Hi, This is continuation of the first and second submission of Intel Xe GPU debug support: v1: https://lists.freedesktop.org/archives/intel-xe/2024-July/043605.html v2: https://lists.freedesktop.org/archives/intel-xe/2024-October/052260.html New features in v3: - EXEC_QUEUE_PLACEMENT events providing detailed information about engines participating on exec queue. (Dominik Grzegorzek) - EU thread page fault support (Gwan-gyeong Mun) - Fixed access to VRAM backed storage (Matthew Brost) Essential for BMG enabling. This work was already merged into xe driver and eudebug takes advantage of that (ttm_bo_access). [8]. - Support for Pantherlake (Dominik Grzegorzek) v3 supports: - Lunarlake (LNL) - Battlemage (BMG) - Pantherlake (PTL) Thanks to all contributors! Latest code can be found in: [1] https://gitlab.freedesktop.org/miku/kernel/-/tree/eudebug-dev Branch for this submission: [2] https://gitlab.freedesktop.org/miku/kernel/-/tree/eudebug-v3 README/instructions: [3] https://gitlab.freedesktop.org/miku/kernel IGT tests (needs config switch 'xe_eudebug' to be set) [4] https://gitlab.freedesktop.org/drm/igt-gpu-tools.git https://gitlab.freedesktop.org/gfx-ci/i915-infra/-/blob/master/kconfig/debug.kconfig The user for this uapi: [5] https://github.com/intel/compute-runtime Event loop and thread control interaction can be found at: https://github.com/intel/compute-runtime/tree/master/level_zero/tools/source/debug/linux/xe And the wrappers in: https://github.com/intel/compute-runtime/tree/master/shared/source/os_interface/linux/xe https://github.com/intel/compute-runtime/blob/master/shared/source/os_interface/linux/xe/ioctl_helper_xe_debugger.cpp Note that the XE support is disabled by default and you will need NEO_ENABLE_XE_EU_DEBUG_SUPPORT enabled in order to test. GDB support: [6] https://github.com/intel/gdb/tree/upstream/intelgt-mvp [7] https://github.com/intel/gdb/tree/upstream/intelgt-mvp-plus GDB is preparing their own mailing list submission with above and based on v3. I will reply to this cover letter and update README when it happens.
