9711fd9850 libweston: fix output reflow on removal
This is regression apparently introduced in
0de859ede4, which accidentally swapped the
sign of 'delta_width' in the original call site. If one removes an
output, the remaining outputs on the right are getting moved even
further to the right.

The outputs to the right should be moved to the left instead, to close
the gap left by the removed output.

4381040dc6 compositor-fbdev: detect the first fb device in the seat
This adds a function to detect the first framebuffer device in the
current seat. Instead of hardcoding /dev/fb0, detect the device
with udev, favoring the boot_vga device, and falling back to the
first framebuffer device in the seat if there is none. This is very
similar to what compositor-drm does to find display devices

e03c111e4e tests: Don't rely on build directory layout
Rather than having a hardcoded dependency on the build-directory layout,
use an explicit module-map environment variable, which rewrites requests
for modules and helper/libexec binaries to specific paths.

Pekka: This will help with migration to Meson where setting up the paths
according to autotools would be painful and unnecessary.

Emre: This should also help setting up the test suite after a
cross-compile.

Pekka: A caveat here is that this patch makes it slightly easier to load
external backends by abusing the module map. External backends are
specifically not supported in libweston.

83630983ad libweston: implement touch calibration protocol
This implements a new global interface weston_touch_calibration, which
allows one client at a time to perform touchscreen calibration. This
also implements the calibrator window management.

A client asks to calibrate a specific physical touch device (not a
wl_seat which may have several physical touch devices aggregated).
Libweston grabs all touch devices and prevents normal touch event
handling during the calibation sequence.

API is added to enable this new global interface, but it not yet called
by anything. Since the implementation allows clients to grab touch devices
arbitrarily, it is not enabled by default. The compositor should take
measures to prevent unexpected access to the interface.

A client may upload a new calibration to the compositor. There is a
vfunc to allow the compositor to reject/accept it and save it to
persistent storage. The persistent storage could be a udev rule
setting LIBINPUT_CALIBRATION_MATRIX, so that all display server would
load the new calibration automatically.

Co-developed by Louis-Francis and Pekka.

v2:
- use struct weston_point2d_device_normalized
- use syspath instead of devpath
- wrong_touch was renamed to invalid_touch
- rename weston_touch_calibrator::cancelled to calibration_cancelled
- send invalid_touch on out-of-bounds touch-down
- cancel touch sequence and send invalid_touch on motion going
  out-of-bounds
- rename calcoord_from_double() to wire_uint_from_double()
- send bad_coordinates error in touch_calibrator_convert()
- conversion results in 0,0 if cancelled

c4689ff1d0 input: introduce touch event mode for calibrator
In addition to the normal touch event processing mode, introduce a new
mode for calibrating a touchscreen input device.

In the calibration mode, normal touch event processing is skipped, and
the raw events are forwarded to the calibrator instead. The calibrator
is not yet implemented, so the calls will be added in a following patch.

To switch between modes, two functions are added, one for entering each
mode. The mode switch happens only when no touches are down on any touch
device, to avoid confusing touch grabs and clients. To realise this, the
state machine has four states: prepare and actual state for both normal
and calibrator modes.

At this point nothing will attempt to change the touch event mode.

The new calibrator mode is necessary, because when calibrating a
touchscreen, the touch events must be routed to the calibration client
directly. The touch coordinates are expected to be wrong, so they cannot
go through the normal focus surface picking. The calibrator code also
cannot use the normal touch grab interface, because it needs to be able
to distinguish between different physical touch input devices, even if
they are part of the same weston_seat. This requirement makes
calibration special enough to warrant the new mode, a sort of "super
grab".

Commit a30e29af2e introduced the code to
deal with a touchscreen with touches already down when Weston starts
using it. It fixed the touchpoint counting problem.

However, Weston still should not forward or process the unmatched

Hence, just drop unmatched touch-ups.

f406253d3c libweston: introduce notify_touch_normalized() and doc
notify_touch_normalized() is an extended form of notify_touch(), adding
normalized touch coordinates which are necessary for calibrating a
touchscreen.

It would be possible to invert the transformation and convert from
global coordinates to normalized device coordinates in input.c without
adding this API, but this way it is more robust against code changes.

Recovering normalized device coordinates is necessary because libinput
calibration matrix must be given in normalized units, and it would be
difficult to compute otherwise. Libinput API does not offer normalized
coordinates directly either, but those can be fetched by pretending the
output resolution is 1x1.

Anticipating touch calibration mode, the old notify_touch() is renamed
into a private process_touch_normal(), and the new
notify_touch_normalized() delegates to it.

Co-developed by Louis-Francis and Pekka.

v2:
- introduce struct weston_point2d_device_normalized
- rename notify_touch_cal() to notify_touch_normalized()
- remove WESTON_INVALID_TOUCH_COORDINATE

6ef59c9843 input: introduce weston_touch_device
Introduce weston_touch_device for libweston core to track individual
touchscreen input devices. A weston_seat/weston_touch may be an
aggregation of several physical touchscreen input devices. Separating
the physical devices will be required for implementing touchscreen
calibration. One can only calibrate one device at a time, and we want to
make sure to handle the right one.

Both backends that support touch devices are updated to create
weston_touch_devices. Wayland-backend provides touch devices that cannot
be calibrated, because we have no access to raw touch coordinates from
the device - calibration is the responsibility of the parent display
server. Libinput backend provides touch devices that can be calibrated,
hence implementing the set and get calibration hooks.

