June 2026 monthly summary for aobolensk/openvino focusing on cross-driver reliability and regression testing for GPU kernels. Delivered a driver-agnostic regression test for __local block-read kernel compilation across GPU drivers, addressing a CI gap where field failures were driver-version dependent. This work builds on prior fixes to clBuildProgram and the __local-pointer overload transitions in NEO, and strengthens release confidence for GPU kernels used in production wheels. Impact: reduces field regressions for kernel compilation, improves CI coverage across driver variations, and provides a reproducible test path for driver-specific issues. Draft validation status with plan to green and DCO sign-off before finalization.

May 2026: Implemented GPU kernel compatibility fixes across the OpenVINO GPU plugin to maintain reliable OpenCL inference on Gen 9.5+ Intel hardware with modern Compute Runtime (NEO) drivers. Delivered targeted patches replacing deprecated intel_sub_group_block_read overloads with per-lane local indexing, preserving synchronization and performance without requiring new extensions. The work spans two repositories with four kernels: fully_connected_gpu_gemv.cl (Gen 9.5+), lora_opt.cl, lora_horizontal_fused.cl, and moe_3gemm_swiglu_mlp.cl. Commits include 5071f09246f336eb019c4b03ab061f3b3108f515 and b9bad1e016276517b81e65f152326af9ab85e188.
