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/modules/roto/roto.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/modules/roto') diff --git a/src/modules/roto/roto.c b/src/modules/roto/roto.c index c5c951d..050b129 100644 --- a/src/modules/roto/roto.c +++ b/src/modules/roto/roto.c @@ -32,7 +32,7 @@ static int32_t costab[FIXED_TRIG_LUT_SIZE], sintab[FIXED_TRIG_LUT_SIZE]; static uint8_t texture[256][256]; static color_t palette[2]; -static void * roto_create_context(void) +static void * roto_create_context(unsigned num_cpus) { return calloc(1, sizeof(roto_context_t)); } -- cgit v1.2.3
