2020-11-03perf vendor events: Fix DRAM_BW_Use 0 issue for CLX/SKXJin Yao2-2/+2
Ian reports an issue that the metric DRAM_BW_Use often remains 0. The metric expression for DRAM_BW_Use on CLX/SKX: "( 64 * ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) / 1000000000 ) / duration_time" The counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/ are scaled up by 64, that is to turn a count of cache lines into bytes, the count is then divided by 1000000000 to give GB. However, the counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/ have been scaled yet. The scale values are from sysfs, such as /sys/devices/uncore_imc_0/events/cas_count_read.scale. It's 6.103515625e-5 (64 / 1024.0 / 1024.0). So if we use original metric expression, the result is not correct. But the difficulty is, for SKL client, the counts are not scaled. The metric expression for DRAM_BW_Use on SKL: "64 * ( arb@event\\=0x81\\,umask\\=0x1@ + arb@event\\=0x84\\,umask\\=0x1@ ) / 1000000 / duration_time / 1000" root@kbl-ppc:~# perf stat -M DRAM_BW_Use -a -- sleep 1 Performance counter stats for 'system wide': 190 arb/event=0x84,umask=0x1/ # 1.86 DRAM_BW_Use 29,093,178 arb/event=0x81,umask=0x1/ 1,000,703,287 ns duration_time 1.000703287 seconds time elapsed The result is expected. So the easy way is just change the metric expression for CLX/SKX. This patch changes the metric expression to: "( ( ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) * 1048576 ) / 1000000000 ) / duration_time" 1048576 = 1024 * 1024.

2020-10-14perf jevents: Fix event code for events referencing std arch eventsJohn Garry1-8/+3
The event code for events referencing std arch events is incorrectly evaluated in json_events(). The issue is that je.event is evaluated properly from try_fixup(), but later NULLified from the real_event() call, as "event" may be NULL. Fix by setting "event" same je.event in try_fixup(). Also remove support for overwriting event code for events using std arch events, as it is not used.

2020-03-24perf jevents: Support test events folderJohn Garry1-0/+30
With the goal of supporting pmu-events test case, introduce support for a test events folder. These test events can be used for testing generation of pmu-event tables and alias creation for any arch. When running the pmu-events test case, these test events will be used as the platform-agnostic events, so aliases can be created per-PMU and validated against known expected values. To support the test events, add a "testcpu" entry in pmu_events_map[]. The pmu-events test will be able to lookup the events map for "testcpu", to verify the generated tables against expected values. The resultant generated pmu-events.c will now look like the following: struct pmu_event pme_ampere_emag[] = { { .name = "ldrex_spec", .event = "event=0x6c", .desc = "Exclusive operation spe...", .topic = "intrinsic", .long_desc = "Exclusive operation ...", }, ... }; struct pmu_event pme_test_cpu[] = { { .name = "uncore_hisi_ddrc.flux_wcmd", .event = "event=0x2", .desc = "DDRC write commands.

This patch updates the PMCs for AMD Zen1 core based processors (Family 17h; Models 0 through 2F) to be in accordance with PMCs as documented in the latest versions of the AMD Processor Programming Reference [1], [2] and [3]. Note that some events, such as FPU pipe assignment are missing in [1], and therefore [3] is included for full coverage of events. PMCs added: fpu_pipe_assignment.dual{0|1|2|3} fpu_pipe_assignment.total{0|1|2|3} ls_mab_alloc.dc_prefetcher ls_mab_alloc.stores ls_mab_alloc.loads bp_dyn_ind_pred bp_de_redirect PMC removed: ex_ret_cond_misp Cumulative counts, fpu_pipe_assignment.total and fpu_pipe_assignment.dual, existed in v1, but did expose port-level counters. ex_ret_cond_misp has been removed as it has been removed from the latest versions of the PPR, and when tested, always seems to sample zero as tested on a Ryzen 3400G system.

2020-03-24perf vendor events amd: Add Zen2 eventsVijay Thakkar7-0/+1117
This patch adds PMU events for AMD Zen2 core based processors, namely, Matisse (model 71h), Castle Peak (model 31h) and Rome (model 2xh), as documented in the AMD Processor Programming Reference for Matisse [1]. The model number regex has been set to detect all the models under family 17 that do not match those of Zen1, as the range is larger for zen2. Zen2 adds some additional counters that are not present in Zen1 and events for them have been added in this patch. Some counters have also been removed for Zen2 thatwere previously present in Zen1 and have been confirmed to always sample zero on zen2. These added/removed counters have been omitted for brevity but can be found here: https://gist.github.com/thakkarV/5b12ca5fd7488eb2c42e451e40bdd5f3 Note that PPR for Zen2 [1] does not include some counters that were documented in the PPR for Zen1 based processors [2]. After having tested these counters, some of them that still work for zen2 systems have been preserved in the events for zen2. The counters that are omitted in [1] but are still measurable and non-zero on zen2 (tested on a Ryzen 3900X system) are the following: PMC 0x000 fpu_pipe_assignment.{total|total0|total1|total2|total3}

2020-03-24perf vendor events amd: Restrict model detection for zen1 based processorsVijay Thakkar7-1/+1
This patch changes the previous blanket detection of AMD Family 17h processors to be more specific to Zen1 core based products only by replacing model detection regex pattern [[:xdigit:]]+ with ([12][0-9A-F]|[0-9A-F]), restricting to models 0 though 2f only. This change is required to allow for the addition of separate PMU events for Zen2 core based models in the following patches as those belong to family 17h but have different PMCs. Current PMU events directory has also been renamed to "amdzen1" from "amdfam17h" to reflect this specificity. Note that although this change does not break PMU counters for existing zen1 based systems, it does disable the current set of counters for zen2 based systems. Counters for zen2 have been added in the following patches in this patchset.

2019-10-19perf list: Hide deprecated events by defaultJin Yao3-7/+23
There are some deprecated events listed by perf list. But we can't remove them from perf list with ease because some old scripts may use them. Deprecated events are old names of renamed events. When an event gets renamed the old name is kept around for some time and marked with Deprecated. The newer Intel event lists in the tree already have these headers. So we need to keep them in the event list, but provide a new option to show them. The new option is "--deprecated". With this patch, the deprecated events are hidden by default but they can be displayed when option "--deprecated" is enabled.
