Performance Profiling

Kernel

TBA

Perf

The default Debian kernel does not have the perf tool enabled. We need to compile it in order to use the perf tool like in a stock OS.

  1. Clone the custom kernel repo into the VM:

git clone /path/to/custom/kernel/repo kernel
cd kernel

  1. Install dependencies:

sudo apt install libelf-dev libdw-dev libunwind-dev

  1. Compile

cd tools/perf && make -j16

After the compilation succeeds, you will see the perf executable in the directory. And you can use the sudo ./perf ... command.
