## 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)
