Subject: [GIT PULL] perf updates for v4.15
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: fcdfafcb73be8fa45909327bbddca46fb362a675 kprobes: Don't spam the build log with deprecation warnings
The main changes in this cycle were:
- kprobes updates: use better W^X patterns for code modifications, improve
optprobes, remove jprobes. (Masami Hiramatsu, Kees Cook)
- core fixes: event timekeeping (enabled/running times statistics) fixes,
perf_event_read() locking fixes and cleanups, etc. (Peter Zijlstra)
- Extend x86 Intel free-running PEBS support and support x86 user-register
sampling in perf record and perf script. (Andi Kleen)
- Tooling updates:
- Completely rework the way inline frames are handled. Instead of querying
for the inline nodes on-demand in the individual tools, we now create
proper callchain nodes for inlined frames. (Milian Wolff)
- 'perf trace' updates (Arnaldo Carvalho de Melo)
- Implement a way to print formatted output to per-event files in 'perf script'
to facilitate generate flamegraphs, elliminating the need to write scripts to
do that separation (yuzhoujian, Arnaldo Carvalho de Melo)
- Update vendor events JSON metrics for Intel's Broadwell, Broadwell
Server, Haswell, Haswell Server, IvyBridge, IvyTown, JakeTown, Sandy
Bridge, Skylake, SkyLake Server - and Goldmont Plus V1 (Andi Kleen, Kan Liang)
- Multithread the synthesizing of PERF_RECORD_ events for pre-existing
threads in 'perf top', speeding up that phase, greatly improving the
user experience in systems such as Intel's Knights Mill (Kan Liang)
- Introduce the concept of weak groups in 'perf stat': try to set up a
group, but if it's not schedulable fallback to not using a group. That
gives us the best of both worlds: groups if they work, but still a
usable fallback if they don't. E.g: (Andi Kleen)
- perf sched timehist enhancements (David Ahern)
- ... various other enhancements, updates, cleanups and fixes.
Thanks,
Ingo
