drm/amdgpu: Merge get_reserved_allocation to get_vbios_allocations.

2022-03-15T19:01:12+00:00

Some ASICs need reserved memory for firmware or other components, which is not allowed to be used by driver. amdgpu_gmc_get_reserved_allocation is to handle additional areas. To avoid any missing calling, merged amdgpu_gmc_get_reserved_allocation to amdgpu_gmc_get_vbios_allocations.

drm/amdgpu: handle IH ring1 overflow

2021-12-01T21:03:34+00:00

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.
