This example demonstrates how to extend the Bareflank hypervisor to trap read accesses to a page using the extended page tables.
To setup this extension, run the following (assuming Linux):
git clone https://github.com/bareflank/hypervisor
git clone https://github.com/bareflank/extended_apis
git clone https://github.com/jaredwright/ept_example.git
mkdir build; cd build
cmake ../hypervisor -DCONFIG=ept_example/config.cmake
make -j<# cores + 1>
To load this extension, run the following commands:
make driver_quick
make quick
This extension will trap read access to a page managed by the VMM as the VMM
is being unloaded. Therfore, you will not be able to view this extension's
output from the typical make dump command. Connect to your enviornment's
serial port to view output using the following:
make unload
make driver_unload
