Add support to configure and retrieve ppt1 limit for smu_v13_0_12 v2: Add update_caps function and update ppt1 cap based on max ppt1 value, optimize the return values (Lijo)
v3: Add Null ptr check, return not supported in case of invalid level/type (Lijo) Signed-off-by: Asad Kamal <[email protected]> Reviewed-by: Lijo Lazar <[email protected]> --- drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h | 4 +- .../drm/amd/pm/swsmu/smu13/smu_v13_0_12_ppt.c | 8 ++ .../drm/amd/pm/swsmu/smu13/smu_v13_0_6_ppt.c | 80 ++++++++++++++++++- .../drm/amd/pm/swsmu/smu13/smu_v13_0_6_ppt.h | 4 + 4 files changed, 92 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h b/drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h index 3a3930ef7ed9..9b71a8afdd35 100644 --- a/drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h +++ b/drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h @@ -286,7 +286,9 @@ __SMU_DUMMY_MAP(SetTimestamp), \ __SMU_DUMMY_MAP(GetTimestamp), \ __SMU_DUMMY_MAP(GetBadPageIpid), \ - __SMU_DUMMY_MAP(EraseRasTable), + __SMU_DUMMY_MAP(EraseRasTable), \ + __SMU_DUMMY_MAP(SetFastPptLimit), \ + __SMU_DUMMY_MAP(GetFastPptLimit), #undef __SMU_DUMMY_MAP #define __SMU_DUMMY_MAP(type) SMU_MSG_##type diff --git a/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_12_ppt.c b/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_12_ppt.c index 0ce8cff27bf9..c513cbeb361f 100644 --- a/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_12_ppt.c +++ b/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_12_ppt.c @@ -148,6 +148,8 @@ const struct cmn2asic_msg_mapping smu_v13_0_12_message_map[SMU_MSG_MAX_COUNT] = MSG_MAP(GetTimestamp, PPSMC_MSG_GetTimestamp, 0), MSG_MAP(GetBadPageIpid, PPSMC_MSG_GetBadPageIpIdLoHi, 0), MSG_MAP(EraseRasTable, PPSMC_MSG_EraseRasTable, 0), + MSG_MAP(SetFastPptLimit, PPSMC_MSG_SetFastPptLimit, 1), + MSG_MAP(GetFastPptLimit, PPSMC_MSG_GetFastPptLimit, 1), };
