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.
