From 0a8088b3b34f9efed3f8905969a1d16bfd485a65 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sat, 19 Aug 2023 12:07:52 -0700 Subject: til_stream: set frame in til_stream_pipe_set_driving_tap() This needs the stream pulled in so the signature changed to accomodate that. Also modules/rkt was calling this conditionally which won't be compatible with the per-frame driver race model, so always call it to maintain the driving position every frame. --- src/modules/rkt/rkt.c | 7 +++++-- src/til_stream.c | 4 +++- src/til_stream.h | 2 +- 3 files changed, 9 insertions(+), 4 deletions(-) (limited to 'src') diff --git a/src/modules/rkt/rkt.c b/src/modules/rkt/rkt.c index ab55d0f..82dff44 100644 --- a/src/modules/rkt/rkt.c +++ b/src/modules/rkt/rkt.c @@ -202,9 +202,12 @@ static int rkt_pipe_update(void *context, til_stream_pipe_t *pipe, const void *o return 0; } + /* TODO: it would be nice if we could just use the same til_stream_tap() API as everything + * else does. til_stream_pipe_set_driving_tap() shouldn't really be necessary, since rkt'd + * _always_ win the race to drive for pipes under rkt's purview. + */ rkt_pipe->tap.inactive = 0; - if (driving_tap != &rkt_pipe->tap) - til_stream_pipe_set_driving_tap(pipe, &rkt_pipe->tap); + til_stream_pipe_set_driving_tap(ctxt->til_module_context.stream, pipe, &rkt_pipe->tap); /* otherwise get the current interpolated value from the rocket track @ owner_foo->track * to update owner_foo->var.[fd], which _should_ be the driving tap. diff --git a/src/til_stream.c b/src/til_stream.c index eec0af4..3c0a4f5 100644 --- a/src/til_stream.c +++ b/src/til_stream.c @@ -516,11 +516,13 @@ void til_stream_pipe_set_owner(til_stream_pipe_t *pipe, const void *owner, const /* NULLing out the driving_tap isn't supported, since the tap name is part of the pipe's identity, * just set tap.inactive to indicate another tap should take over driving. */ -void til_stream_pipe_set_driving_tap(til_stream_pipe_t *pipe, const til_tap_t *driving_tap) +void til_stream_pipe_set_driving_tap(til_stream_t *stream, til_stream_pipe_t *pipe, const til_tap_t *driving_tap) { + assert(stream); assert(pipe); assert(driving_tap); + pipe->frame = stream->frame; pipe->driving_tap = driving_tap; } diff --git a/src/til_stream.h b/src/til_stream.h index 54bbdc5..317fe8f 100644 --- a/src/til_stream.h +++ b/src/til_stream.h @@ -66,7 +66,7 @@ void til_stream_fprint_pipes(til_stream_t *stream, FILE *out); int til_stream_for_each_pipe(til_stream_t *stream, til_stream_pipe_iter_func_t pipe_cb, void *cb_arg); void til_stream_pipe_set_owner(til_stream_pipe_t *pipe, const void *owner, const void *owner_foo); -void til_stream_pipe_set_driving_tap(til_stream_pipe_t *pipe, const til_tap_t *driving_tap); +void til_stream_pipe_set_driving_tap(til_stream_t *stream, til_stream_pipe_t *pipe, const til_tap_t *driving_tap); typedef int (til_stream_module_context_iter_func_t)(void *context, til_stream_module_context_t *module_context, size_t n_module_contexts, const til_module_context_t **contexts); -- cgit v1.2.1
