xnvme_geo

Enums

xnvme_geo_type

enum xnvme_geo_type

Representation of the type of device / geo / namespace.

Values:

enumerator XNVME_GEO_UNKNOWN
enumerator XNVME_GEO_CONVENTIONAL
enumerator XNVME_GEO_ZONED

Structs

xnvme_geo

struct xnvme_geo

Representation of device “geometry”.

This will remain in some, encapsulating IO parameters such as MDTS, ZONE APPEND MDTS, nbytes, nsect etc. mapping to zone characteristics, as well as extended LBA formats.
