Linux kernel character driver and app program for prototype hardware. The idea is this is useful as as a basic framework and reusable code.

This is a complete systems software from kernel driver to user-space application program. Developed as an systems software prototype memory storage type hardware for cloud servers, in-memory computing, and high-performance computing.

Taken as it is without prototype hardware available, it is using RAM space as scratch memory and exercising data movement between Linux user-space to kernel space to memory hardware. A full top-to-bottom software solution in Linux.

Some features from user space program to access the memory:

• read()
• write()
• mmap(): The sleak way to access physical memory from user space. User can map kernel physical memory into kernel virtual memory and then mapped directly into user-space virtual memory. User can then use its user-space virtual memory to do data manipulation and the changes are directly reflected in the physical memory.

Written in C.

Tested on Linux CentOS 7 distribution.
