2024-01-15drm/xe/migrate: Fix CCS copy for small VRAM copy chunksThomas Hellström2-50/+80
Since the migrate code is using the identity map for addressing VRAM, copy chunks may become as small as 64K if the VRAM resource is fragmented. However, a chunk size smaller that 1MiB may lead to the *next* chunk's offset into the CCS metadata backup memory may not be page-aligned, and the XY_CTRL_SURF_COPY_BLT command can't handle that, and even if it could, the current code doesn't handle the offset calculaton correctly. To fix this, make sure we align the size of VRAM copy chunks to 1MiB. If the remaining data to copy is smaller than that, that's not a problem, so use the remaining size. If the VRAM copy cunk becomes fragmented due to the size alignment restriction, don't use the identity map, but instead emit PTEs into the page-table like we do for system memory. v2: - Rebase v3: - Future proof somewhat by taking into account the real data size to flat CCS metadata size ratio. (Matt Roper) - Invert a couple of if-statements for better readability. - Fix support for 4K-granularity VRAM sizes. (Tested on DG1). v4: - Fix up code comments - Fix debug printout format typo. v5: - Add a Fixes: tag.

2024-01-15drm/xe: Fix modifying exec_queue priority in xe_migrate_initBrian Welty4-9/+14
After exec_queue has been created, we cannot simply modify q->priority. This needs to be done by the backend via q->ops. However in this case, it would be more efficient to simply pass a flag when creating the exec_queue and set the desired priority upfront during queue creation. To that end: new flag EXEC_QUEUE_FLAG_HIGH_PRIORITY is introduced. The priority field is moved to be with other scheduling properties and is now exec_queue.sched_props.priority. This is no longer set to initial value by the backend, but is now set within __xe_exec_queue_create().
