2024-04-23drm/amdgpu: Fix the ring buffer size for queue VM flushPrike Liang
Here are the corrections needed for the queue ring buffer size calculation for the following cases: - Remove the KIQ VM flush ring usage. - Add the invalidate TLBs packet for gfx10 and gfx11 queue. - There's no VM flush and PFP sync, so remove the gfx9 real ring and compute ring buffer usage.

2024-04-23drm/amdkfd: Add VRAM accounting for SVM migrationMukul Joshi
Do VRAM accounting when doing migrations to vram to make sure there is enough available VRAM and migrating to VRAM doesn't evict other possible non-unified memory BOs. If migrating to VRAM fails, driver can fall back to using system memory seamlessly.

2024-04-23drm/amd/pm: Restore config space after resetLijo Lazar
During mode-2 reset, pci config space registers are affected at device side. However, certain platforms have switches which assign virtual BAR addresses and returns the same even after device is reset. This affects pci_restore_state() as it doesn't issue another config write, if the value read is same as the saved value. Add a workaround to write saved config space values from driver side. Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence restrict the workaround only to those.

2024-04-22drm/buddy: Implement tracking clear page featureArunpravin Paneer Selvam
- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).

2024-04-17drm/amdgpu: remove invalid resource->start check v2Christian König
The majority of those where removed in the commit aed01a68047b ("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2") But this one was missed because it's working on the resource and not the BO. Since we also no longer use a fake start address for visible BOs this will now trigger invalid mapping errors. v2: also remove the unused variable Signed-off-by: Christian König <christian.koenig@amd.com> Fixes: aed01a68047b ("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2") CC: stable@vger.kernel.org Acked-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
