Nov 1, 2025November 2025 – Intel Compute Runtime: Key progress in memory management, deadlock avoidance, and OpenCL compatibility. Delivered a feature to remap virtual memory allocations when access attributes change and to extend memory mapping to include access attributes, enhancing correctness, stability, and security. Fixed a potential CSR deadlock by releasing the CSR lock before waiting for command queue completion, improving throughput and reliability. Improved OpenCL compatibility by ensuring MSAA sharing is not passed to compile for CL versions below 1.2, reducing build issues and broadening support.

Focused on hardware-conditional safety, synchronization correctness, and resource lifecycle management. Depth Image Blit Safety and Compatibility prevents unsafe blits on depth images when not supported and uses ReleaseHelper gating to abort when disallowed, improving stability across ARL and other configurations (commits a19fa245ab287ae7fde7d16c593e2f0b41f37f05; 85ed1a15e460f456a86937dd13d3c26b8f5a1052). Synchronization correctness for post-sync barriers ensures a pipe control with stall is inserted before barriers with post-sync operations, adopting immediateData PostSyncMode for increased accuracy across command lists and queues (commit e6f3ebce5d8edcaa5109bf07a0ecb066f6d7ec0a). Residency makeResident failure handling clears the residency allocationsForResidency container on failure to prevent leaks, with tests added (commit 577c99fe9cc3d287014143783701e9047633ea60).
