Adds iter19 campaign-close doc (mesa-panvk-bifrost r7 ship, XFB packed-varying channel-extract fix). Also lands the r5 full dEQP-VK sweep scoreboard (2.26M tests, 97.65% runnable pass rate) that surfaced the holes_vert crash in the first place. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# r5 full dEQP-VK sweep — 2026-05-25
|
||
|
||
Driver under test: `mesa-panvk-bifrost-26.0.6.r5-1` (fragmentStoresAndAtomics flip)
|
||
Hardware: PineTab2 / RK3566 / Mali-G52 r1 MC1 (PAN_ARCH 7)
|
||
CTS: vulkan-cts-1.3.10.0 (commit 7aa3551)
|
||
Run host: ohm
|
||
Run window: 2026-05-24 ~22:00 → 2026-05-25 02:48 CEST (~5h wall)
|
||
|
||
## Corrected scoreboard
|
||
|
||
| Metric | Count | % of total |
|
||
|-----------------------|--------------|------------|
|
||
| Total tests | 2,258,378 | 100.00 |
|
||
| Passed | 553,447 | 24.51 |
|
||
| Failed | 13,318 | 0.59 |
|
||
| NotSupported | 1,691,613 | 74.90 |
|
||
| **Pass rate (runnable)** | - | **97.65%** |
|
||
|
||
| Group status | Count |
|
||
|------------------------------------|-------|
|
||
| Clean groups (0 failures) | 41/53 |
|
||
| Groups with failures | 12/53 |
|
||
| Watchdog-killed (data recovered) | 3/53 |
|
||
|
||
The 3 watchdog-killed groups (`api`, `subgroups`, `transform_feedback`) hit dEQP's
|
||
internal watchdog timer and got SIGKILL'd (exit=137), but the per-group `.qpa`
|
||
files contain all completed test results — totals were re-derived from those
|
||
qpa files directly. The wrapper's `elapsed=3s` field is misleading; the real
|
||
runs went the full distance.
|
||
|
||
## Failed groups (sorted by fail count)
|
||
|
||
| Group | Fails | Notes |
|
||
|---------------------|--------|--------------------------------------------------------------|
|
||
| image | 10,445 | 78% of all fails. Single biggest target. |
|
||
| subgroups | 2,342 | Bifrost is 4- or 8-wide warps; many fails likely arch-gap |
|
||
| glsl | 306 | |
|
||
| memory_model | 106 | Bifrost memory ordering — expected partial coverage |
|
||
| draw | 68 | |
|
||
| transform_feedback | 27 | All `resume_*` — **documented iter17 by-design gap** |
|
||
| compute | 8 | |
|
||
| pipeline | 5 | |
|
||
| descriptor_indexing | 4 | |
|
||
| api | 3 | |
|
||
| spirv_assembly | 3 | |
|
||
| info | 1 | |
|
||
|
||
## Watchdog-stop tests (last test attempted in each group)
|
||
|
||
| Group | Last test | Verdict |
|
||
|--------------------|-----------------------------------------------------------------------------|------------------|
|
||
| api | `dEQP-VK.api.device_init.create_instance_device_intentional_alloc_fail.basic` | watchdog (total time) |
|
||
| subgroups | `dEQP-VK.subgroups.clustered.graphics.subgroupclusteredadd_ivec3` | watchdog (touch interval) |
|
||
| transform_feedback | `dEQP-VK.transform_feedback.simple.holes_vert` | **userspace coredump, reproducible** — see #107 |
|
||
|
||
## transform_feedback 27 fails — all known by-design
|
||
|
||
Every fail is shape `dEQP-VK.transform_feedback.simple.resume_*` —
|
||
3 stream-count cells × {`resume`, `resume_beginqueryindexed_streamid_0`,
|
||
`resume_endqueryindexed_streamid_0`} × {256, 512, 131072}. All fail at
|
||
`vktTransformFeedbackSimpleTests.cpp:949` with `received:N expected:0`.
|
||
These match the iter17 closeout note ("remaining 81 fails are by-design
|
||
resume_* tests, transformFeedbackDraw=false"). The set here is a strict
|
||
subset of the 81; this run only hit the 27 cells that this sweep configuration
|
||
exercised. **No r5 regression on iter17 XFB.**
|
||
|
||
## Next actions
|
||
|
||
- **Phase 0 on `holes_vert` coredump** — userspace-only (dmesg clean), reproducible in isolation against r6 too. Tracked as task #107.
|
||
- **r7 candidate sort** — `image` group's 10,445 fails are the largest mass; needs Phase 0 evidence sort to see if it's one root cause replicated across format/dim cells or many.
|
||
|
||
## Provenance
|
||
|
||
- Raw per-group qpa + run.log: `ohm:/home/mfritsche/cts-results/r5_full/`
|
||
- Summary log: `ohm:/home/mfritsche/cts-results/r5_full/summary.log`
|
||
- Driver: `ohm:/usr/lib/panvk-bifrost/libvulkan_panfrost.so` (r5 then r6)
