From 2c02b38a10fc0717fadd94aab2b7eee656a3c44a Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Fri, 20 Mar 2020 14:03:25 -0400 Subject: [PATCH] drm/amd/swSMU: add callback to set AC/DC power source (v2) This is needed to tell the SMU firmware what state is in in certain cases. DC mode does not allow overclocking for example. v2: split Evan's original patch (Alex) Bug: https://gitlab.freedesktop.org/drm/amd/issues/1043 Reviewed-by: Evan Quan Signed-off-by: Evan Quan Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h | 1 + drivers/gpu/drm/amd/powerplay/smu_internal.h | 3 +++ 2 files changed, 4 insertions(+) diff --git a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h index 657a6f17e91f..323e7e61493b 100644 --- a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h +++ b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h @@ -570,6 +570,7 @@ struct pptable_funcs { int (*override_pcie_parameters)(struct smu_context *smu); uint32_t (*get_pptable_power_limit)(struct smu_context *smu); int (*disable_umc_cdr_12gbps_workaround)(struct smu_context *smu); + int (*set_power_source)(struct smu_context *smu, enum smu_power_src_type power_src); }; int smu_load_microcode(struct smu_context *smu); diff --git a/drivers/gpu/drm/amd/powerplay/smu_internal.h b/drivers/gpu/drm/amd/powerplay/smu_internal.h index 6900877de845..40c35bcc5a0a 100644 --- a/drivers/gpu/drm/amd/powerplay/smu_internal.h +++ b/drivers/gpu/drm/amd/powerplay/smu_internal.h @@ -211,4 +211,7 @@ static inline int smu_send_smc_msg(struct smu_context *smu, enum smu_message_typ #define smu_disable_umc_cdr_12gbps_workaround(smu) \ ((smu)->ppt_funcs->disable_umc_cdr_12gbps_workaround ?
