dma-buf: add DMA_RESV_USAGE_BOOKKEEP v3

2022-04-07T10:53:54Z

Add an usage for submissions independent of implicit sync but still interesting for memory management. v2: cleanup the kerneldoc a bit v3: separate amdgpu changes from this Signed-off-by: Christian König Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220407085946.744568-10-christian.koenig@amd.com

dma-buf: add enum dma_resv_usage v4

2022-04-07T10:53:53Z

This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.

drm/amdgpu: rework TLB flushing

2022-03-25T16:40:51Z

Instead of tracking the VM updates through the dependencies just use a sequence counter for page table updates which indicates the need to flush the TLB. This reduces the need to flush the TLB drastically. v2: squash in NULL check fix (Christian) Signed-off-by: Christian König Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: simplify VM update tracking a bit

2022-03-25T16:40:26Z

Store the 64bit sequence directly. Makes it simpler to use and saves a bit of fence reference counting overhead. Signed-off-by: Christian König Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: use dma_fence_chain_contained

dma-buf: rename and cleanup dma_resv_get_list v2

2021-06-06T09:18:19Z

When the comment needs to state explicitly that this is doesn't get a reference to the object then the function is named rather badly. Rename the function and use it in even more places. v2: use dma_resv_shared_list as new name Signed-off-by: Christian König Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210602111714.212426-5-christian.koenig@amd.com

When the comment needs to state explicitly that this doesn't get a reference to the object then the function is named rather badly. Rename the function and use rcu_dereference_check(), this way it can be used from both rcu as well as lock protected critical sections. v2: improve kerneldoc as suggested by Daniel v3: use dma_resv_excl_fence as function name Signed-off-by: Christian König Acked-by: Daniel Vetter Reviewed-by: Jason Ekstrand Link: https://patchwork.freedesktop.org/patch/msgid/20210602111714.212426-4-christian.koenig@amd.com
