There are a number of regressions and hard to reproduce issues that find
their roots in this change, so revert it until those can be ironed out
some more.
This reverts commit 4bb1f976d5397949be06510524bede5ae3bbfe0a.

It's needed when the surface window is a depth 24 descendant of a depth
32 toplevel window.
xwl_source_validate ensures the toplevel window pixmap has valid
contents when a client reads from it, or when the window hierarchy /
geometry changes. It's never called in the normal fullscreen application
case, so there's no GPU copy overhead with that.
v2:
* Don't try to redirect a depth 32 descendant of different-depth
ancestors, the alpha channel wouldn't be handled correctly.

This protocol allows for explicit synchronization of GPU operations by
Wayland clients and the compositor. Xwayland can make use of this to
ensure any rendering it initiates has completed before the target image
is accessed by the compositor, without having to rely on kernel-level
implicit synchronization.
Furthermore, for X11 clients that also support explicit synchronization
using the mechanisms exposed in the DRI3 and Present extensions, this
Wayland protocol allows us to simply forward the timeline, acquire, and
release points directly to the compositor, ideally avoiding any
premature stalls in the presentation pipeline.

Together, DRI3 1.4 and Present 1.4 allow clients to explicitly
synchronize GPU rendering with presentation using DRM syncobjs. Here we
add the necessary support to Xwayland's glamor and Present
infrastructure to enable this functionality.

This allows e.g.

Assuming the same number of window buffers, this results in one less
pixmap per toplevel window, saving pixmap storage.
v2:
* Preserve xwl_window_buffer_get_available behaviour (Olivier Fourdan)
v3:
* Leave RegionEmpty call where it was in xwl_window_buffers_get_pixmap,
so it takes effect for a newly allocated struct xwl_window_buffer.
* Consolidate xwl_window_buffer->pixmap assignment in the same place.
|
|
Use xwl_window_buffers_dispose instead. The pixmaps will need to be
re-created anyway, so keeping around the xwl_window_buffers doesn't
buy much. And dropping this makes the next commit simpler.
Also fold xwl_window_buffer_destroy_pixmap into its only remaining
caller, xwl_window_buffer_maybe_dispose.
v2: (Olivier Fourdan)
* Fix up indentation in xwl_window_set_window_pixmap
* Leave xwl_window_buffer_destroy_pixmap helper

glamor ensures that a depth 32 pixmap backing a depth 24 window contains
fully opaque alpha channel values for the window's pixels, so we can
allow this without implicit redirection, saving pixmap storage and
intermediate copies.

This commit is meant as an optimization, but has been identified as the
cause of multiple regressions reported in issues xorg/xserver#1564 and
xorg/xserver#1565.
Reverting that commit alone fixes the aforementioned issues, the rest of
the commits from xorg/xserver!1131 seem harmless and do not need
reverting.
This reverts commit d6c5999e943e43e800f976a48e774fbef77f5ef2.

This will be needed with the next commit: If a child window completely
obscures a toplevel ancestor of different depth, the child window can
use page flipping only if the depth of the presented pixmap matches that
of the window's backing pixmap, or the former may contain pixel values
which are not suitable for the toplevel window's depth.
