Flags indicating the optional Device Self-test command or operation behaviors supported by the controller or NVM subsystem.

## NAME

enum nvme\_id\_ctrl\_dsto - Flags indicating the optional Device Self-test command or operation behaviors supported by the controller or NVM subsystem.

## SYNOPSIS

enum nvme\_id\_ctrl\_dsto {\
     **NVME\_CTRL\_DSTO\_SDSO\_SHIFT** , \
\
     **NVME\_CTRL\_DSTO\_HIRS\_SHIFT** , \
\
     **NVME\_CTRL\_DSTO\_SDSO\_MASK** , \
\
     **NVME\_CTRL\_DSTO\_HIRS\_MASK** , \

};

## Constants

- NVME\_CTRL\_DSTO\_SDSO\_SHIFT

  Shift amount to get the value of Single Device Self-test Operation from Device Self-test Options field.

- NVME\_CTRL\_DSTO\_HIRS\_SHIFT

  Shift amount to get the value of  Host-Initiated Refresh Support from Device Self-test Options field.

- NVME\_CTRL\_DSTO\_SDSO\_MASK

  Mask to get the value of Single Device Self-test Operation

- NVME\_CTRL\_DSTO\_HIRS\_MASK

  Mask to get the value of Host-Initiated Refresh Support

- NVME\_CTRL\_DSTO\_ONE\_DST

  If set, then the NVM subsystem supports only one device self-test operation in progress at a time. If cleared, then the NVM subsystem supports one device self-test operation per controller at a time.

- NVME\_CTRL\_DSTO\_HIRS

  If set, then the controller supports the Host-Initiated Refresh capability.
