Bugs with event parsing, event grouping and metrics causes the
TopdownL1 metricgroup to crash the perf command. Temporarily disable
the group if no events/metrics are spcecified.

Division by zero causes expression parsing to fail and no metric to be
generated. This can mean for short running benchmarks metrics are not
shown. Change the behavior to make the value nan, which gets shown like:

Perf stat with no arguments will use default events and metrics. These
events may fail to open even with kernel and hypervisor disabled. When
these fail then the permissions error appears even though they were
implicitly selected. This is particularly a problem with the automatic
selection of the TopdownL1 metric group on certain architectures like
Skylake:
'''
$ perf stat true
Error:
Access to performance monitoring and observability operations is limited.
Consider adjusting /proc/sys/kernel/perf_event_paranoid setting to open
access to performance monitoring and observability operations for processes
without CAP_PERFMON, CAP_SYS_PTRACE or CAP_SYS_ADMIN Linux capability.
More information can be found at 'Perf events and tool security' document:
https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html
perf_event_paranoid setting is 2:
-1: Allow use of (almost) all events by all users
Ignore mlock limit after perf_event_mlock_kb without CAP_IPC_LOCK
>= 0: Disallow raw and ftrace function tracepoint access
>= 1: Disallow CPU event access
>= 2: Disallow kernel profiling
To make the adjusted perf_event_paranoid setting permanent preserve it
in /etc/sysctl.conf (e.g. kernel.perf_event_paranoid = <setting>)
'''
This patch adds skippable evsels that when they fail to open won't
cause termination and will appear as "<not supported>" in output. The
TopdownL1 events, from the metric group, are marked as skippable. This
turns the failure above to:
'''

Which branch is this patch series based on?
I still cannot get the same output as the examples.
I'm using the latest perf-tools-next (The latest commit ID is
5d27a645f609 ("perf tracepoint: Fix memory leak in is_valid_tracepoint()")).
I only applied patch 2 and patch 3, since the patch 1 is already merged.
It's a single socket Cascade Lake. with kernel 5.19-8.
$ uname -r
5.19.8-100.fc35.x86_64
As you can see, all the topdown related events are displayed twice.

The events are displayed twice as there are 2 groups of events. This
is changed by:
https://lore.kernel.org/lkml/20230429053506.1962559-5-irogers@google.com/
where the events are no longer grouped.

The reason nothing is counted is that all the metrics are trying to
share groups with the event INT_MISC.RECOVERY_CYCLES_ANY in them,
which means the whole group ends up being not supported. Again, the
patch above that removes the groups for TopdownL1 and TopdownL2, as
requested by Weilin, will address the issue.

The trick seems don't work on a hybrid machine. I still got the

For hybrid the rest of the patch series is necessary, ie the patches
beyond what's for 6.4, which I take from the output (ie not a crash)
you are looking at. As multiple groups are in play then it looks like
the atom events are on >1 PMU which can happen as the x86 code special
cases events with topdown in their name. Some fixes in the series for
this are:
https://lore.kernel.org/lkml/20230429053506.1962559-6-irogers@google.com/
https://lore.kernel.org/lkml/20230429053506.1962559-40-irogers@google.com/
and related:
https://lore.kernel.org/lkml/20230429053506.1962559-19-irogers@google.com/
and so fixing this requires some detective work.
I don't think it should be a requirement for the series that all
hybrid bugs are fixed - especially given the complaints against the
length of the series as-is.
Thanks,
Ian

I applied all the patches of the series when I did the test on hybrid.
The above patches don't help.

I agree especially considering the metrics have been broken on the
hybrid for a while.
I just want to do a complete test and understand what is going to fixed
and what hasn't.

Some metric groups have metrics that don't have fully overlapping
events, meaning that the group's events become unique event groups
that may need to multiplex with each other. This can be particularly
unfortunate when the groups wouldn't need to multiplex because there
are sufficient hardware counters.
Add a flag so that if recording a metric group then the metrics within
the group needn't use groups for their events. The flag is added to
Intel TopdownL1 and TopdownL2 metrics.

The pmu_group_name by default returns "cpu" which on non-hybrid/ARM
means that ungrouped software, and hardware events are all going to
sort by the original insertion index. However, on hybrid and ARM
wildcard expansion may mean the PMU name is set and events will be
unnecessarily reordered - triggering the reordering warning.

