[AMD Public Use] Hi @Zhang, Hawking
I tried to hide mp0/mp1 mode1 reset under AMD_RESET_METHOD_MODE1, while it seems that we need to tackle the difference in function amdgpu_device_gpu_recover, like following change in 3rd patch: @@ -4275,16 +4277,18 @@ int amdgpu_device_gpu_recover(struct amdgpu_device *adev, struct amdgpu_device *tmp_adev = NULL; int i, r = 0; bool in_ras_intr = amdgpu_ras_intr_triggered(); - bool use_baco = - (amdgpu_asic_reset_method(adev) == AMD_RESET_METHOD_BACO) ? - true : false; + bool is_full_reset = false; bool audio_suspended = false; + if ((amdgpu_asic_reset_method(adev) == AMD_RESET_METHOD_BACO) || + (amdgpu_asic_reset_method(adev) == AMD_RESET_METHOD_MODE1)) + is_full_reset = true; That's the reason I add new AMD_RESET_METHOD_PSP_MODE1.

The new mode 1 reset will be used starting from sienna_cichlid. It should be quite strait forward for us to either initialize a flag like is_smu_support_mode1 during sw_init or even check the asic_type in nv_asic_mode1_reset to decide whether we use psp_gpu_reset or smu_gpu_reset.etc. That's saying, we don't need to change the reset_method interface, where we decide whether we go to BACO/mode reset/pci config space reset.etc. We just differentiate the approach (i.e. psp or smu) in nv_asic_mode1_reset. Thoughts?
