CXL-ENABLE-REGION(1) cxl Manual CXL-ENABLE-REGION(1)

NAME

cxl-enable-region - enable specified region(s).

SYNOPSIS

cxl enable-region <region> [<options>]

DESCRIPTION

A CXL region is composed of one or more slices of CXL memdevs, with configurable interleave settings - both the number of interleave ways, and the interleave granularity.

EXAMPLE

# cxl enable-region all
enabled 2 regions

Given any enable or disable command, if the operation is a no-op due to the current state of a target (i.e. already enabled or disabled), it is still considered successful when executed even if no actual operation is performed. The target can be a bus, decoder, memdev, or region. The operation will still succeed, and report the number of bus/decoder/memdev/region operated on, even if the operation is a no-op.

OPTIONS

-b, --bus=

Restrict the operation to the specified bus.

-d, --decoder=

The root decoder to limit the operation to. Only regions that are children of the specified decoder will be acted upon.

--debug

Turn on additional debug messages including library debug.
