Hi, Dave & Simona The drm-xe-next PR for this week:
Series highlights: - Support run ticks for multi-queue use case 11/11 patches pushed In multi-queue scenarios the CTX_TIMESTAMP represents run ticks of all queues combined. To determine individual queue run ticks, QUEUE TIMESTAMP must be used instead. The series adds support to read QUEUE TIMESTAMP for multi-queue use cases, including LRC snapshot support, trace events, and the infrastructure to capture queue run times for active queues. (Umesh Nerlige Ramappa, Matthew Brost) - Refactor functions implementing the blt batch 3/3 patches Functions implementing batch buffers for blitter instructions (MEM_SET, MEM_COPY, XY_FAST_COPY, XY_FAST_COLOR) used hardcoded fixed instruction lengths. Replaces these with a helper function that returns the correct length based on the platform, as preparatory work for upcoming platforms where these instruction lengths will increase. (Balasubramani Vivekanandan) - drm/xe/memirq: Update interrupt handler logic 2/2 patches A new programming note for memory-based interrupts was released. Updates the interrupt handler to follow the new note and stops enabling all GT_MI_USER_INTERRUPTs to avoid unnecessary empty processing cycles. (Michal Wajdeczko) - drm/xe/dma-buf: UAF and race condition fixes 2/2 patches Fixes two use-after-free and race conditions in the dma-buf import path. The invalidate_mappings hook could be called back into with a partially initialized or already freed buffer object. Fixes this by moving the attach step until after the buffer object is fully set up. (Matthew Auld) - drm/xe/multi_queue: Code refactor and cleanup 2/2 patches Removes a redundant assignment in guc_exec_queue_run_job and refactors the CGP_SYNC send path to reduce code size and improve clarity. (Niranjana Vishwanathapura) - More MERTOA WA's 4/4 patches Two hardware workarounds for the MERTOA OA unit. Wa_14026746987 restricts the supported OA format to XE_OAM_FORMAT_MPEC8u32_B8_C8. Wa_14026779378 blocks the SYS_MEM_LAT_MEASURE_EN bit to prevent memory corruption. Also includes a refactor of oa_unit_supports_oa_format and a new val argument to xe_oa_is_valid_config_reg.
