drm/amdgpu: fix visible VRAM handling during faults

2024-05-02T14:32:41+00:00

[ Upstream commit a6ff969fe9cbf369e3cd0ac54261fec1122682ec ] When we removed the hacky start code check we actually didn't took into account that *all* VRAM pages needs to be CPU accessible. Clean up the code and unify the handling into a single helper which checks if the whole resource is CPU accessible. The only place where a partial check would make sense is during eviction, but that is neglitible.

drm/amdgpu: accommodate DOMAIN/PL_DOORBELL

2023-08-07T21:14:06+00:00

This patch adds changes: - to accommodate the new GEM domain for DOORBELLs - to accommodate the new TTM PL for DOORBELLs in order to manage doorbell pages as GEM object. V2: Addressed reviwe comments from Christian - drop the doorbell changes for pinning/unpinning - drop the doorbell changes for dma-buf map - drop the doorbell changes for sgt - no need to handle TTM_PL_FLAG_CONTIGUOUS for doorbell - add caching type for doorbell V3: - Removed unrelated empty line (Christian) - Add PL_DOORBELL in mem_type_to_domain() as well (Alex) Cc: Alex Deucher Cc: Christian Koenig Reviewed-by: Christian Koenig Signed-off-by: Alex Deucher Signed-off-by: Shashank Sharma

drm/amdgpu: Move vram, gtt & flash defines to amdgpu_ ttm & _psp.h

drm/amdgpu: Rename DRM schedulers in amdgpu TTM

2023-06-15T14:42:33+00:00

Rename mman.entity to mman.high_pr to make the distinction clearer that this is a high priority scheduler. Similarly, rename the recently added mman.delayed to mman.low_pr to make it clear it is a low priority scheduler. No functional change in this patch.

drm/amdgpu: Add a low priority scheduler for VRAM clearing

Add a low priority DRM scheduler for VRAM clearing instead of using the exisiting high priority scheduler. Use the high priority scheduler for migrations and evictions. Signed-off-by: Mukul Joshi Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Alloc memory of GPU support memory partition

2023-06-09T14:00:03+00:00

For dGPU mode VRAM allocation, create amdgpu_bo from amdgpu_vm->mem_id, to alloc from the correct memory range. For APU mode VRAM allocation, set alloc domain to GTT, and set bp->mem_id_plus1 from amdgpu_vm->mem_id + 1 to create amdgpu_bo, to allocate system memory from correct NUMA node. For GTT allocation, use mem_id -1 to allocate system memory from any NUMA nodes. Remove amdgpu_ttm_tt_set_mem_pool, to avoid the confusion that memory maybe allocated from different mem_id.

drm/amdkfd: Native mode memory partition support

2023-06-09T13:57:37+00:00

For native mode, after amdgpu_bo is created on CPU domain, then call amdgpu_ttm_tt_set_mem_pool to select the TTM pool using bo->mem_id. ttm_bo_validate will allocate the memory to the correct memory partition before mapping to GPUs.

2023-06-09T13:57:31+00:00

For native mode only, create TTM pool for each memory partition to store the NUMA node id, then the TTM pool will be selected using memory partition id to allocate memory from the correct partition.

Use the generic term fw_reserved_memory for FW reserve region. This region may also hold discovery TMR in addition to other reserve regions. This region size could be larger than discovery tmr size, hence don't change the discovery tmr size based on this. Signed-off-by: Lijo Lazar Reviewed-by: Le Ma Signed-off-by: Alex Deucher