Backends need to maintain an output pointer in any case, so we have a
get_output() hook instead of having to maintain an identical field in
weston_touch_device. The same justification applies to
get_calibration_head_name.

Also update the test plugin to manage weston_touch_device objects.

Co-developed by Louis-Francis and Pekka.

26ded94aa0 pixman: make shadow buffer optional
Add a flag to pixman-renderer for initializing the output with a shadow
framebuffer. All backends were getting the shadow implcitly, so all
backends are modified to ask for the shadow explicitly.

Using a shadow buffer is usually beneficial, because read-modify-write
cycles (blending) into a scanout-capable buffer may be very slow. The
scanout framebuffer may also have reduced color depth, making blending
and read-back produce inferior results.

In some use cases though the shadow buffer might be just an extra copy
hurting more than it helps. Whether it helps or hurts depends on the
platform and the workload. Therefore let the backends control whether
pixman-renderer uses a shadow buffer for an output or not.

acf50c3d96 pixman,drm: do not composite previous damage
Pixman-renderer uses a single internal shadow buffer. It is enough to
composite the current damage into shadow, but the copy to hw buffer
needs to include the previous damage because of double-buffering in
DRM-backend.

This patch lets pixman-renderer do exactly that without compositing also
the previous damage on DRM-renderer.

Arguably weston_output should not have field previous_damage to begin
with, because it implies double-buffering, which e.g. EGL does not
guarantee. It would be better for each backend explicitly always provide
any extra damage that should be copied to hw.

27cc4816ae compositor-drm: rewrite crtc picking for clone mode
To support shared-CRTC clone mode, the chosen CRTC needs to support
driving all the attached connectors. Replace the old algorithm with a
new one that takes into account all associated connectors.

Ideally it should use possible_clones mask to check which encoders (and
therefore connectors) actually can be in a cloned set. However, the DRM
documentation says about possible_clones and possible_crtcs masks both:
"In reality almost every driver gets this wrong."
- https://01.org/linuxgraphics/gfx-docs/drm/gpu/drm-kms.html#c.drm_encoder

Looking at a target device and its kernel where clone mode is desired,
possible_clones is indeed self-conflicting and would not allow cloning
at all. Therefore the implemented algorithm replaces the checking of
possible_clones with luck. It even goes out of its way to find any CRTC
for a configuration, even if not advertised by the kernel as not
supported.

Libweston would need infrastructure to allow trial-and-error CRTC
allocation: rather than picking one CRTC in advance and do or die, it
should try all available CRTCs one by one. Unfortunately that is not yet
possible, so this patch implements what it can. It is also the DRM
upstream opinion that trial-and-error with ATOMIC_TEST would be the way
to go.

Unlike the old algorithm, the new algorithm prefers routings that were
in place when Weston started instead of when enabling an output. When
you never temporarily disable an output, this makes no difference.

1bbf58ff58 libinput: do not switch output associations on disable
If an input device is associated to an output that then gets disabled,
there is no case where associating to a different output would be
correct.

The output association is used for absolute positioned input devices,
and an input device like a touchscreen cannot ever be automatically
valid for more than one possible output - the touchscreen display
device.

Therefore do not automatically reassing implicitly associated input
devices to another output. This removes some log spam on shutdown.

In fact, if there can be more than one output at any time, absolute
input devices must be explicitly configured to associate with the
correct output, or the results are essentially undefined in any case.

8dc6db8c76 libweston: require connected heads for input devices
The use case driving this change is a clone mode setup, where the user
is hotplugging or unplugging a cloned touchscreen. Even if the output
and head are force-enabled, the touch device should still follow the
connector connection status. If there is no video signal for the
touchscreen (disconnected connector), then the touch input should be
ignored as well.

When the output is force-enabled, we need to trigger
output_heads_changed from connector status changes. If the head or
output are not force-enabled, the compositor will likely attach and
detach the head as appropriate. In clone mode, the attach or detach
needs to trigger output_heads_changed directly. In other cases, it may
be handled through the output getting enabled or disabled which are
different signals.

fd02efbc84 libinput: use head names for output matching
Associating input devices with weston_outputs by the output name fails
when one output has several heads. We need to match against head names
instead of output names to be able to find all names.

This fixes touchscreen output association in shared-CRTC clone mode when
outputs or input devices appear or disappear.

Even though notify_output_create() is called only when new outputs
appear, the implementation is prepared to also remove output
associations. This will be handy in the future when this function will
handle also head detaching from an output that remains enabled.

98d50cc311 libinput: allow evdev_device_set_output(dev, NULL)
Removing the output association from an evdev_device is more than just
setting the pointer to NULL, one also needs to remove the destroy
listener and flag the destroy listener as unused (notify == NULL).

evdev_device_set_output() can already remove associations, so let it
also handle an assignment to NULL output.

Fix notify_output_destroy() to handle removing an association correctly.
Previously, the listener was left "used", which would mean the next call
to evdev_device_set_output() would have wl_list_remove()'d, accessing
freed memory. This could be triggered by having a touchscreen with a
specified output association, and unplugging then re-plugging the

ed51b62416 libinput: deprecate WL_CALIBRATION
The udev property WL_CALIBRATION is an old way of giving Weston a
touchscreen calibration matrix. It is Weston-specific.

