perf tools: Move 'struct perf_sample' to a separate header file to disentangle headers

2022-10-31T14:06:41+00:00

Some places were including event.h just to get 'struct perf_sample',
move it to a separate place so that we speed up a bit the build.

2022-08-13T18:02:08+00:00

Hide that the pmu_event structs are an array with a new wrapper struct.

perf pmu-events: Don't assume pmu_event is an array

2022-08-13T18:01:31+00:00

The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.

This makes it difficult to refactor pmu_event.

Add a loop function taking a callback function that's passed the struct
pmu_event.

This way the pmu_event is only needed for one element and not an entire
array.

Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

perf pmu-events: Avoid passing pmu_events_map

2022-08-13T18:00:32+00:00

Preparation for hiding pmu_events_map as an implementation detail. While
the map is passed, the table of events is all that is normally wanted.

While modifying the function's types, rename pmu_events_map__find to
pmu_events_table__find to match later encapsulation. Similarly rename
pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.

perf pmu: Make pmu_event tables const.

2021-10-20T13:32:33+00:00

Make lookup nature of data structures clearer through their type. Reduce
scope of architecture specific pmu_event tables by making them static.

perf pmu: Add const to pmu_events_map.

2021-10-20T13:31:47+00:00

The pmu_events_map is generated at compile time and used for lookup. For
testing purposes we need to swap the map being used.

Having the pmu_events_map be non-const is misleading as it may be an out
argument.

Make it const and update uses so they work on const too.

perf pmu: Add pmu_events_map__find() function to find the common PMU map for the system

2021-04-08T17:24:14+00:00

Add a function to find the common PMU map for the system.

For arm64, a special variant is added. This is because arm64 supports
heterogeneous CPU systems. As such, it cannot be guaranteed that the
cpumap is same for all CPUs. So in case of heterogeneous systems, don't
return a cpumap.
