There are some syntactical mistakes in the json files for the Cortex A76 N1 (Neoverse N1). This was obstructing parsing from an external tool. This patch fixes the erroneous placement of commas causing the problems. Reviewed-by:

Previously find_evsel_group was trying to share events while mark-sweeping to eliminate unused events, this was complicated and had issues around uncore events and grouped sharing. This was further complicated by the event string being created while metrics and metric groups were being added, with the string affecting the evlist order. This change moves deduplication before event parsing. Ungrouped events are placed in a single combined set. Groups are checked to see if an earlier (larger) group can support their events. As the deduplication and sharing detection is done on metric IDs before parsing, wildcard expansion problems with uncore events are avoided. Overall the code is simpler while working better. An example of failing to deduplicate can be seen with a list of metrics like the following, where in the after case multiplexing has been avoided: Before: $ perf stat -M Bad_Speculation,Backend_Bound,Frontend_Bound,Retiring -a sleep 2 Performance counter stats for 'system wide': 959,620,872 uops_issued.any # 0.06 Bad_Speculation (50.03%) 2,163,072,261 cycles # 0.09 Retiring (50.03%) 735,827,436 uops_retired.retire_slots (50.03%) 74,676,484 int_misc.recovery_cycles (50.03%) 987,062,794 uops_issued.any # 0.50 Backend_Bound (49.97%) 2,203,734,187 cycles # 0.35 Frontend_Bound (49.97%) 3,085,016,091 idq_uops_not_delivered.core (49.97%) 758,599,232 uops_retired.retire_slots (49.97%) 75,807,526 int_misc.recovery_cycles (49.97%) 2.002103760 seconds time elapsed After: $ sudo perf stat -M Bad_Speculation,Backend_Bound,Frontend_Bound,Retiring -a sleep 2 Performance counter stats for 'system wide': 769,694,676 uops_issued.any # 0.08 Bad_Speculation # 0.41 Backend_Bound 1,087,548,633 cycles # 0.38 Frontend_Bound # 0.14 Retiring 1,642,085,777 idq_uops_not_delivered.core 603,112,590 uops_retired.retire_slots 43,787,854 int_misc.recovery_cycles 2.003844383 seconds time elapsed Signed-off-by: -

For a metric like IPC a group of events like {instructions,cycles}:W would be formed. If the events names were changed in parsing then the metric expression parser would fail to find them. This change makes the event encoding be something like: {instructions/metric-id=instructions/, cycles/metric-id=cycles/} and then uses the evsel's stable metric-id value to locate the events. This fixes the case that an event is restricted to user because of the paranoia setting: $ echo 2 > /proc/sys/kernel/perf_event_paranoid $ perf stat -M IPC /bin/true Performance counter stats for '/bin/true': 150,298 inst_retired.any:u # 0.77 IPC 187,095 cpu_clk_unhalted.thread:u 0.002042731 seconds time elapsed 0.000000000 seconds user 0.002377000 seconds sys Adding the metric-id as a qualifier has a complication in that qualifiers will become embedded in qualifiers. For example, msr/tsc/ could become msr/tsc,metric-id=msr/tsc// which will fail parse-events. To solve this problem the metric is encoded and decoded for the metric-id with !<num> standing in for an encoded value. Previously ! wasn't parsed. With this msr/tsc/ becomes msr/tsc,metric-id=msr!3tsc!3/ The metric expression parser is changed so that @ isn't changed to /, instead this is done when the ID is encoded for parse events. metricgroup__add_metric_non_group() and metricgroup__add_metric_weak_group() need to inject the metric-id qualifier, so to avoid repetition they are merged into a single metricgroup__build_event_string with error codes more rigorously checked. stat-shadow's prepare_metric() uses the metric-id to match the metricgroup code. As "metric-id=..." is added to all events, it is adding during testing with the fake PMU. This complicates pmu_str_check code as PE_PMU_EVENT_FAKE won't match as part of a configuration. The testing fake PMU case is fixed so that if a known qualifier with an ! is parsed then it isn't reported as a fake PMU. This is sufficient to pass all testing but it and the original mechanism are somewhat brittle. Signed-off-by: -

