NAME

6       cxl-disable-port - activate / hot-add a given CXL port
7

SYNOPSIS

9       cxl disable-port <port0> [<port1>..<portN>] [<options>]
10
11       For test and debug scenarios, disable a CXL port and any memory devices
12       dependent on this port being active for CXL.mem operation.
13

OPTIONS

15       -e, --endpoint
16           Toggle from treating the port arguments as Switch Port identifiers
17           to Endpoint Port identifiers.
18
19       -f, --force
20           DANGEROUS: Override the safety measure that blocks attempts to
21           disable a port if the tool determines a descendent memdev is in
22           active usage. Recall that CXL memory ranges might have been
23           established by platform firmware and disabling an active device is
24           akin to force removing memory from a running system.
25
26               Toggle from treating the port arguments as Switch Port identifiers to
27               Endpoint Port identifiers.
28
29       --debug
30           If the cxl tool was built with debug disabled, turn on debug
31           messages.
