Default events are marked skippable. Checking skippable first means
retrying and adding modifiers like exclude kernel isn't
performed. Push the skippable checking after fallbacks are tried and
avoid warning multiple times for the event.

The term list when adding an event to a PMU is expected to have the
event name for the alias lookup. Also, set found_supported so that
-EINVAL isn't returned.

Scan the software PMU first rather than last as it is the least likely
to fail the probe. Specifying the software PMU by name was enabled by
commit 9957d8c801fe ("perf jevents: Add common software event
json"). For hardware events, add core PMU names when getting events to
probe so that not all PMUs are scanned. For example, when legacy
events support wildcards and for the event "cycles:u" on x86, we want
to only scan the "cpu" PMU and not all uncore PMUs for the event too.

Without a PMU perf matches an event against any PMU with the
event. Unfortunately some PMU drivers advertise a "cycles" event which
is typically just a core event. To make perf's behavior consistent,
just look up default events with their designated PMU types.

Whilst for many tools it is an expected behavior that failure to open
a perf event is a failure, ARM decided to name PMU events the same as
legacy events and then failed to rename such events on a server uncore
SLC PMU. As perf's default behavior when no PMU is specified is to
open the event on all PMUs that advertise/"have" the event, this
yielded failures when trying to make the priority of legacy and
sysfs/json events uniform - something requested by RISC-V and ARM. A
legacy event user on ARM hardware may find their event opened on an
uncore PMU which for perf record will fail. Arnaldo suggested skipping
such events which this patch implements. Rather than have the skipping
conditional on running on ARM, the skipping is done on all
architectures as such a fundamental behavioral difference could lead
to problems with tools built/depending on perf.
An example of perf record failing to open events on x86 is:
```
$ perf record -e data_read,cycles,LLC-prefetch-read -a sleep 0.1
Error:
Failure to open event 'data_read' on PMU 'uncore_imc_free_running_0' which will be removed.
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (data_read).
"dmesg | grep -i perf" may provide additional information.
Error:

The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (data_read).

Error:

```
As an evlist may have dummy events that open when all command line
events fail we ignore dummy events when detecting if at least some
events open. This still permits the dummy event on its own to be used
as a permission check:
```
$ perf record -e dummy true

but allows failure when a dummy event is implicilty inserted or when
there are insufficient permissions to open it:
```
$ perf record -e LLC-prefetch-read -a true
Error:
Failure to open event 'LLC-prefetch-read' on PMU 'cpu' which will be removed.
The LLC-prefetch-read event is not supported.
Error:
Failure to open any events for recording
```
As the first parsed event in an evlist is marked as tracking, removing
this event can remove tracking from the evlist, removing mmap events
and breaking symbolization. To avoid this, if a tracking event is
removed then the next event has tracking added.
The issue with legacy events is that on RISC-V they want the driver to
not have mappings from legacy to non-legacy config encodings for each
vendor/model due to size, complexity and difficulty to update. It was
reported that on ARM Apple-M? CPUs the legacy mapping in the driver
was broken and the sysfs/json events should always take precedent,
however, it isn't clear this is still the case. It is the case that
without working around this issue a legacy event like cycles without a
PMU can encode differently than when specified with a PMU - the
non-PMU version favoring legacy encodings, the PMU one avoiding legacy
encodings. Legacy events are also case sensitive while sysfs/json
events are not.
The patch removes events and then adjusts the idx value for each
evsel. This is done so that the dense xyarrays used for file
descriptors, etc. don't contain broken entries.
On ARM it could be common following this change to see a lot of
warnings for the cycles event due to many ARM PMUs advertising the
cycles event (ARM inconsistently have events bus_cycles and then
cycles implying CPU cycles, they also sometimes have a cpu_cycles
event). As cycles is a popular event, avoid potentially spamming users
with error messages on ARM when there are multiple cycles events in
the evlist, the error is still shown when verbose is enabled.
Prior versions without adding the tracking data and not warning for
cycles on ARM was:

The jevents command expects all json files to be organized under a
single directory. When generating json files from scripts (to reduce
laborious copy and paste in the json) we don't want to generate the
json into the source directory if there is an OUTPUT directory
specified. This change adds a GEN_JSON for this case where the
GEN_JSON copies the JSON files to OUTPUT, only when OUTPUT is
specified. The Makefile.perf clean code is updated to clean up this
directory when present.
This patch is part of:
https://lore.kernel.org/lkml/20240926173554.404411-12-irogers@google.com/
which was similarly adding support for generating json in scripts for
the consumption of jevents.py.

When an event/alias is created for a PMU the terms are eagerly parsed
using parse_events_terms. For a command like perf stat or perf record,
the particular event/alias will be found, the terms parsed, the
terms cloned for use in the event parsing, and then the terms used to
configure the perf_event_attr. Events/aliases may be eagerly loaded,
such as from sysfs or in perf list, in which case the aliases terms
will be little or never used. To avoid redundant work, to avoid
cloning, and to reduce memory overhead, hold the terms for an event as
a string until they need handling as a term list. This may introduce
duplicate parsing if an event is repeated in a list, but this
situation is expected to be uncommon.
Measuring the number of instructions before and after with a sysfs
event and perf stat, there is a minor reduction in the number of
instructions executed by 0.3%.

Now the events file isn't directly parsed from a FILE but stored in a
string prior to parsing, remove the FILE argument to the associated
scanner functions as they only ever pass NULL.

The FILE argument was necessary for the scanner but now that
functionality is not being used we can switch to just using
io__getline which should cut down on stdio buffer usage.

Cc: Thomas Richter
Add the PMU terms legacy-hardware-config and
legacy-cache-config. These terms are similar to the config term in
that their values are assigned to the perf_event_attr config
value. They differ in that the PMU type is switched to be either
PERF_TYPE_HARDWARE or PERF_TYPE_HW_CACHE, and the PMU type is moved
into the extended type information of the config value. This will
allow later patches to add legacy events to json.
An example use of the terms is in the following:
```
$ perf stat -vv -e 'cpu/legacy-hardware-config=1/,cpu/legacy-cache-config=0x10001/' true
Using CPUID GenuineIntel-6-8D-1

