Tested on Linux v5.6.6-300 and v5.6.13-100. No guarantees about other versions.
To build the executor, run:
cd src/executor/x86
sudo rmmod x86-executor
make clean
make
sudo insmod x86-executor.ko
Use the Revizor CLI (src/cli.py).
This executor is not meant to be used standalone.
On your own peril, you could try using it directly, through the /sys/x86-executor/ pseudo file system.
You can find an example of how to use it in src/executor.py:X86Intel.
But I promise you, it's a bad idea.
Better not.
