NAME

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

SYNOPSIS

9       cxl enable-port <port0> [<port1>..<portN>] [<options>]
10
11       A port typically autoenables at initial device discovery. However, if
12       it was manually disabled this command can trigger the kernel to
13       activate it again. This involves detecting the state of the HDM (Host
14       Managed Device Memory) Decoders and validating that CXL.mem is enabled
15       for each port in the device’s hierarchy.
16

OPTIONS

18       -e, --endpoint
19           Toggle from treating the port arguments as Switch Port identifiers
20           to Endpoint Port identifiers.
21
22       -m, --enable-memdevs
23           Try to enable descendant memdevs after enabling the port. Recall
24           that a memdev is only enabled after all CXL ports in its device
25           topology ancestry are enabled.
26
27       --debug
28           Turn on additional debug messages including library debug.
