vma_explorer

I tested on Linux 6.11.0-9-generic.

Build vma_explorer Linux kernel module.

make

Load vma_explorer Kernel Module.

sudo insmod vma_explorer.ko 

Get log from /proc/vma_info.

sudo cat /proc/vma_info > vma_explorer.log

Split log from vma_explorer.log.

./split_process_vma_log.awk vma_explorer.log

This is the example of log that after executed split_process_vma_log.awk.
