10a840c92d kms/impl-device: Handle NULL gamma updates
We should not ever get one right now, but if we do, a NULL update means
we bypass the gamma LUT.

863163cc6e cogl: Port Texture* away from CoglObject
- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one

Note we would still want to get rid of the _cogl_texture_init which is something
for the next commit

85885c6539 input-capture: Check barriers don't extend into nonexisting monitors
Create a fake monitor region right of the right-most monitor and if a
horizontal barrier extends into that region, fail the barrier. Barriers
are aligned on the top/left edge of the pixel so the most natural
barrier of (e.g. 0-1024) is also wrong - it's one pixel into the next
monitor.

Check this for nonexisting screens on the right too to avoid clients
suddenly failing when multiple monitors are present.

909cc6c240 renderer/native: Send modifiers even without AddFb2
When running headless, only the invalid modifiers are advertised.

That breaks with the NVIDIA proprietary driver which then rejects the
buffers created with the invalid modifier, and that kills Xwayland,
meaning that running Xwayland on top of a mutter based compositor
headless is not possible.

The reason the modifiers are not sent is because AddFb2 is not supported
when running headless.

Other compositors (weston, wlroots) would still send the modifiers even
without AddFb2, and Xwayland works fine on those compositors when
running headless.

Remove the requirement for AddFb2 to send the modifiers, so that
Xwayland can work fine on top of mutter headless with the NVIDIA
proprietary driver.

5d3e31a499 kms/impl-device: Inhibit real-time scheduling when mode setting
Certain kernel drivers can take an unreasonably long time to
complete mode setting operations. That excessive CPU time is charged
to the process's rlimits which can lead to the process getting killed
if the thread is a real-time thread.

This commit inhibits real-time scheduling around mode setting
commits, since those commits are the ones currently presenting as
excessively slow.

b1db87ae30 thread: Allow turning off rt scheduling for running thread
At the moment if a thread is made real-time there's no going back,
it stays real-time for the duration of its life.

That's suboptimal because real-time threads are expected by RTKit to
have an rlimit on their CPU time and certain GPU drivers in the kernel
can exceed that CPU time during certain operations like DPMS off.

This commit adds two new ref counted functions:

    meta_thread_{un,}inhibit_realtime_in_impl

that allow turning a thread real-time or normally scheduled. At the same
time, this commit stores the RTKit proxy as private data on the thread
so that it can be reused by the above apis.

A subsequent commit will use the new APIs.

23876efad3 renderer/native: Clear old pending mode sets when unsetting all modes
If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the
old pending mode sets and start fresh.

We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.

a4e1afc648 renderer/native: Fold mode unsetting into renamed unset_modes()
We had a function called "reset_modes()" on MetaRendererNative, but what
it expected to do was to unset all modes on all CRTCs. Despite this, it
had code to unset modes on unconfigured CRTCs, probably because it was
used for multiple things in the past.

Make this a bit easier to follow by renaming the function
"unset_modes()" and fold the function doing the unsetting into the
function itself.

ed06820035 kms/impl-device/atomic: Fix stack overflow
Intel has started to advertise big gamma LUT sizes on some hardware
because the hardware supports segmented LUTs. This means they have a lot
more precision at certain segments then others. The uAPI can't expose
this functionality meaningfully so they chose to expose a huge number of
TAPs to sample from to their segmented LUT.

This increase in uAPI LUT size resulted in stack overflows because we
allocated the LUT on the stack. This commit moves it to the heap
instead.

9b663f44e6 screen-cast/strieam-src: Fix stride and max buffer size calculation
1. Centralize stride calculation in one function.
2. For dmabufs query the stride instead of assuming a certain value.
3. For system memory buffers use the pixel format to calculate the
   stride.
4. Stop negotiating `SPA_PARAM_BUFFERS_size` and
   `SPA_PARAM_BUFFERS_stride`.

2. fixes an actual bug where we reported wrong max buffer sizes,
resulting in crashes in Gstreamer when doing area screencasts on AMD
GPUs.

The reasoning for 4. is that the values were possibly wrong for
dmabufs as the negotiation happens before we create any buffers.
Further more neither Mutter nor the common consumers required it.
The later either ignore the values (OBS), always accept (gstpipewiresrc)
them or calculate the exact same possibly wrong values (libwebrtc).

6fe1b3145f backends/native: Translate keycodes with xkb_key_state_get_one_sym()
There's two aspects from its documentation
(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
affecting us here:

1. "This function is similar to xkb_state_key_get_syms(), but intended for
    users which cannot or do not want to handle the case where multiple
    keysyms are returned (in which case this function is preferred)."

   We are indeed in that field, and have been for a long time.

