56d260cfb3 screen-cast-monitor-stream-src: Only send cursor bitmap when it changes
To avoid unnecessary pixel copying, only send the cursor bitmap when it

4e402b3972 screen-cast: Add 'cursor-mode' to allow decoupled cursor updates
The 'cursor-mode', which currently is limited to RecordMonitor(), allows
the user to either do screen casts where the cursor is hidden, embedded
in the framebuffer, or sent as PipeWire stream metadata.

The latter allows the user to get cursor updates sent, including the
cursor sprite, without requiring a stage paint each frame. Currently
this is done by using the cursor sprite texture, and either reading
directly from, or drawing to an offscreen framebuffer which is read from
instead, in case the texture is scaled.

22f865122c renderer/native: Prefer hardware rendering for primary GPU
Mutter prefers platform devices over anything else as the primary GPU.
This will not work too well, when a platform device does not actually
have a rendering GPU but is a display-only device. An example of this
are DisplayLink devices with the proprietary driver stack, which exposes
a DRM KMS platform device but without any rendering driver.

Mutter cannot rely on EGL init failing on such devices either, because
nowadays Mesa supports software renderers on GBM, so the initialization
may well succeed.

The hardware rendering capability is recognized by matching the GL
renderer string to the known Mesa software renderers. At this time,
there is no better alternative to detecting this.

The secondary GPU data is abused for the GL renderer, as the Cogl
context may not have been created yet.  Also, the Cogl context would
only be created on the primary GPU, but at this point the primary GPU
has not been chosen yet. Hence, GPU copy path GL context is used as a
proxy and predictor of what the Cogl context might be if it was created.
Mind, that even the GL flavour are not the same between Cogl and
secondary contexts, so this is stretch but it should be just enough.

The logic to choose the primary GPU is changed to always prefer hardware
rendering devices while also maintaining the old order of preferring
platform over boot_vga devices.

3d2ca9a67f renderer/native: Count devices on EGLDevice check
create_renderer_gpu_data_egl_device () relied on the primary GPU being
already chosen for the "EGLDevice currently only works with single GPU
systems" error message. A future patch will choose the primary GPU after
this, not before, so this check needs to be rewritten before the
initialization order is changed.

The new check is implemented exactly as the error message says: there
must be exactly one GPU, otherwise fail.

9182c8b801 backends/native: Move primary_gpu into MetaRendererNative
Make the choosing and identity of the primary GPU an internal detail to
the native renderer. MonitorManagerKms did not need it for anything.

The primary GPU logic remains unchanged.

This allows follow-up patches to change how the renderer chooses the
primary GPU. It will be easier for the renderer to use private
information for choosing.

1def099047 backends/native: Re-order primary GPU choosing logic
This is a step towards moving the primary GPU logic into the native
renderer exclusively. In the future the renderer will have one more
criterion on choosing the primary GPU than MetaMonitorManagerKms should
know about: does a GPU offer hardware rendering.

The choosing of primary GPU is separated from the discovery of GPUs.
When GPUs are discovered and added to the list, the MetaGpuKmsFlag is
now populated correctly and used in choosing.

Choosing the primary GPU is done after all GPUs have been found and is
slightly different from before:

- Skipping devices that do not belong to our seat now works instead of
becoming the primary GPU.

- Fall back to any non-platform, non-boot_vga device if neither kind is
found.

The old preference of platform over boot_vga device is kept.

The hotplug path will continue creating a gpu_kms without flags, because
at that point the primary GPU has already been chosen and the flags are
irrelevant.

177d0c2d63 gpu/kms: Use correct DRM event context version
DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
whatever version of libdrm is present. Mutter was blindly asserting it
supported whatever version that may be, even if it actually didn't.

With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.

Set the version as 2, which should be bumped only with the appropriate
version checks.

20c9ca25c0 screen-cast: Add screen-cast-window interface
Typically, to stream the content of a window, we need a way to copy the
content of its window-actor into a buffer, transform relative input
coordinates to relative position within the window-actor and a mean to
get the window bounds within the buffer.

