From ade362b53d721bc2e2c7a62a30c4345014e5f5ce Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sat, 23 Nov 2019 16:08:07 -0800 Subject: rototiller: pass num_cpus to .create_context() Back in the day, there was no {create,destroy}_context(), so passing num_cpus to just prepare_frame made sense. Modules then would implicitly initialize themselves on the first prepare_frame() call using a static initialized variable. Since then things have been decomposed a bit for more sophisticated (and cleaner) modules. It can be necessary to allocate per-cpu data structures and the natural place to do that is @ create_context(). So this commit wires that up. A later commit will probably have to plumb a "current cpu" identifier into the render_fragment() function. Because a per-cpu data structure isn't particularly useful if you can't easily address it from within your execution context. --- src/rototiller.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/rototiller.h') diff --git a/src/rototiller.h b/src/rototiller.h index ca2559a..e60eece 100644 --- a/src/rototiller.h +++ b/src/rototiller.h @@ -11,7 +11,7 @@ typedef struct settings_t settings; typedef struct setting_desc_t setting_desc_t; typedef struct rototiller_module_t { - void * (*create_context)(void); + void * (*create_context)(unsigned n_cpus); void (*destroy_context)(void *context); void (*prepare_frame)(void *context, unsigned n_cpus, fb_fragment_t *fragment, rototiller_fragmenter_t *res_fragmenter); void (*render_fragment)(void *context, fb_fragment_t *fragment); -- cgit v1.2.1
