This patch adds interface to check fw version for smu. It's to send msg GetDriverIfVersion to check if the return value is equal with DRIVER_IF_VERSION of smc header. 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 b40a3c1..5196825 100644 --- a/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/powerplay/amdgpu_smu.c @@ -184,6 +184,14 @@ static int smu_smc_table_hw_init(struct smu_context *smu) if (ret) return ret; + /* + * Send msg GetDriverIfVersion to check if the return value is equal + * with DRIVER_IF_VERSION of smc header. + */ + ret = smu_check_fw_version(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 da79777..9525265 100644 --- a/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h +++ b/drivers/gpu/drm/amd/powerplay/inc/amdgpu_smu.h @@ -44,6 +44,7 @@ struct smu_funcs int (*check_pptable)(struct smu_context *smu); int (*parse_pptable)(struct smu_context *smu); int (*populate_smc_pptable)(struct smu_context *smu); + int (*check_fw_version)(struct smu_context *smu); }; #define smu_init_microcode(smu) \ @@ -66,6 +67,8 @@ struct smu_funcs ((smu)->funcs->parse_pptable ?
