No, everything shows as daxX.Y character devices across hmem and pmem producers. For example: # daxctl list -RDu [ { "path":"/platform/hmem.1", "id":1, "size":"4.00 GiB (4.29 GB)", "align":2097152, "devices":[ { "chardev":"dax1.0", "size":"4.00 GiB (4.29 GB)" } ] }, { "path":"/LNXSYSTM:00/LNXSYBUS:00/ACPI0012:00/ndbus0/region2/dax2.1", "id":2, "size":"125.01 GiB (134.23 GB)", "align":2097152, "devices":[ { "chardev":"dax2.0", "size":"125.01 GiB (134.23 GB)" } ] }, { "path":"/platform/hmem.0", "id":0, "size":"4.00 GiB (4.29 GB)", "align":2097152, "devices":[ { "chardev":"dax0.0", "size":"4.00 GiB (4.29 GB)" } ] } ]
