This patch adds interface to parse pptable for smu. It's to parse pptable format and fill PPTable_t smc_pptable to smu_table_context structure. And read the smc_dpm_table from vbios, then fill it into smc_pptable. v2: add detailed info to describe this function Signed-off-by: Huang Rui <ray.huang@xxxxxxx> --- drivers/gpu/drm/amd/powerplay/amdgpu_smu.c | 9 +++++++++ drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h | 4 ++++ 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 931343c..323db7d 100644 --- a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c @@ -166,6 +166,15 @@ static int smu_smc_table_hw_init(struct smu_context *smu) if (ret) return ret; + /* + * Parse pptable format and fill PPTable_t smc_pptable to + * smu_table_context structure.
