Update the icelakex metrics and events using the new tooling from: https://github.com/intel/perfmon The metrics are unchanged but the formulas differ due to parentheses, use of exponents and removal of redundant operations like "* 1". The order of metrics varies as TMA metrics are first converted and then removed if perfmon versions are found. The events are updated to 1.17, in particular uncore, with fixes to uncore events and improved descriptions. The formatting changes increase consistency across the json files. Signed-off-by:

The events are unchanged but unused json values are removed and implicit umasks of 0 are dropped.

We test metrics with fake events with fake values. The fake values may yield division by zero and so we count both up and down to try to avoid this. Unfortunately this isn't sufficient for some metrics and so don't fail the test for them. Add the metric name to debug output. Signed-off-by:

Namhyung Kim authored
The sort_entry->cmp() will be called for eventy sample data to find a matching entry. When it has 'srcline' sort key, that means it needs to call addr2line or libbfd everytime. This is not optimal because many samples will have same address and it just can call addr2line once. So postpone the actual srcline check to the sort_entry->collpase() and compare addresses in ->cmp(). Also it needs to add ->init() callback to make sure it has srcline info. If a sample has a unique data, chances are the entry can be sorted out by other (previous) keys and callbacks in sort_srcline never called. Signed-off-by:

In __hists__insert_output_entry(), it calls fmt->sort() for dynamic entries with NULL to update column width for tracepoint fields. But it's a hacky abuse of the sort callback, better to have a proper callback for that. I'll add more use cases later. Signed-off-by:

The filename__has_section() is to check if the given section name is in the binary. It'd be used for checking debug info for srcline. Committer notes: Added missing __maybe_unused to the unused filename__has_section() arguments in tools/perf/util/symbol-minimal.c. Signed-off-by:

Parametrized events are not only a powerpc domain. They occur on other platforms too (e.g. aarch64). They should be ignored in this testcase, since proper setup of the parameters is out of scope of this script. Let's not filter them out by PMU name, but rather based on the fact that they expect a parameter.

The -Y/--type-filter option is to filter the result for specific lock types only. It can accept comma-separated values. Note that it would accept type names like one in the output. spinlock, mutex, rwsem:R and so on. For RW-variant lock types, it converts the name to the both variants. In other words, "rwsem" is same as "rwsem:R,rwsem:W". Also note that "mutex" has two different encoding - one for sleeping wait, another for optimistic spinning. Add "mutex-spin" entry for the lock_type_table so that we can add it for "mutex" under the table. $ sudo ./perf lock record -a -- ./perf bench sched messaging $ sudo ./perf lock con -E 5 -Y spinlock contended total wait max wait avg wait type caller 802 1.26 ms 11.73 us 1.58 us spinlock __wake_up_common_lock+0x62 13 787.16 us 105.44 us 60.55 us spinlock remove_wait_queue+0x14 12 612.96 us 78.70 us 51.08 us spinlock prepare_to_wait+0x27 114 340.68 us 12.61 us 2.99 us spinlock try_to_wake_up+0x1f5 83 226.38 us 9.15 us 2.73 us spinlock folio_lruvec_lock_irqsave+0x5e Committer notes: Make get_type_flag() return UINT_MAX for error instad of -1UL, as that function returns 'unsigned int' and we store the value on a 'unsigned int' 'flags' variable which makes clang unhappy: 35 98.23 fedora:37 : FAIL clang version 15.0.6 (Fedora 15.0.6-1.fc37) builtin-lock.c:2012:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ builtin-lock.c:2021:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ builtin-lock.c:2037:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ 3 errors generated.
