Introduction

This is a custom kernel module to perform CCA RSI operations from user space. It creates a /dev/rsi interface to be used with ioctl commands.

Most of the commands are from RSI specifications, some are Islet extensions.

Compilation

To compile and install you need 3 things:

1. KERNEL_DIR: directory where the kernel for the module build resides
2. OUTPUT_DIR: directory where to put the compiled module
3. Compiler: CROSS_COMPILE variable. Make sure the compiler is in PATH or set the COMPILER_DIR manually so the Makefile will add it to PATH.

Usage

Those ioctls are best used with higher level code available in the library and cmdline tool here:
