This patch adds interface to set min dcef deep sleep for smu. It's to set min deep sleep dce fclk with bootup value from vbios via SetMinDeepSleepDcefclk MSG. v2: add detailed info to describe this function Signed-off-by: Huang Rui <ray.huang@xxxxxxx> --- drivers/gpu/drm/amd/powerplay/amdgpu_smu.c | 8 ++++++++ drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h | 3 +++ 2 files changed, 11 insertions(+) diff --git a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c index 747b6b7..5e22b15 100644 --- a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c @@ -200,6 +200,14 @@ static int smu_smc_table_hw_init(struct smu_context *smu) if (ret) return ret; + /* + * Set min deep sleep dce fclk with bootup value from vbios via + * SetMinDeepSleepDcefclk MSG. + */ + ret = smu_set_min_dcef_deep_sleep(smu); + if (ret) + return ret; + return 0; } diff --git a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h index e7e9fec..90e80cd 100644 --- a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h +++ b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h @@ -46,6 +46,7 @@ struct smu_funcs int (*populate_smc_pptable)(struct smu_context *smu); int (*check_fw_version)(struct smu_context *smu); int (*write_pptable)(struct smu_context *smu); + int (*set_min_dcef_deep_sleep)(struct smu_context *smu); }; #define smu_init_microcode(smu) \ @@ -72,6 +73,8 @@ struct smu_funcs ((smu)->funcs->check_fw_version ?
