NVM-LKernel

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.

Required Package

• gcc
• make
• bc
• build-essential
• kernel-package
• libncurses5-dev
• libqt3-mt-dev
  (# apt install *** or # yum install *** )

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   

Mount with PRAMFS
Example:

# mount -t pramfs -o physaddr=0x100000000,init=100M,bs=1k none /mnt/pram

Mount with PRAMFS(XIP)
Example:

# mount -t pramfs -o physaddr=0x100000000,init=2000M,bs=4096,xip none /mnt/pram

When you want to mount without initializing after unmount
Example:

# mount -t pramfs -o physaddr=0x100000000,init=2000M,bs=4096,xip,noinit none /mnt/pram

File System

• pramfs (Original File System)
• improved-pramfs (Improved File System)

Support

• Debian
• Ubuntu
• CentOS
• Fedora
• Red Hat Enterprise Linux

Beta Version

nvm-lkernel-beta
