Initialize the desktop replay Request from the three iterationRP environment flags before loading MobileGL. Without this, the Request defaults caused the replay core to unset CI's exported flags, leaving all repairs disabled despite the workflow configuration.
Run the lavapipe Program 203 golden test with the same subgroup scratch, derived topology, and missing-barrier repairs as the iterationRP retrace matrix. This keeps the prerequisite integration job from failing before retrace jobs can start.
Program 203 reuses prefixSumCache for a second subgroup reduction before every workgroup invocation has consumed the first result. Add a fingerprint-gated SPIR-V pass that inserts the missing Workgroup acquire-release barrier while preserving native subgroup operations.
Keep the repair opt-in behind MOBILEGL_ITERATIONRP_FIX_BARRIER, cover insertion, pass-through, and idempotence, and enable it together with the existing iterationRP subgroup repairs for the matching Linux and Android CI retraces.
Add a deterministic iterationRP Program 203 fixture that dispatches the original shader and compares every RG16F texel against fixed half-float golden bits. This catches both a wrong exposure result and collateral writes without retaining a serial reference shader.
Make MobileGLIntegrationTest runnable as a standalone Android executable by linking the shared MobileGL library and backing EGL with an AImageReader window; desktop keeps its static-library pbuffer path.
Validation: Adreno 830 passes with 0/262656 mismatches; lavapipe reproduces the current reduction defect with 1/262656 mismatches at the exposure texel.
Final audit round over the DirectGLES scratch/shadow mechanisms; three verified
defects fixed:
- ~ScopedEmulationDrawState restored the APPLICATION's per-buffer colour masks,
not what SyncRenderState actually pushed: a widened attachment's alpha-off
doctoring (g_syncedColorMaskAlphaWidenMask) was dropped while the memo still
claimed it applied, so the next sync early-outed and draws wrote fragment
alpha into the widened buffer - breaking the stored-alpha==1.0 invariant the
widen discipline exists to protect. The restore now re-applies the doctoring.
- The same restore loop gated on the core glColorMaski name only, while the sync
push falls back to glColorMaskiEXT/OES: EXT/OES-only devices were left holding
buffer 0's mask broadcast across every draw buffer with the shadow recording
the divergent set (never repaired). The restore now uses the same three-way
pointer fallback.
- ResolveThenBlit ran its resolve-into-scratch staging blit under the
application's scissor: a box not covering the scratch-origin rect clipped the
resolve silently (no GL error), and the second blit then copied stale scratch
renderbuffer texels into the destination. The staging blit now runs scissor-off
(shadow-tracked, like ScopedScissorDisable); the caller-visible blit keeps its
native scissor semantics.
Six more verified defects from the residual memo/cache mechanisms:
- Program resource cache (DirectVulkan reflection): glShaderStorageBlockBinding
deliberately does not bump the backend state version, and the SSO pipeline
composite is unnamed so the by-name in-place patch can never reach its slot -
the composite kept serving pre-rebind SSBO bindings. The cache now keys on the
program's block-binding version; a binding-only change re-applies the overrides
by name instead of re-running spirv-reflect. SetShaderStorageBlockBinding also
gains the equality bail-out its uniform-block sibling has, so the composite
mirror's replay stops churning the version every draw.
- LinkProgram's allowVSOnlyPrograms function-static latch never set its own
initialized flag (dead memo, re-read every call) - and completing it would have
frozen a per-backend capability across re-initialization. Replaced with a fresh
per-link read from the null-checked active backend.
- Query object registry: drained at full library teardown (DestroyAllQueryObjects,
mirroring DestroyAllSyncObjects) - undeleted queries and their backend wrappers
leaked across Destroy/Initialize cycles, stale ids stayed IsQuery == GL_TRUE in
the re-initialized library, and a later delete could hand the old backend's
wrapper to a different backend's DeleteBackendQuery.
- Converted vertex streams and the host-side EBO max-index scan now SyncGpuWrites
before reading the coherent mapping: XFB/SSBO/image writes are merely recorded
at that point, so the conversion read pre-write bytes (the restart-index
rewrite already synced; these two host reads did not).
- Zero-stride converted bindings: both converters rejected stride 0, making the
factory's documented single-element conversion unreachable and silently
dropping every draw using such a binding; the stride is substituted with the
element size for the one-element case.
- DemoteFloat64Pass block relayout: measurement queued into the module eagerly,
so a mid-struct failure left a half-relaid-out block (compacted offsets before
the failing member, 64-bit offsets after) while claiming the block was left
alone. Decoration writes are now collected and committed only when the whole
block measures successfully.