For this purpose, add a new GType interface `MetaScreenCastWindow` with
the methods needed for screen-cast window mode:

 * meta_screen_cast_window_get_buffer_bounds()
 * meta_screen_cast_window_get_frame_bounds()
 * meta_screen_cast_window_transform_relative_position()
 * meta_screen_cast_window_capture_into()

This interface is meant to be implemented by `MetaWindowActor` which has
access to all the necessary bits to implement them.

08a5e660d3 backends: Add MetaInputMapper
This object takes care of mapping absolute devices to monitors,
to do so it uses 3 heuristics, in this order of preference:
- If a device is known to be builtin, it's assigned to the
  builtin monitor.
- If input device and monitor match sizes (with an error margin
  of 5%)
- If input device name and monitor vendor/product in EDID match
  somehow (from "full", through "partial", to just "vendor")

The most favorable outputs are then assigned to each device, making
sure not to assign two devices of the same kind to the same output.

This object replaces (and is mostly 1:1 with) GsdDeviceMapper in
g-s-d. That object would perform these same heuristics, and let
mutter indirectly know through settings changes. This object allows
doing the same in-process.

7d20101198 cogl-framebuffer: Remove swap_throttled config
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.

In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.

Removing it means less code, less branches when running,
and one less config option to deal with.

This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

262a3ecbd6 backends/x11: Flush connection after ungrab
Modal ungrabs may be followed by other clients trying to grab themselves,
flush the connection so we ensure the right order of events on the Xserver
side.

An example of this is js/ui/modalDialog.js in gnome-shell, as the alt-F2
dialog may launch X11 clients trying to grab themselves, commit a40daa3c22
in gnome-shell handled the case and added a gdk_display_sync() call to
ensure no grab existed at the time of executing.

This commit aims to achieve the same built in MetaBackend. A full sync
seems excessive though, as we just need to make sure the server got the
messages queued before the other side tries to grab, a XFlush seems
sufficient for this.

e9e4b2b72e renderer-native: Add hardware presentation timing
Add support for getting hardware presentation times from KMS (Wayland
sessions). Also implement cogl_get_clock_time which is required to compare
and judge the age of presentation timestamps.

For single monitor systems this is straightforward. For multi-monitor
systems though we have to choose a display to sync to. The compositor
already partially solves this for us in the case of only one display
updating because it will only use the subset of monitors that are
changing. In the case of multiple monitors consuming the same frame
concurrently however, we choose the fastest one (in use at the time).
Note however that we also need !73 to land in order to fully realize
multiple monitors running at full speed.

d4bea60e1a renderer/native: use cogl for CPU copy path
Use cogl_framebuffer_read_pixels_into_bitmap () instead of
glReadPixels () for the CPU copy path in multi-GPU support.

The cogl function employs several tricks to make the read-pixels as fast
as possible and does the y-flip as necessary. This should make the copy
more performant over all kinds of hardware.

This is expected to be used on virtual outputs (e.g. DisplayLink USB
docks and monitors) foremost, where the dumb buffer memory is just
regular system memory. If the dumb buffer memory is somehow slow, like
residing in discrete VRAM or having an unexpected caching mode, it may
be possible for the cogl function perform worse because it might do the
y-flip in-place in the dumb buffer. Hopefully that does not happen in
any practical scenario.

Calling meta_renderer_native_gles3_read_pixels () here was conceptually
wrong to begin with because it was done with the Cogl GL context of the
primary GPU, not on the GL ES 3 context of a secondary GPU. However,
due eglBindAPI being a no-op in Mesa and the glReadPixels () arguments
being compatible, it worked.

This patch adds a pixel format conversion table between DRM and Cogl
formats. It contains more formats than absolutely necessary and the
texture components field which is currently unused for completeness. See
Mutter issue #323. Making the table more complete documents better how
the pixel formats actually map so that posterity should be less likely
to be confused. This table could be shared with
shm_buffer_get_cogl_pixel_format () as well, but not with
meta_wayland_dma_buf_buffer_attach ().

On HP ProBook 4520s laptop (Mesa DRI Intel(R) Ironlake Mobile, Mesa
18.0.5), without this patch copy_shared_framebuffer_cpu () for a
DisplayLink output takes 5 seconds with a 1080p frame.  Obviously that
makes Mutter and gnome-shell completely unusable.  With this patch, that
function takes 13-18 ms which makes it usable if not fluent.

