I do this here in the lab all the time. with a "command line" with this code you see here. [DDR3 NvDIMM which means I need memmap=16G\$32G on Kernel command line. Then: modprobe pmem map=8G@32G,4G@44G,... and so on Just as a simple example where 2/4-3/4 addresses are not used. You can have holes in the middle or what ever you want. This here is just a table in comma-separated format. If we need like flags in future we can extend the format to nn@ss:flags, but I do no have any 3rd column yet] And again I have in the pipe a dynamic interface added on top of the module param one. So it will all be there soon. Without reverting the old one.
