# cxl list --memdevs
{


  "memdev":"mem0",


  "pmem_size":268435456,


  "ram_size":0,
}

Specify a cxl memory device name to filter the listing. For example:

# cxl list --memdev=mem0
{


  "memdev":"mem0",


  "pmem_size":268435456,


  "ram_size":0,
}

Include CXL memory devices in the listing

Include idle (not enabled / zero-sized) devices in the listing

Include health information in the memdev listing. Example listing:

# cxl list -m mem0 -H