Add json LegacyConfigCode and LegacyCacheCode values that translate to
legacy-hardware-config and legacy-cache-config event terms
respectively.
Add perf_pmu__default_core_events_table as a means to find a
default_core event table that will later contain legacy events.
In situations like hypervisors it is more likely that tables will be
NULL. Rather than testing in the calling PMU code, early exit in the
pmu-event.c routines.

Add support to finding/adding events from the default_core event
table. If an event already exists from sysfs/json then the
default_core configuration is saved in the legacy_terms string. Lazily
use the legacy_terms string to set a legacy hardware or cache event as
deprecated if the core PMU doesn't support it. Use the legacy terms
string to set the alternate_hw_config, avoiding the value needing to
be passed from the parse_events parser.

Cc: Thomas Richter
The legacy-hardware.json is added containing hardware events similarly
to the software.json file. A difference is that for the software PMU
the name is known and matches sysfs. In the legacy-hardware.json no
Unit/PMU is specified for the events meaning default_core is used and
the events will appear for all core PMUs.
There are potentially 1216 legacy cache events, rather than list them
in a json file add a make_legacy_cache.py helper to generate them.
By using json for legacy hardware and cache events: descriptions of
the events can be added; events can be marked as deprecated, such as
those misleadingly named l2 (deprecated is also used to mark all
events that weren't previously displayed in perf list); and the name
lookup becomes case insensitive.
The C string encoding all the perf events and metrics is increased in
size by 123,499 bytes which will increase the perf binary size. Later
changes will remove hard coded event parsing for legacy hardware and
cache events, turning parsing overhead into a binary search during
event lookup.
That event descriptions are based off of those in perf_event_open man
page, credit to Vince Weaver <vincent.weaver@maine.edu>.

Now legacy hardware events are in json there's no need for a specific
printing routine that previously served for both hardware and software
events. The associated event_symbols_hw is also removed. To support
the previous filtered version use an event glob of "legacy hardware"
which matches the topic of the json events.

