These patches are follow on patches of the kernel patches I sent out today: [PATCH 00/16] perf, persistent: Kernel updates for perf tool integration Persistent events are always enabled kernel events. Buffers are mapped readonly and multiple users are allowed. The persistent event flag of the event attribute must be set to specify such an event. The following changes to perf tools are necessary to support persistent events. A way is needed to specify sysfs entries to set event flags. For this a new syntax 'attr<num>' was added to the event parser, see patch #3. We also need to change perf tools to mmap persistent event buffers readonly. All patches can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/rric/oprofile.git persistent-v3 -Robert Robert Richter (4): perf tools: Rename flex conditions to avoid name conflicts perf tools: Modify event parser to update event attribute by index perf tools: Add attr<num> syntax to event parser perf tools: Retry mapping buffers readonly on EACCES tools/perf/builtin-record.c | 11 +++++--- tools/perf/builtin-top.c | 8 ++++-- tools/perf/perf.h | 1 + tools/perf/tests/parse-events.c | 12 ++++++--- tools/perf/util/parse-events.c | 59 +++++++++++++++++++---------------------- tools/perf/util/parse-events.h | 12 ++++----- tools/perf/util/parse-events.l | 56 +++++++++++++++++++++++--------------- tools/perf/util/parse-events.y | 24 ++++++++++------- tools/perf/util/pmu.c | 32 +++++----------------- tools/perf/util/pmu.h | 9 ++----- tools/perf/util/pmu.l | 1 + tools/perf/util/pmu.y | 18 ++++++++++--- 12 files changed, 129 insertions(+), 114 deletions(-) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