Previously these constraints were disabled as they contained topdown
events. Since:
https://lore.kernel.org/all/20230312021543.3060328-9-irogers@google.com/
the topdown events are correctly grouped even if no group exists.
This change was created by PR:

Previously these constraints were disabled as they contained topdown
events. Since:
https://lore.kernel.org/all/20230312021543.3060328-9-irogers@google.com/
the topdown events are correctly grouped even if no group exists.

Previously these constraints were disabled as they contained topdown
events. Since:
https://lore.kernel.org/all/20230312021543.3060328-9-irogers@google.com/
the topdown events are correctly grouped even if no group exists.
This change was created by PR:

'pmus' list might be empty and, if so, we need to fill it first with:
if (list_empty(&pmus))
perf_pmu__scan(NULL);
before iterating over it. Other option is to add this code to
perf_pmus__for_each_pmu() macro itself.
With that, the test fails for me:
$ sudo ./perf test 6
6: Parse event definition strings :
6.1: Test event parsing : Ok
6.2: Test parsing of "hybrid" CPU events : Skip (not hybrid)

combine_test_results(ret, TEST_OK); probably? Since many pmus don't expose
events via sysfs.

Thanks Ravi! The following looks to address the issues and I'll add it to v4.

This should be strcmp(evsel->pmu_name, "cpu"). Or we could drop the
assert. I'll try to keep what's covered currently by the test while
extending the PMUs.

Rather than skip all tests in test__events_pmu if PMU cpu isn't
present, use the per-test valid test. This allows the running of
software PMU tests on hybrid and arm systems.

Add helper to test the config of an evsel. Mask the config so that
high-bits containing the PMU type, which isn't constant for hybrid,
are ignored.

Extended 'type' via 'config' is applicable only to HW and HW_CACHE types.
I think we should not apply test_config() for other types. Even if they
are ineffective in these tests (because we are not setting upper bits),
they are semantically wrong IMO.
In fact, AMD EventSelect is 12 bits and upper 4 bits are located at 35:32
in PerfEvtSel register. So for RAW events, upper bits MUST NOT be ignored.

Thanks Ravi, this is important and I'll update the tests as you
suggest. I'd been iterating on this, which is why the test is this
way. We have two parsing cases, one where the type is explicitly given
like:
$ perf stat -e '4:0xC0' true
and another where the raw config is wildcard applied like:
$ perf stat -e 'rC0' true
The question is which PMUs should the 0xC0 raw event be opened on? The
answer in the code is to ignore all PMUs that aren't the "core" PMUs,
so cpu, cpu_atom, cpu_core, armv8... This matches existing behavior
but it wasn't clear to me that this was intentional. I think in the
future the wildcard application can be made more efficient to ignore
unnecessary PMUs and avoid the sysfs scan. Something that is a bit of
an issue in the event parsing is what exactly should be applied by
wildcard matching and there are inconsistencies.
Thanks,
Ian

"L1-dcache-misses/name=cachepmu/". Don't just check that the name is
set correctly, also validate the rest of the perf_event_attr for
L1-dcache-misses.

Opening hardware names and a legacy cache event on a hybrid PMU opens
it on each PMU. Parsing and checking indexes fails, as the parsed
index is double the expected. Avoid checking the index by just
comparing the names immediately after the parse.
This change removes hard coded hybrid logic and removes assumptions
about the expansion of an event. On hybrid the PMUs may or may not
support an event and so using a distance isn't a consistent solution.

Set attr.type to PMU type early so that later terms can override the
value. Setting the value in perf_pmu__config means that earlier steps,
like config_term_pmu, can override the value.

Change add_event to always set pmu_name when possible as not all code
checks both pmu->name and evsel->pmu_name, for example,
uniquify_counter in stat-display.c.

The strlist in print_hwcache_events holds the event names as they are
generated, and then it is iterated and printed. This is unnecessary
and each event can just be printed as it is processed.
Rename the variable i to res, to be more intention revealing and
consistent with other code.

