ZonFS

This is a simple Storage Class Memory filesystem extended by Linux Ramfs. The detail of ZonFS is discussed in the following paper:

ZonFS: A Storage Class Memory File System with Memory Zone Partitioning on Linux <br> Jang Woong Kim, Jae-Hoon Kim, Awais Khan, Youngjae Kim and Sungyong Park<br> Published in AMGCC 2017

How to Use <br> ZonFS repo is a complete Linux kernel directory.

1. Install the kernel just like you used to do make a kernel.
2. Mount ZonFS just like you mount ramfs, but the name of file system is "kimfs" ex) mount -t kimfs -o size=512m kimfs /mnt/whatever

Caveat

1. ZonFS runs only on x86 machine.
2. You need to have at least 16GB DRAM. If your machine has less than 16GB memory, modify STORAGE_ZONE_ADDRESS and STORAGE_ZONE_SIZE defined in arch/x86/mm/init.c.
3. The 4.7.4 kernel, on which ZonFS is built, the maximum number of memory zones is 4. Therefore, you can have at maximum three zones, thus saving one for ZonFS.
