Non-Volatile Memory Based Linux Kernel

Summary

This project is a Linux Kernel for high-speed nonvolatile memory.
I have improved for high-speed nonvolatile memory based on Linux-3.12.49 source code.

How to

Build and Boot NVM-LKernel

# ./do.sh   
# reboot   

Boot NVM-LKernel

# ./set_grub.sh nvm   
# reboot   

Boot Default Linux Kernel

# ./set_grub.sh default   
# reboot
