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/amdgpu: Add xcc param to SRIOV kiq write and WREG32_SOC15_IP_NO_KIQ (v4)

2023-11-09T22:01:10Z

WREG32/RREG32_SOC15_IP_NO_KIQ and amdgpu_virt_kiq_reg_write_reg_wait are not using the correct rlcg interface or mec engine, respectively. Add xcc instance parameter to them. v4: Use GET_INST and squash commit with: "drm/amdgpu: Add xcc_inst param to amdgpu_virt_kiq_reg_write_reg_wait" v3: xcc not needed for MMMHUB v2: rebase Signed-off-by: Victor Lu Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd: Disable XNACK on SRIOV environment

2023-11-07T16:15:37Z

The purpose of this patch is to disable XNACK or set XNACK OFF mode on SRIOV platform which doesn't support it. This will prevent user-space application to fail or result into unexpected behaviour whenever the application need to run test-case in XNACK ON mode.

drm/amdgpu: load sdma ucode in the guest machine

2023-07-25T17:47:26Z

[why] User mode driver need to check the sdma ucode version to see whether the sdma engine supports a new type of PM4 packet. In SRIOV, sdma is loaded by the host. And, there is no way to check the sdma ucode version of CHIP_NAVI12 and CHIP_SIENNA_CICHLID of the host in the guest machine. [how] Load the sdma ucode for CHIP_NAVI12 and CHIP_SIENNA_CICHLID in the guest machine. Signed-off-by: YuanShang Reviewed-By: Horace Chen Signed-off-by: Alex Deucher

drm/amdgpu: set sw state to gfxoff after SR-IOV reset

2023-07-25T17:35:23Z

[Why] Current SR-IOV will not set GC to off state, while it is a real GC hard reset. Whthout GFX off flag, driver may do gfxhub invalidation before firmware load and gfxhub gart enable. This operation may cause CP to become busy because GC is not in the right state for invalidation. [How] Add a function for SR-IOV to clean up some sw state before recover. Set adev->gfx.is_poweron to false to prevent gfxhub invalidation before gfx firmware autoload complete. Signed-off-by: Horace Chen Reviewed-by: HaiJun Chang Signed-off-by: Alex Deucher
