This patch kit further improves support for Intel uncore events in
the Linux perf user tool. The basic support has been already
merged earlier, but this makes it nicer to use.
- Collapse counts from duplicated boxes to make the output
easier to read.
- Support specifying events for multiple duplicated boxes
in an abbreviated format to shorten event specifiers
- Add support for computing Metrics defined in the event lists,
so that the event lists can extend the metrics in perf stat.
This allows to represent many events in an easier to understand
format.
Available from
git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc.git perf/builtin-json-29
v1: Initial post after being split off to own patchkit
Adding MetricName support and support for more than two events
in expressions.
v2: Address review comments. Move new hunk from refactor
patchkit to patch adding new features. Improve changelogs
slightly.
v3: Rebased on latest tip tree.
Split some patches based on review feedback.
Add event list changes for MetricName
Move extra printing in perf list to new option
Improve descriptions
Cleanups based on code review.

From: Andi Kleen <ak@linux.intel.com>
The uncore PMU has a lot of duplicated PMUs for different subsystems.
When expanding an uncore alias we usually end up with a large
number of identically named aliases, which makes perf stat
output difficult to read.
Automatically sum them up in perf stat, unless --no-merge is specified.
This can be default because only the uncores generally have duplicated
aliases. Other PMUs have unique names.
Before:
% perf stat --no-merge -a -e unc_c_llc_lookup.any sleep 1
Performance counter stats for 'system wide':
694,976 Bytes unc_c_llc_lookup.any

Performance counter stats for 'system wide':
2,685,120 Bytes unc_c_llc_lookup.any

v2: Split collect_aliases. Rename alias flag.
v3: Make sure unsupported/not counted is always printed.
v4: Factor out callback change into separate patch.
v5: Move check for bad results here
Move merged check into collect_data

When any result that is being merged is bad, mark them all
bad to give consistent output in interval mode.
No before/after, because the issue was only found in theoretical
review and it is hard to reproduce

From: Andi Kleen <ak@linux.intel.com>
When the user specifies a pmu directly, expand it automatically
with a prefix match for all available PMUs, similar as we do for
the normal aliases now.
This allows to specify attributes for duplicated boxes quickly.
For example uncore_cbox_{0,6}/.../ can be now specified as uncore_cbox/.../
and it gets automatically expanded for all boxes.
This generally makes it more concise to write uncore specifications, and
also avoids the need to know the exact topology of the system.
Before
% perf stat -a -e uncore_cbox_0/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_1/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_2/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_3/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_4/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_5/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
After
% perf stat -a -e uncore_cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
v2: Handle all bison rules. Move multi add code to separate function.
Handle uncore_ prefix correctly.
v3: Move parse_events_multi_pmu_add to separate patch. Move uncore
prefix check to separate patch.

From: Andi Kleen <ak@linux.intel.com>
Add a simple expression parser good enough to parse JSON relation
expressions. The parser is implemented using bison.
This is just intended as an simple parser for internal usage
in the event lists, not the beginning of a "perf scripting language"
v2: Use expr__ prefix instead of expr_
Support multiple free variables for parser

From: Andi Kleen <ak@linux.intel.com>
Add support for parsing the MetricExpr header in the JSON event lists and
storing them in the alias structure.
Used in the next patch.
v2: Change DividedBy to MetricExpr
v3: Really catch all uses of DividedBy

From: Andi Kleen <ak@linux.intel.com>
Add generic infrastructure to perf stat to output ratios for "MetricExpr"
entries in the event lists. Many events are more useful as ratios
than in raw form, typically some count in relation to total ticks.
Transfer the MetricExpr information from the alias to the evsel.
We mark the events that need to be collected for MetricExpr, and also
link the events using them with a pointer. The code is careful
to always prefer the right event in the same group to minimize
multiplexing errors. At the moment only a single relation is supported.
Then add a rblist to the stat shadow code that remembers stats based
on the cpu and context.
Then finally update and retrieve and print these values similarly to the
existing hardcoded perf metrics. We use the simple expression parser
added earlier to evaluate the expression.
Normally we just output the result without further commentary,
but for --metric-only this would lead to empty columns. So for this
case use the original event as description.
There is no attempt to automatically add the MetricExpr event,
if it is missing, however we suggest it to the user, because
the user tool doesn't have enough information to reliably
construct a group that is guaranteed to schedule. So we leave
that to the user.
% perf stat -a -I 1000 -e '{unc_p_clockticks,unc_p_freq_max_os_cycles}'
1.000147889 800,085,181 unc_p_clockticks

% perf stat -a -I 1000 -e '{unc_p_clockticks,unc_p_freq_max_os_cycles}' --metric-only
1.000127077 0.9
2.000301436 0.7
3.000456379 0.0
v2: Change from DivideBy to MetricExpr
v3: Use expr__ prefix. Support more than one other event.
v4: Update description

Output the metric expr in perf list when --debug is specified, so that the user
can check the formula.
Before:
% perf list
...

[Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit:
uncore_imc]
uncore_imc_2/event=0x85/
After:
% perf list --debug
...
unc_m_power_channel_ppd
[Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit:
uncore_imc]
Perf: uncore_imc_2/event=0x85/ MetricExpr: (unc_m_power_channel_ppd / unc_m_clockticks) * 100.

Add support for a new JSON event attribute to name MetricExpr for better output
in perf stat.
If the event has no MetricName it uses the normal event name instead to describe
the metric.

Move the printing of perf expressions and internal events to a
new clearer --details flag, instead of lumping it together
with other debug options in --debug. This makes it clearer
to use.

why do use evsel_list instead of perf_evsel__cpus(counter),
which is in the original/removed code?
this patch is about adding collect_data.. if you want to
choose this part, please make it clear in separate patch

* [PATCH 05/13] perf, tools: Expand PMU events by prefix match
2017-03-20 20:16 Andi Kleen
@ 2017-03-20 20:17 ` Andi Kleen

From: Andi Kleen @ 2017-03-20 20:17 UTC (permalink / raw)

From: Andi Kleen <ak@linux.intel.com>
When the user specifies a pmu directly, expand it automatically
with a prefix match for all available PMUs, similar as we do for
the normal aliases now.
This allows to specify attributes for duplicated boxes quickly.
For example uncore_cbox_{0,6}/.../ can be now specified as uncore_cbox/.../
and it gets automatically expanded for all boxes.
This generally makes it more concise to write uncore specifications, and
also avoids the need to know the exact topology of the system.
Before
% perf stat -a -e uncore_cbox_0/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_1/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_2/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_3/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_4/event=0x35,umask=0x1,filter_opc=0x19C/,\
uncore_cbox_5/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
After
% perf stat -a -e uncore_cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
v2: Handle all bison rules. Move multi add code to separate function.
Handle uncore_ prefix correctly.
v3: Move parse_events_multi_pmu_add to separate patch. Move uncore
prefix check to separate patch.