On Intel i7-4790 (Mesa DRI Intel(R) Haswell Desktop) machine, this patch
makes no significant difference (the copy takes 4-5 ms).

cbbd6d71bf renderer/native: use DRM formats for dumb buffers
Change the callers of init_dumb_fb () to use DRM format codes. DRM and
GBM format codes are identical, but since this is about dumb buffers,
DRM formats fit better.

The header /usr/include/gbm.h installed by Mesa says:

 * The FourCC format codes are taken from the drm_fourcc.h definition, and
 * re-namespaced. New GBM formats must not be added, unless they are
 * identical ports from drm_fourcc.

That refers to the GBM_FORMAT_* codes.

85e9784a22 renderer/native: fix next_fb_id race on CPU copy path
There was a race in setting next_fb_id when a secondary GPU was using
the CPU copy path. Losing this race caused the attempt to
drmModePageFlip () to FB ID 0 which is invalid and always fails. Failing
to flip causes Mutter to fall back to drmModeSetCrtc () permanently.

In meta_onscreen_native_swap_buffers_with_damage ():
- update_secondary_gpu_state_pre_swap_buffers ()
  - copy_shared_framebuffer_cpu () but only on the CPU copy path
    - secondary_gpu_state->gbm.next_fb_id is set
- wait_for_pending_flips ()
  - Waits for any remaining page flip events and executes and destroys
    the related page flip closures.
    - on_crtc_flipped ()
      - meta_onscreen_native_swap_drm_fb ()
        - swap_secondary_drm_fb ()
	  - secondary_gpu_state->gbm.next_fb_id = 0;
- meta_onscreen_native_flip_crtcs ()
  - meta_onscreen_native_flip_crtc ()
    - meta_gpu_kms_flip_crtc () gets called with fb_id = 0

This race was observed lost when running 'mutter --wayland' on a machine
with two outputs on Intel and one output on DisplayLink USB dock, and
wiggling around a weston-terminal window between the Intel and
DisplayLink outputs. It took from a second to a minute to trigger. For
testing with DisplayLink outputs Mutter also needed a patch to take the
DisplayLink output into use, as it would have otherwise been ignored
being a platform device rather than a PCI device.

Fix this race by first waiting for pending flips and only then
proceeding with the swap operations. This should be safe, because the
pending flips could have completed already before entering
meta_onscreen_native_swap_buffers_with_damage ().

6267732bec monitor-manager: use MonitorsConfig to track switch_config
When constructing MetaMonitorsConfig objects, store which type
of switch_config they are for (or UNKNOWN if it is not such
type of config).

Stop unconditionally setting current_switch_config to UNKNOWN when
handling monitors changed events. Instead, set it to the switch_config
type stored in the MonitorsConfig in the codepath that updates logical
state. In addition to being called in the hotplug case along the same
code flow that generates monitors changed events, this is also called
in the coldplug case where a secondary monitor was connected before
mutter was started.

When creating the default linear display config, create it as a
switch_config so that internal state gets updated to represent
linear mode when this config is used.

The previous behaviour of unconditionally resetting current_switch_config
to UNKNOWN was breaking the internal state machine for display config
switching, causing misbehaviour in gnome-shell's switchMonitor UI when
using display switch hotkeys. The lack of internal tracking when the
displays are already in the default "Join Displays" linear mode was
then causing the first display switch hotkey press to do nothing
(it would attempt to select "Join Displays" mode, but that was already
active).

8685de9607 input-settings: detect trackball using udev ID_INPUT_TRACKBALL
Previously, trackballs were detected based on the presence of the
substring "trackball" in the device name. This had the downside of
missing devices, such as the Kensington Expert Mouse, which don't have
"trackball" in their names.

Rather than depending on the device name, use the ID_INPUT_TRACKBALL
property from udev to determine whether or not to treat a device as a
trackball.

