Previously picking involved +several GL operations per mouse movement, but now the GPU/GL isn't +used at all. + +By avoiding OpenGL and the graphics driver we also reduce CPU usage. +Despite reimplementing the logic on the CPU, it still takes less CPU +time than going through GL did. + +This new approach also dramatically reduces the number of picking paint +cycles required for cursor movement since the pickability of the entire +screen is calculated and cached. The cache is only invalidated when the +screen contents change so for typical desktop usage where the screen is +mostly idle, cursor movement doesn't incur anywhere near as many paint +cycles as it used to. + +CPU usage on an Intel i7-7700, tested with two different GPUs/drivers: + + | | Intel | Nvidia | + | ------: | --------: | -----: | + | Moving the mouse: | + | Before | 10% | 10% | + | After | 6% | 6% | + | Moving a window: | + | Before | 23% | 81% | + | After | 19% | 40% | + +Closes: https://gitlab.gnome.org/GNOME/mutter/issues/154, + https://gitlab.gnome.org/GNOME/mutter/issues/691 + +Helps significantly with: https://gitlab.gnome.org/GNOME/mutter/issues/283, + https://gitlab.gnome.org/GNOME/mutter/issues/590, + https://gitlab.gnome.org/GNOME/mutter/issues/700 + +https://gitlab.gnome.org/GNOME/mutter/merge_requests/189 +--- + clutter/clutter/clutter-actor-private.h | 2 - + clutter/clutter/clutter-actor.c | 256 +++++++---- + clutter/clutter/clutter-actor.h | 4 + + clutter/clutter/clutter-debug.h | 3 +- + clutter/clutter/clutter-main.c | 120 ----- + clutter/clutter/clutter-private.h | 5 - + clutter/clutter/clutter-stage-private.h | 16 +- + clutter/clutter/clutter-stage-window.c | 18 - + clutter/clutter/clutter-stage-window.h | 8 - + clutter/clutter/clutter-stage.c | 435 +++++++++++-------- + clutter/clutter/cogl/clutter-stage-cogl.c | 50 --- + clutter/clutter/deprecated/clutter-texture.c | 93 +--- + clutter/tests/conform/actor-pick.c | 99 +---- + clutter/tests/conform/meson.build | 1 - + clutter/tests/conform/texture.c | 84 ---- + src/compositor/meta-surface-actor.c | 27 +- + 16 files changed, 436 insertions(+), 785 deletions(-) + delete mode 100644 clutter/tests/conform/texture.c + +diff --git a/clutter/clutter/clutter-actor-private.h b/clutter/clutter/clutter-actor-private.h +index c44f6342f..9bf1a3049 100644 +--- a/clutter/clutter/clutter-actor-private.h ++++ b/clutter/clutter/clutter-actor-private.h +@@ -297,8 +297,6 @@ const gchar * _clutter_actor_get_debug_name + void _clutter_actor_push_clone_paint (void); + void _clutter_actor_pop_clone_paint (void); + +-guint32 _clutter_actor_get_pick_id (ClutterActor *self); +- + void _clutter_actor_shader_pre_paint (ClutterActor *actor, + gboolean repeat); + void _clutter_actor_shader_post_paint (ClutterActor *actor); +diff --git a/clutter/clutter/clutter-actor.c b/clutter/clutter/clutter-actor.c +index a7fecb830..5feae6574 100644 +--- a/clutter/clutter/clutter-actor.c ++++ b/clutter/clutter/clutter-actor.c +@@ -729,8 +729,6 @@ struct _ClutterActorPrivate + + gchar *name; /* a non-unique name, used for debugging */ + +- gint32 pick_id; /* per-stage unique id, used for picking */ +- + /* a back-pointer to the Pango context that we can use + * to create pre-configured PangoLayout + */ +@@ -1282,6 +1280,129 @@ clutter_actor_verify_map_state (ClutterActor *self) + + #endif /* CLUTTER_ENABLE_DEBUG */ + ++static gboolean ++_clutter_actor_transform_local_box_to_stage (ClutterActor *self, ++ const ClutterActorBox *box, ++ ClutterPoint vertices[4]) ++{ ++ ClutterActor *stage = _clutter_actor_get_stage_internal (self); ++ CoglMatrix stage_transform, inv_stage_transform; ++ CoglMatrix modelview, transform_to_stage; ++ int v; ++ ++ g_return_val_if_fail (CLUTTER_IS_ACTOR (self), FALSE); ++ g_return_val_if_fail (box != NULL, FALSE); ++ ++ g_return_val_if_fail (stage != NULL, FALSE); ++ g_return_val_if_fail (box->x1 <= box->x2, FALSE); ++ g_return_val_if_fail (box->y1 <= box->y2, FALSE); ++ ++ /* Below is generally equivalent to: ++ * ++ * _clutter_actor_get_relative_transformation_matrix (self, ++ * stage, ++ * &transform_to_stage); ++ * ++ * but we do it the hard way here instead so as to accurately include any ++ * cogl transformations that an actor's paint function might have added in. ++ * Those additional transformations are only known to cogl matrices and not ++ * known to the clutter getter like above.

