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
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 If the cxl tool was built with debug enabled, turn on debug
29 messages.
