Structure is not parsed by + program. This overrides the vendor specific and human readable options. + +-v:: +--vendor-specific:: + In addition to parsing known fields, this option will dump + the vendor specific region of the structure in hex with ascii + interpretation. + +-H:: +--human-readable:: + This option will parse and format many of the bit fields + into human-readable formats. + +-o :: +--output-format=:: + Set the reporting format to 'normal', 'json', or + 'binary'. Only one output format can be used at a time. + +EXAMPLES +-------- +* Has the program interpret the returned buffer and display the known +fields in a human readable format: ++ +------------ +# nvme huawei id-ctrl /dev/nvme0 +------------ + +NVME +---- +Part of the nvme-user suite -- cgit v1.2.3
