perf pmu: Use pmu_events table to create aliases

2016-10-03T22:58:00Z

At run time (when 'perf' is starting up), locate the specific table of PMU events that corresponds to the current CPU. Using that table, create aliases for the each of the PMU events in the CPU. The use these aliases to parse the user specified perf event. In short this would allow the user to specify events using their aliases rather than raw event codes. Based on input and some earlier patches from Andi Kleen, Jiri Olsa.

perf tools: Add perf data cache feature

2016-02-16T20:13:00Z

Storing CPU cache details under perf data. It's stored as new HEADER_CACHE feature and it's displayed under header info with -I option: $ perf report --header-only -I ... # CPU cache info: # L1 Data 32K [0-1] # L1 Instruction 32K [0-1] # L1 Data 32K [2-3] # L1 Instruction 32K [2-3] # L2 Unified 256K [0-1] # L2 Unified 256K [2-3] # L3 Unified 4096K [0-3] ...

perf tools: Introduce stat perf.data header feature

2015-12-17T18:15:14Z

Introducing the 'stat' feature to mark a perf.data as created by the 'perf stat record' command. It contains no data. It's needed so that the report tools (report/script) can differentiate sampling data from counting data, because they need to be treated in a different way. In the future it might be used to store the version of the stat storage system used.

perf tools: Add event_update user level event

2015-12-17T18:10:16Z

It'll serve as a base event for additional event attributes details, that are not part of the attr event. At the moment this event is just a dummy one without any specific functionality. The type value will distinguish the update event details. It'll come in the following patches. The idea for this event is to be extensible for any update that the event might need in the future.
