2025-02-24perf report: Fix sample number stats for branch entry modeThomas Falcon
Currently, stats->nr_samples is incremented per entry in the branch stack instead of per sample taken. As a result, statistics of samples taken during perf record in --branch-filter or --branch-any mode does not seem correct. Instead call hists__inc_nr_samples() for each sample taken instead of for each entry in the branch stack.

2025-02-24perf machine: Reuse module path bufferIan Rogers
Rather than copying the path and appending the directory entry in a fresh path buffer, append to the path at the end of where it is for the recursion level.

2025-02-20perf parse-events: Tidy name token matchingIan Rogers
Prior to commit 70c90e4a6b2f ("perf parse-events: Avoid scanning PMUs before parsing") names (generally event names) excluded hyphen (minus) symbols as the formation of legacy names with hyphens was handled in the yacc code. That commit allowed hyphens supposedly making name_minus unnecessary. However, changing name_minus to name has issues in the term config tokens as then name ends up having priority over numbers and name allows matching numbers since commit 5ceb57990bf4 ("perf parse: Allow tracepoint names to start with digits "). It is also permissable for a name to match with a colon (':') in it when its in a config term list. To address this rename name_minus to term_name, make the pattern match name's except for the colon, add number matching into the config term region with a higher priority than name matching. This addresses an inconsistency and allows greater matching for names inside of term lists, for example, they may start with a number. Rename name_tag to quoted_name and update comments and helper functions to avoid str detecting quoted strings which was already done by the lexer.

2025-02-19perf tools: Improve startup time by reducing unnecessary stat() callsKrzysztof Łopatowski
When testing perf trace on NixOS, I noticed significant startup delays: - `ls`: ~2ms - `strace ls`: ~10ms - `perf trace ls`: ~550ms Profiling showed that 51% of the time is spent reading files, 26% in loading BPF programs, and 11% in `newfstatat`. This patch optimizes module path exploration by avoiding `stat()` calls unless necessary. For filesystems that do not implement `d_type` (DT_UNKNOWN), it falls back to the old behavior. See `readdir(3)` for details. This reduces `perf trace ls` time to ~500ms. A more thorough startup optimization based on command parameters would be ideal, but that is a larger effort.

2025-02-18perf script: Fix hangup in offline flamegraph reportNamhyung Kim
A recent change in the flamegraph script fixed an issue with live mode but it created another for offline mode. It needs to pass "-" to -i option to read from stdin in the live mode. Actually there's a logic to pass the option in the perf script code, but the script was written with "-- $@" which prevented the option to go to the perf script. So the previous commit added the hard-coded "-i -" to the report command. But it's a problem for the offline mode which expects input from a file and now it's stuck on reading from stdin. Let's remove the "-i - --" part and let it pass the options properly to perf script.

The struct dump_regs contains 512 bytes of cache_regs, meaning the two values in perf_sample contribute 1088 bytes of its total 1384 bytes size. Initializing this much memory has a cost reported by Tavian Barnes <tavianator@tavianator.com> as about 2.5% when running `perf script --itrace=i0`: https://lore.kernel.org/lkml/d841b97b3ad2ca8bcab07e4293375fb7c32dfce7.1736618095.git.tavianator@tavianator.com/ Adrian Hunter <adrian.hunter@intel.com> replied that the zero initialization was necessary and couldn't simply be removed. This patch aims to strike a middle ground of still zeroing the perf_sample, but removing 79% of its size by make user_regs and intr_regs optional pointers to zalloc-ed memory. To support the allocation accessors are created for user_regs and intr_regs. To support correct cleanup perf_sample__init and perf_sample__exit functions are created and added throughout the code base.
