CXL-DISABLE-PORT(1)

NAME
cxl-disable-port - activate / hot-add a given CXL port

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.

        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.