This adds a new function, `is_trackball_device`, to MetaInputEvents, and
eliminates the `meta_input_device_is_trackball` function.

f7af32a3ea renderer/native: Fallback to non-planar API if gbm_bo_get_handle_for_plane fails
Commit c0d9b08ef9 replaced the old GBM API calls
with the multi-plane GBM API. However, the call to gbm_bo_get_handle_for_plane
fails for some DRI drivers (in particular i915). Due to missing error checks,
the subsequent call to drmModeAddFB[2] fails and the screen output locks up.

This commit adds the missing error checks and falls back to the old GBM API
(non-planar) if necessary.

v5: test success of gbm_bo_get_handle_for_plane instead of errno

This commit adopts solution proposed by Daniel van Vugt to check the return
value of gbm_bo_get_handle_for_plane on plane 0 and fall back to old
non-planar method if the call fails. This removes the errno check (for
ENOSYS) that could abort if mesa ever sets a different value.

4d465eac08 monitor: Use current monitor mode to check whether active
For historical reasons meta_monitor_is_active() checked whether it is
active by checking whether the main output have a CRTC assigned and
whether that CRTC has a current mode. At a later point, the MetaMonitor
got its own mode abstraction (MetaMonitorMode), but
meta_monitor_is_active() was never updated to use this.

An issue with checking the main output's CRTC state is that, if there is
some CRTC mode combination that for some reason isn't properly detected
by the MetaMonitorMode abstraction (e.g. some tiling configuration not
yet handled), meta_monitor_is_active() would return TRUE, even though no
(abstracted) mode was set. This would cause confusion here and there,
leading to NULL pointer dereferences due to the assumption that if a
monitor is active, it has an active mode.

Instead, change meta_monitor_is_active() to directly check the current
monitor mode, and log a warning if the main output still happen to have
a CRTC with a mode assigned to it. This way, when an not undrestood CRTC
mode combination is encountered, instead of dereferencing NULL pointers,
simply assume the monitor is not active, which means that it will not be
managed or rendered by mutter at all.

1bf2eb95b5 renderer/native: Choose first EGL config for non-GBM backends
Commit 712ec30cd9 added the logic to only
choose EGL configs that match the GBM_FORMAT_XRGB8888 pixel format.
However, there won't be any EGL config satisfying such criteria for
non-GBM backends, such as EGLDevice.

This change will let us choose the first EGL config for the EGLDevice
backend, while still forcing GBM_FORMAT_XRGB8888 configs for the GBM
one.

516fb524cb cursor-render/native: Realize hw cursor lazilly
Where to realize a hardware cursor depends on where on the screen it
will be displayed. For example it only needs buffers for the cursor
plane on a certain GPU if it overlaps with a monitor that is connected
said GPU.

Previously, we were too eager with uploading the cursor plane buffers,
which in effect resulted in the secondary GPU always being woken up
when changing the cursor, even though the cursor plane would actually
never be set unless the pointer cursor was moved to a monitor connected
to the secondary GPU. These wake-ups caused noticable stuttering; thus
by uploading the buffers more lazilly, the stuttering is avoided.

f2dea5d139 renderer-native: Remove no_add_fb2
drmModeAddFB2 allows userspace to specify a real format enum on
non-ancient kernels, as an improvement over the legacy drmModeAddFB
which derives format from a fixed depth/bpp mapping.

As an optimisation, Weston used to decide at the first failure of
drmModeAddFB2 that the ioctl was unavailable: as non-existent DRM
ioctls return -EINVAL rather than -ENOSYS or similar, bad parameters are
not distinguishable from the ioctl not being present.

Mutter has also implemented the same optimisation for dumb framebuffers,
which potentially papers over errors for the gain of avoiding one ioctl
which will rapidly fail on ancient kernels. Remove the optimisation and
always use AddFB2 where possible.

0b3a1c9c31 monitor-manager: Find active monitor when deriving global scale
When deriving the global scale directly from the current hardware state
(as done when using the X11 backend) we are inspecting the logical
state they had prior to the most recent hot plug. That means that a
primary monitor might have been disabled, and a new primary monitor may
not have been assigned yet.

Stop assuming a primary monitor has an active mode before having
reconstructed the logical state by finding some active monitor if the
old primary monitor was disabled. This avoids a crash when trying to
derive the global scale from a disabled monitor.

