2023-06-09drm/amdgpu: Allocate GART table in RAM for AMD APUFelix Kuehling1-0/+2
Some AMD APUs may not have a dedicated VRAM. On such platforms the GART table should be allocated on the system memory. When real vram size is zero, place the GART table in system memory and create an SG BO to make it GPU accessible. v2: fix includes Reviewed-by: Felix Kuehling <[email protected]> (rajneesh: removed set_memory_wc workaround) Signed-off-by: Rajneesh Bhardwaj <[email protected]> Signed-off-by: Harish Kasiviswanathan <[email protected]> Signed-off-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2022-01-19drm/amdgpu: remove gart.ready flagChristian König1-8/+7
That's just a leftover from old radeon days and was preventing CS and GART bindings before the hardware was initialized. But nowdays that is perfectly valid. The only thing we need to warn about are GART binding before the table is even allocated.

Don't flush gart changes after recovering each BO instead do it after recovering all the BOs. Flishing gart also needed for amdgpu_ttm_alloc_gart(). v4: use containerof to retrieve adev struct. v3: rename amdgpu_gart_tlb_flush() -> amdgpu_gart_invalidate_tlb(). v2: abstract out gart tlb flushing logic to amdgpu_gart.c Signed-off-by: Nirmoy Das <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2021-05-19drm/amdgpu: Handle IOMMU enabled case.Andrey Grodzovsky1-1/+1
Problem: Handle all DMA IOMMU group related dependencies before the group is removed. Those manifest themself in that when IOMMU enabled DMA map/unmap is dependent on the presence of IOMMU group the device belongs to but, this group is released once the device is removed from PCI topology. Fix: Expedite all such unmap operations to pci remove driver callback. v5: Drop IOMMU notifier and switch to lockless call to ttm_tt_unpopulate v6: Drop the BO unamp list v7: Drop amdgpu_gart_fini In amdgpu_ih_ring_fini do uncinditional check (!ih->ring) to avoid freeing uniniitalized rings. Call amdgpu_ih_ring_fini unconditionally. v8: Add deatiled explanation Signed-off-by: Andrey Grodzovsky <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
