drm/amdgpu: add a module parameter to control the AGP aperture

2023-11-17T05:58:20Z

Add a module parameter to control the AGP aperture. The AGP aperture is an aperture in the GPU's internal address space which provides direct non-paged access to the platform address space. This access is non-snooped so only uncached memory can be accessed. Add a knob so that we can toggle this for debugging.

drm/amdgpu: Use correct KIQ MEC engine for gfx9.4.3 (v5)

2023-11-09T22:03:07Z

amdgpu_kiq_wreg/rreg is hardcoded to use MEC engine 0. Add an xcc_id parameter to amdgpu_kiq_wreg/rreg, define W/RREG32_XCC and amdgpu_device_xcc_wreg/rreg to use the new xcc_id parameter. Using amdgpu_sriov_runtime to determine whether to access via kiq or RLC is sufficient for now. v5: add condition in amdgpu_device_xcc_w/rreg, remove trace func call v4: avoid using amdgpu_sriov_w/rreg v3: use W/RREG32_XCC to handle non-kiq case v2: define amdgpu_device_xcc_wreg/rreg instead of changing parameters of amdgpu_device_wreg/rreg Signed-off-by: Victor Lu Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd: Explicitly disable ASPM when dynamic switching disabled

2023-10-26T22:41:23Z

Currently there are separate but related checks: * amdgpu_device_should_use_aspm() * amdgpu_device_aspm_support_quirk() * amdgpu_device_pcie_dynamic_switching_supported() Simplify into checking whether DPM was enabled or not in the auto case. This works because amdgpu_device_pcie_dynamic_switching_supported() populates that value. Signed-off-by: Mario Limonciello Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd: Evict resources during PM ops prepare() callback

2023-10-13T15:00:18Z

Linux PM core has a prepare() callback run before suspend. If the system is under high memory pressure, the resources may need to be evicted into swap instead. If the storage backing for swap is offlined during the suspend() step then such a call may fail. So move this step into prepare() to move evict majority of resources and update all non-pmops callers to call the same callback.
