From e178f10726d136e54080a43382b858020ea694a3 Mon Sep 17 00:00:00 2001 From: Kent Russell Date: Mon, 1 Apr 2019 07:19:06 -0400 Subject: [PATCH] drm/amdgpu: Allow switching to CUSTOM profile on Vega20 Vega20 stores a CUSTOM profile on the GPU, but it may not be valid. Add a bool to vega20_hwmgr to determine whether or not a valid CUSTOM profile has been set, and use that to check when a user requests switching to the CUSTOM profile without passing in any arguments. Then if the CUSTOM profile has been set already, we can switch to it without providing the parameters again Signed-off-by: Kent Russell Reviewed-by: Evan Quan Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.c | 16 +++++++++++++++- drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.h | 2 ++ 2 files changed, 17 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.c b/drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.c index 3f349ad..34f3782 100644 --- a/drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.c +++ b/drivers/gpu/drm/amd/powerplay/hwmgr/vega20_hwmgr.c @@ -427,6 +427,7 @@ static int vega20_hwmgr_backend_init(struct pp_hwmgr *hwmgr) hwmgr->platform_descriptor.clockStep.memoryClock = 500; data->total_active_cus = adev->gfx.cu_info.number; + data->is_custom_profile_set = false; return 0; } @@ -3827,7 +3828,11 @@ static int vega20_set_power_profile_mode(struct pp_hwmgr *hwmgr, long *input, ui } if (power_profile_mode == PP_SMC_POWER_PROFILE_CUSTOM) { - if (size < 10) + struct vega20_hwmgr *data = + (struct vega20_hwmgr *)(hwmgr->backend); + if (size == 0 && !data->is_custom_profile_set) + return -EINVAL; + if (size < 10 && size != 0) return -EINVAL; result = vega20_get_activity_monitor_coeff(hwmgr, @@ -3837,6 +3842,13 @@ static int vega20_set_power_profile_mode(struct pp_hwmgr *hwmgr, long *input, ui "[SetPowerProfile] Failed to get activity monitor!", return result); + /* If size==0, then we want to apply the already-configured + * CUSTOM profile again.
