The v1 version is deprecated and bound to be removed in the future from
all compositors. This patch adds a v1/v2 designator to everything
related to the protocol and prefers the v2 protocol if both are
available.
Additionally, renames the event handler to follow the Wayland interface
name, for consistency with the rest of the codebase.
Godot checks if there's Vulkan or GLES3 support.
If no support is found, it shows an error message.
However the code for this error message is left out when building with
opengl3=no
Initially the WaylandThread cursor code was supposed to be as stateless
as possible but, as time went on, this wasn't possible.
This expectation made the resulting API quite convoluted, so this patch
aims to simplify it substantially bot in terms of API surface and, most
importantly, in terms of actual implementation complexity.
This patch also fixes custom cursors since I accidentally changed the
mmap flags to MAP_PRIVATE some time ago. This took me hours to notice.
While experimenting with the recent "extent to title" PR, I noticed that
it's not guaranteed for a "button released" event to be emitted when
the pointer leaves the main surface, leaving some buttons stuck.
Not doing this for tablets since the spec makes this behavior clear and
explicit, so we (hopefully) shouldn't have this issue there.
Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
- Debug-only Breadcrumb info for debugging GPU crashes and device lost
- Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks
Functionality marked as "debug-only" is only available in debug or dev
builds.
Misc fixes:
- Early break optimization in RenderingDevice::uniform_set_create
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
Before, multiple capability events would instantiate the same object
over and over as long as its bit was set. This caused issues with
hotplug and device suspension.
This reduces even further the amount of work we have to do when scaling
and potentially improves input accuracy as now the input code is free
from any form of rounding.
Before of this patch, as explained in the usual
commented-wall-of-text-longer-than-the-actual-patch-itself™, due to the
multithreaded nature of the Wayland thread, it was possible to commit a
surface while the renderer was doing stuff, which was _very_ wrong.
Initially the consequences of such a sin weren't obvious but, now that
explicit synchronization is becoming more and more common, we can't
commit a buffer randomly without basically guaranteeing a nasty, nasty
crash (and we should have avoided commits altogether in the first place
to ensure atomic surface updates).
We now only trigger a commit _in the main thread_ when low processor usage
mode is on _and_ if we know that we won't be rendering anything as, due to
its intermittent nature, it makes "legacy" (pre xdg_wm_base v6) frame
callback based suspension quite annoying.
This avoids any assumption from the driver, which would otherwise select
a specific platform and potentially mess up everything, resulting
usually in a display server failure.
