The listed memory blocks correspond to the memory block representation +in sysfs. The command also shows the memory block size and the amount of memory +in online and offline state. +.sp +By default \fBlsmem\fP prints a human readable output table with the RANGE, +SIZE, STATE, REMOVABLE, and BLOCK columns. +.sp +Use the \fB--extended\fP or \fB--parse\fP option to customize the output +table. You can change the table format and limit, extend, or rearrange the +table columns. +.sp +Not all columns are supported on all systems. If an unsupported column is +specified, \fBlsmem\fP prints the column but does not provide any data for it. + +.SS COLUMNS +.TP +.B RANGE +Start and end address of the memory range. +.TP +.B SIZE +Size of the memory range. +.TP +.B STATE +Indication of the online status of the memory range. State "on->off" means +that the address range is in transition from online to offline. +.TP +.B REMOVABLE +"yes" if the memory range can be set offline, "no" if it cannot be set offline. +A dash ("\-") means that the range is already offline. +.TP +.B BLOCK +Memory block number or numbers that correspond to the memory range. +.TP +.B NODE +Numa node of memory. +.SH OPTIONS +.TP +.BR \-a ", " \-\-all +List each individual memory block, instead of combining memory blocks with +similar attributes. +.TP +.BR \-e , " \-\-extended" [=\fIlist\fP] +Display extended memory information in human-readable format. + +If the \fIlist\fP argument is omitted, all columns for which data is available +are included in the command output. + +The \fIlist\fP argument is a comma-separated list of column labels that specifies +the columns to be included in the output table and their sequence in the +table.
