drm/amdgpu: check the GART table before invalidating TLB

2022-02-07T23:01:16+00:00

Bypass group programming (utcl2_harvest) aims to forbid UTCL2 to send invalidation command to harvested SE/SA. Once invalidation command comes into harvested SE/SA, SE/SA has no response and system hang. This patch is to add checking if the GART table is already allocated before invalidating TLB. The new procedure is as following: 1. Calling amdgpu_gtt_mgr_init() in amdgpu_ttm_init(). After this step GTT BOs can be allocated, but GART mappings are still ignored. 2. Calling amdgpu_gart_table_vram_alloc() from the GMC code. This allocates the GART backing store. 3. Initializing the hardware, and programming the backing store into VMID0 for all VMHUBs. 4. Calling amdgpu_gtt_mgr_recover() to make sure the table is updated with the GTT allocations done before it was allocated.

drm/amdgpu: remove gart.ready flag

2022-01-20T03:32:47+00:00

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. Signed-off-by: Christian König Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher

drm/amdgpu: recover gart table at resume

2022-01-11T20:44:26+00:00

Get rid off pin/unpin of gart BO at resume/suspend and instead pin only once and try to recover gart content at resume time. This is much more stable in case there is OOM situation at 2nd call to amdgpu_device_evict_resources() while evicting GART table. v3: remove gart recovery from other places v2: pin gart at amdgpu_gart_table_vram_alloc() Reviewed-by: Christian König Signed-off-by: Nirmoy Das Signed-off-by: Alex Deucher

drm/amdgpu: Put drm_dev_enter/exit outside hot codepath

2021-09-23T19:17:29+00:00

We hit soft hang while doing memory pressure test on one numa system. After a qucik look, this is because kfd invalid/valid userptr memory frequently with process_info lock hold. Looks like update page table mapping use too much cpu time. perf top says below, 75.81% [kernel] [k] __srcu_read_unlock 6.19% [amdgpu] [k] amdgpu_gmc_set_pte_pde 3.56% [kernel] [k] __srcu_read_lock 2.20% [amdgpu] [k] amdgpu_vm_cpu_update 2.20% [kernel] [k] __sg_page_iter_dma_next 2.15% [drm] [k] drm_dev_enter 1.70% [drm] [k] drm_prime_sg_to_dma_addr_array 1.18% [kernel] [k] __sg_alloc_table_from_pages 1.09% [drm] [k] drm_dev_exit So move drm_dev_enter/exit outside gmc code, instead let caller do it. They are gart_unbind, gart_map, vm_clear_bo, vm_update_pdes and gmc_init_pdb0. vm_bo_update_mapping already calls it.
