* perf evlist: Rename for_each() macros to for_each_entry()Arnaldo Carvalho de Melo2016-06-231-4/+4
| | | | | | | | | | | | | | | To match the semantics for list.h in the kernel, that are used to implement those macros.

* perf auxtrace: Add perf_evlist pointer to *info_priv_size()Mathieu Poirier2016-01-291-1/+3
| | | | | | | | | | | | | | | | | | | | | | | On some architecture the size of the private header may be dependent on the number of tracers used in the session. As such adding a "struct perf_evlist *" parameter, which should contain all the required information. Also adjusting the existing client of the interface to take the new parameter into account.

* perf tools: Add Intel BTS supportAdrian Hunter2015-08-211-0/+458
Intel BTS support fits within the new auxtrace infrastructure. Recording is supporting by identifying the Intel BTS PMU, parsing options and setting up events. Decoding is supported by queuing up trace data by thread and then decoding synchronously delivering synthesized event samples into the session processing for tools to consume.
