From 45d1f956b35fa9003106716e42425cc86cadc7a1 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sun, 1 May 2022 11:27:23 -0700 Subject: til: introduce some generic fragmenters for convenience Most of the threaded modules have settled down on two basic forms of fragmenter function: 1. a slice per cpu, where tile-oriented locality isn't useful 2. ~64x64 tiles, in scenarios where screen-space locality helps Now that n_cpus is wired up to the fragmenter, #1 can be fulfilled without requiring a module-private context plumbing n_cpus from create_context(). A future commit will replace some module-specific fragmenters by returning one of these instead as res_fragmenter in their prepare_frame(), wherever applicable. --- src/til.c | 14 ++++++++++++++ src/til.h | 2 ++ 2 files changed, 16 insertions(+) (limited to 'src') diff --git a/src/til.c b/src/til.c index 5d375c3..ce880b3 100644 --- a/src/til.c +++ b/src/til.c @@ -291,3 +291,17 @@ int til_module_randomize_setup(const til_module_t *module, til_setup_t **res_set return r; } + + +/* generic fragmenter using a horizontal slice per cpu according to n_cpus */ +int til_fragmenter_slice_per_cpu(void *context, unsigned n_cpus, const til_fb_fragment_t *fragment, unsigned number, til_fb_fragment_t *res_fragment) +{ + return til_fb_fragment_slice_single(fragment, n_cpus, number, res_fragment); +} + + +/* generic fragmenter using 64x64 tiles, ignores n_cpus */ +int til_fragmenter_tile64(void *context, unsigned n_cpus, const til_fb_fragment_t *fragment, unsigned number, til_fb_fragment_t *res_fragment) +{ + return til_fb_fragment_tile_single(fragment, 64, number, res_fragment); +} diff --git a/src/til.h b/src/til.h index 605dba1..c422914 100644 --- a/src/til.h +++ b/src/til.h @@ -38,5 +38,7 @@ int til_module_create_context(const til_module_t *module, unsigned ticks, til_se void * til_module_destroy_context(const til_module_t *module, void *context); int til_module_setup(til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, til_setup_t **res_setup); int til_module_randomize_setup(const til_module_t *module, til_setup_t **res_setup, char **res_arg); +int til_fragmenter_slice_per_cpu(void *context, unsigned n_cpus, const til_fb_fragment_t *fragment, unsigned number, til_fb_fragment_t *res_fragment); +int til_fragmenter_tile64(void *context, unsigned n_cpus, const til_fb_fragment_t *fragment, unsigned number, til_fb_fragment_t *res_fragment); #endif -- cgit v1.2.3
