If you look at vega20_send_msg_to_smc_with_parameter:=20
static int vega20_send_msg_to_smc_with_parameter(struct pp_hwmgr *hwmgr,
uint16_t msg, uint32_t parameter)
{
struct amdgpu_device *adev =3D hwmgr->adev;
int ret =3D 0;
vega20_wait_for_response(hwmgr);
WREG32_SOC15(MP1, 0, mmMP1_SMN_C2PMSG_90, 0);
WREG32_SOC15(MP1, 0, mmMP1_SMN_C2PMSG_82, parameter);
vega20_send_msg_to_smc_without_waiting(hwmgr, msg);
ret =3D vega20_wait_for_response(hwmgr);
if (ret !=3D PPSMC_Result_OK)
pr_err("Failed to send message 0x%x, response 0x%x\n&q=
uot;, msg,
ret);
return (ret =3D=3D PPSMC_Result_OK) ? 0 : -EIO;
}
It returns 0 on success and -EIO on failure, which is then in turn returned
from vega20_set_fclk_to_highest_dpm_leve. Where did you see the check/retry=
on
EINVAL? Perhaps -EIO should be -EINVAL?
