I had difficulty applying the patches to the perf-tools-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/log/?h=perf-tools-next using patch and dealing with rejects I was able to test. Reviewed-by: Ian Rogers <irogers@xxxxxxxxxx> On x86-64: Tested-by: Ian Rogers <irogers@xxxxxxxxxx> I think there are follow up patches that clean up the ABI, allow >1 table at a time, .. but those things are best saved for a follow up.
