From 9e8947e4d51ddafb40887b8a8ebfb1873615f9b6 Mon Sep 17 00:00:00 2001 From: Rose Hudson Date: Fri, 2 Jun 2023 10:25:07 +0100 Subject: add render timer API Based on five calls: wlr_render_timer_create - creates a timer which can be reused across frames on the same renderer wlr_renderer_begin_buffer_pass - now takes a timer so that backends can record when the rendering starts and finishes wlr_render_timer_get_time - should be called as late as possible so that queries can make their way back from the GPU wlr_render_timer_destroy - self-explanatory The timer is exposed as an opaque `struct wlr_render_timer` so that backends can store whatever they want in there. --- include/wlr/render/interface.h | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'include/wlr/render/interface.h') diff --git a/include/wlr/render/interface.h b/include/wlr/render/interface.h index 709ae481..c352efe1 100644 --- a/include/wlr/render/interface.h +++ b/include/wlr/render/interface.h @@ -49,7 +49,8 @@ struct wlr_renderer_impl { struct wlr_texture *(*texture_from_buffer)(struct wlr_renderer *renderer, struct wlr_buffer *buffer); struct wlr_render_pass *(*begin_buffer_pass)(struct wlr_renderer *renderer, - struct wlr_buffer *buffer); + struct wlr_buffer *buffer, struct wlr_buffer_pass_options *options); + struct wlr_render_timer *(*render_timer_create)(struct wlr_renderer *renderer); }; void wlr_renderer_init(struct wlr_renderer *renderer, @@ -79,6 +80,15 @@ struct wlr_render_pass_impl { const struct wlr_render_rect_options *options); }; +struct wlr_render_timer { + const struct wlr_render_timer_impl *impl; +}; + +struct wlr_render_timer_impl { + int (*get_duration_ns)(struct wlr_render_timer *timer); + void (*destroy)(struct wlr_render_timer *timer); +}; + void wlr_render_texture_options_get_src_box(const struct wlr_render_texture_options *options, struct wlr_fbox *box); void wlr_render_texture_options_get_dst_box(const struct wlr_render_texture_options *options, -- cgit v1.2.3
