blit_x and blit_y are u32, so fbcon currently cannot support fonts larger than 32x32.

The Retire Latency field is added in the var3_w of the PERF_SAMPLE_WEIGHT_STRUCT. The Retire Latency reports the number of elapsed core clocks between the retirement of the instruction indicated by the Instruction Pointer field of the PEBS record and the retirement of the prior instruction. That's quite useful to display the information with perf script. Add a new field retire_lat for the Retire Latency information.

The Retire Latency field is added in the var3_w of the PERF_SAMPLE_WEIGHT_STRUCT. The Retire Latency reports pipeline stall of this instruction compared to the previous instruction in cycles. That's quite useful to display the information with perf mem report. The p_stage_cyc for Power is also from the var3_w. Union the p_stage_cyc and retire_lat to share the code.

It'd be useful to filter other than the current aggregation mode. For example, users may want to see callstacks for specific locks only. Or they may want tasks from a certain callstack. The tracepoints already collected the information but it needs to check the condition again when processing the event. And it needs to change BPF to allow the key combinations. The lock contentions on 'rcu_state' spinlock can be monitored: $ sudo perf lock con -abv -L rcu_state sleep 1 ... contended total wait max wait avg wait type caller 4 151.39 us 62.57 us 37.85 us spinlock rcu_core+0xcb 0xffffffff81fd1666 _raw_spin_lock_irqsave+0x46 0xffffffff8172d76b rcu_core+0xcb 0xffffffff822000eb __softirqentry_text_start+0xeb 0xffffffff816a0ba9 __irq_exit_rcu+0xc9 0xffffffff81fc0112 sysvec_apic_timer_interrupt+0xa2 0xffffffff82000e46 asm_sysvec_apic_timer_interrupt+0x16 0xffffffff81d49f78 cpuidle_enter_state+0xd8 0xffffffff81d4a259 cpuidle_enter+0x29 1 30.21 us 30.21 us 30.21 us spinlock rcu_core+0xcb 0xffffffff81fd1666 _raw_spin_lock_irqsave+0x46 0xffffffff8172d76b rcu_core+0xcb 0xffffffff822000eb __softirqentry_text_start+0xeb 0xffffffff816a0ba9 __irq_exit_rcu+0xc9 0xffffffff81fc00c4 sysvec_apic_timer_interrupt+0x54 0xffffffff82000e46 asm_sysvec_apic_timer_interrupt+0x16 1 28.84 us 28.84 us 28.84 us spinlock rcu_accelerate_cbs_unlocked+0x40 0xffffffff81fd1c60 _raw_spin_lock+0x30 0xffffffff81728cf0 rcu_accelerate_cbs_unlocked+0x40 0xffffffff8172da82 rcu_core+0x3e2 0xffffffff822000eb __softirqentry_text_start+0xeb 0xffffffff816a0ba9 __irq_exit_rcu+0xc9 0xffffffff81fc0112 sysvec_apic_timer_interrupt+0xa2 0xffffffff82000e46 asm_sysvec_apic_timer_interrupt+0x16 0xffffffff81d49f78 cpuidle_enter_state+0xd8 ...

This is a preparation work to support complex keys of BPF maps. Now it has single value key according to the aggregation mode like stack_id or pid. But we want to use a combination of those keys. Then lock_contention_read() should still aggregate the result based on the key that was requested by user. The other key info will be used for filtering. So instead of creating a lock_stat entry always, Check if it's already there using lock_stat_find() first.

Add a target that generates a log file for running metric_test.py and make this a dependency on generating pmu-events.c. The log output is displayed if the test fails like (the test was modified to make it fail): ``` TEST /tmp/perf/pmu-events/metric_test.log F...... ====================================================================== FAIL: test_Brackets (__main__.TestMetricExpressions) ---------------------------------------------------------------------- Traceback (most recent call last): File "tools/perf/pmu-events/metric_test.py", line 33, in test_Brackets self.assertEqual((a * b + c).ToPerfJson(), 'a * b + d') AssertionError: 'a * b + c' != 'a * b + d' - a * b + c ? ^ + a * b + d ? ^ ---------------------------------------------------------------------- Ran 7 tests in 0.004s FAILED (failures=1) make[3]: *** [pmu-events/Build:32: /tmp/perf/pmu-events/metric_test.log] Error 1 ``` However, normal execution will just show the TEST line. This is roughly modeled on fortify testing in the kernel lib directory. Modify metric_test.py so that it is executable. This is necessary when PYTHON isn't specified in the build, the normal case. Use variables to make the paths to files clearer and more consistent. Committer notes: Add pmu-events/metric_test.log to tools/perf/.gitignore and to the 'clean' target on tools/perf/Makefile.perf.

Turn a perf json event into an event, metric or both. This reduces the number of events needed to scan to find an event or metric. As events no longer need the relatively seldom used metric fields, 4 bytes is saved per event. This reduces the big C string's size by 335kb (14.8%) on x86. Note, for the test PMU architecture pme_test_soc_cpu is renamed pmu_events__test_soc_cpu for consistency with the event vs metric naming convention.

Previous changes separated the uses of pmu_event and pmu_metric, however, both structures contained all the variables of event and metric. This change removes the event variables from metric and the metric variables from event. Note, this change removes the setting of evsel's metric_name/expr as these fields are no longer part of struct pmu_event. The metric remains but is no longer implicitly requested when the event is. This impacts a few Intel uncore events, however, as the ScaleUnit is shared by the event and the metric this utility is questionable. Also the MetricNames look broken (contain spaces) in some cases and when trying to use the functionality with '-e' the metrics fail but regular metrics with '-M' work. For example, on SkylakeX '-M' works: ``` $ perf stat -M LLC_MISSES.PCIE_WRITE -a sleep 1 Performance counter stats for 'system wide': 0 UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 # 57896.0 Bytes LLC_MISSES.PCIE_WRITE (49.84%) 7,174 UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 (49.85%) 0 UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 (50.16%) 63 UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 (50.15%) 1.004576381 seconds time elapsed ``` whilst the event '-e' version is broken even with --group/-g (fwiw, we should also remove -g [1]): ``` $ perf stat -g -e LLC_MISSES.PCIE_WRITE -g -a sleep 1 Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART2 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART1 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART3 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Add UNC_IIO_DATA_REQ_OF_CPU.MEM_WRITE.PART0 event to groups to get metric expression for LLC_MISSES.PCIE_WRITE Performance counter stats for 'system wide': 27,316 Bytes LLC_MISSES.PCIE_WRITE 1.004505469 seconds time elapsed ``` The code also carries warnings where the user is supposed to select events for metrics [2] but given the lack of use of such a feature, let's clean the code and just remove.
