Hi, In a separate thread, some folks were looking for some simple benchmarks for evaluating various changes to kernel internals (as opposed to the much more focused things like xfstests). For me, this has been an area of lore and passed-around scripts, and it seems like maybe we should have a subdirectory of tools/testing/benchmarks/ or something to collect these?
(Or maybe this already exists and I've totally missed it?) I've got at least one micro-benchmark in tools/testing/selftests/seccomp/seccomp_benchmark.c, and searches show tools/testing/selftests/vm/gup_benchmark.c too, but I was thinking of either more generali things more like the famous "kernel build benchmark" or a wrapper for running hackbench to get some statistics out of it, etc. Or, I guess, at least collecting all the micro-benchmarks in some single place, as they're a bit scattered. I'm sure I'm not remotely the first person to bring this up, but my attempts at searches for this have failed. Thoughts? -Kees -- Kees Cook Pixel Security