The recommended way of setting up a calibration is to use the udev
property LIBINPUT_CALIBRATION_MATRIX, which libinput will load
automatically and therefore applies to all libinput using display
servers and applications.

The syntax of WL_CALIBRATION and LIBINPUT_CALIBRATION_MATRIX is
different as well: WL_CALIBRATION uses pixels as the translation part
units, which makes the values depend on the output resolution.
LIBINPUT_CALIBRATION_MATRIX on the other hand uses normalized units.

d2e6242e3c compositor-drm: create heads for all connectors
In previous patches, all the appropriate fields from drm_output have
been moved into drm_head, and resource allocation has been moved away
from drm_output creation. It is time to throw the switch: this patch
disconnects the drm_output and drm_head lifetimes.

Previously a drm_output was created for a connected connector and
destroyed on disconnection. A drm_head was tied to the drm_output
lifetime just to accommodate the head-based output configuration API
temporarily.

Now all connectors will get a head created regardless of their
connection status. Heads are created and destroyed as connectors appear
and disappear (MST), not when they get connected or disconnected. This
should allow the compositor to force-enable a disconnected connector.

An "empty" drm_output is created with weston_backend::create_output()
hook. This now follows the intent of the head-based output configuration
API.

On hotplug events, all connectors' information is updated regardless of
their connection status changes. It is theoretically possible for a
monitor to change without going through a disconnected state in between.

A drm_output needs a CRTC only when it is in use. Allocating a CRTC on
creation of drm_output will reserve the CRTC regardless of whether the
output is actually used or not. This may cause creating other
drm_outputs to fail if there are not enough CRTCs.

Instead, allocate the CRTC on drm_output enable() time. A drm_output
will have a valid CRTC only while it is enabled.

This allows us to create drm_output objects arbitrarily and without a
head assignment, which is required by the head-based output API for the
backends. The assigned heads will be known only at enable() time.

Now drm_output_enable() has to call drmModeGetResources() to be able to

as every hotplug event will need to update the state of all connectors.

A compositor cannot enable an output without heads, and removing the

Backends headless, rdp, and x11 forbid clone mode by not having an
attach_head hook implemented; fbdev and wayland explicitly deny clone
mode. Only the DRM backend is affected by this change and even that not
yet because MAX_CLONED_CONNECTORS is 1 in the DRM backend.

Hook up the libweston facing head-based output API by introducing struct
drm_head, but leave it as a fake so that members can be migrated in
pieces in follow-up patches.

The DRM backend continues to create an output for each connected
connector only, and during output creation it also creates a drm_head
for it. This allows it to pretend it supports the head-based output API
as long as there is only one head per output ever attached.

create_output callback is fake, it will only look up the existing
drm_output by the head name.

c80e954123 compositor-wayland: migrate to head-based output API
Follow the standard pattern used in the headless and x11 backend
migration, but also cater for the two other backend modes: --sprawl or
fullscreen-shell, and --fullscreen.

Stops relying on the implicit weston_output::head.

Unlike other backends, this uses the attach_head hook to do the
required head setup that is not possible to do without an output, but
must be done before weston_output_enable(). This also requires the
detach_head hook for the one case where the user attaches a --fullscreen
head and then detaches it without enabling the output.

It is a little awkward to fully initialize heads as late as attach, but
aside from the --sprawl/fullscreen-shell case, there is not really a way
to know the head properties without creating the parent wl_surface and
configuring it.

Heads/outputs created for parent outputs now have distinct names instead
of all being called "wlparent".

2305812296 compositor-fbdev: migrate to head-based output API
Implement the head-based output API in this backend, and stop relying on
the implicit weston_output::head.

The split between fbdev_head and fbdev_output is somewhat arbitrary.
There is no hotplug or unplug, and there is always 1:1 relationship.
Struct fbdev_screeninfo could have been split as well, but it would not
have made much difference.

I chose fbdev_output to carry the mmap details (buffer_length is now
duplicated here), and fbdev_head to carry the display parameters and
device node path. The device node identifies the head, similar to a
connector.

The backend init creates a head. The compositor uses it to create an
output. Libweston core attaches the head automatically after creating
the output. The attach hook is a suitable place to set up the video
modes on the output as they are dictated by the head, it would be too
late at enable() time.

v7:
- use name argument instead of hardcoded "fbdev" in
  fbdev_output_create()

55916d54ce compositor-fbdev: make re-enable less drastic
Destroying the whole output in reenable would cause list walk
corruption: the loop over output_list in session_notify() is not using
wl_list_for_each_safe so output removal would break it.

Creating a new output is also problematic as it needs the compositor to
configure it, but that probably saved us from another list walk failure:
adding the new output to be list while walking the list, possibly
causing it to be destroyed and re-created ad infinitum.

Instead of a complete destroy/create cycle, just do our internal
disable/enable cycle. That will re-open the fbdev, re-read the
parameters, re-create hw_surface, and reinitialize the renderer output.

A problem with this is if fbdev_set_screen_info() fails. We do read the
new parameters, but we don't communicate them to libweston core or old
clients.

However, it is hard to care: to trigger this path, one needs to
VT-switch to another fbdev app which changes the fbdev parameters. That
is quite difficult as VT-switching has been broken for a good while for
fbdev-backend, at least with logind. Also fbdev_set_screen_info() would
have to fail before one should be able to tell something is wrong.

