From a7f28103374787ae43b936cd2ec2f8388958668e Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Wed, 29 Apr 2020 18:49:23 +0800 Subject: drm/amdgpu: add amdgpu_virt_get_vf_mode helper function the swsmu or powerplay(hwmgr) need to handle task according to different VF mode, this function to help query vf mode. vf mode: 1. SRIOV_VF_MODE_BARE_METAL: the driver work on host OS (PF) 2. SRIOV_VF_MODE_ONE_VF : the driver work on guest OS with one VF 3. SRIOV_VF_MODE_MULTI_VF : the driver work on guest OS with multi VF Signed-off-by: Kevin Wang Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h index de27308802c9..b90e822cebd7 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_virt.h @@ -35,6 +35,12 @@ /* tonga/fiji use this offset */ #define mmBIF_IOV_FUNC_IDENTIFIER 0x1503 +enum amdgpu_sriov_vf_mode { + SRIOV_VF_MODE_BARE_METAL = 0, + SRIOV_VF_MODE_ONE_VF, + SRIOV_VF_MODE_MULTI_VF, +}; + struct amdgpu_mm_table { struct amdgpu_bo *bo; uint32_t *cpu_addr; @@ -323,4 +329,6 @@ void amdgpu_detect_virtualization(struct amdgpu_device *adev); bool amdgpu_virt_can_access_debugfs(struct amdgpu_device *adev); int amdgpu_virt_enable_access_debugfs(struct amdgpu_device *adev); void amdgpu_virt_disable_access_debugfs(struct amdgpu_device *adev); + +enum amdgpu_sriov_vf_mode amdgpu_virt_get_sriov_vf_mode(struct amdgpu_device *adev); #endif -- cgit v1.2.3