An event like inst_retired.any on an Intel skylake is found in the pmu-events code created from the pipeline event JSON. The event is an alias for cpu/event=0xc0,period=2000003/ and parse-events recognizes the event with the token PE_KERNEL_PMU_EVENT. The parser doesn't currently allow extra configuration on such events, except for modifiers, so: $ perf stat -e inst_retired.any// /bin/true event syntax error: 'inst_retired.any//' \___ parser error Run 'perf list' for a list of valid events Usage: perf stat [<options>] [<command>] -e, --event <event> event selector. use 'perf list' to list available events This patch adds configuration to these events which can be useful for a number of parameters like name and call-graph: $ sudo perf record -e inst_retired.any/call-graph=lbr/ -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.856 MB perf.data (44 samples) ] It is necessary for the metric code so that we may add metric-id values to these events before they are parsed.

Add a new "metric-id" term to events so that metric parsing can set an ID that can be reliably looked up. Metric parsing currently will turn a metric like "instructions/cycles" into a parse events string of "{instructions,cycles}:W". However, parse-events may change "instructions" into "instructions:u" if perf_event_paranoid=2. When this happens expr__resolve_id currently fails as stat-shadow adds the ID "instructions:u" to match with the counter value and the metric tries to look up the ID just "instructions". A later patch will use the new term. An example of the current problem: $ echo -1 > /proc/sys/kernel/perf_event_paranoid $ perf stat -M IPC /bin/true Performance counter stats for '/bin/true': 1,217,161 inst_retired.any # 0.97 IPC 1,250,389 cpu_clk_unhalted.thread 0.002064773 seconds time elapsed 0.002378000 seconds user 0.000000000 seconds sys $ echo 2 > /proc/sys/kernel/perf_event_paranoid $ perf stat -M IPC /bin/true Performance counter stats for '/bin/true': 150,298 inst_retired.any:u # nan IPC 187,095 cpu_clk_unhalted.thread:u 0.002042731 seconds time elapsed 0.000000000 seconds user 0.002377000 seconds sys Note: nan IPC is printed as an effect of "perf metric: Use NAN for missing event IDs." but earlier versions of perf just fail with a parse error and display no value.

Modify resolution. Rather than resolving a list of metrics, resolve a metric immediately after it is added. This simplifies knowing the root of the metric's tree so that IDs may be associated with it. A bug in the current implementation is that all the IDs were placed on the first metric in a metric group. Rather than maintain data on IDs' parents to detect cycles, maintain a list of visited metrics and detect cycles if the same metric is visited twice. Only place the root metric onto the list of metrics. Signed-off-by:

If a metric references other metrics then the same other metrics may be referenced more than once, but the events and metric ref are only needed once. An example of this is in tests/parse-metric.c where DCache_L2_Hits references the metric DCache_L2_All_Hits twice, once directly and once through DCache_L2_All. Signed-off-by:

The runtime value is needed when recursively parsing metrics, currently a value of 1 is passed which is incorrect. Rather than add more arguments to the bison parser, add runtime to the context. Fix call sites not to pass a value. The runtime value is defaulted to 0, which is arbitrary. In some places this replaces a value of 1, which was also arbitrary. This shouldn't affect anything other than PPC. The use of 0 or 1 shouldn't matter as a proper runtime value would be needed in a case that it did matter. Signed-off-by:

Pull netfslib, cachefiles and afs fixes from David Howells: - Fix another couple of oopses in cachefiles tracing stemming from the possibility of passing in a NULL object pointer - Fix netfs_clear_unread() to set READ on the iov_iter so that source it is passed to doesn't do the wrong thing (some drivers look at the flag on iov_iter rather than other available information to determine the direction) - Fix afs_launder_page() to write back at the correct file position on the server so as not to corrupt data * tag 'misc-fixes-20211007' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Fix afs_launder_page() to set correct start file position netfs: Fix READ/WRITE confusion when calling iov_iter_xarray() cachefiles: Fix oops with cachefiles_cull() due to NULL object