The real reason behind this patch, though, is the migration to the
head-based output API. Destroying and re-creating an output really does
not fit that design. Destroying and re-creating a head would be better,
but again not testable in the current state.

992a8cb38c libweston: new head-based output management API
Introduce the API for users (compositors) to create an output from a
head, attach and detach heads, and destroy outputs created this way.
This also adds the backend-facing API to libweston.

In the new API design, a backend creates heads, and the compositor
chooses one or more heads (clone mode) to be driven by an output.
In the future backends will be converted to not create outputs directly
but only in the new create_output hook.

The user subscribes to a heads_changed hook and arranges heads into
outputs from there.

Adding the API this way will allow frontends (main.c) and backends to be
converted one by one. This adds compatiblity paths in
weston_compositor_create_output_with_head() and weston_output_destroy()
so that frontends can be converted first to call these, and then
backends can be converted one by one to the new design. Afterwards, the
compatibility paths will be removed along with weston_output::head.

Currently heads can be added to a disabled output only. This is less
than ideal for clone mode hotplug and should be improved on later.

v4: Remove the wl_output global on head detach if output is enabled.

37e6c9e537 libweston: add heads_changed_signal
Add a hook for compositors to get a callback when heads are added or
their connection status changes, to which compositors likely want to
react to by enabling or disabling outputs (API for that to be added
later).

As many head changes as possible should be coalesced into a single
heads_changed call. Therefore the callback is made from an idle task.
This anticipates a future atomic output configuration API, where the
global output configuration is tested and set atomically instead of one
by one.

weston_pending_output_coldplug() needs to manually execute the
heads_changed call so that initial outputs are created before any
plugins get their start-up idle tasks ran. This is especially important
for ivi-shell which does not support output hotplug, and for tests to
guarantee the expected outputs.

v8:
- Change the callback function pointer into a wl_signal. The API is
  changed and renamed.

object, we don't have the destructor to remove it from the resource

7cdbabee9a libweston: introduce weston_output::head_list
The intention is that in the future backends will dynamically allocate
weston_heads based on the resources they have. The lifetime of a
weston_head will be independent of the lifetime of a weston_output it
may be attached to. Backends allocate objects derived from weston_head,
like they currently do for weston_output. Backend will choose when to
destroy a weston_head.

For clone mode, struct weston_output gains head_list member, which is
the list of attached heads that will all show the same framebuffer.
Since heads are growing out of weston_output, management functions are
added.

Detaching a head from an enabled output is allowed to accommodate
disappearing heads. Attaching a head to an enabled output is disallowed
because it may need hardware reconfiguration and testing, and so
requires a weston_output_enable() call.

As a temporary measure, we have one weston_head embedded in
weston_output, so that backends can be migrated individually to the new
allocation scheme.

  wl_output globals in weston_presentation_feedback_present().

1b9bf598a5 libweston: move wl_output to weston_head
The wl_output protocol interface exposes things like monitor make,
model, sub-pixel layout and physical dimensions. Obviously wl_output is
meant to represent a monitor.

The abstraction of a monitor is weston_head. Therefore move the wl_output
global and the bound resources list into weston_head.

When clone mode gets implemented in the future, this means that monitors
driven by the same CRTC will still be represented as separate wl_output
globals. This allows to accurately represent the hardware.

Clone mode that used separate, not frame-locked, CRTCs to drive two
monitors as clones would necessarily also be exposed as separate
wl_output since they have different timings.

01f60211b2 libweston: introduce weston_head
In order to support clone modes, libweston needs the concept of a head
that is separate from weston_output. While weston_output manages buffers
and the repaint state machine, weston_head will represent a single
monitor. In the future it will be possible to have a single
weston_output drive one or more weston_heads for a clone mode that
shares the framebuffers between all cloned heads.

All the fields that are obviously properties of the monitor are moved
from weston_output into weston_head.

As moving the fields requires one to touch all the backends for all the
assingments, introduce setter functions for them while we are here. The
setters are identical to the old assignments, for now.

As a temporary measure, weston_output embeds a single head. Also the
ugly casts in weston_head_set_monitor_strings() will be removed by a
follow-up patch.

Libweston major version is bumped, because weston_output struct layout
is changed.

v7:
- Bump libweston major version.

v6:
- adapt to upstream changes in weston_output_set_transform()

3f83937414 compositor-wayland: Ignore pointer enter on destroyed surface
Due to race conditions, it is (vanishingly unlikely but) possible to

72e183bd2b input: never set keyboard focus without wl_resource
Do not attempt to set keyboard focus to a surface that has no
wl_resource. The destroy listener hangs off the wl_resource, so if that
is not present, nothing will clean up the pointer when the
weston_surface gets destroyed and it goes stale.

As keyboard_focus_resource_destroyed() sets the focus to NULL, this
patch should be enough to guarantee that the keyboard focus surface will
always have a wl_resource.

I have confirmed the added branch in weston_keyboard_set_focus() can be
hit, but doing so is hard.

My test case has weston/x11 with two outputs, and weston/wayland
--sprawl running on top of that, then closing the parent compositor
output windows one by one. Sometimes it hits, often it does not. Having
the window closing animation enabled may help to hit it.

8d6e14c991 compositor-wayland: handle wl_keyboard.enter(NULL)
Destroying an output (wl_surface) can race against the parent compositor
sending wl_keyboard.enter. When this race is lost, wayland-backend
receives wl_keyboard.enter with a NULL wl_surface for the surface it
just destroyed.

