NAME

cxl-disable-bus − Shutdown an entire tree of CXL devices

SYNOPSIS

cxl disable−bus <root0> [<root1>..<rootN>] [<options>]

For test and debug scenarios, disable a CXL bus and any associated memory devices from CXL.mem operations.

OPTIONS

−f, −−force

DANGEROUS: Override the safety measure that blocks attempts to disable a bus 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

If the cxl tool was built with debug disabled, turn on debug messages.
