Hi Norrathep,

What sort of benchmarking would you like to do?

libsel4bench: https://github.com/seL4/seL4_libs/tree/master/libsel4bench provides primitives for reading cycle counters etc.

For benchmarking inside the kernel itself, we have some minimal support for adding trace points in this file: https://github.com/seL4/seL4/blob/master/include/benchmark.h

In the next few weeks we'll be releasing the seL4 benchmarking suite.

Thanks,
Anna.

Hello,

What's the best way to benchmark my program inside sel4? I saw wiki page about running sel4 bench (https://wiki.sel4.systems/Benchmarking%20guide) but it wasnt filled yet. So I wonder if there's any public guide or tutorial on that?

I also found this https://github.com/seL4/libplatsupport/blob/master/arch_include/x86/platsupport/arch/tsc.h

and tried both rdtsc_pure and rdtsc_cpuid but neither of them seems to produce reliable results.

Best,