Handle this case by ignoring such enter events. Since it is
theoretically possible to follow enter with key events, drop those too.

The modifiers event is sent before enter, so we cannot drop that on the
same condition.

wl_keyboard.leave handler seems to already handle the NULL focus case,
but there is a question if the notify_keyboard_focus_out() call should
be avoided.

This patch fixes a hard to reproduce crash. I was running weston/x11
with two outputs, and weston/wayland --sprawl inside that, then closing
the parent compositor windows one by one. Sometimes it would trigger
this crash.

b678befb6e gl-renderer: Create a high priority context
EGL_IMG_context_priority allows the client to request that their
rendering be considered high priority. For ourselves, this is important
as we are interactive and any delay in our rendering causes input-output
jitter; a less than smooth user interactive. So if the driver supports
setting the context priority, try and create our EGLContext as high
priority. The driver may reject our request due to system restrictions,
in which case it will fallback to normal priority, but if successful it
will reschedule our rendering and all of its dependencies to execute
earlier, especially important when the GPU is being hogged by background
clients.

the complete absence of the ioctl, as the return here is -EINVAL rather
than -ENOTTY.

A check for whether or not the format is valid has been replaced with an

operations belong together: state_invalid is required for the new unused

This does not hinder initial turning off of outputs, because on
compositor start-up, state_invalid is initialized to true, making calls
to drm_output_disable() for non-enabled outputs a no-op.

Previous changes already ensure that if a compositor does not explicitly
enable an output, the CRTC and connector will be turned off even without

cb2d8836c0 compositor-drm: let repaint cycle disable crtcs
Rather than smashing the state to disable a CRTC immediately, just
delegate that to the normal repaint cycle by setting state_invalid =
true. drm_pending_state_apply() will pick up the unused_crtcs.

A caveat here is that we have no enabled outputs at all, we will never
enter repaint, and so CRTCs do not actually get turned off until we get
at least one output to drive.

However, this should help the problem reported here:
https://lists.freedesktop.org/archives/wayland-devel/2018-January/036713.html
Arguably it is better to leave an output spuriously on in rare cases
rather than fail modeset completely in somewhat more common cases.

My personal motivation for this change is that it helps if we later move
CRTC allocation to output enable/deinit instead of create/destroy,
because then the CRTC will not be available here for initial turn-off as
the output has not been enabled to begin with.

a08512f464 compositor-drm: Move repaint state application to flush
Split repaint into two stages, as implied by the grouped-repaint
interface: drm_output_repaint generates the repaint state only, and
drm_repaint_flush applies it.

This also moves DPMS into output state. Previously, the usual way to
DPMS off was that repaint would be called and apply its state, followed
by set_dpms being called afterwards to push the DPMS state separately.
As this happens before the repaint_flush hook, with no change to DPMS we
would set DPMS off, then immediately re-enable the output by posting the
repaint. Not ideal.

Moving DPMS application at the same time complicates this patch, but I
couldn't find a way to split it; if we keep set_dpms before begin_flush
then we break DPMS off, or if we try to move DPMS to output state before
using the repaint flush, we get stuck as the repaint hook generates an
asynchronous state update, followed immediately by set_dpms generating a
synchronous state update.

In drm_output_update_complete, the *_pending flags are cleared
before any of the pending actions are taken; this ensures that the
actions cannot recurse.

6020f478c7 compositor-drm: Disable unused CRTCs/connectors
If we have an unused CRTC or connector, explicitly disable it during the
end of the repaint cycle, or when we get VT-switched back in.

This commit moves state_invalid from an output property to a backend
property, as the unused CRTCs or connectors are likely not tracked by
drm_outputs. This matches the mechanics of later commits, where we move
to a global repaint-flush hook, applying the state for all outputs in
one go.

The output state_invalid flag originally provoked full changes on output
creation (via setting the flag at output enable time) and session enter.

For the new-output case, we will not have any FB in output->state_cur,
so we still take the same path in repaint as if state_invalid were set.
At session enter, we preserve the existing behaviour: as
start_repaint_loop will fail when state_invalid is set, all outputs will
be scheduled for repaint together, and state_invalid will not be cleared
until after all outputs have been repainted, inside repaint_flush.

- Removed a check that should never have been commited.

Changes since v2:
- Request UINT32_MAX items instead of 2048, to avoid cutting valid
  icons.
- Strengthen checks against malformed input.
- Handle XCB_PROPERTY_DELETE to remove the icon.
- Schedule a repaint if the icon changed.

Changes since v3:
- Keep the previous Cairo surface until the new one has been
  successfully loaded.
- Use uint32_t for cardinals.  Unsigned is the same type except on
  16-bit machines, but uint32_t is clearer.

8564a0d109 compositor: Implement runtime output transform changes
Up to now we could set the transform only on output initialization.
However, on certain situations(like tablets and convertible laptops),
screen orientation can change while the compositor is running and thus
the need for change of the output transform arises.

When the transform changes, we must update the output geometry,
output->region and output->previous_damage, as well as send this change
to clients. We also have to check whether any of the pointers are inside
the output which is being rotated. If this is the case, they are moved
to the new center, because otherwise the pointer is stuck outside of the
screen ans "lost" to the user.

