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.
