From 8132787168fa57da870edfb816589588d4620e1b Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sat, 8 Jul 2023 20:20:22 -0700 Subject: til: measure til_module_render() durations This stows the duration (in ticks (which are ms for now)) of a given module context's most recent, as well as tracking the max, in til_module_context_t. For now it's also added to --print-module-contexts output, but this is still rather primitive and nearly inscrutible in practice... that output is a flickery and unsorted mess during playback. But this is just a start. Ticks may need to move up to microseconds if it'll also be the units for measuring timings. Right now things are slow enough that the low-hanging fruit stand out as multiple if not dozens of milliseconds so it's still useful for now. --- src/til_module_context.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/til_module_context.h') diff --git a/src/til_module_context.h b/src/til_module_context.h index e4c0bca..cb607f2 100644 --- a/src/til_module_context.h +++ b/src/til_module_context.h @@ -17,6 +17,10 @@ struct til_module_context_t { */ unsigned refcount; + + /* for profiling */ + unsigned last_render_duration, max_render_duration; + unsigned renders_count; }; void * til_module_context_new(const til_module_t *module, size_t size, til_stream_t *stream, unsigned seed, unsigned ticks, unsigned n_cpus, til_setup_t *setup); -- cgit v1.2.1
