From 9cc63f8bcd560c760d0b12e15bba8f81c86237cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 14 Aug 2026 15:43:51 -0700 Subject: Merge branches 'expcb.2026.07.24a', 'misc.2026.07.30a', 'rcu-tasks.2026.07.30a', 'srcu.2026.08.11a' and 'torture.2026.08.14a' into HEAD Changes: Make expedited grace periods expedite normal RCU callbacks Miscellaneous fixes: * Improve diagnostic output with character task states. * Mark accesses to inform KCSAN of concurrency design. * Move from kmalloc() to kmalloc_obj(). * Documentation updates. * Improve handling of RCU deferred quiescent states. * Clean up unused function arguments and structure fields. * Reduce show_rcu_gp_kthreads() stack space. Tasks RCU updates: * Clean up after SRCU re-implementation of Tasks Trace RCU. * Mark accesses to inform KCSAN of concurrency design. * Add ->lazy_timer status to diagnostic output. * Remove an unnecessary memory barrier. * Fix a data race, courtesy of KCSAN. * Documentation updates. * Convert cond_resched_tasks_rcu_qs() from macro to static inline function. SRCU updates: * Add Rust helpers for SRCU. * Avoid losing queued work at cleanup_srcu_struct() time. Torture-test updates: * Preparation work for immediate RCU priority deboosting. * Test RCU readers from real interrupt handlers (as opposed to softirq). * Simplify code through use of cpumask_next_wrap(). * Improve diagnostic output with character task states. * Add rcutorture.nwriters parameter to allow lightweight stall testing, and rcutorture.stall_only to make doing so easier. * Test an RCU Tasks Trace grace period implying an RCU grace period. * Make RCU Tasks Trace torturing track reader batches. * Fix a data race, courtesy of KCSAN. * Plug a shuffle_tmp_mask memory leak on kthread spawn failure. --- tools/perf/ui/util.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 tools/perf/ui/util.h (limited to 'tools/perf/ui/util.h') diff --git a/tools/perf/ui/util.h b/tools/perf/ui/util.h new file mode 100644 index 000000000..e30cea807 --- /dev/null +++ b/tools/perf/ui/util.h @@ -0,0 +1,24 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _PERF_UI_UTIL_H_ +#define _PERF_UI_UTIL_H_ 1 + +#include + +int ui__getch(int delay_secs); +int ui__popup_menu(int argc, char * const argv[], int *keyp); +int ui__help_window(const char *text); +int ui__dialog_yesno(const char *msg); +void __ui__info_window(const char *title, const char *text, const char *exit_msg); +void ui__info_window(const char *title, const char *text); +int ui__question_window(const char *title, const char *text, + const char *exit_msg, int delay_secs); + +struct perf_error_ops { + int (*error)(const char *format, va_list args); + int (*warning)(const char *format, va_list args); +}; + +int perf_error__register(struct perf_error_ops *eops); +int perf_error__unregister(struct perf_error_ops *eops); + +#endif /* _PERF_UI_UTIL_H_ */ -- cgit v1.3.1
