in [Kernel]
|
Prev: [PATCH/RFC v2 1/3] perfevents: Added performance event structure definition, export event description in the debugfs "perf_events_platform" file
Next: [PATCH/RFC v2 3/3] perf: Extended events (platform-specific) support in perf
From: Tomasz Fujak on 28 Jan 2010 04:40 Human readable description support for performance events v2. With perf support included. Changes from v1: - applied on top of latest perf_event/ARM (5899/1 - 5903/1) - moved to debugfs, now based on seq_file - reads one line at a time, memory overallocation fixed [perf] The following patches provide a sysfs entry with hardware event human readable description in the form of "0x%llx\t%lld-%lld\t%s\t%s" % (event_value, minval, maxval, name, description) and means to populate the file. The version posted contains ARMv6, ARMv7 (Cortex-A[89]) support in this matter. The intended use is twofold: for users to read the list directly and for tools (like perf).
