It's constructed as a native backend headless backend, but uses a custom
monitor manager (based on MetaMonitorManagerNative) that creates a fake
monitor. Rendering is unconditionally done with the surfaceless
renderer.
The test devices used now use virtual devices, meaning some changes to
the tests to e.g. not set names, and not dealing with input devices
directly.

This is where the viewports are updated, and so lets move connecting the
signal together with it. It also helps a future change to the test
backend where it creates a custom monitor manager.

Add meta_kms_impl_device_open_non_privileged_fd() that returns a

The manager keeps track of which connectors are leasable in general,
which connectors and resources are already part of a lease, and keeps
track of when leases get revoked.
When leasing out connectors, the required drm resources to drive the
connectors are included in the lease as well.

When a plane is leased, it is assigned to a CRTC which is leased. When
trying to find a primary plane for a modeset, skip the assigned planes
on leased CRTCs to avoid sharing the resources with the leased process.

This allows us to keep track when primary and cursor plane assignments
on a CRTC are unassigned. With this commit, all planes which are
assigned are actually in use and can't be assigned to anything else.
We'll make use of that fact when we search for a leasable primary plane.

The lease_objects function takes connectors, CRTCs and planes which are
turned into a drm lease. The resulting lease can be revoked with
revoke_lease. With list_lessees the currently active leases can be
queried.

Add an environment variable (MUTTER_DEBUG_LEASE_CONNECTORS) that allows
set a ":" separated list of connector names as available for lease.
The names of the connectors can be found in "/sys/class/drm".
To illustrate it with an example, the names of the connectors and its
status can be fetched with this command:
$ for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
DP-1: disconnected
DP-2: disconnected
DP-3: disconnected
DP-4: disconnected
DP-5: connected
DP-6: connected
DP-7: disconnected
eDP-1: connected
HDMI-A-1: disconnected
And, to set "DP-5" and "DP-6" available for lease, the environment
variable can be set like:
MUTTER_DEBUG_LEASE_CONNECTORS=DP-5:DP-6

Let the ClutterFrame (or rather MetaFrameNative) own both the scanout
object and the framebuffer object, and let the frame itself live for as
long as it's needed. This allows to place fields that is related to a
single frame together, aiming to help reasoning about the lifetime of
the fields that were previously directly stored in MetaOnscreenNative.
Also take the opportunity to rename "current" to "presenting", to make
it clearer that frame's buffer is what is currently presenting to the
user.

If view initialization fails then don't add the view, rather than
adding a dummy offscreen view. This avoids flooding the log with
offscreen frame clock confusion:

Don't try to find the card, and then the render node from it, just ask
udev to list the render nodes directly. This avoids running into
permission errors when the user cannot open /dev/dri/card* even without

In case of empty regions (e.g. when locking the pointer) the pointer
was only forced to stay within the boundaries of its current pixel
(i.e. culling subpixel position), instead of the position where the
pointer lock did start.
Fixes: 07d24fe50 ("backends/native: Allow infinitely small pointer constraint regions")
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3749>
Since 07d24fe50 regions are not translated to their on-screen
coordinates anymore, but are relative to the origin stored in the
constraint. This origin however was not considered when checking whether
the pointer was within the constraint region. This meant that the
constraint region would appear to always be placed at 0,0 instead of on
the surface.
Fix this by using the cursor position relative to the origin.

Because `meta_kms_impl_device_simple_initable_init` is called in the
middle of `meta_kms_device_new`, the crtcs list for `MetaKmsDevice`
has not been populated yet. And thus the loop to detect missing
cursor planes and create fake ones never iterated. But the crtcs list
does already exist in `MetaKmsImplDevice` so iterate over that instead.

In the rare event that hotplugs destroy and then create a new EGLContext
with the exactly the same ID, this ensures we will forget the old program
which presumably wouldn't work in the new context. It will be recreated.

The EGL context can only import and blit an EGLImage if the
backing DMA buffer has a format modifier combination that is advertised
as supported and not marked as "external_only".
When the context can't blit the imported image, we can still paint using
it GL_OES_EGL_image_external using the texture target
GL_TEXTURE_EXTERNAL_OES.
However, treat drivers who doesn't support modifiers at all as if they
do support blitting, if the modifier is 'linear', to avoid regressions.

This is a critical part of any OpenGL program. Mesa allowed us to get
away without it and provided a sane default of the full buffer, but
Nvidia seems to default to an empty/zero viewport so would refuse to
paint any pixels.
In the OpenGL ES 2.0 spec this is ambiguous:
> In the initial state, w and h are set to the width and height,
> respectively, of the window into which the GL is to do its rendering.
because the first "window" used is EGL_NO_SURFACE in
init_secondary_gpu_data_gpu. It has no width or height.
In the OpenGL ES 3.0 spec the ambiguity is somewhat resolved:
> If the default framebuffer is bound but no default framebuffer is
> associated with the GL context (see chapter 4), then w and h are
> initially set to zero.
but not entirely resolved because neither spec says whether
EGL_NO_SURFACE should be treated as zero dimensions (Nvidia) or ignored
and not counted as the first "window" (Mesa).

As mentioned in the OES_EGL_image_external spec, there is no implicit
sync between the EGLImage producer and consumer. And in this code path
we don't have meta_drm_buffer_gbm_new_lock_front on the primary GPU to
do it for us either. So synchronization has to be done manually or else
the secondary GPU is likely to get an unfinished image.
This problem has only been observed when the secondary GPU is using the
Nvidia proprietary driver.