What is more, after calling this function compositors should check if
any view is now outside of the screen and move it according to their
wish.

import_simple_dmabuf function in gl-renderer.c compares

DRM_FORMAT_MOD_INVALID is equal to ((1ULL<<56) - 1).
Therefore, modifer 0 is accepted as valid. Then, the function
checks support for eglQueryDmaBufModifiersEXT.
If it is not supported import_simple_dmabuf function is returning
NULL.

This patch sets the modifier attribute to DRM_FORMAT_MOD_INVALID

b040974398 gl-renderer: Set pitch correctly for subsampled textures
zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
plane, but wl_shm only takes a single pitch parameter; the pitch for
secondary planes must be inferred.

Multi-plane sub-sampled textures have partial width/height, e.g.
YUV420/I420 has a full-size Y plane, followed by a half-width/height U
plane, and a half-width/height V plane.

GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the
pitch for secondary planes by the subsampling factor. gl-renderer was
not doing this, and instead just using the (larger) stride provided by
the client for all planes in the buffer.

Fix gl-renderer to divide pitch by the subsampling factor when uploading
from subsampled SHM buffers into GL textures, also dividing co-ordinates
when doing offset partial uploads.

Tested with:
  $ gst-launch-1.0 videotestsrc ! waylandsink

2b3c97d560 compositor-wayland: fix damage coordinates with pixman renderer
Damage coordinates are in global coordinate space, and they need to
be translated to local coordinate space so multiple outputs can work.

This path now matches the similar path in the X11 backend.

This patch fixes the appearance of multiple windows in the parent
compositor. Previously, all windows except the one with nested output
position 0,0 would have their damage for the parent wl_surface always
fall outside of the wl_surface, save the decorations which were handled
separately. If the parent compositor was Weston/GL, this would lead to
the output area remaining black as partial GL texture uploads would
practically never update the texture. If the parent compositor was
Weston/pixman, the parent windows would not update on screen unless
something else caused the area to be repainted.

4dab58343b compositor-wayland: fix mode_list corruption on --sprawl
The wayland-backend with --sprawl is one way to trigger
wayland_output_create_for_parent_output(), which intends to find a mode
from the parent mode list and use it. Calling wayland_output_set_size()
initialized an embedded struct weston_mode and inserts that into the
mode list. Then the assignment output->mode = *mode; corrupts the
mode_list by overwriting the link entry. This leads to an endless loop
in bind_output() in compositor.c.

Fix this by manually doing the setup that wayland_output_set_size() did
and do not call it.

As a side effect, it now relays the parent compositor's physical output
size to our own clients. It no longer smashes the refresh rate either.

b07de934cc compositor-wayland: avoid recursive dispatch with wl_outputs
Calling wl_display_roundtrip() from within a Wayland event handler means
we will re-enter event dispatch, that is, it will lead to recursive
dispatch. Even if libwayland-client was safe, this would lead to
unexpected code paths: the first event handler function has not returned
when other event handler functions may get called. In this particular
case it maybe didn't hurt, but it's still a fragile pattern to use.

Replace the wl_display_roundtrip() with a manual sync callback to do the
work.

This does not break the wayland-backend initialization sequence, because
sprawl_across_outputs was set only after the roundtrip to ensure
wl_registry globals have been received so the code would not have been
hit anyway, and weston_backend_init() also has a second roundtrip that
ensures the per wl_output events have been received before continuing.

For wayland-backend output hotplug the change is insignificant because
it will only delay the output creation a bit, and the parent outputs are
not processed anywhere in between.

a51e71fbf0 compositor-fbdev: simplify FB destroy/unmap/disable
Rename fbdev_frame_buffer_destroy() to fbdev_frame_buffer_unmap()
because that is what it does. Adding the destruction of hw_surface in it
makes it the perfect counterpart to fbdev_frame_buffer_map() which
simplifies the code.

fbdev_frame_buffer_map() can no longer call that, so just open-code the
munmap() there. It is an error path, we don't really care about
failures in an error path.

The error path of fbdev_output_enable() is converted to call
buffer_unmap() since that is exactly what it did.

fbdev_output_disable() became redundant, being identical to
fbdev_frame_buffer_unmap().

Invariant: output->hw_surface cannot be non-NULL without output->fb
being non-NULL. hw_surface wraps the mmapped memory so cannot exist
without the mmap.

7da9a3802f libweston: set backend pointer earlier
Change all backends to set the core backend pointer early.

This is necessary for libweston core to be able to access the backend
vfuncs before the backend init function returns. Particularly,
weston_output_init() will be needing to inspect the backend vfuncs to
see if the backend has been converted to a new API. Backends that create
outputs as part of their init would fail without setting the pointer
earlier.

For consistency, all backends are modified instead of just those that

d7e351189e libweston: ensure backend is not loaded twice
Check and ensure that a compositor can only load one backend
successfully. If a backend fails to load, it is theoretically possible
to try another backend. Once loading succeeds, only destroying the
compositor would allow "unloading" a backend.

If backend init fail, ensure the backend pointer remains NULL to avoid
calling into a half-loaded backend on e.g. compositor destruction.

ae6d35db14 libweston: rename weston_output_destroy() to weston_output_release()
'release' is a more appropriate name because the function does not free
the underlying memory. The main reason for this is that we need the name
weston_output_destroy() for new API that actually will free also the
underlying memory.

