It's to copy pptable bo in the vram to smc with SMU MSGs such as SetDriverDramAddr and TransferTableDram2Smu. v2: add detailed info to describe this function Signed-off-by: Huang Rui Acked-by: Alex Deucher Signed-off-by: Alex Deucher --- 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 519682541cae..747b6b7a7675 100644 --- a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c @@ -192,6 +192,14 @@ static int smu_smc_table_hw_init(struct smu_context *smu) if (ret) return ret; + /* + * Copy pptable bo in the vram to smc with SMU MSGs such as + * SetDriverDramAddr and TransferTableDram2Smu. + */ + ret = smu_write_pptable(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 95252653a665..e7e9fecbb086 100644 --- a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h +++ b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h @@ -45,6 +45,7 @@ struct smu_funcs int (*parse_pptable)(struct smu_context *smu); int (*populate_smc_pptable)(struct smu_context *smu); int (*check_fw_version)(struct smu_context *smu); + int (*write_pptable)(struct smu_context *smu); }; #define smu_init_microcode(smu) \ @@ -69,6 +70,8 @@ struct smu_funcs ((smu)->funcs->populate_smc_pptable ?
