perf/core improvements and fixes:
- Start using BPF maps in 'perf trace' for filters in the augmented syscalls code, keeping the existing code for tracepoint filters so that we can switch back and forth while getting everything BPFied (Arnaldo Carvalho de Melo) - Suppress potential format-truncation warning in the PMU code (Ben Hutchings) - Introduce 'perf bench epoll', with "wait" and "ctl" benchmarks (Davidlohr Bueso) - Fix slowness due to -ffunction-section, do it by sorting the maps by name, so avoiding the using rb_first/next to traverse all entries looking for a map name, that with --ffunction-section gets to thousands of maps (Eric Saint-Etienne) - Separate jvmti cmlr check (Jiri Olsa) - Allow using the stepping when figuring out which JSON files to use for a x86 processor, so that Cascadelake server can be support, which has the same cpuid as some other processor, being different only in the stepping (Kan Liang) - Share code and output format for uregs and iregs 'perf script' output (Milian Wolff) - Use perf_evsel__is_clocki() for clock events in 'perf stat' (Ravi Bangoria) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iHQEABYIAB0WIQR2GiIUctdOfX2qHhGyPKLppCJ+JwUCW/YiKQAKCRCyPKLppCJ+ J3qLAPjy8imSBJP/odU0G/cvcAQ3nUXfv4c9j7+5iWmb4kJhAQCt+SyEhsnOqlwf 9XyquKIwcz05D7HlSDlRngL9Y7W3CQ== =ncNT -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.21-20181122' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: - Start using BPF maps in 'perf trace' for filters in the augmented syscalls code, keeping the existing code for tracepoint filters so that we can switch back and forth while getting everything BPFied (Arnaldo Carvalho de Melo) - Suppress potential format-truncation warning in the PMU code (Ben Hutchings) - Introduce 'perf bench epoll', with "wait" and "ctl" benchmarks (Davidlohr Bueso) - Fix slowness due to -ffunction-section, do it by sorting the maps by name, so avoiding the using rb_first/next to traverse all entries looking for a map name, that with --ffunction-section gets to thousands of maps (Eric Saint-Etienne) - Separate jvmti cmlr check (Jiri Olsa) - Allow using the stepping when figuring out which JSON files to use for a x86 processor, so that Cascadelake server can be support, which has the same cpuid as some other processor, being different only in the stepping (Kan Liang) - Share code and output format for uregs and iregs 'perf script' output (Milian Wolff) - Use perf_evsel__is_clocki() for clock events in 'perf stat' (Ravi Bangoria) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