Since the function is only used in backends and external backends are
not a thing, this does not cause libweston major version bump, even
though it does change the ABI. There is no way external users could have
successfully used this function.

6f1866b3fa compositor-drm: set output make/model/serial once
This fixes a regression where monitor make and model would always be
advertised as "unknown" to Wayland clients. The EDID strings were parsed
at create_output_for_connector() time, but the fallback "unknown" values
were set in weston_drm_output_api::set_mode vfunc later. This made the
correct monitor info be shown in the log, but not sent to clients.

The purpose of the "unknown" assignments is to give fallback values in
case EDID is not providing them.

Fix all that by moving all setting of the make, model and serial into
create_output_for_connector(). These values cannot change afterwards
anyway. While at it, document find_and_parse_output_edid().

The ugly casts in create_output_for_connector() are required to silence
compositor warnings from ignoring const attribute. This is temporary,
and a future refactoring will get rid of the casts.

1580be68fd compositor-wayland: move output init into common, fix error path
Move the weston_output_init() call into wayland_output_create_common().
This avoids passing the name twice to different functions, and follows
the precedent set in "libweston: weston_output_init(..., +name)" for
calling init before accessing fields.

Since the error paths in wayland_output_create_for_parent_output() and
wayland_output_create_fullscreen() are now guaranteed to have

might be more to free than just the name.

26ac2e1218 libweston: weston_output_init(..., +name)
Add 'name' argument to weston_output_init(). This is much more obvious
than the assert inside weston_output_init() to ensure the caller has set
a field in weston_output first.

Now weston_output_init() will strdup() the name itself, which means we
can drop a whole bunch of strdup()s in the backends. This matches
weston_output_destroy() which was already calling free() on the name.

All backends are slightly reordered to call weston_output_init() before
accessing any fields of weston_output, except the Wayland backend which
would make it a little awkward to do it in this patch. Mind, that
weston_output_init() still does not reset the struct to zero - it is
presumed the caller has done it, since weston_output is embedded in the
backend output structs.

4270414549 libweston: move weston_output::mode_list init to core
Initialize the list in weston_output_init() instead of doing it
separately in each backend.

One would expect weston_output_init() to initialize all weston_output
members, at least those that are not NULL.

We rely on the set_size() functions to be called only once, as is
assert()'d. If set_size() becomes callable multiple times, this patch
will force them to be fixed to properly manage the mode list instead of
losing all members.

compositor-wayland.c is strange in
wayland_output_create_for_parent_output(): it first called
wayland_output_set_size() that initialized the mode list with a single
mode manufactured from width and height and set that mode as current.
Then it continued to reset the mode list and adding the list of modes
from the parent output, leaving the current mode left to point to a mode
struct that is no longer in the mode list and with a broken 'link'
element. This patch changes things such that the manufactured mode is
left in the list, and the parent mode list is added. This is probably
not quite right either.

df0e4b965f gl-renderer: Emit GPU rendering begin and end timeline timepoints
Use EGL fence sync objects to emit timepoints for the beginning and the
end of rendering on the GPU. The timepoints are emitted asynchronously
using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.

The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.

If timelining is inactive or the required EGL extensions are not
present, then GPU timepoint processing and emission are skipped.

Note that the GPU timestamps returned by sync files are in the
CLOCK_MONOTONIC clock domain, and are thus compatible with the
timeline timestamps (which also are in the CLOCK_MONOTONIC domain).

All planes being displayed have a framebuffer. What makes 'fb_plane'
special is that it's being displayed as the primary plane by KMS.

Previous patchsets renamed this to 'primary_plane' to match the KMS
terminology, namely the CRTC's base plane, which is controlled by
drmModeSetCrtc in the legacy API, and identified by PLANE_TYPE ==
"Primary" in the universal-plane API.

However, Weston uses 'primary_plane' internally to refer to the case
where client content is _not_ directly displayed on a plane, but
composited via the renderer, with the result of the compositing then
shown.

Rename to 'scanout_plane' as our least-ambiguous name, and document it a

7f340ff895 libweston: specify weston_output::enabled
It was ambiguous what this flag meant - it did not mean whether the
backend is considering this output to be enabled, because
weston_output_destroy() unsets it while deliberately not calling the
backend disable() vfunc.

Perhaps the most clear definition is with respect to the output's
assignment in the pending vs. enabled output lists. There is also a whole
bunch of variables that are allocated only when enabled is true.

Since the flag is related to the list membership, set and clear the flag
only when manipulating the lists.

Assert that weston_compositor_add_output() and
weston_compositor_remove_output() are not called in a wrong state.

v2:

weston_compositor_add_pending_output() is the point through which all

vfuns are essential for anything to be done with the output, so it makes

disabling.

Particularly the disable vfunc is rarely called, so this gets the check
better excercised.

f0ca79639e libweston: let add/remove_output handle the lists
A weston_output available to the compositor should always be either in
the list of pending outputs or the list of enabled outputs. Let
weston_compositor_add_output() and weston_compositor_remove_output()

This way weston_output_enable() does not need to remove and

manually re-add the output back to the pending list.

