Jul 1, 2025July 2025: Delivered stability and correctness improvements to SIP debugging paths in intel/intel-graphics-compiler. Implemented a CR0 modification guard so cr0 changes occur only during SIP debug exit, preventing unintended CR0 state changes across debug paths. Updated MaskCtl alignment to the latest instruction set for Xe3_SIPDebugBindless.h, improving accuracy and compatibility of SIP debug bindless mode. These changes reduce production risk, improve debugging reliability, and lay groundwork for future hardware instruction support. Key outcomes include safer debug state transitions, more predictable SIP behavior, and enhanced maintainability of the debug code.

Jun 1, 2025June 2025 focused on delivering Xe3 SIP kernel configuration support for the intel/intel-graphics-compiler repository. This work introduces hardware-specific SIP configurations (1x4 and 2x6 tiles), adds dedicated header files, and wires configuration data into SystemThread.cpp and SystemThread.h to enable precise SIP operations on Xe3 hardware. A dedicated commit implements the wmtp SIP based on config. This lays the groundwork for more efficient system-thread execution and Xe3-specific optimizations.