The event parser needs to handle two special cases:
1) legacy events like L1-dcache-load-miss. These event names don't
appear in json or sysfs, and lookup tables are used for the config
value.
2) raw events where 'r0xead' is the same as 'read' unless the PMU has
an event called 'read' in which case the event has priority.
The previous parser to handle these cases would scan all PMUs for
components of event names. These components would then be used to
classify in the lexer whether the token should be part of a legacy
event, a raw event or an event. The grammar would handle legacy event
tokens or recombining the tokens back into a regular event name. The
code wasn't PMU specific and had issues around events like AMD's
branch-brs that would fail to parse as it expects brs to be a suffix
on a legacy event style name:
$ perf stat -e branch-brs true
event syntax error: 'branch-brs'
\___ parser error
This change removes processing all PMUs by using the lexer in the form
of a regular expression matcher. The lexer will return the token for
the longest matched sequence of characters, and in the event of a tie
the first. The legacy events are a fixed number of regular
expressions, and by matching these before a name token its possible to
generate an accurate legacy event token with everything else matching
as a name. Because of the lexer change the handling of hyphens in the
grammar can be removed as hyphens just become a part of the name.
To handle raw events and terms the parser is changed to defer trying
to evaluate whether something is a raw event until the PMU is known in
the grammar. Once the PMU is known, the events of the PMU can be
scanned for the 'read' style problem. A new term type is added for
these raw terms, used to enable deferring the evaluation.
While this change is large, it has stats of:
170 insertions(+), 436 deletions(-)
the bulk of the change is deleting the old approach. It isn't possible
to break apart the code added due to the dependencies on how the parts
of the parsing work.

If we have a group of {cycles,faults} then we need the faults software
event to appear to be on the same PMU as cycles so that we don't split
the group in parse_events__sort_events_and_fix_groups. This case is
relatively easy as cycles is the leader and will have a PMU name. In
the reverse case, {faults,cycles} we still need faults to appear to
have the PMU name of cycles but the old behavior is just to return
"cpu". For hybrid this fails as cycles will be on "cpu_core" or
"cpu_atom", causing faults to be split into a different group.
Change the behavior for software events so that the whole group is
searched for the named PMU.

Don't assume evlist order. Switch to a loop rather than depend on
evlist order for raw events test.
Update hybrid event expectations. Previous values were based on
parsing legacy hardware events from sysfs, update to the correct PMU
specific legacy values.

Allow a legacy cache event to be both, for example,
"L1-dcache-load-miss" and "cpu/L1-dcache-load-miss/" by introducing a
new legacy cache term type. The term type is processed in
config_term_pmu, setting both the type in perf_event_attr and the
config. The code to determine the config is factored out of
parse_events_add_cache and shared. If the PMU doesn't support legacy
events, currently just core/hybrid PMUs do, then the term is treated
like a PE_NAME term - as before. If only terms are being parsed, such
as for perf_pmu__new_alias, then the PE_LEGACY_CACHE token is always
parsed as PE_NAME.

It is inconsistent that "perf stat -e instructions-retired" wildcard
opens on all PMUs while legacy cache events like "perf stat -e
L1-dcache-load-miss" do not. A behavior introduced by hybrid is that a
legacy cache event like L1-dcache-load-miss should wildcard open on
all hybrid PMUs. Previously hybrid would call to is_event_supported
for each PMU, a failure of which results in the event not being
added. This isn't done in this case as the parser should just create
perf_event_attr and the later open should fail, or the counter give
"<not counted>". If this wants to be avoided then the PMU can be named
with the event.

This statement is bit confusing. Can you please explain how SW pmus can
open cache events.

Yep, but I think the commit message should call it out, so I'll change
it in v4. When we have an alias the event type descriptor isn't shown,
this is pre-existing perf list behavior but I think we may want to
tweak it as I like the event type descriptor.

