cxl-enable-port(1)

Usage

cxl enable-port <port0> [<port1>..<portN>] [<options>]

-e, --endpoint: Toggle from treating the port arguments as Switch Port identifiers to Endpoint Port identifiers.

-m, --enable-memdevs: Try to enable descendant memdevs after enabling the port. Recall that a memdev is only enabled after all CXL ports in its device topology ancestry are enabled.

Note: The '-m' option requires release v83 or newer when used with kernel v6.18 or later. Older releases (before v83) will not work because kernel v6.18 changed how CXL ports and downstream ports are enumerated. In these newer kernels, the CXL port hierarchy is only established once the memdev is probed. v83 and later remain fully compatible with both older and newer kernels.
