Hello Fabien,
Thank you for your +1 :)

Yes, you can emulate PMEM using DRAM on Linux, via "memmap=nnG!ssG" kernel
parameter. Please see [1] and [2] for emulation details. If your emulation
does not work well, please check if the kernel configuration options (like
CONFIG_ FOOBAR) for PMEM and DAX (in [1] and [3]) are set up properly.
Best regards,
Takashi
