The idea behind this patch is to delay the freeing of PT entry objects until the TLB flush is done. This patch: - Adds a tlb_flush_waitlist in amdgpu_vm_update_params which will keep the objects that need to be freed after tlb_flush. - Adds PT entries in this list in amdgpu_vm_ptes_update after finding the PT entry. - Changes functionality of amdgpu_vm_pt_free_dfs from (df_search + free) to simply freeing of the BOs, also renames it to amdgpu_vm_pt_free_list to reflect this same. - Exports function amdgpu_vm_pt_free_list to be called directly. - Calls amdgpu_vm_pt_free_list directly from amdgpu_vm_update_range. V2: rebase V4: Addressed review comments from Christian - add only locked PTEs entries in TLB flush waitlist. - do not create a separate function for list flush. - do not create a new lock for TLB flush. - there is no need to wait on tlb_flush_fence exclusively. V5: Addressed review comments from Christian - change the amdgpu_vm_pt_free_dfs's functionality to simple freeing of the objects and rename it. - add all the PTE objects in params->tlb_flush_waitlist - let amdgpu_vm_pt_free_root handle the freeing of BOs independently - call amdgpu_vm_pt_free_list directly V6: Rebase V7: Rebase V8: Added a NULL check to fix this backtrace issue: [ 415.351447] BUG: kernel NULL pointer dereference, address: 0000000000000008 [ 415.359245] #PF: supervisor write access in kernel mode [ 415.365081] #PF: error_code(0x0002) - not-present page [ 415.370817] PGD 101259067 P4D 101259067 PUD 10125a067 PMD 0 [ 415.377140] Oops: 0002 [#1] PREEMPT SMP NOPTI [ 415.382004] CPU: 0 PID: 25481 Comm: test_with_MPI.e Tainted: G OE 5.18.2-mi300-build-140423-ubuntu-22.04+ #24 [ 415.394437] Hardware name: AMD Corporation Sh51p/Sh51p, BIOS RMO1001AS 02/21/2024 [ 415.402797] RIP: 0010:amdgpu_vm_ptes_update+0x6fd/0xa10 [amdgpu] [ 415.409648] Code: 4c 89 ff 4d 8d 66 30 e8 f1 ed ff ff 48 85 db 74 42 48 39 5d a0 74 40 48 8b 53 20 48 8b 4b 18 48 8d 43 18 48 8d 75 b0 4c 89 ff <48 > 89 51 08 48 89 0a 49 8b 56 30 48 89 42 08 48 89 53 18 4c 89 63 [ 415.430621] RSP: 0018:ffffc9000401f990 EFLAGS: 00010287 [ 415.436456] RAX: ffff888147bb82f0 RBX: ffff888147bb82d8 RCX: 0000000000000000 [ 415.444426] RDX: 0000000000000000 RSI: ffffc9000401fa30 RDI: ffff888161f80000 [ 415.452397] RBP: ffffc9000401fa80 R08: 0000000000000000 R09: ffffc9000401fa00 [ 415.460368] R10: 00000007f0cc0000 R11: 00000007f0c85000 R12: ffffc9000401fb20 [ 415.468340] R13: 00000007f0d00000 R14: ffffc9000401faf0 R15: ffff888161f80000 [ 415.476312] FS: 00007f132ff89840(0000) GS:ffff889f87c00000(0000) knlGS:0000000000000000 [ 415.485350] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 415.491767] CR2: 0000000000000008 CR3: 0000000161d46003 CR4: 0000000000770ef0 [ 415.499738] PKRU: 55555554 [ 415.502750] Call Trace: [ 415.505482] <TASK> [ 415.507825] amdgpu_vm_update_range+0x32a/0x880 [amdgpu] [ 415.513869] amdgpu_vm_clear_freed+0x117/0x250 [amdgpu] [ 415.519814] amdgpu_amdkfd_gpuvm_unmap_memory_from_gpu+0x18c/0x250 [amdgpu] [ 415.527729] kfd_ioctl_unmap_memory_from_gpu+0xed/0x340 [amdgpu] [ 415.534551] kfd_ioctl+0x3b6/0x510 [amdgpu] V9: Addressed review comments from Christian - No NULL check reqd for root PT freeing - Free PT list regardless of needs_flush - Move adding BOs in list in a separate function V10: Added Christian's RB V11: squash in list fix Cc: Christian König <Christian.Koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Felix Kuehling <felix.kuehling@amd.com> Cc: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Acked-by: Felix Kuehling <felix.kuehling@amd.com> Acked-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Reviewed-by: Christian König <Christian.Koenig@amd.com> Tested-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Signed-off-by: Shashank Sharma <shashank.sharma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Nicholas Kazlauskas authored
[Why] Cursor update can be pre-empted by a request for setting target flip submission. This causes an issue where we're in the middle of the exit sequence trying to log to DM, but the pre-emption starts another DMCUB command submission that requires being out of idle. The DC lock aqusition can fail, and depending on the DM/OS interface it's possible that the function inserted into this thread must not fail. This means that lock aqusition must be skipped and exit *must* occur. [How] Modify when we consider idle as active. Consider it exited only once the exit has fully finished. Consider it as entered prior to actual notification. Since we're on the same core/thread the cached values are coherent and we'll see that we still need to exit. Once the cursor update resumes it'll continue doing the double exit but this won't cause a functional issue, just a (potential) redundant operation.

Christian Koenig authored
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 <christian.koenig@amd.com> Cc: Felix Kuehling <Felix.Kuehling@amd.com> Cc: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Acked-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Tested-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Reviewed-by: Shashank Sharma <shashank.sharma@amd.com> Reviewed-by: Christian Koenig <christian.koenig@amd.com> Signed-off-by: Christian Koenig <christian.koenig@amd.com> Signed-off-by: Shashank Sharma <shashank.sharma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
