_64 build passes **92 registered Asahi tests**, including exact
+feature-signature, packet/prior/barrier, truncation and timestamp-copy refusal
+controls. The physical qualification of this follow-up is pending; the original
+receipts below describe the earlier integration head, not this source change.

Subject: [PATCH 45/53] Record three-Mac qualification of the retained G15 wire
 integration

Record actual package and driver hashes, pixel-readback checks and matched Quake results. Preserve the failed overall OMT verdict, initial ABI refusal and outstanding Air/full-CTS qualification. Correct the stale comment about the removed Mesa Air opt-in.

Tested production source is 97a65d845f39418aecc693dcaf9dcb14a05849f6; this follow-up changes documentation and one comment only.

+# Omacom Mesa CI
+
+Proposed integration CI, vetted first in `chriskearney/omacom-mesa`.
+No CODEOWNERS, Omacom repository settings, package source pins, or driver code are changed.
+
+## PR checks
+
+`ci / result` is the single required check. It always runs and fails on failures,
+cancellations, absent planner output or unexpected skips. The workflow has no
+path/branch filters on PRs, supports `merge_group`, and tests GitHub's checked-out
+merge commit rather than replacing it with the PR head. New PR commits cancel
+older PR runs; queued merges and post-merge builds do not cancel one another.
+
+Every PR runs production CPU fixtures, workflow lint and negative CI-control tests.
+Only a small documentation allowlist can skip native builds on PRs. Unknown paths,
+CI files, dependency metadata and every source change build both architectures.
+Merge-queue, manual and integration-branch push runs always build both.
+
+The parallel x86_64 and native aarch64 jobs use hosted Ubuntu 26.04, a matching
+LLVM/Clang/translator 22 toolchain and hash-pinned Meson 1.10.2. Two build workers
+limit peak memory. Compiler tools come from the same source; the final
+Asahi/Zink/Honeykrisp driver build disables LLVM and SPIRV-Tools linkage. It runs
+all configured Meson tests, then the existing no-submit drm-shim admission,
+pipeline and memory-map probes with Vulkan validation. Installed ELF dependencies
+are checked before a manifest is created. CPU/shim success is not GPU or CTS proof.
+
+Ccache speeds up subsequent PR revisions. Keys include architecture and build
+configuration, and GitHub isolates PR cache writes to each PR ref. Post-merge
+builds disable ccache and do not restore PR caches. No build directory, prebuilt
+shader tool or driver binary is shared between runs. Timeouts, bounded cache size
+and artifact retention limit cost. Exact cold/warm timings are measured in the
+personal-fork trial, not promised in advance.
+
+## Delivery and release
+
+A successful push to `integration/aurora` retains a staged ARM driver candidate
+and manifest, not an Arch package or automatic release. The manifest identifies
+the exact commit, runner architecture, run/attempt, per-file SHA-256, tested suites
+and installed toolchain packages. Failure artifacts retain Meson configure logs,
+test logs and JUnit evidence. Artifacts have 14-day retention.
+
+These are integration/debug builds with assertions. Shipping remains in
+`omarchy-pkgs`: pin an exact Omacom source commit, build the actual split packages
+with its production flags, obtain relevant hardware/CTS qualification and the
+normal maintainer release approval. Do not publish a PR artifact or assume a
+hosted ARM CPU is an Apple GPU. A new compiler/kernel contract needs new hardware
+results. Existing M3 Air and full CTS limitations remain.
+
+PR code runs only on disposable GitHub-hosted runners with a read-only token,
+no secrets, no retained checkout credentials and full-SHA action pins. There is no
+`pull_request_target`, privileged `workflow_run`, automatic lab access, OIDC or
+package-write permission. Action pin updates should be reviewed like source.
+
+## Maintainer rollout after the trial
+
+1. Establish Omacom's intended `integration/aurora` base and land this workflow there.
+2. Require the exact `ci / result` check from the GitHub Actions app (ID 15368).
+   Do not require optional matrix job names or the old lightweight check.
+3. Require PR review and approval of the latest push; disallow branch deletion and
+   force-pushes. Merge queues can use this workflow's `merge_group` coverage.
+4. Confirm a failing PR is blocked, a docs-only PR succeeds without build-pending
+   checks, and a merge-group run produces the same required context before release.
+
+CODEOWNERS and owner-review settings are deliberately outside this change, per
+Chris's hold. Workflow files and CI-control code are PR-editable, so the required
+status check alone is not tamper-proof: human review of workflow/gate changes or
+an organization-controlled required workflow is still necessary. Required status
+checks cannot enforce a numeric hardware/CTS result that this workflow never ran.

Subject: [PATCH 47/53] ci: cover late shader lowering and pinned kernel
 layouts

Compile real float-to-int64 and perspective-offset Vulkan pipelines on five emulated device profiles without submitting GPU work. Check the pinned public kernel UAPI, stop expensive jobs after fast failures, and fix ccache boolean setup.

Subject: [PATCH 48/53] ci: install SPIR-V development files and use hosted CPU
 capacity

Ubuntu26.04 splits SPIRV-Tools development metadata out of the command-line package. Include its development package and production optional system interfaces; use four bounded compiler workers.

Subject: [PATCH 49/53] ci: attest gated ARM archives and complete the hosted
 development environment

Only promote an ARM staging archive after both architectures and the required gate pass. Preserve symlinks and modes, pin the linter source, make caches optional and PR-only, and install split Wayland/libclc development/runtime dependencies explicitly.

Subject: [PATCH 51/53] ci: build all wrapped test executables and shorten the
 fast path

Meson default builds omit build_by_default:false test dependencies. Build all registered test dependencies explicitly before running the full suite, preserve useful PR compiler caches after test failures, verify a prebuilt linter instead of compiling it, and sparsely check out control scripts. Cover both signed and unsigned float-to-int64 paths.
