NAME
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.
