perf pmu: Make pmu_uncore_alias_match() public

2020-03-24T13:35:59Z

The perf pmu-events test will want to use pmu_uncore_alias_match(), so make it public.

perf pmu: Add is_pmu_core()

2020-03-24T13:35:59Z

Add a function to decide whether a PMU is a core PMU.

perf pmu: Refactor pmu_add_cpu_aliases()

2020-03-24T13:35:59Z

Create pmu_add_cpu_aliases_map() from pmu_add_cpu_aliases(), so the caller can pass the map; the pmu-events test would use this since there would be no CPUID matching to a mapfile there.

perf pmu: When using default config, record which bits of config were changed by the user

2019-11-22T13:48:13Z

Default config for a PMU is defined before selected events are parsed. That allows the user-entered config to override the default config. However that does not allow for changing the default config based on other options. For example, if the user chooses AUX area sampling mode, in the case of Intel PT, the psb_period needs to be small for sampling, so there is a need to set the default psb_period to 0 (2 KiB) in that case. However that should not override a value set by the user. To allow for that, when using default config, record which bits of config were changed by the user.

perf auxtrace: Add support for AUX area sample recording

2019-11-22T13:48:13Z

Add support for parsing and validating AUX area sample options. At present, the only option is the sample size, but it is also necessary to ensure that events are in a group with an AUX area event as the leader. Committer note: Add missing 'static inline' in front of auxtrace_parse_sample_options() for when we don't HAVE_AUXTRACE_SUPPORT.

perf list: Hide deprecated events by default

2019-10-19T18:35:01Z

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.

perf pmu: Change convert_scale from static to global

2019-09-01T01:27:51Z

The function convert_scale() can be used to convert string to unit and scale. For example, s = "6000000000ns"; convert_scale(s, &unit, &scale); unit = "ns", scale = 6000000000. Currently this function is static. This patch renames the function to perf_pmu__convert_scale and changes the function to global. No functional change.

perf cpu_map: Rename struct cpu_map to struct perf_cpu_map

2019-07-29T21:34:42Z

perf pmu: Remove set_drv_config API

2019-02-06T13:00:39Z

CoreSight was the only client of the PMU's set_drv_config() API. Now that it is no longer needed by CoreSight remove it from the code base.
