From 982387011ff5cf654a49c835a86bf0e52675733b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Fri, 3 Aug 2012 16:29:12 -0400 Subject: [PATCH] compositor: Add weston_surface_schedule_repaint() for limited repaint In cases where we know the surface bounding box doesn't change in the next frame, we can limit redraws to only the outputs the surface is currently on. We could do even better by forcing the transform update so we know where the surface will be in the next frame, but this is a much simpler first step. --- src/compositor.c | 21 +++++++++++++++------ src/compositor.h | 3 +++ 2 files changed, 18 insertions(+), 6 deletions(-) diff --git a/src/compositor.c b/src/compositor.c index 5be5789..faed8f2 100644 --- a/src/compositor.c +++ b/src/compositor.c @@ -529,13 +529,23 @@ weston_surface_from_global(struct weston_surface *surface, } WL_EXPORT void +weston_surface_schedule_repaint(struct weston_surface *surface) +{ + struct weston_output *output; + + wl_list_for_each(output, &surface->compositor->output_list, link) + if (surface->output_mask & (1 << output->id)) + weston_output_schedule_repaint(output); +} + +WL_EXPORT void weston_surface_damage(struct weston_surface *surface) { pixman_region32_union_rect(&surface->damage, &surface->damage, 0, 0, surface->geometry.width, surface->geometry.height); - weston_compositor_schedule_repaint(surface->compositor); + weston_surface_schedule_repaint(surface); } WL_EXPORT void @@ -662,7 +672,7 @@ weston_surface_unmap(struct weston_surface *surface) wl_fixed_from_int(0)); } - weston_compositor_schedule_repaint(surface->compositor); + weston_surface_schedule_repaint(surface); } struct weston_frame_callback { @@ -1419,8 +1429,7 @@ surface_damage(struct wl_client *client, pixman_region32_union_rect(&es->damage, &es->damage, x, y, width, height); - - weston_compositor_schedule_repaint(es->compositor); + weston_surface_schedule_repaint(es); } static void @@ -1500,7 +1509,7 @@ surface_set_input_region(struct wl_client *client, surface->geometry.height); } - weston_compositor_schedule_repaint(surface->compositor); + weston_surface_schedule_repaint(surface); } static const struct wl_surface_interface surface_interface = { @@ -1758,7 +1767,7 @@ notify_motion(struct wl_seat *seat, uint32_t time, wl_fixed_t x, wl_fixed_t y) weston_surface_set_position(ws->sprite, ix - ws->hotspot_x, iy - ws->hotspot_y); - weston_compositor_schedule_repaint(ec); + weston_surface_schedule_repaint(ws->sprite); } } diff --git a/src/compositor.h b/src/compositor.h index ea6d82f..979ce66 100644 --- a/src/compositor.h +++ b/src/compositor.h @@ -642,6 +642,9 @@ void weston_surface_assign_output(struct weston_surface *surface); void +weston_surface_schedule_repaint(struct weston_surface *surface); + +void weston_surface_damage(struct weston_surface *surface); void -- 2.7.4
