cxl-disable-bus - Man Page
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.
