2023-07-12drm/amdgpu: Increase soft IH ring sizePhilip Yang
Retry faults are delegated to soft IH ring and then processed by deferred worker. Current soft IH ring size PAGE_SIZE can store 128 entries, which may overflow and drop retry faults, causes HW stucks because the retry fault is not recovered. Increase soft IH ring size to 8KB, enough to store 256 CAM entries because we clear the CAM entry after handling the retry fault from soft ring. Define macro IH_RING_SIZE and IH_SW_RING_SIZE to remove duplicate constant. Show warning message if soft IH ring overflows with CAM enabled because this should not happen.

2022-09-14drm/amdgpu: move nbio ih_doorbell_range() into ih code for vegaAlex Deucher
This mirrors what we do for other asics and this way we are sure the ih doorbell range is properly initialized. There is a comment about the way doorbells on gfx9 work that requires that they are initialized for other IPs before GFX is initialized. In this case IH is initialized before GFX, so there should be no issue. This is a prerequisite for fixing the Unsupported Request error reported through AER during driver load. Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373 The error was unnoticed before and got visible because of the commit referenced below. This doesn't fix anything in the commit below, rather fixes the issue in amdgpu exposed by the commit. The reference is only to associate this commit with below one so that both go together.

2021-12-01drm/amdgpu: handle IH ring1 overflowPhilip Yang
IH ring1 is used to process GPU retry fault, overflow is enabled to drain retry fault because we want receive other interrupts while handling retry fault to recover range. There is no overflow flag set when wptr pass rptr. Use timestamp of rptr and wptr to handle overflow and drain retry fault. If fault timestamp goes backward, the fault is filtered and should not be processed. Drain fault is finished if processed_timestamp is equal to or larger than checkpoint timestamp. Add amdgpu_ih_functions interface decode_iv_ts for different chips to get timestamp from IV entry with different iv size and timestamp offset. amdgpu_ih_decode_iv_ts_helper is used for vega10, vega20, navi10.

Problem: Handle all DMA IOMMU group related dependencies before the group is removed.

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.

2019-01-14drm/amdgpu: fix IH overflow on Vega10 v2Christian König
When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler.
