Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

This is used when calculating the difference in the counts of events when using interval. The current counts are stored in prev_raw_counts to calculate the differences in the next iteration. On the first interval of the second and subsequent repetitions, prev_raw_counts would be the values stored in the last interval of the previous repetitions, while the current counts will only be for the first interval of the current repetition. Hence there is a possibility of events showing up as big number. Fix this by resetting prev_raw_counts whenever perf stat repeats the command.

As such, with the following cmdline: $ perf record -e cycles date The perf tool first tries cycles:uk but then falls back to cycles:u as can be seen in the perf report --header-only output: cmdline : /export/hda3/tmp/perf.tip record -e cycles ls event : name = cycles:u, , id = { 436186, ... } This is okay as long as there is way to learn the priv level was changed internally by the tool. But consider a similar example: $ perf record -b -e cycles date Error: You may not have permission to collect stats. Consider tweaking /proc/sys/kernel/perf_event_paranoid, which controls use of the performance events system by unprivileged users (without CAP_SYS_ADMIN). ... Why is that treated differently given that the branch sampling inherits the priv level of the first event in this case, i.e., cycles:u? It turns out that the branch sampling code is more picky and also checks exclude_hv. In the fallback path, perf record is setting exclude_kernel = 1, but it does not change exclude_hv. This does not seem to match the restriction imposed by paranoid = 2. This patch fixes the problem by forcing exclude_hv = 1 in the fallback for paranoid=2. With this in place: $ perf record -b -e cycles date cmdline : /export/hda3/tmp/perf.tip record -b -e cycles ls event : name = cycles:u, , id = { 436847, ... } And the command succeeds as expected. V2 fix a white space.

struct Add the perf_mmap struct to libperf. The definition is added into: include/internal/mmap.h which is not to be included by users, but shared within perf and libperf.
