This patch adds interface to init power function for smu. It's to create smu_power_context structure, and allocate smu_dpm_context and context size to fill the smu_power_context data.
v2: add detailed info to describe this function Signed-off-by: Huang Rui <[email protected]> --- drivers/gpu/drm/amd/powerplay/amdgpu_smu.c | 10 ++++++++++ drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h | 3 +++ 2 files changed, 13 insertions(+) diff --git a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c index 71da3dc..10316a2 100644 --- a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c @@ -85,6 +85,16 @@ static int smu_smc_table_sw_init(struct smu_context *smu) return ret; } + /** + * Create smu_power_context structure, and allocate smu_dpm_context and + * context size to fill the smu_power_context data. + */ + ret = smu_init_power(smu); + if (ret) { + pr_err("Failed to init smu_init_power!\n"); + 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 8ca9835..d6cb895 100644 --- a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h +++ b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h @@ -36,6 +36,7 @@ struct smu_funcs { int (*init_microcode)(struct smu_context *smu); int (*init_smc_tables)(struct smu_context *smu); + int (*init_power)(struct smu_context *smu); int (*load_microcode)(struct smu_context *smu); int (*check_fw_status)(struct smu_context *smu); int (*read_pptable_from_vbios)(struct smu_context *smu); @@ -45,6 +46,8 @@ struct smu_funcs ((smu)->funcs->init_microcode ?
