Tried `make`ing on two machines (with Arch Linux and Manjaro Linux), encountered the same error: ``` make[2]: Entering directory '.../uarch-bench/libpfc/kmod.build' make -C /lib/modules/6.6.10-arch1-1/build M=.../uarch-bench/libpfc/kmod.build modules make[3]: Entering directory '.../uarch-bench/libpfc/kmod.build' make[3]:...

I tried to reproduce the results in this article. I know that uarch-bench can use perf, but since I always get jevents errors, I made a simple implementation of this...

Thanks for all the great work! Anybody had this problem? I'm on ubuntu, the cpu is AMD Ryzen and I'm getting it by running: `/uarch-bench.sh --test-name=cpp/sum-halves --timer=perf`

OSX support

Should be easy to support OSX, in fact perhaps it already works. We don't have a solution for reading performance counters on OSX, and it isn't clear the effort required...
