drm/xe: Move suballocator init to after display init

2025-05-29T09:03:08+00:00

[ Upstream commit 380b0cdaa76bc8f5c16db16eaf48751e792ff041 ] No allocations should be done before we have had a chance to preserve the display fb.

drm/xe: Introduce xe_tile_init_early and use at earlier point in probe

2023-12-21T16:45:10+00:00

It also merges the GT (which is part of tile) initialization happening at xe_info_init with allocating other per-tile data structures into a common helper function. Signed-off-by: Michał Winiarski Reviewed-by: Matthew Brost Signed-off-by: Rodrigo Vivi

drm/xe: Add sysfs entry for tile

2023-12-21T16:35:06+00:00

We have recently introduced tile for each gpu, so lets add sysfs entry per tile for userspace to provide required information specific to tile. V5: - define ktype as const V4: - Reorder headers - Aravind V3: - Make API to return void and add drm_warn - Aravind V2: - Add logs in failure path Reviewed-by: Aravind Iddamsetty Signed-off-by: Tejas Upadhyay Signed-off-by: Rodrigo Vivi

drm/xe: Move migration from GT to tile

2023-12-19T23:34:15+00:00

Migration primarily focuses on the memory associated with a tile, so it makes more sense to track this at the tile level (especially since the driver was already skipping migration operations on media GTs). Note that the blitter engine used to perform the migration always lives in the tile's primary GT today. In theory that could change if media GTs ever start including blitter engines in the future, but we can extend the design if/when that happens in the future. v2: - Fix kunit test build - Kerneldoc parameter name update v3: - Removed leftover prototype for removed function. (Gustavo) - Remove unrelated / unwanted error handling change.

drm/xe: Move GGTT from GT to tile

2023-12-19T23:34:11+00:00

The GGTT exists at the tile level. When a tile contains multiple GTs, they share the same GGTT. v2: - Include some changes that were mis-squashed into the VRAM patch.
