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.
