* drm/amdgpu: nuke the VM PD/PT shadow handlingChristian König2024-09-181-17/+2
| | | | | | | | | | | | | | This was only used as workaround for recovering the page tables after VRAM was lost and is no longer necessary after the function amdgpu_vm_bo_reset_state_machine() started to do the same. Compute never used shadows either, so the only proplematic case left is SVM and that is most likely not recoverable in any way when VRAM is lost.

* drm/amdgpu: re-work VM syncingChristian König2024-09-061-12/+4
| | | | | | | | | | | | | | Rework how VM operations synchronize to submissions. Provide an amdgpu_sync container to the backends instead of an reservation object and fill in the amdgpu_sync object in the higher layers of the code. No intended functional change, just prepares for upcomming changes.

* drm/amdgpu: implement TLB flush fenceChristian Koenig2024-03-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that when (for example) 4k pages are replaced with a single 2M page we need to wait for change to be flushed out by invalidating the TLB before the PT can be freed. Solve this by moving the TLB flush into a DMA-fence object which can be used to delay the freeing of the PT BOs until it is signaled. V2: (Shashank) - rebase - set dma_fence_error only in case of error - add tlb_flush fence only when PT/PD BO is locked (Felix) - use vm->pasid when f is NULL (Mukul) V4: - add a wait for (f->dependency) in tlb_fence_work (Christian) - move the misplaced fence_create call to the end (Philip) V5: - free the f->dependency properly V6: (Shashank) - light code movement, moved all the clean-up in previous patch - introduce params.needs_flush and its usage in this patch - rebase without TLB HW sequence patch V7: - Keep the vm->last_update_fence and tlb_cb code until we can fix the HW sequencing (Christian) - Move all the tlb_fence related code in a separate function so that its easier to read and review V9: Addressed review comments from Christian - start PT update only when we have callback memory allocated V10: - handle device unlock in OOM case (Christian, Mukul) - added Christian's R-B Cc: Christian Koenig <[email protected]> Cc: Felix Kuehling <[email protected]> Cc: Rajneesh Bhardwaj <[email protected]> Cc: Alex Deucher <[email protected]> Acked-by: Felix Kuehling <[email protected]> Acked-by: Rajneesh Bhardwaj <[email protected]> Tested-by: Rajneesh Bhardwaj <[email protected]> Reviewed-by: Shashank Sharma <[email protected]> Reviewed-by: Christian Koenig <[email protected]> Signed-off-by: Christian Koenig <[email protected]> Signed-off-by: Shashank Sharma <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
