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/builtin.h | 54 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 tools/perf/builtin.h (limited to 'tools/perf/builtin.h') diff --git a/tools/perf/builtin.h b/tools/perf/builtin.h new file mode 100644 index 000000000..40c4078c2 --- /dev/null +++ b/tools/perf/builtin.h @@ -0,0 +1,54 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef BUILTIN_H +#define BUILTIN_H + +struct feature_status { + const char *name; + const char *macro; + const char *tip; + int is_builtin; +}; + +extern struct feature_status supported_features[]; + +void feature_status__printf(const struct feature_status *feature); + +struct cmdnames; + +void list_common_cmds_help(void); +const char *help_unknown_cmd(const char *cmd, struct cmdnames *main_cmds); + +int cmd_annotate(int argc, const char **argv); +int cmd_bench(int argc, const char **argv); +int cmd_buildid_cache(int argc, const char **argv); +int cmd_buildid_list(int argc, const char **argv); +int cmd_check(int argc, const char **argv); +int cmd_config(int argc, const char **argv); +int cmd_c2c(int argc, const char **argv); +int cmd_diff(int argc, const char **argv); +int cmd_evlist(int argc, const char **argv); +int cmd_help(int argc, const char **argv); +int cmd_sched(int argc, const char **argv); +int cmd_kallsyms(int argc, const char **argv); +int cmd_list(int argc, const char **argv); +int cmd_record(int argc, const char **argv); +int cmd_report(int argc, const char **argv); +int cmd_stat(int argc, const char **argv); +int cmd_timechart(int argc, const char **argv); +int cmd_top(int argc, const char **argv); +int cmd_script(int argc, const char **argv); +int cmd_version(int argc, const char **argv); +int cmd_probe(int argc, const char **argv); +int cmd_kmem(int argc, const char **argv); +int cmd_lock(int argc, const char **argv); +int cmd_kvm(int argc, const char **argv); +int cmd_test(int argc, const char **argv); +int cmd_trace(int argc, const char **argv); +int cmd_inject(int argc, const char **argv); +int cmd_mem(int argc, const char **argv); +int cmd_data(int argc, const char **argv); +int cmd_ftrace(int argc, const char **argv); +int cmd_daemon(int argc, const char **argv); +int cmd_kwork(int argc, const char **argv); + +#endif -- cgit v1.3.1