If the type is PERF_TYPE_HW_CACHE (3) and the extended type is
PERF_TYPE_SOFTWARE (1) then this yields the encoding '3:0x100000000'
which will succeed perf_event_open:
```
$ perf stat -vv -e '3:0x100000000' true
Using CPUID GenuineIntel-6-8D-1
intel_pt default config: tsc,mtc,mtc_period=3,psb_period=3,pt,branch
Control descriptor is not initialized
------------------------------------------------------------
perf_event_attr:
type 3
size 128
config 0x100000000
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
enable_on_exec 1
exclude_guest 1
------------------------------------------------------------
sys_perf_event_open: pid 2128955 cpu -1 group_fd -1 flags 0x8 = 3
3:0x100000000: -1: 265630 261923 261923
3:0x100000000: 265630 261923 261923
Performance counter stats for 'true':
265,630 3:0x100000000
0.000844251 seconds time elapsed
0.000911000 seconds user
0.000000000 seconds sys
```
I agree this isn't expected, but if I don't exclude the PMU type the
print events will list it as an alias. I'll try to improve the comment
in v4.
Thanks,
Ian

Legacy raw events like r1a open as PERF_TYPE_RAW on non-hybrid systems
and on each hybrid PMU on hybrid systems. Rather than iterate hybrid
PMUs add a perf_pmu__supports_wildcard_numeric function that says when
a numeric event should be opened upon it. If the parsed event
specifies the type of the PMU then don't wildcard match PMUs, use the
specified PMU type.

The event parser no longer needs to recurse in case of a legacy cache

Cc: Ian Rogers
Rather than limit the --cputype argument for "perf list" and "perf
stat" to hybrid PMUs of just cpu_atom and cpu_core, allow any PMU.
Note, that if cpu_atom isn't mounted but a filter of cpu_atom is
requested, then this will now fail. As such a filter would never
succeed, no events can come from that unmounted PMU, then this
behavior could never have been useful and failing is clearer.

I've couple of doubts:
1. Can you please explain intention to do this esp for perf list. Since, IIUC,
`perf list --unit` option provide the same functionality.
2. Since we are already specifying pmu name for non-standerd/arch-specific
events like `pmu/attributes/`, I'm not sure where `perf stat --cputype=pmu`
is useful. Can you please explain perf stat usability aspect for non-hybrid
pmus.
3. What am I missing here:
$ sudo ./perf stat --cputype=amd_df -e amd_l3/event=0x4,umask=0xff/ -C 0 -- sleep 1
Performance counter stats for 'CPU(s) 0':

I'm hitting a segfault if I use non-existing pmu:
$ sudo ./perf list --cputype=random

man perf-list does not describe --cputype. I think we should add it as part
of this patch?
Similarly, man perf-stat also needs to be updated.

Any specific reason to ignore "uncore_"? IMHO, ignoring prefix of some
pmus and not of others is bit confusing for naive user.

I agree with you. The option already exists and I think we should just
move this option to being deprecated/hidden:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/lib/subcmd/parse-options.h#n46

Completely agreed. This patch series is trying to remove the
duplicated code introduced by the hybrid changes. In this case I
didn't want to remove an option, and potentially break users of that
option, as part of fixing things up. A lot of what you are saying here
I added as comments to the original patch series.

The cputype applies to wildcard-ed events. So on hybrid:
$ perf stat -e cycles true
will open cycles on cpu_atom and cpu_core, the
parse_events__filter_pmu function is used skip PMUs based on cputype.
> 3. Also, IMHO, using --cputype option to specify _pmu name_ is bit odd.
Right, when the "feature" was added I would have preferred it as PMU
rather than CPU.

Will fix in v4. The warning should be fatal/exit rather than try to
read the PMU's name.

Ok, these changes are just keeping existing functionality. I don't
disagree with making these changes but I think we can follow up with
them. Or probably just deprecate the option.

It is trying to be consistent with the event parser:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/util/parse-events.y#n326
where uncore is consumed. Fun fact, as numbers are consumed after a
PMU name and the underscore is optional, i915 as a PMU can be matched
in parsing with a PMU name of just "i".

Ian

Cc: Ian Rogers
An event like "cpu/instructions/" typically parses due to there being
a sysfs event called instructions. On hybrid recursive parsing means
that the hardware event is encoded in the attribute, with the PMU
being placed in the high bits of the config:
'''
$ perf stat -vv -e 'cpu_core/cycles/' true
...
------------------------------------------------------------
perf_event_attr:
size 136
config 0x400000000
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
enable_on_exec 1
exclude_guest 1
------------------------------------------------------------
'''
Make this behavior the default by adding a new term type and token for
hardware events. The token gathers both the numeric config and the
parsed name, so that if the token appears like "cycles/name=cycles/"
then the token can be handled like a name. The numeric value isn't
sufficient to distinguish say "cpu-cycles" from "cycles".
Extend the parse-events test so that all current non-PMU hardware
parsing tests, also test with the PMU cpu - more than half the change.