2. "This function performs Capitalization Keysym Transformations."

   This is unlike the xkb_key_get_syms() function that we use, and
   convenient here for parity with X11 since it behaves exactly that
   way.

Fixes cases where the keysym for some keys is not properly capitalized
when caps lock is toggled, due to the output of capslock+key being
different from shift+key. An example of this is 'é' in french(azerty)
layout (bound to the '2' key). Even though shift+2 outputs '2',
capslock+é should output 'É'.

c4b9431bb2 screen-cast/stream: Pass redraw clip to stage watches instead of paint context
The virtual stream source with CURSOR_MODE_EMBEDDED uses
META_STAGE_WATCH_AFTER_PAINT as the callback for recording its frame. In
this stage of the paint though, there is no ClutterPaintContext anymore
(there only is a paint context during the paint, not afterwards).
The callback (actors_painted()) tries to get the redraw clip from the paint
context, and we end up with a NULL pointer crash.

We actually do still have a redraw clip at this point, so because everyone
uses the paint context to get the redraw clip anyway, just pass the redraw
clip to the stage watches directly.

483601844b backends/eis-client: Do not add device before adding EIS regions
When a device is added, libei does not allow adding additional regions
for that particular device, as it is already advertised to the EI
client.
As a result, mutter currently effectively only adds the first region to
a device, but not the others.
This makes input in multi monitor sessions only possible on one monitor,
as the EI client cannot look up the other regions, since they were not
advertised to it.

Fix this situation by not adding and resuming the device, when a shared
device is used.
Instead, for shared devices, always add all regions first, and then
after that, add and resume the device.

4ff54997b6 cursor-renderer/native: Create all view objects before realizing
Realizing a cursor will assume view related state objects are valid so
they can mark them as dirty. This assumption broke when there were a
scale changed that happened with multiple CRTCs, as we'd create view
object by view object as we realized the texture. Realizing the texture
would trigger a signal that had the handler assuming the validity of all
view objects, but if we only had gotten to the first, the second view
would not be there yet, thus we'd be doing a NULL pointer dereference.

Creating the view objects first, then handling the updating avoids this
problem by making the already done assumption valid on hotplugs.

The test case added tests exactly this series of events, and uses a
virtual monitor as a cheap trick to make the KMS CRTC based view the
first one, and an arbitrary view the second that previously had its view
object initialized too late.

4075847278 backends/native: Use correct constructor for CLUTTER_TOUCH_CANCEL events
We were using the generic constructor for BEGIN/UPDATE/END events, that
have more data than CLUTTER_TOUCH_CANCEL. Since that function checks for
the event type, we were awkwardly forwarding a NULL event here.

6427b5b1f6 backends/x11: Prevent uneven error traps init/deinit on GInitable failure
GInitable initialization is failable, currently, it may fail before error
traps are initialized, but error traps would be invariably deinitialized on
finalize() of the failed object. This results in an assert hit, on top of the
original failure to initialize the backend.

The libX11 error handlers are a pure client-side construct, and not a server
request, they just need XInitThreads() called to set up the library-side locks
protecting access to the global variable. This is done beforehand already at
meta_backend_x11_init(), so initialize the error traps around that time too.

379996a63e onscreen/native: Check frame_info for null in finish frame callback
While adjusting the monitor layout of my docked laptop, mutter got a
segfault while attempting to dereference the frame_info struct. This
happened on gnome-shell 44.4-1.fc38.

cogl_onscreen_peek_head_frame_info() just forwards the call to
g_queue_peek_head() which returns NULL in the event that the queue is
empty. If finish_frame_result_feedback() is expected to always be called
with a non-empty queue there's still a bug somewhere, but regardless
this API can legitimately return NULL so it should be checked for prior
to dereferencing.

e303551745 backend: Ignore events without source_device for pointer visibility
There can be events which don't not have source devices set on them, because
they are not backed by real hardware and rather generated by us, for example
IM events coming from the shell's OSK.

So don't assume all events have a source device in
update_pointer_visibility_from_event() and rather ignore those without one,
as we are only interested in events coming from "real hardware" here.

This fixes an issue where the mouse pointer would appear on devices without
any input from actual mice/touchpads on OSK key presses.

38cdaaf1f8 backends/eis-client: Use scroll source 'wheel' instead of 'unknown'
CLUTTER_SCROLL_SOURCE_UNKNOWN only generates continuous scroll events
and no discrete scroll events.
As a result, scrolling only works in applications, that support high
resolution scroll wheels, like GTK4 applications.
GTK3 applications, on the other hand, don't support high resolution
scroll wheel events, and such scrolling does not work in these
applications.

