Constants

NVME_SMART_CW_ASCBT_SHIFT
    Shift amount to get the available spare capacity has fallen below the threshold.

NVME_SMART_CW_TTC_SHIFT
    Shift amount to get the temperature is either greater than or equal to an over temperature threshold; or less than or equal to an under temperature threshold.

NVME_SMART_CW_NDR_SHIFT
    Shift amount to get the NVM subsystem reliability has been degraded due to significant media related errors or any internal error that degrades NVM subsystem reliability.

NVME_SMART_CW_AMRO_SHIFT
    Shift amount to get the all of the media has been placed in read only mode. The controller shall not set this bit if the read-only condition on the media is a result of a change in the write protection state of a namespace.

NVME_SMART_CW_VMBF_SHIFT
    Shift amount to get the volatile memory backup device has failed. This field is only valid if the controller has a volatile memory backup solution.

NVME_SMART_CW_PMRRO_SHIFT
    Shift amount to get the Persistent Memory Region has become read-only or unreliable.

NVME_SMART_CW_ASCBT_MASK
    If set, then the available spare capacity has fallen below the threshold.

NVME_SMART_CW_TTC_MASK
    Mask to get the temperature is either greater than or equal to an over temperature threshold; or less than or equal to an under temperature threshold.

NVME_SMART_CW_NDR_MASK
    Mask to get the NVM subsystem reliability has been degraded due to significant media related errors or any internal error that degrades NVM subsystem reliability.

NVME_SMART_CW_AMRO_MASK
    Mask to get the all of the media has been placed in read only mode. The controller shall not set this bit if the read-only condition on the media is a result of a change in the write protection state of a namespace.

NVME_SMART_CW_VMBF_MASK
    Mask to get the volatile memory backup device has failed. This field is only valid if the controller has a volatile memory backup solution.

NVME_SMART_CW_PMRRO_MASK
    Mask to get the Persistent Memory Region has become read-only or unreliable.

NVME_SMART_CRIT_SPARE
    If set, then the available spare capacity has fallen below the threshold.

NVME_SMART_CRIT_TEMPERATURE
    If set, then a temperature is either greater than or equal to an over temperature threshold; or less than or equal to an under temperature threshold.

NVME_SMART_CRIT_DEGRADED
    If set, then the NVM subsystem reliability has been degraded due to significant media related errors or any internal error that degrades NVM subsystem reliability.

NVME_SMART_CRIT_MEDIA
    If set, then all of the media has been placed in read only mode. The controller shall not set this bit if the read-only condition on the media is a result of a change in the write protection state of a namespace.

NVME_SMART_CRIT_VOLATILE_MEMORY
    If set, then the volatile memory backup device has failed. This field is only valid if the controller has a volatile memory backup solution.

NVME_SMART_CRIT_PMR_RO
    If set, then the Persistent Memory Region has become read-only or unreliable.