These are generic terms and thus can be added to _any_ pmus. Ex:
Before:
```
$ sudo ./perf stat -e amd_l3/cycles/ -C 0 -- sleep 1
event syntax error: 'amd_l3/cycles/'
\___ unknown term 'cycles' for pmu 'amd_l3'
```
After:
```
$ sudo ./perf stat -e amd_l3/cycles/ -C 0 -vv -- sleep 1
Control descriptor is not initialized
------------------------------------------------------------
perf_event_attr:
size 136
config 0xb00000000
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
exclude_guest 1
------------------------------------------------------------
sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8
sys_perf_event_open failed, error -2
Warning:
amd_l3/cycles/ event is not supported by the kernel.
failed to read counter amd_l3/cycles/
Performance counter stats for 'CPU(s) 0':
<not supported> amd_l3/cycles/
1.059391819 seconds time elapsed
```
Here `type=0` which means perf is trying to open event on HW pmu instead
of amd_l3//. `config` is 0xb00000000 where 0xb is amd_l3 pmu type:
$ cat /sys/bus/event_source/devices/amd_l3/type
11
Not sure if this is expected behavior.

I agree this is definitely a change, I'm not sure what we can do to
handle this better. Firstly, let's not be overly negative, the code
fixes it so that "branch-brs" (an AMD sysfs event) is now a valid
event name rather than a parse error. For the example above we have
the case of an unsupported event now not giving a parse error, only
possible as all PMUs were scanned, but giving an open error as the
event name matches in the list of hardware events but the extended
type encoding of the PMU yields a PMU that can't handle it.
I think parsing should be concerned with taking information to yield a
struct perf_event_attr. When it gets into the game of testing PMUs for
support then we easily get test regressions, as the test system may
lack the PMUs that are part of the test. We also get issues on hybrid
like PERF_TYPE_HW_CACHE events being supported by one PMU and not the
other. The existing hybrid behavior is to silently skip the events
that aren't supported - tested with a perf_event_open. The behavior
after these patches is to open the event on both PMUs but display not
supported/counted generally on the atom PMU. So the coding decision
there was to say parsing and opening are separate stages, and the
correct place to fail was in the open.
We could change the event parsing for this case, have different parser
notions of core PMU and every PMU, then only allow the hardware events
on the core PMU. This would require hard coding a core PMU list into
the parser and I'm not keen on that.
Thanks,
Ian

Avoid the parser error:
'''
$ perf stat -e 'cycles/name=name/' true
event syntax error: 'cycles/name=name/'
\___ parser error
'''
by turning the term back to a string if it is on the right. Add PMU
and generic parsing tests.

On hybrid systems the topdown events don't share a fixed counter on
the atom core, so they don't require the sorting the perf metric
supporting PMUs do.

Cc: Ian Rogers
Fix the metrics tma_memory_bound on alderlake cpu_core and
tma_microcode_sequencer on alderlake cpu_atom, where metrics had be
rewritten across PMUs. Fix MEM_BOUND_STALLS_AT_RET_CORRECTION which is
an aux metric but lacks a hash prefix. Add PMU prefixes for
cpu_core/cpu_atom events to avoid wildcard opening the events.

Don't rewrite metrics across PMUs as the result events likely won't be
found. Identify metrics with a pair of PMU name and metric name.

Ids/events from a metric are turned into an event string and parsed;
setup_metric_events matches the id back to the parsed evsel. With
hybrid the same event may exist on both PMUs with the same name and be
being used by metrics at the same time. A metric on cpu_core therefore
shouldn't match against evsels on cpu_atom, or the metric will compute
the wrong value. Make the matching sensitive to the PMU being parsed.

Now that hybrid bugs are fixed sufficient to run TopdownL1 metrics,
don't implicitly disable them for hybrid.

The metrics and metricgroups tests are failed on a hybrid machine.
Seems we need the no group trick for more metrics?

This is expected. Metrics test fails on Icelake, metricgroups doesn't
validate output but I can expect metricgroups like "transaction" to
have issues. We want to have better tests and this comes under what
we're hoping to achieve with the Valkyrie project.
