Subject: [PATCH] drm/amdgpu: Fix last_update fence leak in amdgpu_vm_init()
amdgpu_vm_init() initializes vm->last_update, vm->last_unlocked and vm->last_tlb_flush with references to the stub fence taken via dma_fence_get_stub(). The error label at the end of the function releases the last_unlocked and last_tlb_flush references with dma_fence_put(), but the reference stored in vm->last_update is never dropped, so whenever the page table root creation, the reservation of the root BO or the PASID registration fails, the stub fence reference leaks.
Drop the vm->last_update reference together with the other stub fence references on the error path.
Fixes 187916e6ed9d ("drm/amdgpu: install stub fence into potential unused fence pointers")

From: Christian König <[email protected]>
[ Upstream commit e997b82745a5b2419bc5b72735811d7162ac994a ]
Store the 64bit sequence directly. Makes it simpler to use and saves a bit of fence reference counting overhead.

From: Christian König <[email protected]>
[ Upstream commit 5255e146c99a677d4d55fdb988544bd20c539a0b ]
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.

[ Upstream commit b4f7b4459b1b155e4c4977a6482b5df2cf08758c ]
amdgpu_vm_init() initializes vm->last_update, vm->last_unlocked and vm->last_tlb_flush with references to the stub fence taken via dma_fence_get_stub(). The error label at the end of the function releases the last_unlocked and last_tlb_flush references with dma_fence_put(), but the reference stored in vm->last_update is never dropped, so whenever the page table root creation, the reservation of the root BO or the PASID registration fails, the stub fence reference leaks.
