cxl-disable-port - Man Page

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.

-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.
