Backends may move surfaces to different planes, in which case damage is
generated in the primary plane. This damage is usually passed to the
renderer, but in some cases the backend may decide to not render
anything (that's the case when drm compositor scans out a client
buffer). In that case the damage on the primary plane would be
discarded, leading to artifacts later.
This patch makes the backend's responsibility to clear the damage on
the primary plane, so that unrendered damage is kept for as long as
necessary.
This moves the EGLConfig, EGLContext and EGLDisplay fields into
gles2-renderer. It also moves EGLDisplay creation and EGLConfig
selection into gles2-renderer.
This introduces callbacks for output creation and destruction for the
gles2-renderer. This enables the gles2-renderer to have per-output
state. EGL surface creation is now done by the output_create callback
and the EGL surface is stored in the new per-output gles2-renderer
state. On the first output_create call, the gles2-renderer will setup
it's GL context. This is because EGL requires a EGL surface to be able
to use the GL context.
This makes drm_fb_get_from_bo() use drmModeAddFB2() if possible so that
drm_output_prepare_overlay_surface() can use this instead of keeping
track of the fbs and buffers itself.
Let the compositor generic code decide what to do when the buffer goes
away. We still have a valid reference do the bo, so we can still show
the client contents until something else triggers a repaint.
If the sprite is disabled and we're not enabling it on the next frame,
nothing is done in the vblank handler, so there's no need to ask for a
vblank event.
Add the concept of debug key bindings, that are bindings that activate
debug features in the compositor. The bindings are added to a list in
the compositor, but the triggering them is left to the shell.
On the shell side, a global debug key binding is added. When the user
presses mod-shift-space, the shell will invoke the debug bindings based
on the next key press.
This also converts the debug shortcuts for repaint debugging, fan
repaint debugging and the hide overlays shortcut in compositor-drm to
use the new infrastructure.
Pressing ctrl-alt-o will cause the overlays to be hidden, but surfaces
will still be assigned to different planes. This helps with debugging
of repaint culling below surfaces in other planes.
Culling of the repaint of a surface behind an opaque surface on the
same plane was broken by commit 547149a9 [1]. The idea of that commit
is that the damage obscured by an overlay would remain on the primary
plane damage and be repainted when the overlay moved. However, in the
case the two surfaces are on the same plane, the opaque one is not
obscured, so it ends up being repainted.
This commit adds an opaque field to struct weston_plane, that is built
incrementally when accumulating damage. The opaque region of surfaces
on the same plane are removed from the plane's damage, restoring the
previous culling behavior. But since damage behind opaque region of
other planes is maintained, the bug solved in the mentioned commit is
not regressed.

If we can find a boot_vga PCI GPU, we should prefer it over any other GPU
that is connected to the system. The boot_vga flag tells us that this GPU
is the primary system GPU.
This fixes problems on two-GPU-systems were the wrong GPU is used. It also
fixes systems were DisplayLink GPUs are available with lower IDs than PCI
GPUs (although, this seems unlikely).
Note that udev_enumerate guarantees that the entry-list is sorted. So for
systems that have platform-GPUs, these should almost always be reported
prior to hotpluggable (PCI, USB, ...) GPUs, as the kernel probes them
first.

If gbm_bo_import does not return a valid buffer for usage of
GBM_BO_USE_SCANOUT don't try and scan out the surface directly.
We've caught the SHM case explicitly earlier - this is to prevent other cases
where the bo cannot be scanned out.

We move the EGL and GLES2 output repaint code into a new gles2-render.c
file. The eglMakeCurrent, glViewPort, surface loop etc was duplicated
across all backends, but this patch moves it to a new file.
Draw the borders of all the triangles.
v1: original
v2: add keybinding to enable/disable fan debug (super-alt-space),
cycle colors to make it easier to see individual draws, and
redraw undamaged region to clean up previous frames debug
lines

This patch allows rotation and mirroring outputs for x11 and drm backends.
A new 'transform' key can be set in the [output] section. From the protocol:
"The flipped values correspond to an initial flip around a vertical axis
followed by rotation."
The transform key can be one of the following 8 strings:
normal
90
180
270
flipped
flipped-90
flipped-180
flipped-270
Not all hw supports hw cursors. Similar to the case with sprites, if
the driver does not support it, don't keep trying and spamming the log
with error messages.

They can't be imported by gbm, so no point in trying, and segfaulting
in gbm when we try to import (because it tries to deref the buffer as
a wl_drm_buffer).

A call to strcmp() is already made in output_section_done() and
output->config is set appropriately if mode is "off". There is
no need to duplicate that in create_output_for_connector().
As said by krh: "Maybe we should also just call it an evdev_device
instead, shorter [and] not really ambiguous."
[krh: if my typo filled irc is going in a commit message, I'm at least going
to insert the missing words.]

When the entire output is transformed or we're capturing the output
for screenshot or video, disable all output specific overlays
(drm planes, hw cursors etc) and move all surfaces into the primary
plane.
Weston's notify_keyboard_focus_*() assume that a keyboard is present, if
they are called. With evdev, there might not always be a keyboard.
Also clean up the variable definition in evdev_notify_keyborad_focus().
I read that function through many times and finally had to grep where
does 'all_keys' come from.

If the sysname of the udev device did not start with "event", the
function returned without unreferencing udev_device.
The function is refactored to have a common exit path that unrefs
udev_device. The return value semantics are not changed.

Move all udev-related and now drm backend specific code into
compositor-drm.c.
This makes evdev.c free of udev and launcher-util, and allows it to be
used on Android.
