s390 is able to provide memory topology information of the current CEC
via a new userspace-kernel interface. zmemtopo is a tool to convert the
raw data into human readable form.
Usage: zmemtopo [OPTIONS]
Display CEC memory topology of allocated memory increments.
OUTPUT FORMAT OPTIONS
-l, --level NESTING_LEVEL Set the topology display depth to NESTING_LEVEL
-f, --full Display tree view with padded elements
-r, --reverse Reverse tree view hierarchy direction
-t, --table Use table view to display topology
-s, --sort FIELD Sort view by field
(nr, lpar, size)
-i, --ascii Use only ASCII characters
GENERAL OPTIONS
-h, --help Print this help, then exit
-v, --version Print version information, then exit
Upon calling zmemtopo displays available topology level's structure
and memory increments defined on each topology location.
Ex:
$ zmemtopo
LPAR/LEVEL SIZE
LPAR003 8G
└LEVEL4_0 8G
├LEVEL3_0 2G
├LEVEL3_1 2G
├LEVEL3_2 2G
└LEVEL3_3 2G
LPAR005 8G
└LEVEL4_1 8G
├LEVEL3_0 2G
├LEVEL3_1 2G
├LEVEL3_2 2G
└LEVEL3_3 2G
LPAR006 8G
└LEVEL4_3 8G