Centering the pointer at startup causes undesired behaviour if

centering the pointer at startup in that case will get the

The ResetIdletime API can be used instead of an "XTest" binary to
programmatically reset the idle time, as if the user pressed a button on

This is necessary since we stopped using the XSync extension to monitor

clutter code ignores "Core Events" as generated by XTest.

This patch will require minimal changes to gnome-settings-daemon's power
test suite so that "key press" idletime resets are triggered through
this D-Bus interface rather than through XTest and a roundtrip through

67917db45f wayland: Use cursor position in logical monitor
When using two monitors size by side with different scales, once the
cursor moves from one output to another one, its size changes based on
the scale of the given output.

Changing the size of the cursor can cause the cursor area to change
output again if the hotspot is not exactly at the top left corner of the
area, causing the texture of the cursor to change, which will trigger
another output change, so on and so forth causing continuous surface
enter/leave event which flood the clients and eventually kill them.

Change the logic to use only the actual cursor position to determine if
its on the given logical monitor, so that it remains immune to scale
changes induced by output scale differences.

6f59e4858e renderer/native: Don't use modifiers to import linear DMA buffer
When the buffer modifier is DRM_FORMAT_MOD_LINEAR, we can use the
old code path. That means not specifying any modifier parameter.

It was an issue when the primary GPU was creating a linear GBM surface
and that a secondary GPU (not supporting modifiers) was trying to
import it. It was failing because the driver could not use the
import_modifiers extension even though it could in theory easily
import the buffer.

aec85281ba native/renderer: Retrieve the right modifiers set for each GPU
We were retrieving the supported KMS modifiers for all GPUs even
though what we really need to intersect between these sets of
modifiers:

1) KMS supported modifiers for primary GPU if the GPU is used for
   scanout;

2) EGL supported modifiers for secondary GPUs (different than the
   primary GPU used for rendering);

3) GBM supported modifiers when creating the surface (already
   taken care of by gbm_surface_create_with_modifiers());

54dcff3aa2 backends: Monitor changes in active tools' settings
So the changes can be instantly applied while the tool is in proximity.
Before we would just do it on proximity-in, which doesn't provide a
good look&feel while modifying the tool settings in g-c-c.

ac502c921d backends/x11: wacom pressure curve is a 32-bit property
The property has been 32 bits since around 2011 and has not changed, mutter
expects it to be 8 bits. The mismatch causes change_property to never
actually change the property.

86ab3878e7 renderer/x11: Enable GPU memory purge error extension if available
This was done by the clutter X11 backend before prior to introducing
MetaRenderer, but during that work, enabling of said extension was lost.
Let's turn it on again.

d092e913d6 gpu-kms: Don't add outputs without modes
There seems to be a kernel race when one disconnects an external
monitor connected to a DisplayPort via a USB-C adapter. The race
results in a connector being reported as connected, but without any
modes supported.

This had the side effect that we tried to set a preferred mode to
the first listed mode, but as no modes were available, we instead tried
to dereference the first element of a NULL array, causing a
segmentation fault.

Mitigate this by skipping adding output if no supported modes are
advertised and the output doesn't support scaling, while moving the
fallback path for calculating a preferred output mode to after possibly
adding the common modes, to avoid the unvolentary NULL dereference.

57f55d486d backends/x11: Preserve XI1 XDevice throughout ClutterInputDevice lifetime
Opening and closing the device may result into XI2 grabs being cut short,
resulting into pad buttons being rendered ineffective, and other possible
misbehaviors. This is an XInput flaw that fell in the gap between XI1 and
XI2, and has no easy fix. It pays us for mixing both versions, I guess...

Work this around by keeping the XI1 XDevice attached to the
ClutterInputDevice, this way it will live long enough that this is not
a concern.

Investigation of this bug was mostly carried by Peter Hutterer, I'm just
the executing hand.

6be56de140 backends/x11: Fix time-comparison bug causing hang
A comparison in translate_device_event() does not account for the fact
that X's clock wraps about every 49.7 days.  When triggered, this causes
an unresponsive GUI.

Replace simple less-than comparison with XSERVER_TIME_IS_BEFORE macro,
which accounts for the wrapping of X's clock.
