NAME

cxl-disable-port − disable / hot−remove a given CXL port and descendants

SYNOPSIS

cxl disable−port <port0> [<port1>..<portN>] [<options>]

For test and debug scenarios, disable a CXL port and any memory devices dependent on this port being active for CXL.mem operation.

OPTIONS

−e, −−endpoint

Toggle from treating the port arguments as Switch Port identifiers to Endpoint Port identifiers.

−f, −−force

DANGEROUS: Override the safety measure that blocks attempts to disable a port if the tool determines a descendent memdev is in active usage. Recall that CXL memory ranges might have been established by platform firmware and disabling an active device is akin to force removing memory from a running system.

−−debug

Turn on additional debug messages including library debug.
