2021-05-19drm/amdgpu: Handle IOMMU enabled case.Andrey Grodzovsky1-4/+0
Problem: Handle all DMA IOMMU group related dependencies before the group is removed. Those manifest themself in that when IOMMU enabled DMA map/unmap is dependent on the presence of IOMMU group the device belongs to but, this group is released once the device is removed from PCI topology. Fix: Expedite all such unmap operations to pci remove driver callback. v5: Drop IOMMU notifier and switch to lockless call to ttm_tt_unpopulate v6: Drop the BO unamp list v7: Drop amdgpu_gart_fini In amdgpu_ih_ring_fini do uncinditional check (!ih->ring) to avoid freeing uniniitalized rings. Call amdgpu_ih_ring_fini unconditionally. v8: Add deatiled explanation Signed-off-by: Andrey Grodzovsky <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2021-05-19drm/amdgpu: Split amdgpu_device_fini into early and lateAndrey Grodzovsky1-1/+1
Some of the stuff in amdgpu_device_fini such as HW interrupts disable and pending fences finilization must be done right away on pci_remove while most of the stuff which relates to finilizing and releasing driver data structures can be kept until drm_driver.release hook is called, i.e. when the last device reference is dropped. v4: Change functions prefix early->hw and late->sw Signed-off-by: Andrey Grodzovsky <[email protected]> Acked-by: Christian König <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2021-04-09drm/amdgpu: ih reroute for newer asics than vega20Alex Sierra1-3/+3
Starting Arcturus, it supports ih reroute through mmio directly in bare metal environment. This is also valid for newer asics such as Aldebaran.

2021-03-23drm/amdgpu: enable retry fault wptr overflowPhilip Yang1-21/+11
If xnack is on, VM retry fault interrupt send to IH ring1, and ring1 will be full quickly. IH cannot receive other interrupts, this causes deadlock if migrating buffer using sdma and waiting for sdma done while handling retry fault. Remove VMC from IH storm client, enable ring1 write pointer overflow, then IH will drop retry fault interrupts and be able to receive other interrupts while driver is handling retry fault. IH ring1 write pointer doesn't writeback to memory by IH, and ring1 write pointer recorded by self-irq is not updated, so always read the latest ring1 write pointer from register.

2021-03-23drm/amdgpu: correct IH_CHICKEN programming for aldebaranHawking Zhang1-0/+15
For aldebaran, psp firmware won't program IH_CHICKEN. it now depends on driver to program it properly so either bus address or gpu virtual address is just working for ih ring.
