X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f575494d4a610278ea8597f2f798c8431b94e884;p=linux.git Merge tag 'perf-core-for-mingo-5.0-20190121' of git://git./linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: BPF: Song Liu: - Introduce PERF_RECORD_KSYMBOL to allow tooling to notice the addition of new kernel symbols and be able to resolve samples in such symbols. - Introduce PERF_RECORD_BPF_EVENT to notify tooling about the loading and unloading of BPF programs, making them visible and allowing for the request of further information to allow for things like annotation. - Change the userspace perf tools to handle those new events and to synthesize them for pre-existing loaded BPF programs. Kernel: Arnaldo Carvalho de Melo: - Make perf_event_output() propagate the output() return, allowing users to check for -ENOSPC in the ring buffer. perf report: Thomas Richter: - Display arch specific diagnostic counter sets, starting with s390 diagnostic counter sets. perf session: Jiri Olsa: - Introduce a reader object to prep for multithreaded processing of recorded events. Misc: Rasmus Villemoes: - Replace automatic const char[] variables by statics, to avoid initializing them at runtime, instead having them in .rodata, reducing code size. YueHaibing: - Remove duplicated workqueue.h include from perf_event.h Brajeswar Ghosh: - Remove some more duplicated headers.
