drm/amdgpu: fix ftrace event amdgpu_bo_move always move on same heap

2023-12-14T20:25:48Z

Issue: during evict or validate happened on amdgpu_bo, the 'from' and 'to' is always same in ftrace event of amdgpu_bo_move where calling the 'trace_amdgpu_bo_move', the comment says move_notify is called before move happens, but actually it is called after move happens, here the new_mem is same as bo->resource Fix: move trace_amdgpu_bo_move from move_notify to amdgpu_bo_move Signed-off-by: Wang, Beyond Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix AGP addressing when GART is not at 0

2023-11-29T21:49:22Z

This worked by luck if the GART aperture ended up at 0. When we ended up moving GART on some chips, the GART aperture ended up offsetting the AGP address since the resource->start is a GART offset, not an MC address. Fix this by moving the AGP address setup into amdgpu_bo_gpu_offset_no_check(). v2: check mem_type before checking agp v3: check if the ttm bo has a ttm_tt allocated yet Fixes: 67318cb84341 ("drm/amdgpu/gmc11: set gart placement GC11") Tested-by: Mario Limonciello Reported-by: Jesse Zhang Reported-by: Yifan Zhang Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: christian.koenig@amd.com Cc: mario.limonciello@amd.com

drm/amdgpu: fix AGP init order

The default AGP settings were overwriting the IP selected ones since the default was getting set after the IP ones were selected.

drm/amdgpu/gmc: set a default disable value for AGP

2023-09-26T21:00:22Z

To disable AGP, the start needs to be set to a higher value than the end. Set a default disable value for the AGP aperture and allow the IP specific GMC code to enable it selectively be calling amdgpu_gmc_agp_location(). Reviewed-by: Christian König Signed-off-by: Alex Deucher

Revert "drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar system"

2023-06-15T14:43:36Z

This reverts commit c105518679b6e87232874ffc989ec403bee59664. This patch disables the TOPDOWN flag for APU and few dGPU cards which has the VRAM size equal to the BAR size. When we enable the TOPDOWN flag, we get the free blocks at the highest available memory region and we don't split the lower order blocks. This change is required to keep off the fragmentation related issues particularly in ASIC which has VRAM space <= 500MiB Hence, we are reverting this patch.