The fallbacks don't exist any more and +`clutter_stage_cogl_schedule_update` now always succeeds even in the +absence of a `presentation_time` (since !363). + +The drawbacks to keeping "threaded swap wait" are: + + * `u.presentation_time = get_monotonic_time_ns ();` is a guess and not + an accurate hardware presentation time. + * It required blocking the main loop on every frame in + `_cogl_winsys_wait_for_gpu` due to `glFinish`. Any OpenGL programmer + will tell you calling `glFinish` is a bad idea because it kills CPU-GPU + parallelism. In my case, it was blocking the main loop for 1-3ms on + every mutter frame. It's easy to imagine slower (or higher resolution) + Nvidia systems would lose an even larger chunk of their frame interval + blocked in that function. This significantly crippled frame rates on + Nvidia systems. + +The benefit to keeping "threaded swap wait" is: + + * Its guess of `presentation_time` is likely a better guess by a few + milliseconds than the guess that `clutter_stage_cogl_schedule_update` + will make in its place. + +So "threaded swap wait" provided better sub-frame phase accuracy, but at +the expense of frame rates. And as soon as it starts causing frame drops, +that one and only benefit is lost. There is no reason to keep it. + +And in case you are wondering, the documentation for "threaded swap wait" +is now wrong (since !363): + + > The advantage of enabling this is that it will allow your main loop + > to do other work while waiting for the system to be ready to draw + > the next frame, instead of blocking in glXSwapBuffers()." + +At the time (before !363) it was true that "threaded swap wait" avoided +swap interval throttling that would occur as a result of +`master_clock_next_frame_delay` blindly returning zero and over-queuing +frames. That code no longer exists. And ironically the implementation of +"threaded swap wait" necessitates the same kind of blocking (to a lesser +extent) that it was designed to avoid. We can eliminate all blocking +however by deleting "threaded swap wait", which is now safe since !363. + +https://gitlab.gnome.org/GNOME/mutter/merge_requests/602 +--- + cogl/cogl/cogl-private.h | 3 - + cogl/cogl/cogl-renderer-private.h | 1 - + cogl/cogl/cogl-renderer.c | 11 -- + cogl/cogl/cogl-xlib-renderer.h | 30 ---- + cogl/cogl/winsys/cogl-winsys-glx.c | 240 +-------------------------- + src/backends/x11/meta-backend-x11.c | 6 - + src/backends/x11/meta-renderer-x11.c | 8 - + 7 files changed, 2 insertions(+), 297 deletions(-) + +diff --git a/cogl/cogl/cogl-private.h b/cogl/cogl/cogl-private.h +index 9f918b851..db0f08df0 100644 +--- a/cogl/cogl/cogl-private.h ++++ b/cogl/cogl/cogl-private.h +@@ -76,9 +76,6 @@ typedef enum + COGL_PRIVATE_FEATURE_GL_PROGRAMMABLE, + COGL_PRIVATE_FEATURE_GL_EMBEDDED, + COGL_PRIVATE_FEATURE_GL_WEB, +- /* This is currently only implemented for GLX, but isn't actually +- * that winsys dependent */ +- COGL_PRIVATE_FEATURE_THREADED_SWAP_WAIT, + + COGL_N_PRIVATE_FEATURES + } CoglPrivateFeature; +diff --git a/cogl/cogl/cogl-renderer-private.h b/cogl/cogl/cogl-renderer-private.h +index a308801a7..cc8f94bf1 100644 +--- a/cogl/cogl/cogl-renderer-private.h ++++ b/cogl/cogl/cogl-renderer-private.h +@@ -71,7 +71,6 @@ struct _CoglRenderer + Display *foreign_xdpy; + gboolean xlib_enable_event_retrieval; + gboolean xlib_want_reset_on_video_memory_purge; +- gboolean xlib_enable_threaded_swap_wait; + #endif + + CoglDriver driver; +diff --git a/cogl/cogl/cogl-renderer.c b/cogl/cogl/cogl-renderer.c +index 854aa1fdd..bdc9762e8 100644 +--- a/cogl/cogl/cogl-renderer.c ++++ b/cogl/cogl/cogl-renderer.c +@@ -270,17 +270,6 @@ cogl_xlib_renderer_request_reset_on_video_memory_purge (CoglRenderer *renderer, + + renderer->xlib_want_reset_on_video_memory_purge = enable; + } +- +-void +-cogl_xlib_renderer_set_threaded_swap_wait_enabled (CoglRenderer *renderer, +- gboolean enable) +-{ +- _COGL_RETURN_IF_FAIL (cogl_is_renderer (renderer)); +- /* NB: Renderers are considered immutable once connected */ +- _COGL_RETURN_IF_FAIL (!renderer->connected); +- +- renderer->xlib_enable_threaded_swap_wait = enable; +-} + #endif /* COGL_HAS_XLIB_SUPPORT */ + + gboolean +diff --git a/cogl/cogl/cogl-xlib-renderer.h b/cogl/cogl/cogl-xlib-renderer.h +index 3a3c08d64..e8fe43a51 100644 +--- a/cogl/cogl/cogl-xlib-renderer.h ++++ b/cogl/cogl/cogl-xlib-renderer.h +@@ -167,36 +167,6 @@ void + cogl_xlib_renderer_set_event_retrieval_enabled (CoglRenderer *renderer, + gboolean enable); + +-/** +- * cogl_xlib_renderer_set_threaded_swap_wait_enabled: (skip) +- * @renderer: a #CoglRenderer +- * @enable: The new value +- * +- * Sets whether Cogl is allowed to use a separate threaded to wait for the +- * completion of glXSwapBuffers() and call the frame callback for the +- * corresponding #CoglOnscreen.
