Members
mp Maximum Power indicates the sustained maximum power consumed by the NVM subsystem in this
power state. The power in Watts is equal to the value in this field multiplied by the scale
specified in the Max Power Scale bit (see enum nvme_psd_flags). A value of 0 indicates
Maximum Power is not reported.
rsvd2 Reserved
flags Additional decoding flags, see enum nvme_psd_flags.
enlat Entry Latency indicates the maximum latency in microseconds associated with entering this
power state. A value of 0 indicates Entry Latency is not reported.
exlat Exit Latency indicates the maximum latency in microseconds associated with exiting this power
state. A value of 0 indicates Exit Latency is not reported.
rrt Relative Read Throughput indicates the read throughput rank associated with this power state
relative to others. The value in this is less than the number of supported power states.
rrl Relative Read Latency indicates the read latency rank associated with this power state
relative to others. The value in this field is less than the number of supported power
states.
rwt Relative Write Throughput indicates write throughput rank associated with this power state
relative to others. The value in this field is less than the number of supported power states
rwl Relative Write Latency indicates the write latency rank associated with this power state
relative to others. The value in this field is less than the number of supported power states
idlp Idle Power indicates the typical power consumed by the NVM subsystem over 30 seconds in this
power state when idle.
ips Idle Power Scale indicates the scale for struct nvme_id_psd.idlp, see enum nvme_psd_ps for
decoding this field.
rsvd19 Reserved
actp Active Power indicates the largest average power consumed by the NVM subsystem over a 10
second period in this power state with the workload indicated in the Active Power Workload
field.
apws Bits 7-6: Active Power Scale(APS) indicates the scale for the struct nvme_id_psd.actp, see
enum nvme_psd_ps for decoding this value. Bits 2-0: Active Power Workload(APW) indicates the
workload used to calculate maximum power for this power state. See enum nvme_psd_workload
for decoding this field.
rsvd23 Reserved