Fix this issue by using the scroll source CLUTTER_SCROLL_SOURCE_WHEEL.
Since commit 92a90774a4 ([0]),
CLUTTER_SCROLL_SOURCE_WHEEL generates discrete events to ensure that
scrolling in legacy applications still works.

If the deadline timer is disabled (like on nvidia-drm or when

`meta_kms_device_set_needs_flush` on every cursor movement. But some were
getting skipped if they coincided with page flips, which resulted in some
cursor movements failing to schedule the frame clock. This resulted in
unnecessary levels of frame skips when using lower frequency input devices

69fad154b9 eis: Use either standalone or shared devices for absolute input
Sometimes it makes no sense to have a shared pointer device, for example
when they have no set region occupying the global stage coordinate
space. This applies to for example window screen cast based pointer
device regions - they are always local to the window, and have no
position.

We do need shared absolute devices in some cases though, primarily
multi-head remote desktop, where it must be possible to keep a button
reliably pressed when crossing monitors that have their own
corresponding regions.

To handle this, outsource all this policy to the one who drives the
emulated input devices. Remote desktop sessions where the screen casts
correspond to specific monitors (physical or virtual), we need to make
sure they map to the stage coordinate space, while for window screencast
or area screencasts, we create standalone absolute pointer devices with
a single region each.

A MetaEisViewport represents an absolute region backend by e.g. a

corresponds to a viewport that has no neighbours, and a non-standalone,
which represents a region of a global coordinate space.

The reason for having non-standalone viewports is to allow to mirror the
logical monitor layout of a desktop, while the standalone are meant to
represent things that are not part of the logical monitor layout.

d24be90941 backends/native: Fix accounting of cursor overlay inhibition
We react on changes to has_hw_cursor, but always try to inhibit if
there is no cursor sprite. While this looks like a reasonable optimization
with the typical situation of one cursor renderer, it may fall into
inhibiting twice without knowing to unwind, e.g.:

1. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> inhibit
2. has_hw_cursor: FALSE, cursor_sprite: NULL -> inhibit
3. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> uninhibit, but once

And this may also result in the CLUTTER_PAINT_FLAG_NO_CURSORS flag
staying on for Tablet cursors, that (so far) always use overlay paths.
This results in invisible tablet cursors after using the mouse at
least once.

5a05b1a901 monitor-transform: Invert the behaviour of transform_point
Previously it transformed a physical CRTC coordinate to a logical desktop
coordinate. But current and future users of the function all require
conversion from logical coordinates to physical coordinates. We would have
had to always invert the transform parameter which is a waste of time when
we can instead just invert the function behaviour.

We also simplify the parameters to show both the point coordinate and the
area dimensions are potentially transformed.

215b91a2e6 screen-cast/src: Consider preferred format for stream
When creating a new stream, check if the preferred format is
different from the default (COGL_PIXEL_FORMAT_BGRX_8888). If
it is, then also include it in the list of potential formats
for the stream.

COGL_PIXEL_FORMAT_BGRX_8888 is still passed around as it's
both the default, and the fallback for when things go wrong.

When creating buffers, use the negotiated SPA format instead
of a hardcoded value. We leave it to PipeWire to figure out
what's the best format, since clients may not support the
preferred format of the stream.

Due to how chaotic things got, this commit also cleans up
the create_pipewire_stream() to use an auxiliary array of
SPA formats, which is then iterated on in order to generate
the format pods.

It is a bit backwards that events contain information about

specify in the ClutterEvent handling entrypoint the stage
that will handle the event.

As a first step, add this ClutterStage argument, even though
the information is still carried through the event in order to
keep satisfying calls to the getter function.

This entrypoint has been also renamed to clutter_stage_handle_event(),
so that its ownership/namespace is clearer.

112cca75e2 kms/impl-device: Remove deadline timer arming from queue_update()
queue_update() in a previous iteration was called in two situations:

 * A page flip was already pending, meaning if we would commit an
   update, it'd fail with EBUSY.
 * A update was marked as "always-defer" meaning it should only be
   processed from the deadline callback (would there be one). These were
   used for cursor-only updates.

In the latter, we had to arm the deadline timer when queuing a new
update, if it wasn't armed already, while in the former, we would
currently idle, waiting for the page flip callback. At that callback
would the deadline timer be re-armed again.

Since we're only handling the former now, we'll never need to arm the
timer again, so remove code doing so. The code removed were never
actually executed anymore, after the "always-defer" flag on updates was
removed.

b516b009fa kms/impl-device: Treat handling update as flushing
Primary plane updates were forgetting to do this in OnscreenNative, but
rather than do it for each post there we should simply do it for each
post.

