NAME

6       cxl-disable-bus - Shutdown an entire tree of CXL devices
7

SYNOPSIS

9       cxl disable-bus <root0> [<root1>..<rootN>] [<options>]
10
11       For test and debug scenarios, disable a CXL bus and any associated
12       memory devices from CXL.mem operations.
13

OPTIONS

15       -f, --force
16           DANGEROUS: Override the safety measure that blocks attempts to
17           disable a bus if the tool determines a descendent memdev is in
18           active usage. Recall that CXL memory ranges might have been
19           established by platform firmware and disabling an active device is
20           akin to force removing memory from a running system.
21
22       --debug
23           If the cxl tool was built with debug disabled, turn on debug
24           messages.
