[for-next][PATCH 2/2] tracing/osnoise: Fix resetting of tracepoints

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> If a timerlat tracer is started with the osnoise option OSNOISE_WORKLOAD disabled, but then that option is enabled and timerlat is removed, the tracepoints that were enabled on timerlat registration do not get disabled. If the option is disabled again and timelat is started, then it triggers a warning in the tracepoint code due to registering the tracepoint again without ever disabling it. Do not use the same user space defined options to know to disable the tracepoints when timerlat is removed. Instead, set a global flag when it is enabled and use that flag to know to disable the events. ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo timerlat > /sys/kernel/tracing/current_tracer ~# echo OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo nop > /sys/kernel/tracing/current_tracer ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo timerlat > /sys/kernel/tracing/current_tracer Triggers: ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1337 at kernel/tracepoint.c:294 tracepoint_add_func+0x3b6/0x3f0 Modules linked in: CPU: 6 UID: 0 PID: 1337 Comm: rtla Not tainted 6.13.0-rc4-test-00018-ga867c441128e-dirty #73 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:tracepoint_add_func+0x3b6/0x3f0 Code: 48 8b 53 28 48 8b 73 20 4c 89 04 24 e8 23 59 11 00 4c 8b 04 24 e9 36 fe ff ff 0f 0b b8 ea ff ff ff 45 84 e4 0f 84 68 fe ff ff <0f> 0b e9 61 fe ff ff 48 8b 7b 18 48 85 ff 0f 84 4f ff ff ff 49 8b RSP: 0018:ffffb9b003a87ca0 EFLAGS: 00010202 RAX: 00000000ffffffef RBX: ffffffff92f30860 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff9bf59e91ccd0 RDI: ffffffff913b6410 RBP: 000000000000000a R08: 00000000000005c7 R09: 0000000000000002 R10: ffffb9b003a87ce0 R11: 0000000000000002 R12: 0000000000000001 R13: ffffb9b003a87ce0 R14: ffffffffffffffef R15: 0000000000000008 FS: 00007fce81209240(0000) GS:ffff9bf6fdd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000055e99b728000 CR3: 00000001277c0002 CR4: 0000000000172ef0 Call Trace: <TASK> ? __warn.cold+0xb7/0x14d ? tracepoint_add_func+0x3b6/0x3f0 ? report_bug+0xea/0x170 ? handle_bug+0x58/0x90 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? __pfx_trace_sched_migrate_callback+0x10/0x10 ? tracepoint_add_func+0x3b6/0x3f0 ? __pfx_trace_sched_migrate_callback+0x10/0x10 ? __pfx_trace_sched_migrate_callback+0x10/0x10 tracepoint_probe_register+0x78/0xb0 ? __pfx_trace_sched_migrate_callback+0x10/0x10 osnoise_workload_start+0x2b5/0x370 timerlat_tracer_init+0x76/0x1b0 tracing_set_tracer+0x244/0x400 tracing_set_trace_write+0xa0/0xe0 vfs_write+0xfc/0x570 ? do_sys_openat2+0x9c/0xe0 ksys_write+0x72/0xf0 do_syscall_64+0x79/0x1c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e Cc: stable(a)vger.kernel.org Cc: Masami Hiramatsu <mhiramat(a)kernel.org> Cc: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com> Cc: Tomas Glozar <tglozar(a)redhat.com> Cc: Gabriele Monaco <gmonaco(a)redhat.com> Cc: Luis Goncalves <lgoncalv(a)redhat.com> Cc: John Kacur <jkacur(a)redhat.com> Link: https://lore.kernel.org/20250123204159.4450c88e@gandalf.local.home Fixes: e88ed227f639e ("tracing/timerlat: Add user-space interface") Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- kernel/trace/trace_osnoise.c | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) diff --git a/kernel/trace/trace_osnoise.c b/kernel/trace/trace_osnoise.c index b9f96c77527d..23cbc24ed292 100644 --- a/kernel/trace/trace_osnoise.c +++ b/kernel/trace/trace_osnoise.c @@ -1229,6 +1229,8 @@ static void trace_sched_migrate_callback(void *data, struct task_struct *p, int } } +static bool monitor_enabled; + static int register_migration_monitor(void) { int ret = 0; @@ -1237,16 +1239,25 @@ static int register_migration_monitor(void) * Timerlat thread migration check is only required when running timerlat in user-space. * Thus, enable callback only if timerlat is set with no workload. */ - if (timerlat_enabled() && !test_bit(OSN_WORKLOAD, &osnoise_options)) + if (timerlat_enabled() && !test_bit(OSN_WORKLOAD, &osnoise_options)) { + if (WARN_ON_ONCE(monitor_enabled)) + return 0; + ret = register_trace_sched_migrate_task(trace_sched_migrate_callback, NULL); + if (!ret) + monitor_enabled = true; + } return ret; } static void unregister_migration_monitor(void) { - if (timerlat_enabled() && !test_bit(OSN_WORKLOAD, &osnoise_options)) - unregister_trace_sched_migrate_task(trace_sched_migrate_callback, NULL); + if (!monitor_enabled) + return; + + unregister_trace_sched_migrate_task(trace_sched_migrate_callback, NULL); + monitor_enabled = false; } #else static int register_migration_monitor(void) -- 2.45.2

[for-next][PATCH 1/2] rv: Reset per-task monitors also for idle tasks

by Steven Rostedt

From: Gabriele Monaco <gmonaco(a)redhat.com> RV per-task monitors are implemented through a monitor structure available for each task_struct. This structure is reset every time the monitor is (re-)started, to avoid inconsistencies if the monitor was activated previously. To do so, we reset the monitor on all threads using the macro for_each_process_thread. However, this macro excludes the idle tasks on each CPU. Idle tasks could be considered tasks on their own right and it should be up to the model whether to ignore them or not. Reset monitors also on the idle tasks for each present CPU whenever we reset all per-task monitors.
