From b92c628712ed3a1cf5d4a144290e8ffc170bf51e Mon Sep 17 00:00:00 2001 From: Rex Zhu Date: Tue, 5 Jun 2018 13:06:11 +0800 Subject: [PATCH] drm/amd/pp: Unify powergate_uvd/vce/mmhub to set_powergating_by_smu Some HW ip blocks need call SMU to enter/leave power gate state. So export common set_powergating_by_smu interface. 1. keep consistent with set_clockgating_by_smu 2. scales easily to powergate other ip(gfx) if necessary Reviewed-by: Evan Quan Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_dpm.h | 14 +++------ drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c | 8 ++--- drivers/gpu/drm/amd/amdgpu/ci_dpm.c | 15 +++++++++- drivers/gpu/drm/amd/amdgpu/kv_dpm.c | 15 +++++++++- drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c | 4 +-- .../gpu/drm/amd/include/kgd_pp_interface.h | 5 ++-- drivers/gpu/drm/amd/powerplay/amd_powerplay.c | 29 +++++++++++++++++-- 7 files changed, 66 insertions(+), 24 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_dpm.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_dpm.h index c6d692625687..ff24e1cc5b65 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_dpm.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_dpm.h @@ -287,12 +287,6 @@ enum amdgpu_pcie_gen { #define amdgpu_dpm_force_performance_level(adev, l) \ ((adev)->powerplay.pp_funcs->force_performance_level((adev)->powerplay.pp_handle, (l))) -#define amdgpu_dpm_powergate_uvd(adev, g) \ - ((adev)->powerplay.pp_funcs->powergate_uvd((adev)->powerplay.pp_handle, (g))) - -#define amdgpu_dpm_powergate_vce(adev, g) \ - ((adev)->powerplay.pp_funcs->powergate_vce((adev)->powerplay.pp_handle, (g))) - #define amdgpu_dpm_get_current_power_state(adev) \ ((adev)->powerplay.pp_funcs->get_current_power_state((adev)->powerplay.pp_handle)) @@ -347,6 +341,10 @@ enum amdgpu_pcie_gen { ((adev)->powerplay.pp_funcs->set_clockgating_by_smu(\ (adev)->powerplay.pp_handle, msg_id)) +#define amdgpu_dpm_set_powergating_by_smu(adev, block_type, gate) \ + ((adev)->powerplay.pp_funcs->set_powergating_by_smu(\ + (adev)->powerplay.pp_handle, block_type, gate)) + #define amdgpu_dpm_get_power_profile_mode(adev, buf) \ ((adev)->powerplay.pp_funcs->get_power_profile_mode(\ (adev)->powerplay.pp_handle, buf)) @@ -359,10 +357,6 @@ enum amdgpu_pcie_gen { ((adev)->powerplay.pp_funcs->odn_edit_dpm_table(\ (adev)->powerplay.pp_handle, type, parameter, size)) -#define amdgpu_dpm_powergate_mmhub(adev) \ - ((adev)->powerplay.pp_funcs->powergate_mmhub( \ - (adev)->powerplay.pp_handle)) - struct amdgpu_dpm { struct amdgpu_ps *ps;