Now that legacy hardware and cache events are in json, having the
lexer match the specific event is no longer necessary and generic PMU
parsing can take place. Because of this remove the specific term
parsing, event adding, and passing of alternate_hw_config which was
now always PERF_COUNT_HW_MAX.
This mirrors a similar change for software events in commit 6e9fa4131abb
("perf parse-events: Remove non-json software events").
With no hard coded legacy hardware or cache events the wild card, case
insensitivity, etc. is consistent for events. This does, however, mean
events like cycles will wild card against all PMUs. A change does the
same was originally posted and merged from:
https://lore.kernel.org/r/20240416061533.921723-10-irogers@google.com
and reverted by Linus in commit 4f1b067359ac ("Revert "perf
parse-events: Prefer sysfs/JSON hardware events over legacy"") due to
his dislike for the cycles behavior on ARM. Earlier patches in this
series make perf record event opening failures non-fatal and hide the
cycles event's failure to open on ARM in perf record, so it is
expected the behavior will now be transparent in perf record. perf
stat with a cycles event will wildcard open the event on all PMUs. As
cycles is a "default event", the perf stat behavior for default events
was updated to only open them on core/software PMUs.
The change to support legacy events with PMUs was done to clean up
Intel's hybrid PMU implementation. Having sysfs/json events with
increased priority to legacy was requested by Mark Rutland
<mark.rutland@arm.com> to fix Apple-M PMU issues wrt broken legacy
events on that PMU. It was requested that RISC-V be able to add events
to the perf tool json so the PMU driver didn't need to map legacy
events to config encodings:
https://lore.kernel.org/lkml/20240217005738.3744121-1-atishp@rivosinc.com/
A previous series of patches decreasing legacy hardware event
priorities was posted in:
https://lore.kernel.org/lkml/20250416045117.876775-1-irogers@google.com/
Namhyung Kim <namhyung@kernel.org> mentioned that hardware and
software events can be implemented similarly:

Rather than wildcard matching the cycles event specify only the core
PMUs. This avoids potentially loading unnecessary uncore PMUs.

Ensure both the perf_event_attr and alternate_hw_config are checked in
the match. Don't mask the config if the perf_event_attr isn't a
HARDWARE or HW_CACHE event. Add common early exit cases.

Switch from the test's assert_hw/test_config to the common
evsel__match code that appropriately handles events with both legacy
and sysfs/json encoding.
For tests asserting that a config value matches that placed in the
perf_event_attr just directly compare the config values.

Without a PMU perf matches an event against any PMU with the
event. Unfortunately some PMU drivers advertise a "cycles" event which
is typically just a core event. Switch to using "cpu-cycles" which is
an indentical legacy event but avoids the multiple PMU confusion
introduced by the PMU drivers. Note, on x86 cpu-cycles is also a sysfs
event but cycles isn't.

In the event parse string, switch "cpu" to "default_core" and then
rewrite this to the first core PMU name prior to parsing. This enables
testing with a PMU on hybrid x86 and other systems that don't use
"cpu" for the core PMU name. The name "default_core" is already used
by jevents. Update test expectations to match.

Without a PMU perf matches an event against any PMU with the
event. Unfortunately some PMU drivers advertise a "cycles" event which
is typically just a core event. As tests assume a core event, switch
to use "cpu-cycles" that avoids the overloaded "cycles" event on
troublesome PMUs and is so far not overloaded. Note, on x86 this
changes a legacy event into a sysfs one.

Add TEST_ASSERT_EVLIST to dump the failing evlist in the event of a
failure.
Add the macro to a number of tests not currently checking the evlist
length.

Hi Ian,
Did you drop the change to ignore failures to open events in favour of
switching the default from "cycles" to "cpu-cycles" instead? I'm trying
to follow the changelog but couldn't see it.
In v3 I got <not supported> for the uncore cycles event, but in v6 I get
a complete failure:
-> sudo perf-v3 stat -e cycles -- true
Performance counter stats for 'true':
1732478 cycles
<not supported> arm_cmn_0/cycles/
-> sudo perf-v6 stat -e cycles -- true
Error:
Invalid event (cycles) in per-thread mode, enable system wide with '-
a'.
The verbose output shows that it tries both, but doesn't ignore the
error on arm_cmn_0 anymore:
-> sudo perf-v6 stat -e cycles -vvv -- true

Hi James,
your example is using `perf stat` whilst the behavior to ignore
failing to open events is for `perf record` and added in:
https://lore.kernel.org/lkml/20250923223312.238185-6-irogers@google.com/
Changing the behavior for `perf stat` hasn't been in scope for making
the behavior of legacy events consistent in any patch series. The
whole '<not counted>' vs '<not supported>' vs an early exit is
something where not changing behavior has been the name of the game
for many years due to potential reliance on the behavior.
Fwiw, this series migrates legacy events to json we should be able to
do the same with the legacy hard coded metrics in `perf stat` once it
lands. Removing the hard coded metrics will give better metrics as we
can use event groups, share events between metrics, .. and only
display requested metrics when metrics are requested. My point is that
there is further `perf stat` clean up that this work moves us toward
but at 28 patches already I'd like not to start work on making perf
stat a better place. Getting consensus on what that better place is
given the existing fragmentic behavior will be a challenge, but at
least these days we have some form of tests, albeit they tend to flake
all the time. To solve your problems below where you're specifically
picking an event that can wildcard, give the PMU or use cpu-cycles, or
one of the many other names ARM already has to mean this. Overloading
the event 'cycles' wasn't something introduced in this series and the
fact changing the name hasn't happened in the drivers is really very
frustrating.
Thanks,
Ian

