Linus,

Please pull the latest perf-core-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus

# HEAD: 5048c2af078d5976895d521262a8802ea791f3b0 Merge tag 'perf-core-for-mingo-20160718' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

With over 300 commits it's been a busy cycle - with most of the work concentrated
on the tooling side (as it should). The main kernel side enhancements were:

- Add per event callchain limit: Recently we introduced a sysctl to tune the
max-stack for all events for which callchains were requested:

$ sysctl kernel.perf_event_max_stack
kernel.perf_event_max_stack = 127

Now this patch introduces a way to configure this per event, i.e. this
becomes possible:

$ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

allowing finer tuning of how much buffer space callchains use.

This uses an u16 from the reserved space at the end, leaving another
u16 for future use.

There has been interest in even finer tuning, namely to control the
max stack for kernel and userspace callchains separately. Further
discussion is needed, we may for instance use the remaining u16 for
that and when it is present, assume that the sample_max_stack introduced
in this patch applies for the kernel, and the u16 left is used for
limiting the userspace callchain. (Arnaldo Carvalho de Melo)

- Optimize AUX event (hardware assisted side-band event) delivery (Kan Liang)

- Rework Intel family name macro usage (this is partially x86 arch work)
(Dave Hansen)

- Refine and fix Intel LBR support (David Carrillo-Cisneros)

- Add support for Intel 'TopDown' events (Andi Kleen)

- Intel uncore PMU driver fixes and enhancements (Kan Liang)

- ... other misc changes.

Here's an incomplete list of the tooling enhancements (but there's much more, see
the shortlog and the git log for details):

- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
in one machine and then doing analysis in another machine of a different
hardware architecture. This enables, for instance, to do:

perf record -a --call-graph dwarf

on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation. (He Kuang)

- Allow reading from a backward ring buffer (one setup via sys_perf_event_open()
with perf_event_attr.write_backward = 1) (Wang Nan)

- Finish merging initial SDT (Statically Defined Traces) support, see
cset comments for details about how it all works (Masami Hiramatsu)

- Support attaching eBPF programs to tracepoints (Wang Nan)

- Add demangling of symbols in programs written in the Rust language (David Tolnay)

- Add support for tracepoints in the python binding, including an example, that
sets up and parses sched:sched_switch events, tools/perf/python/tracepoint.py
(Jiri Olsa)

- Introduce --stdio-color to set up the color output mode selection in
'annotate' and 'report', allowing emit color escape sequences when
redirecting the output of these tools (Arnaldo Carvalho de Melo)

- Add 'callindent' option to 'perf script -F', to indent the Intel PT
call stack, making this output more ftrace-like (Adrian Hunter, Andi Kleen)

- Allow dumping the object files generated by llvm when processing eBPF
scriptlet events (Wang Nan)

- Add stackcollapse.py script to help generating flame graphs (Paolo Bonzini)

- Add --ldlat option to 'perf mem' to specify load latency for loads
event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

- Tooling support for Intel TopDown counters, recently added to the kernel (Andi Kleen)

Thanks,

Ingo
