| * | libperf threadmap: Add perf_thread_map__idx() | Ian Rogers | 2025-05-21 | 1 | -0/+12 |
| | | | | | | | | | | | | | | | | | | | | | | | | | Allow computation of thread map index from a PID. Note, with a 'struct perf_cpu_map' the sorted nature allows for a binary search to compute the index which isn't currently possible with a 'struct perf_thread_map' as they aren't guaranteed sorted.

| * | libperf threadmap: Don't segv for index 0 for the NULL 'struct ↵ | Ian Rogers | 2025-05-21 | 1 | -0/+5 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | perf_thread_map' pointer perf_thread_map__nr() returns length 1 if the perf_thread_map is NULL, meaning index 0 is valid. When perf_thread_map__pid() of index 0 is read then return the expected "any" -1 value. Assert this is only done for index 0.

| * | libperf: Add API for allocating new thread map array | Tzvetomir Stoyanov (VMware) | 2022-02-23 | 1 | -7/+17 |
| | | | | | | | | | | | | | | | | | The existing API perf_thread_map__new_dummy() allocates new thread map for one thread. I couldn't find a way to reallocate the map with more threads, or to allocate a new map for more than one thread. Having multiple threads in a thread map is essential for some use cases. That's why a new API is proposed, which allocates a new thread map for given number of threads: perf_thread_map__new_array() Signed-off-by: Tzvetomir Stoyanov (VMware) <[email protected]> Acked-by: Jiri Olsa <[email protected]> Cc: Ian Rogers <[email protected]> Link: https://lore.kernel.org/linux-perf-users/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> | ||||
| * | libperf: Rename arguments of perf_thread_map APIs | Tzvetomir Stoyanov (VMware) | 2022-02-23 | 1 | -6/+6 |
| | | | | | | | | | | | | | | | | The "int thread" input arguments of some perf_thead_map APIs are index of the thread in the thread map. In order to avoid confusion and to make the APIs consistent with perf_cpu_map APIs, those arguments are renamed to "int idx".

| * | libperf: Move to tools/lib/perf | Jiri Olsa | 2020-01-06 | 1 | -0/+91 |
| Move libperf from its current location under tools/perf to a separate directory under tools/lib/. Also change various paths (mainly includes) to reflect the libperf move to a separate directory and add a new directory under MANIFEST.