Re v3 vs v6:
v3 series here has no changes to perf stat:
https://lore.kernel.org/lkml/20250828205930.4007284-1-irogers@google.com/
the v6 does change perf stat in the "add_default_events" function:
https://lore.kernel.org/lkml/20250923223312.238185-5-irogers@google.com/
but you are reporting an issue with an event specified, so not using
default events. The evsel changes in v6 are for the evsel__match
function that isn't used during event opening.

I don't see the exact issue here? v3 perf stat reported "<not
supported>" for the uncore event, which is accurate, and continued on
with the working event. Which seemed consistent with the change in perf
record.
What use case would break exactly if we don't do the same for perf stat?
If a user isn't specific about a PMU it should attempt to open wherever
it can, if all fail then exit early.

Maybe there are no direct changes to perf stat, but the user facing
behavior still changes. Now perf record ignores the bad uncore event,
but perf stat doesn't, making it inconsistent. V3 was better in this regard.
I'm not sure if you are saying that you wouldn't expect there to be
_any_ change to perf stat in V3? Or just that perf stat itself wasn't
changed but things that it depends on were? I just want to make sure
I've tested the right thing and we're talking about the same thing.
I double checked and rebuilt 20250828205930.4007284-1-irogers@google.com
(v3) and still see the different behavior in perf stat that I posted above.

I've not argued against the idea, this patch series and many prior
have been put upon to add quirks for the sake of a certain vendor's
PMU drivers having events named the same as legacy events and them
being too belligerent to rename them. I don't want supporting vendor
PMU event naming quirks to cause things to be more complicated than is
absolutely necessary. The key part of this series to me is:
https://lore.kernel.org/lkml/20250923223312.238185-18-irogers@google.com/
that is removing 362 lines of the parsing logic. Doing this but
filling the rest of the code base up with new special cases isn't
achieving the simplicity, consistency, .. that I'm hoping for. It is
bad enough that there is a major change to perf record's behavior in
the series, I expect complaints about this :-(
I'm not sure why you are seeing a difference of behavior between v3
and v6 given the code you are testing didn't change. I'm wondering if
a different change in the tree is the issue. Doing a quick comparison
between v6.12 perf and perf-tools-next running not as root and using
an uncore event I see:
```
$ perf --version
perf version 6.12.35
$ perf stat -e data_read true
Performance counter stats for 'system wide':
<not supported> MiB data_read:u
0.001779459 seconds time elapsed
$ /tmp/perf/perf --version
perf version 6.17.rc6.gd18020cf1e92
$ /tmp/perf/perf stat -e data_read true
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument)
for event (data_read:u).
"dmesg | grep -i perf" may provide additional information.
```
with the behavior with these patches matching that of perf-tools-next.
I'll dig into this but I'm off in the weeds tracking down issues for
the sake of a certain vendor again and failing to land clean up.
Fwiw, I don't think there's any chance of this making it into v6.18
but getting it into perf-tools-next for an eventual v6.19 would mean
we can work through teething issues.
Thanks,
Ian

I sent a fix:
https://lore.kernel.org/linux-perf-users/20251002200604.1792141-2-irogers@google.com/
that makes it so that only if all events are unsupported that perf
stat exits - this is addressing a bunch of latent issues and fixes the
perf-tools-next regression. I don't think there is a difference
between v3 and v6 wrt this behavior, I think you were probably just
cherry-picking the v6 patches onto a newer tree. When those 2 patches
land I can rebase this series on them and drop the first patch of this
series.
Thanks,
Ian

That is true about the cherry picking. I could only apply V3 to
perf-tools and V6 to perf-tools-next, that was just a guess without the
hash in the cover letter.
I did test both unpatched perf-tools and perf-tools-next to confirm that
the original behavior was the same in those. Once I saw it was the same
I assumed the difference was only in the V3 vs V6. But you're right it
could be because of the base.
I'll retest with the fix applied

Yeah the behavior seems good now after testing with that fix applied and
the first patch of this set dropped.
Will wait for the rebase and then do more testing.