To make everything nicely symmetric and fix any unbalancing caused by
this:
- weston_output_destroy() explicitly wl_list_remove()s
- weston_compositor_add_pending_output() first removes then inserts, as
we have the assumption that the link is always valid, even if empty.

eca5cca561 Account for very large repaint window misses

This code only accounted for flips which missed their target by one
repaint window. If they miss by multiples of the repaint window, adjust
them until the next repaint timestamp is in the future. This will only
happen in fairly extreme situations, such as Weston being scheduled out
for a punitively long period of time. Nevertheless, try to help recovery

2cd87fe8d7 compositor-drm: Fix disabling cursor plane
commit a7cba1d4cd changed the way
the cursor plane is setup.  Previously it was pre-emptively set
disabled for the next frame, and that would be changed at next
frame time if the cursor plane was to be used.  It was changed
to be disabled at plane assignment time.

We disable the use of planes entirely by setting disable_planes to
a non-zero value, which bypasses all calls to assign_planes - so
if the plane was set-up in the previous frame it will retain its
state post-disable.

This leads to desktop zoom leaving the cursor plane in place when
it sets disable_planes.

This patch clears any stale cursor plane state from the redraw
handler if disable_planes is set so drm_output_set_cursor()
will do the right thing.

205c0a018c compositor-drm: Clean up page_flip_pending path
page_flip_pending is only be set when do a pageflip to a newly-rendered
buffer; if the flag is not set, we have landed in the start_repaint_loop
path where the vblank query fails, and thus we must pageflip to the same
buffer.

This test was not sufficient for what it was supposed to guard:
releasing framebuffers back. When using client-supplied framebuffers, it
is possible to reuse the same buffer multiple times, and we would send a
framebuffer-release event too early.

However, since we have a properly reference-counted drm_fb now, we can
just drop this test, and rely on the reference counting to prevent
too-early release of client framebuffers.

page_flip_pending now becomes exactly what the name suggests: a flag
which indicates whether or not we are expecting a pageflip event. Add
asserts here to verify that we never receive a pageflip event we weren't
expecting.

f30a18c1c3 compositor-drm: Introduce fb_last member
Previously, framebuffers were stored as fb_current and fb_pending.
In this scheme, current was the last buffer that the kernel/hardware had
acknowledged displaying: a framebuffer would be created, set as
fb_pending, and Weston would request the kernel display it. When the
kernel signals that the request was completed and the hardware had made
the buffer current (i.e. page_flip_handler / vblank_handler), we would
unreference the old fb_current, and promote fb_pending to fb_current.

In other words, the view is 'which buffer has turned to light?'.

This patch changes them to a tristate of fb_last, fb_current and
fb_pending, based around the kernel's view of the current state.
fb_pending is used purely as a staging area for request construction;
when the kernel acknowledges a request (e.g. drmModePageFlip returns 0),
the previous buffer is moved to fb_last, and this new buffer to
fb_current. When the kernel signals that the request has completed and
the hardware has made the buffer current, we simply unreference and
clear fb_last, without touching fb_current/fb_pending.

The view here is now 'which state is current in the kernel?'.

As all state changes are incremental on the last state submitted to the
kernel, even if the hardware has not yet been able to make it current,
this simplifies state tracking: all state submissions will always be
relative to fb_current, rather than the previous
(fb_pending) ? fb_pending : fb_current.

The use of fb_pending is strictly bounded between a repaint cycle
(including a grouped set of repaints) beginning, and those repaints
being flushed to the kernel.

fb_current will always be valid between an output's first repaint
flush, and when a disable/destroy request has been processed. For a
plane, it will be valid when a repaint cycle enabling that plane has
been flushed, and when a repaint cycle disabling that plane has been
flushed.

fb_last is only present when a repaint request for the output/plane has
been submitted, but not yet completed by the hardware.

This is the same set of constructs which will be used for storing
plane/output state objects in future patches.

2667e9e399 configure: replace HAVE_LIBDRM with BUILD_DRM_COMPOSITOR
HAVE_LIBDRM was used as a condition for the launcher infrastructure to
call libdrm.so functions. It was set by an independent test for libdrm,
which would silently continue if libdrm was not found. It was assumed
that if you enabled a feature that used libdrm at runtime, the test for
that feature would imply that HAVE_LIBDRM is also set. This was quite
subtle.

The only feature that actually uses libdrm.so at runtime is the DRM
backend. No other backend needs the libdrm calls in the launcher
infrastructure.

Therefore to simplify things, stop using HAVE_LIBDRM and use
BUILD_DRM_COMPOSITOR instead. If you enable the DRM compositor, you
automatically also get libdrm support in the launchers.

There are still things depending on LIBDRM_CFLAGS and LIBDRM_LIBS, so
the test cannot be removed completely.

compositor-wayland: Call set_window_geometry when using zxdg_shell_v6
This way Wayland compositors will be aware of Weston's
"visible bounds" (and ignore its shadows).

compositor-wayland: Check the return value of wayland_output_create_common
If wayland_output_create_common returns NULL, it means that
the output creation failed.

compositor-wayland: Refactor struct wayland_output::name usage
struct wayland_output::name was used but never initialized.
Also zxdg_toplevel_v6_set_title was only called for windowed outputs,
and some compositors let you see the client's name even when it is
fullscreen (GNOME Shell's Activities menu for example).

So rename struct wayland_output::name to struct wayland_output::title and
precompute it on wayland_output_create_common(), so it can be later used
on xdg's set_title and frame_create.

v2: Move zxdg_toplevel_v6_set_title() before the wl_surface_commit()
as per Quentin Glidic's suggestion.
