From 4b5ece24ce564176f8ad786ad02b681a373bc615 Mon Sep 17 00:00:00 2001 From: Eric Huang Date: Tue, 19 Jan 2016 14:28:56 -0500 Subject: [PATCH] drm/amd/amdgpu: Improve amdgpu_dpm* macros to avoid unexpected result (v2) The two macros returns are values which probably are used in the expression of calculation. Without the brackets the result of the expression may be wrong. v2: agd: squash both patches together Reviewed-by: Alex Deucher Signed-off-by: Eric Huang --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 44 ++++++++++++++--------------- 1 file changed, 22 insertions(+), 22 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 313b0cc8d676..82edf95b7740 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -2278,60 +2278,60 @@ amdgpu_get_sdma_instance(struct amdgpu_ring *ring) #define amdgpu_dpm_enable_bapm(adev, e) (adev)->pm.funcs->enable_bapm((adev), (e)) #define amdgpu_dpm_get_temperature(adev) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->get_temperature((adev)->powerplay.pp_handle) : \ - (adev)->pm.funcs->get_temperature((adev)) + (adev)->pm.funcs->get_temperature((adev))) #define amdgpu_dpm_set_fan_control_mode(adev, m) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->set_fan_control_mode((adev)->powerplay.pp_handle, (m)) : \ - (adev)->pm.funcs->set_fan_control_mode((adev), (m)) + (adev)->pm.funcs->set_fan_control_mode((adev), (m))) #define amdgpu_dpm_get_fan_control_mode(adev) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->get_fan_control_mode((adev)->powerplay.pp_handle) : \ - (adev)->pm.funcs->get_fan_control_mode((adev)) + (adev)->pm.funcs->get_fan_control_mode((adev))) #define amdgpu_dpm_set_fan_speed_percent(adev, s) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->set_fan_speed_percent((adev)->powerplay.pp_handle, (s)) : \ - (adev)->pm.funcs->set_fan_speed_percent((adev), (s)) + (adev)->pm.funcs->set_fan_speed_percent((adev), (s))) #define amdgpu_dpm_get_fan_speed_percent(adev, s) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->get_fan_speed_percent((adev)->powerplay.pp_handle, (s)) : \ - (adev)->pm.funcs->get_fan_speed_percent((adev), (s)) + (adev)->pm.funcs->get_fan_speed_percent((adev), (s))) #define amdgpu_dpm_get_sclk(adev, l) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->get_sclk((adev)->powerplay.pp_handle, (l)) : \ - (adev)->pm.funcs->get_sclk((adev), (l)) + (adev)->pm.funcs->get_sclk((adev), (l))) #define amdgpu_dpm_get_mclk(adev, l) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->get_mclk((adev)->powerplay.pp_handle, (l)) : \ - (adev)->pm.funcs->get_mclk((adev), (l)) + (adev)->pm.funcs->get_mclk((adev), (l))) #define amdgpu_dpm_force_performance_level(adev, l) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->force_performance_level((adev)->powerplay.pp_handle, (l)) : \ - (adev)->pm.funcs->force_performance_level((adev), (l)) + (adev)->pm.funcs->force_performance_level((adev), (l))) #define amdgpu_dpm_powergate_uvd(adev, g) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->powergate_uvd((adev)->powerplay.pp_handle, (g)) : \ - (adev)->pm.funcs->powergate_uvd((adev), (g)) + (adev)->pm.funcs->powergate_uvd((adev), (g))) #define amdgpu_dpm_powergate_vce(adev, g) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->powergate_vce((adev)->powerplay.pp_handle, (g)) : \ - (adev)->pm.funcs->powergate_vce((adev), (g)) + (adev)->pm.funcs->powergate_vce((adev), (g))) #define amdgpu_dpm_debugfs_print_current_performance_level(adev, m) \ - (adev)->pp_enabled ? \ + ((adev)->pp_enabled ? \ (adev)->powerplay.pp_funcs->print_current_performance_level((adev)->powerplay.pp_handle, (m)) : \ - (adev)->pm.funcs->debugfs_print_current_performance_level((adev), (m)) + (adev)->pm.funcs->debugfs_print_current_performance_level((adev), (m))) #define amdgpu_dpm_get_current_power_state(adev) \ (adev)->powerplay.pp_funcs->get_current_power_state((adev)->powerplay.pp_handle) -- 2.20.1
