# cxl-disable-port(1) ## NAME cxl-disable-port - activate / hot-add a given CXL port ## SYNOPSIS cxl disable-port \ \[\..\] \[\] 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. Toggle from treating the port arguments as Switch Port identifiers to Endpoint Port identifiers. \--debug If the cxl tool was built with debug disabled, turn on debug messages. ## COPYRIGHT Copyright © 2016 - 2022, Intel Corporation.
