With this microbenchmark we can measure the overhead of emulating atomic instructions with a configurable degree of contention. The benchmark spawns $n threads, each performing $o atomic ops (additions) in a loop. Each atomic operation is performed on a different cache line (assuming lines are 64b long) that is randomly selected from a range [0, $r).

It's been superseded by the atomic helpers. The use of the atomic helpers provides a significant performance and scalability improvement. Below is the result of running the atomic_add-test microbenchmark with: $ x86_64-linux-user/qemu-x86_64 tests/atomic_add-bench -o 5000000 -r $r -n $n , where $n is the number of threads and $r is the allowed range for the additions. The scenarios measured are: - atomic: implements x86' ADDL with the atomic_add helper (i.e. this patchset) - cmpxchg: implement x86' ADDL with a TCG loop using the cmpxchg helper - master: before this patchset Results sorted in ascending range, i.e. descending degree of contention.
