-On Turing, LS PMU RTOS is bootstrapped by SEC2 RTOS, so PMU needs some time to boot & get ready to process request as boot happened bit late in flow. -So issue here is, code execution reaches function gk20a_init_pstate_pmu_support() to send boardobj commands to PMU before PMU ready to accept. -As a result, this cause command request failure as PMU is not ready yet due to falcon clock is slower compared CPU clock. -To fix issue, waiting for pmu_ready flag to become true before staring PSTATE requests to PMU. -pmu_ready flag will be set to true as soon as INIT message received from PMU RTOS. -Pre Turing-PMU RTOS will be ready much ahead of reaching this point.
