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.
