perf ui scripts: Switch FILENAME_MAX to NAME_MAX

2025-07-23T01:17:53+00:00

FILENAME_MAX is the same as PATH_MAX (4kb) in glibc rather than NAME_MAX's 255. Switch to using NAME_MAX and ensure the '\0' is accounted for in the path's buffer size. Signed-off-by: Ian Rogers Link: https://lore.kernel.org/r/20250717150855.1032526-3-irogers@google.com Signed-off-by: Namhyung Kim

perf script: Move find_scripts to browser/scripts.c

2024-12-18T19:24:32+00:00

The only use of find_scripts is in browser/scripts.c but the definition in builtin causes linking problems requiring a stub in python.c. Move the function to allow the stub to be removed.

perf: script: prefer capstone to XED

2024-02-21T02:07:34+00:00

Now perf can show assembly instructions with libcapstone for x86, and the capstone is better in general.

perf TUI: Don't ignore job control

2024-01-04T21:29:17+00:00

In its infinite wisdom, by default, SLang sets susp undef, and this can only be un-done by calling SLtty_set_suspend_state(true). After every SLang_init_tty(). Additionally, no provisions are made for maintaining the teletype attributes across suspend/continue (outside of curses emulation mode(?!), which provides full support, naturally), so we need to save and restore the flags ourselves, as well as reset the text colours when going under. We need to also re-draw the screen, and raising SIGWINCH, shockingly, Just Works. The correct solution would be to Not Use SLang, but as a stop-gap, this makes TUI 'perf report' usable.

tools ui popup: Allow returning hotkeys

2020-01-06T14:46:10+00:00

With this patch if an optional pointer is passed to ui__popup_menu() then when any key that is not being handled (ENTER, ESC, etc) is typed, it'll record that key in the pointer and return, allowing for hotkey processing on the caller. If NULL is passed, no change in logic, unhandled keys continue to be ignored.

perf tools: Remove util.h from where it is not needed

2019-09-20T12:19:20+00:00

Check that it is not needed and remove, fixing up some fallout for places where it was only serving to get something else. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-9h6dg6lsqe2usyqjh5rrues4@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf debug: No need to include ui/util.h

2019-09-20T12:19:20+00:00

Nothing from that file is used in util/debug.h, it is only needed in some places that get it indirectly via including util/debug.h, remove that entanglement.

perf auxtrace: Uninline functions that touch perf_session

2019-09-01T01:24:10+00:00

So that we don't carry the session.h include directive in auxtrace.h, which in turn opens a can of worms of files that were getting all sorts of things via that include, fix them all.

perf tools: Remove needless sort.h include directives

2019-09-01T01:24:10+00:00

Now that sort.h isn't included by any other header, we can check where it is really needed, i.e. we can remove it and be sure that it isn't being obtained indirectly.

perf debug: Remove needless include directives from debug.h

2019-08-31T22:10:19+00:00

All we need there is a forward declaration for 'union perf_event', so remove it from there and add missing header directives in places using things from this indirect include.
