- During nvgpu_poweron, PERFMON_INIT RPC and ACR_INIT_WPR_REGION command is sent to PMU in two different threads. - For perfmon RPC method is used and for ACR, CMD-MSG queue is used. - Since the pmu thread and poweron thread run in parallel, the pmu sequence acquired by both can have the same seq_id. - For Perfmon RPC, nvgpu_pmu_seq_free_release() is called followed by nvgpu_pmu_seq_release(). - This causes clearing of sequence for the next command. - To resolve this, instead of nvgpu_pmu_seq_free_release(), just free the rpc-payload after getting ack for perfmon and then do sequence release. - This ensures that the ACR cmd sent just after perfmon RPC does not get the same seq_id and the sequence is not cleared.