This fixes cursor stutter in the fallback path (not using deadline timers)
where needs_flush_crtcs would remain populated but CRTC_NEEDS_FLUSH would
never be emitted, because handle_flush hadn't been called for the last
post.

This is safe as the current use of scheduled flushing is only for cursor
updates, and since cursor updates happen on the same thread as processing,
and due to the fact that we always use the most up to date cursor position
when flushing, we never risk leaving an old cursor state unflushed.

358c10de14 kms/cursor-manager: Only update cursor plane relevant device on mode set
When we see a mode set, the cursor manager will update all the cursor
planes so they are set correctly as part of the mode set. KMS updates
are always per-device, and what was wrong was that it didn't filter out
CRTCs on devices that wasn't part of the mode set.

192d6686cf backend/cogl-utils: Move, rename to cogl-drm-formats and clean up
1. Move into the new 'common' folder and build for Wayland as well
   so we will be able to share the code in follow-up commits.

2. Rename to cogl-drm-formats to make it more obvious that the format
   map is more than an utility these days.

3. Drop the unused CoglTextureComponents part (see also previous
   commit).

4. Move the map to the header, simplifying some future use-cases.

5. Sync formats with MetaWaylandBuffer and MetaWaylandDmaBufBuffer and
   also use newly introduced opaque formats where appropriate.
   This avoids duplicated code, ensures that new drm-formats added to
   the dmabuf protocol have an adequate representation in Cogl from which
   information like alpha support can be easily derived and finally
   ensures we don't crash if the mappings got out of sync.

6. Remove some likely untested formats. In case some of these are
   actually needed on certain hardware, we can test whether we got
   the correct mapping by also adding support for the corresponding
   wl_shm_format in MetaWaylandBuffer by extending the gradient test in
   https://gitlab.freedesktop.org/jadahl/wayland-test-clients

6841153ad7 tests/kms-device: Add test for scheduled no-ops
We can schedule an update from the cursor manager, but that doesn't mean
there will be an actual plane assignment changed at the time of the
update processing, since for example we might have "touched" a CRTC, but
already left it before the processing started, meaning we have nothing
to change after all.

Add a test case that checks that this works properly.

e52641c4b6 cursor-renderer/native: Replace HW cursor with KMS cursor manager
This removes the old hardware cursor management code and outsources it
to MetaKmsCursorManager. What the native cursor renderer still does,
however, is the preprocessing i.e. rotating/scaling cursor that wouldn't
otherwise be fit for a cursor plane.

The cursor DRM buffers are instead of being per cursor sprite now per
CRTC, meaning we don't need to stop doing hardware cursors if part of
the cursor is on an output that doesn't support it. This is why the
whole scale/transform code changed from being per GPU to per CRTC.

6d873036e0 Add KMS cursor manager
This new manager object intends to take over management of the cursor
plane from the native cursor renderer. It's API is intended to be used
from the main thread, except for the _in_input() function, but mainly
operates in the KMS context, i.e. the KMS thread.

It makes use of an "update filter" that is called before each
MetaKmsUpdate is turned into a atomic KMS commit or a set of legacy
drmMode*() API calls. When the cursor position has been invalidated,
it'll assign the cursor plane in the filter callback, using an as up to
date as possible pointer position as the source for the cursor plane
position.

Cursor updates from the input thread schedules updates for the affected
CRTCs which will cause the filter to be run, potentially for cursor-only
commits.

27ed069766 kms/impl-device: Add deadline based KMS commit scheduling
This makes it possible to post KMS updates that will always defer until
just before the scanout deadline. This is useful to allow queuing cursor
updates where we don't want to post them to KMS immediately, but rather
wait until as late as possible to get lower latency.

We cannot delay primary plane compositions however, and this is due to
how the kernel may prioritize GPU work - not until a pipeline gets
attached to a atomic commit will it in some drivers get bumped to high
priority. This means we still need to post any update that depends on
OpenGL pipelines as soon as possible.

To avoid working on compositing, then getting stomped on the feet by the
deadline scheduler, the deadline timer is disarmed whenever there is a
frame currently being painted. This will still allow new cursor updates
to arrive during composition, but will delay the actual KMS commit until
the primary plane update has been posted.

Still, even for cursor-only we still need higher than default timing
capabilities, thus the deadline scheduler depends on the KMS thread
getting real-time scheduling priority. When the thread isn't realtime
scheduled, the KMS thread instead asks the main thread to "flush" the
commit as part of the regular frame update. A flushing update means one
that isn't set to always defer and has a latching CRTC.

The verbose KMS debug logging makes the processing take too long, making
us more likely to miss the deadline. Avoid this by increasing the
evasion length when debug logging is enabled. Not the best, but better
than changing the behavior completely.
