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/browser.h | 87 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 87 insertions(+) create mode 100644 tools/perf/ui/browser.h (limited to 'tools/perf/ui/browser.h') diff --git a/tools/perf/ui/browser.h b/tools/perf/ui/browser.h new file mode 100644 index 000000000..9d4404f9b --- /dev/null +++ b/tools/perf/ui/browser.h @@ -0,0 +1,87 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _PERF_UI_BROWSER_H_ +#define _PERF_UI_BROWSER_H_ 1 + +#include +#include +#include + +#define HE_COLORSET_TOP 50 +#define HE_COLORSET_MEDIUM 51 +#define HE_COLORSET_NORMAL 52 +#define HE_COLORSET_SELECTED 53 +#define HE_COLORSET_JUMP_ARROWS 54 +#define HE_COLORSET_ADDR 55 +#define HE_COLORSET_ROOT 56 + +struct ui_browser { + u64 index, top_idx; + void *top, *entries; + u16 y, x, width, height, rows, columns, horiz_scroll; + u8 extra_title_lines; + int current_color; + void *priv; + char *title; + char *helpline; + const char *no_samples_msg; + void (*refresh_dimensions)(struct ui_browser *browser); + unsigned int (*refresh)(struct ui_browser *browser); + void (*write)(struct ui_browser *browser, void *entry, int row); + void (*seek)(struct ui_browser *browser, off_t offset, int whence); + bool (*filter)(struct ui_browser *browser, void *entry); + u32 nr_entries; + bool navkeypressed; + bool use_navkeypressed; +}; + +int ui_browser__set_color(struct ui_browser *browser, int color); +void ui_browser__set_percent_color(struct ui_browser *browser, + double percent, bool current); +bool ui_browser__is_current_entry(struct ui_browser *browser, unsigned row); +void ui_browser__refresh_dimensions(struct ui_browser *browser); +void ui_browser__reset_index(struct ui_browser *browser); + +void ui_browser__gotorc_title(struct ui_browser *browser, int y, int x); +void ui_browser__gotorc(struct ui_browser *browser, int y, int x); +void ui_browser__write_nstring(struct ui_browser *browser, const char *msg, + unsigned int width); +void ui_browser__vprintf(struct ui_browser *browser, const char *fmt, va_list args); +void ui_browser__printf(struct ui_browser *browser, const char *fmt, ...); +void ui_browser__write_graph(struct ui_browser *browser, int graph); +void __ui_browser__line_arrow(struct ui_browser *browser, unsigned int column, + u64 start, u64 end); +void ui_browser__mark_fused(struct ui_browser *browser, unsigned int column, + unsigned int row, int diff, bool arrow_down); +void __ui_browser__show_title(struct ui_browser *browser, const char *title); +void ui_browser__show_title(struct ui_browser *browser, const char *title); +int ui_browser__show(struct ui_browser *browser, const char *title, + const char *helpline, ...); +void ui_browser__hide(struct ui_browser *browser); +int ui_browser__refresh(struct ui_browser *browser); +int ui_browser__run(struct ui_browser *browser, int delay_secs); +void ui_browser__update_nr_entries(struct ui_browser *browser, u32 nr_entries); +void ui_browser__handle_resize(struct ui_browser *browser); +void __ui_browser__vline(struct ui_browser *browser, unsigned int column, + u16 start, u16 end); + +int ui_browser__warning(struct ui_browser *browser, int timeout, + const char *format, ...); +int ui_browser__warn_unhandled_hotkey(struct ui_browser *browser, int key, int timeout, const char *help); +int ui_browser__help_window(struct ui_browser *browser, const char *text); +bool ui_browser__dialog_yesno(struct ui_browser *browser, const char *text); +int ui_browser__input_window(const char *title, const char *text, char *input, + const char *exit_msg, int delay_sec); +struct perf_session; +int tui__header_window(struct perf_session *session); + +void ui_browser__argv_seek(struct ui_browser *browser, off_t offset, int whence); +unsigned int ui_browser__argv_refresh(struct ui_browser *browser); + +void ui_browser__rb_tree_seek(struct ui_browser *browser, off_t offset, int whence); +unsigned int ui_browser__rb_tree_refresh(struct ui_browser *browser); + +void ui_browser__list_head_seek(struct ui_browser *browser, off_t offset, int whence); +unsigned int ui_browser__list_head_refresh(struct ui_browser *browser); + +void ui_browser__init(void); +#endif /* _PERF_UI_BROWSER_H_ */ -- cgit v1.3.1
