| Assuming your linux kernel supports Device DAX properly, the following describes a full procedure of how to set up 2 Device DAXes of 1G and 2G sizes on a machine with 32G RAM. | |
| 1. Configure grub. | |
| Add the following line to /etc/default/grub: | |
| GRUB_CMDLINE_LINUX="memmap=1G!31G memmap=2G!29G" | |
| (meaning: take 1G after 31G of your RAM and 2G after 29G of RAM, which makes the last 3G of your RAM devoted to Device DAXex) | |
| 2. Update grub. | |
| $ sudo update-grub2 |
