ci(vulkan): every L7 ray-query suite runs nightly on lavapipe, and a case that did not run fails the job (#1294) - #1633
Merged
Conversation
…ease (#1294) On VK_TIMEOUT, VulkanOneShot::Submit destroyed the fence and freed the command buffer while the submission could still be executing (VUID-vkDestroyFence-fence-01120, VUID-vkFreeCommandBuffers-pCommandBuffers-00047), and UploadToBuffer then destroyed the staging buffer under a copy that might still be reading it. It now waits without a timeout, as VulkanContext's flush already does, until the work retires or the device is lost, and still reports false/Submitted. An error from that second wait leaks the fence and command buffer instead of releasing them in flight. The injected timeout now waits for real with a zero budget, so the existing fence-wait injection tests run the drain against work that may still be pending.

…ice (#1294) 8 of 9 ReSTIRPTDevice cases failed on lavapipe 26.2.0 at the fixture's own 10 s vkWaitForFences on their first draw. Timed with the wait unbounded, that draw waits 38-41 s and every later draw on the same pipeline under 6 ms: llvmpipe JIT-compiles the fragment shader on the queue thread at its first draw. The work is not slow, so the workload stays as it is. DeviceFenceWaitBudgetNs (VulkanTestSupport.h) gives hardware 10 s and a software ICD 300 s, classified by VulkanCapabilities::Evaluate's IsSoftware, not an environment variable. All 9 cases pass on lavapipe and on an RTX 4090. With the stale 2.0 flags lane from #1288 restored, the near-specular metal (0.0095 vs 0.650) and glossy Cornell (0.037 vs 0.113) arms still go red on lavapipe.

…l if one did not run (#1294) vulkan-software.yml's filter now includes RayTracingDevice.*, GpuPathTracerDevice.* and ReSTIRPTDevice.*. A new step requires, from the gtest XML, that every case those suites define executed: the defined set comes from --gtest_list_tests, so a case a filter dropped counts as not run. The one exemption is the opt-in VegetationDetailedVersusCardExperiment. --olo-require-vulkan alone cannot do this, because the fixtures skip after the device gate and the Vulkan* suites keep the run "exercised". The gate is scripts/vulkan_ray_query_coverage.py, extracted from Windows.yml's inline #1299 reporter, which now calls it in report mode and adds GpuPathTracerDevice to its filter. The old heredoc wrote a literal "\n" into the job summary instead of a line break. A new ray_query_off dispatch input sets OLO_VULKAN_NO_RAY_TRACING, the negative control the gate must turn red.

Explanation
The changes implement a lavapipe nightly run and a per-case missing-execution gate for
#1294. The September amendment to#1294still requires a usable hardware RT runner or an explicitly authorized scheduled developer-device run. It also requires recording the last executed commit, backend/driver/extensions, execution counts, and required-case coverage age. The workflow provides no hardware RT or developer-device run, and the reporter does not establish a coverage-age record or include extension fields in its selected capability lines.Resolution
Provide the required hardware RT runner or an explicitly authorized scheduled developer-device run. Make that designated run fail when a required case does not execute. Record the required commit, backend/driver/extensions, executed/passed/failed/skipped counts, and coverage age. Alternatively, update
#1294's active requirements before treating the lavapipe-only scope as complete.

- Around line 218-234: Update `VulkanOneShot::Submit` to distinguish a failed
drain wait from other unsuccessful submissions, and set that outcome when the
drain wait fails. In `UploadToBuffer`, retain the staging buffer for this
outcome instead of destroying it; preserve cleanup when the drain succeeds or
the submission was never accepted.

- Line 158: Validate the CLI arguments before parsing the report: reject
required mode when --expected-list is missing, while preserving XML-only report

… keeps the staging buffer (#1294) Review finding on #1633: when the unbounded drain wait itself errors, Submit leaked the fence and command buffer but UploadToBuffer still destroyed the staging buffer the copy may be reading. Submit now waits for the queue to go idle, which proves the submission retired for every caller. Only when that fails too does it report the new Outcome::DrainFailed, and UploadToBuffer then leaks its staging buffer alongside the fence and command buffer.

…e set (#1294) Review findings on #1633: --require without --expected-list now errors, since a dropped case would be absent from both sides; and the workflow fails the step if --gtest_list_tests exits nonzero, before a partial list can reach the gate. The step reads BUILD_TYPE from the environment instead of expanding the template into the script. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Closes #1294 once the cells below are green. The PR body states the scope decision, as the issue asks.
Scope, as decided by the user on 2026-10-18
lavapipe only. No self-hosted RTX runner and no scheduled run on a developer box. Issue item 3 is dropped by that decision, and item 2 becomes "every L7 ray-query suite executes on lavapipe nightly, and a designated run fails when a case did not execute."
What changes
vulkan-software.ymlrunsRayTracingDevice.*,GpuPathTracerDevice.*andReSTIRPTDevice.*nightly on lavapipe 26.2.0. A new step, Require every L7 ray-query case to execute, fails the job when any case those suites define did not execute. The defined set comes from--gtest_list_tests, so a case a filter dropped is reported did not run instead of disappearing from the XML. The one exemption is the opt-inRayTracingDevice.VegetationDetailedVersusCardExperiment.--olo-require-vulkancould not do this: the fixtures skip after the device gate, and theVulkan*suites keep the run "exercised" (measured:PARTIAL - 138 of 178, exit 0, with ray query forced off).ReSTIR_PTdraw on a fresh lavapipe device waits 38-41 s and every later draw under 6 ms: llvmpipe JIT-compiles the fragment shader on the queue thread at its first draw. The fixture's fence budget now comes from the device (DeviceFenceWaitBudgetNs: 10 s hardware, 300 s software, classified byVulkanCapabilities::Evaluate().IsSoftware). No workload was shrunk.scripts/vulkan_ray_query_coverage.pyis the one reporter.Windows.yml's Renderer bug batch: Vulkan arena and GPU Scene fixes #1299 step now calls it in report mode (and addsGpuPathTracerDeviceto its filter). The old inline heredoc wrote a literal\ninto the job summary. Unit-tested inscripts/test_vulkan_ray_query_coverage.py, which runs in both workflows.ray_query_offsetsOLO_VULKAN_NO_RAY_TRACING=1(the gate's negative control). Dispatch runs get their own concurrency group, so two on one branch no longer cancel each other.Bug fixed on the way (own commit)
VulkanOneShot::Submitdestroyed its fence and freed its command buffer after a failed fence wait while the submission could still be executing (VUID-vkDestroyFence-fence-01120, VUID-vkFreeCommandBuffers-pCommandBuffers-00047), andUploadToBufferthen destroyed the staging buffer under the copy. It now drains (waits until retired or device lost) before release, asVulkanContext's flush already does, and still returnsfalse/Submitted. The injected timeout now does a real zero-budget wait, so the existing injection tests exercise the drain.Verification
