Jun 1, 2025June 2025 monthly summary for intel/compute-runtime. Delivered reliability enhancements across three areas: (1) Timestamp packet handling safety—bounds checking and safe resets to prevent out-of-bounds access and state inconsistencies, with corresponding test updates; (2) IPC handle tracking and memory data management—centralized handle tracking, type-safe IPC data handling with templates, and a new opaque IPC memory structure to support pidfd/socket IPC; (3) Experimental DRM format modifiers interfaces—initial interfaces to query, create, and import images and buffers with DRM format modifiers to improve Linux graphics API interoperability. Commit traceability: Timestamp fixes (953639411a1fe6539f37d06fb2e1f5cca019aa65, 8e45fb880f064ab0d3066c33c9db431d5d420028); IPC refactors and templates (253764f4400289bfac7e80972f263b94509c86ca, e1b33a657c3339fbc089ccce98fb040c1f57ca3c, aaa01c06f99e844a8f5cf439b7d60613f28665ef, 39b28474ae13885bcf55366d4a3190cfe3da02ba); DRM modifiers (26ab4fc7b7acdecb8c818b4bfa881d6489ea1d67).
