- Introduce 'perf record --aio' to use asynchronous IO trace writing, disabled by default (Alexey Budankov) - Add fallback routines to be used in places where we don't have the CPU mode (kernel/userspace/hypervisor) and thus must first fallback lookups looking at all map trees when trying to resolve symbols (Adrian Hunter) - Fix error with config term "pt=0", where we should just force "pt=1" and warn the user about the former being nonsensical (Adrian Hunter) - Fix 'perf test' entry where we expect 'sleep' to come in a PERF_RECORD_COMM but instead we get 'coreutils' when sleep is provided by some versions of the 'coreutils' package (Adrian Hunter) - Introduce 'perf top --kallsyms file' to match 'perf report --kallsyms', useful when dealing with BPF, where symbol resolution happens via kallsyms, not via the default vmlinux ELF symtabs (Arnaldo Carvalho de Melo) - Support 'srccode' output field in 'perf script' (Andi Kleen) - Introduce basic 'perf annotation' support for the ARC architecture (Eugeniy Paltsev) - Compute and display average IPC and IPC coverage per symbol in 'perf annotate' and 'perf report' (Jin Yao) - Make 'perf top' use ordered_events and process histograms in a separate thread (Jiri Olsa) - Make 'perf trace' use ordered_events (Jiri Olsa) - Add support for ETMv3 and PTMv1.1 decoding in cs-etm (Mathieu Poirier) - Support for ARM A32/T32 instruction sets in CoreSight trace (cs-etm) (Robert Walker) - Fix 'perf stat' shadow stats for clock events. (Ravi Bangoria) - Remove needless rb_tree extra indirection from map__find() (Eric Saint-Etienne) - Fix CSV mode column output for non-cgroup events in 'perf stat' (Stephane Eranian) - Add sanity check to libtraceevent's is_timestamp_in_us() (Tzvetomir Stoyanov) - Use ERR_CAST instead of ERR_PTR(PTR_ERR()) (Wen Yang) - Fix Load_Miss_Real_Latency on SKL/SKX intel vendor event files (Andi Kleen) - strncpy() fixes triggered by new warnings on gcc 8.2.0 (Arnaldo Carvalho de Melo) - Handle tracefs syscall tracepoint older 'nr' field in 'perf trace', that got renamed to '__syscall_nr' to work in older kernels (Arnaldo Carvalho de Melo) - Give better hint about devel package for libssl (Arnaldo Carvalho de Melo) - Fix the 'perf trace' build in architectures lacking explicit mmap.h file (Arnaldo Carvalho de Melo) - Remove extra rb_tree traversal indirection from map__find() (Eric Saint-Etienne) - Disable breakpoint tests for 32-bit ARM (Florian Fainelli) - Fix typos all over the place, mostly in comments, but also in some debug messages and JSON files (Ingo Molnar) - Allow specifying proc-map-timeout in config file (Mark Drayton) - Fix mmap_flags table generation script (Sihyeon Jang) - Fix 'size' parameter to snprintf in the 'perf config' code (Sihyeon Jang) - More libtraceevent renames to make it a proper library (Tzvetomir Stoyanov) - Implement new API tep_get_ref() in libtraceevent (Tzvetomir Stoyanov) - Added support for pkg-config in libtraceevent (Tzvetomir Stoyanov) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQR2GiIUctdOfX2qHhGyPKLppCJ+JwUCXBfqKQAKCRCyPKLppCJ+ JwB3AQCn2ij14Y2W4Cvy0ka18LZlxQkC0b+L30XZwUv9q34FSwD9HyErhRWTQhEU PgPdn6TKqh9aYy7LRFACiQ4x/s7Dug8= =xxUZ -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.21-20181217' 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: - Introduce 'perf record --aio' to use asynchronous IO trace writing, disabled by default (Alexey Budankov) - Add fallback routines to be used in places where we don't have the CPU mode (kernel/userspace/hypervisor) and thus must first fallback lookups looking at all map trees when trying to resolve symbols (Adrian Hunter) - Fix error with config term "pt=0", where we should just force "pt=1" and warn the user about the former being nonsensical (Adrian Hunter) - Fix 'perf test' entry where we expect 'sleep' to come in a PERF_RECORD_COMM but instead we get 'coreutils' when sleep is provided by some versions of the 'coreutils' package (Adrian Hunter) - Introduce 'perf top --kallsyms file' to match 'perf report --kallsyms', useful when dealing with BPF, where symbol resolution happens via kallsyms, not via the default vmlinux ELF symtabs (Arnaldo Carvalho de Melo) - Support 'srccode' output field in 'perf script' (Andi Kleen) - Introduce basic 'perf annotation' support for the ARC architecture (Eugeniy Paltsev) - Compute and display average IPC and IPC coverage per symbol in 'perf annotate' and 'perf report' (Jin Yao) - Make 'perf top' use ordered_events and process histograms in a separate thread (Jiri Olsa) - Make 'perf trace' use ordered_events (Jiri Olsa) - Add support for ETMv3 and PTMv1.1 decoding in cs-etm (Mathieu Poirier) - Support for ARM A32/T32 instruction sets in CoreSight trace (cs-etm) (Robert Walker) - Fix 'perf stat' shadow stats for clock events.
