Subject[GIT PULL] perf changes
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: 3eb9ede23bdd96e9ba60e2b4d4d17a7c35d58448 Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Kernel side changes:

- Intel Knights Landing support. (Harish Chegondi)

- Intel Broadwell-EP uncore PMU support. (Kan Liang)

- Core code improvements. (Peter Zijlstra.)

- Event filter, LBR and PEBS fixes. (Stephane Eranian)

- Enable cycles:pp on Intel Atom. (Stephane Eranian)

- Add cycles:ppp support for Skylake. (Andi Kleen)

- Various x86 NMI overhead optimizations. (Andi Kleen)

- Intel PT enhancements. (Takao Indoh)

- AMD cache events fix. (Vince Weaver)

Tons of tooling changes:

- Show random perf tool tips in the 'perf report' bottom line (Namhyung Kim)

- perf report now defaults to --group if the perf.data file has grouped events, try it with:

# perf record -e '{cycles,instructions}' -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ]
# perf report
# Samples: 1K of event 'anon group { cycles, instructions }'
# Event count (approx.): 1955219195
#
# Overhead Command Shared Object Symbol

- Introduce the 'perf stat record/report' workflow:

Generate perf.data files from 'perf stat', to tap into the scripting
capabilities perf has instead of defining a 'perf stat' specific scripting
support to calculate event ratios, etc. Simple example:

$ perf stat record -e cycles usleep 1

Performance counter stats for 'usleep 1':

1,134,996 cycles

0.000670644 seconds time elapsed

$ perf stat report

Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1':

1,134,996 cycles

0.000670644 seconds time elapsed

$

It generates PERF_RECORD_ userspace records to store the details:

$ perf report -D | grep PERF_RECORD
0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637
0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535
0x12a [0x40]: PERF_RECORD_STAT_CONFIG
0x16a [0x30]: PERF_RECORD_STAT
-1 -1 0x19a [0x40]: PERF_RECORD_MMAP -1/0: [0xffffffff81000000(0x1f000000) @ 0xffffffff81000000]: x [kernel.kallsyms]_text
0x1da [0x18]: PERF_RECORD_STAT_ROUND
[acme@ssdandy linux]$

An effort was made to make perf.data files generated like this to not
generate cryptic messages when processed by older tools.

The 'perf script' bits need rebasing, will go up later.

- Make command line options always available, even when they
depend on some feature being enabled, warning the user about
use of such options (Wang Nan)

- Support hw breakpoint events (mem:0xAddress) in the default output mode in
'perf script' (Wang Nan)

- Fixes and improvements for supporting annotating ARM binaries, support ARM
call and jump instructions, more work needed to have arch specific stuff
separated into tools/perf/arch/*/annotate/ (Russell King)

- Add initial 'perf config' command, for now just with a --list command to the
contents of the configuration file in use and a basic man page describing
its format, commands for doing edits and detailed documentation are being
reviewed and proof-read. (Taeung Song)

- Allows BPF scriptlets specify arguments to be fetched using
DWARF info, using a prologue generated at compile/build time (He Kuang, Wang Nan)

- Allow attaching BPF scriptlets to module symbols (Wang Nan)

- Allow attaching BPF scriptlets to userspace code using uprobe (Wang Nan)

- BPF programs now can specify 'perf probe' tunables via its section name,
separating key=val values using semicolons (Wang Nan)

Testing some of these new BPF features:

Use case: get callchains when receiving SSL packets, filter then in the
kernel, at arbitrary place.

# cat ssl.bpf.c
#define SEC(NAME) __attribute__((section(NAME), used))

struct pt_regs;

SEC("func=__inet_lookup_established hnum")
int func(struct pt_regs *ctx, int err, unsigned short port)
{
return err == 0 && port == 443;
}

char _license[] SEC("license") = "GPL";
int _version SEC("version") = LINUX_VERSION_CODE;

#

Use 'perf probe' various options to list functions, see what variables can
be collected at any given point, experiment first collecting without a filter,
then filter, use it together with 'perf trace', 'perf top', with or without
callchains, if it explodes, please tell us!

- Introduce a new callchain mode: "folded", that will list per line
representations of all callchains for a give histogram entry, facilitating
'perf report' output processing by other tools, such as Brendan Gregg's
flamegraph tools (Namhyung Kim)

E.g:

# perf report | grep -v ^# | head
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry
|
---cpu_startup_entry
|
|--12.07%--start_secondary
|
--6.30%--rest_init
start_kernel
x86_64_start_reservations
x86_64_start_kernel
#

Becomes, in "folded" mode:

# perf report -g folded | grep -v ^# | head -5
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry
12.07% cpu_startup_entry;start_secondary
6.30% cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
16.90% 0.00% swapper [kernel.kallsyms] [k] call_cpuidle
11.23% call_cpuidle;cpu_startup_entry;start_secondary
5.67% call_cpuidle;cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
16.90% 0.00% swapper [kernel.kallsyms] [k] cpuidle_enter
11.23% cpuidle_enter;call_cpuidle;cpu_startup_entry;start_secondary
5.67% cpuidle_enter;call_cpuidle;cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
15.12% 0.00% swapper [kernel.kallsyms] [k] cpuidle_enter_state
#

The user can also select one of "count", "period" or "percent" as the first column.

... and lots of infrastructure enhancements, plus fixes and other changes,
features I failed to list - see the shortlog and the git log for details.

Thanks,

Ingo
