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()

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.

libweston: make wl_output point to weston_head
The user data of a wl_resource representing a wl_output protocol object
used to be a pointer to weston_output. Now that weston_output is being
split, wl_output more accurately refers to weston_head which is a single
monitor.
Change the wl_output user data to point to weston_head.
weston_output_from_resource() is replaced with
weston_head_from_resource().
This change is not strictly necessary, but architecturally it is the
right thing to do. In the future there might appear the need to refer to
a specific head of a cloned pair, for instance.

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.

- Do not send wp_presentation_feedback.sync_output events for multiple
wl_output globals in weston_presentation_feedback_present().

libweston: properly orphan wl_output resources
Remove the wl_resource in the head's resource list when we are
removing the wl_output global. We sent global removal events to clients,
the resources should become dummies until clients reap them. Reset user
data so that clients triying to use dummy objects don't hit e.g. a freed
head pointer.
This fixes a theoretical issue: if an enabled output is disabled and
then gets enabled again, mode changes and wl_surface.enter/leave would
still attempt to use the dummy objects. If a client destroyed a dummy
object, we don't have the destructor to remove it from the resource
list, and libweston would hit freed memory.

cms-colord: find a good head
The 'head' member of 'struct weston_output' is going to go unused and
then disappear, so stop using it and find a head from the proper list.
However, this leaves a problem in cms-colord: if you have multiple
monitors driver with the same CRTC, what do you say to the color
management system? The monitors could be different, but all the color
LUTs etc. are in the CRTC and are shared, as is the framebuffer.
Do the simple hack here and just use whatever head happens to be the
first in the list.
The warning is printed in get_output_id(), because if heads are added or
removed while the output is enabled, the id could change.

Currently a single head is automatically created with an output, and
outputs are only ever created as connected and destroyed on

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.

- Change the callback function pointer into a wl_signal. The API is
changed and renamed.
v6:
- fix a typo
- add comment in weston_pending_output_coldplug()

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.

weston: migrate DRM to head-based output API
Migrate the DRM frontend to use the simple head-based output
configurator, maintaining the exact same features and semantics as
before.
This is an intermediate step. It is unoptimal to create a weston_output
just to turn it off, but the libweston implementation and the DRM
backend require it for now. In the future, the DRM frontend will get its
own configurator that does not create useless weston_outputs and
supports clone mode by attaching multiple heads to the same
weston_output. Clone mode is not yet supported by libweston/DRM.
Until we remove the need to create a weston_output just to turn it
"off", that is, disable it, we will hit simple_head_enable() for heads
we have already disabled. As long as the DRM-backend conversion to the
head-based API is not complete, attempting to create an output for a
head again would lead to a crash. This problem does not exist right now,
but it will after the patch "compositor-drm: start migration to
head-based output API". Therefore, check if the head we are about to
process is already attached, and do nothing if so. DRM outputs set to
"off" are the only ones legitimately hitting this condition.
This is the last frontend migrated, wet_set_pending_output_handler() is
deleted as dead code.

- Add the workaround in simple_head_enable().

libweston: cancel idle_repaint on output destroy
If the idle_repaint() callback has been scheduled when a weston_output
gets destroyed, the callback will hit use-after-free. I have encountered
this when migrating the wayland backend to the head-based API, using
--sprawl, and closing/disconnecting one of the parent compositor
outputs.
Store the idle_repaint callback source, and destroy it in
weston_output_release(), ensuring we don't get a stale call to
start_repaint_loop later.

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.

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()

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".

compositor-drm: start migration to head-based output API
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.
Clones are not yet supported, hence max is defined to 1.
This unfortunately introduces some temporary code that will be revomed
later, but seems to be necessary to avoid a single big patch.

libweston: allow attaching heads to enabled outputs
Move the responsibility of ensuring the head will work in the enabled
output to the backends.
A compositor cannot enable an output without heads, and removing the
last head from an output automatically disables the output, so attaching
a new head to an enabled output is only possible for clone mode.
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.
Also ensure a global is created for the head when attached to an enabled
output, and log it.

compositor-drm: move connector fields into drm_head
Move the connector related fields from drm_output to the drm_head. A
drm_head represents a connector for now.
The code in drm_head_create() to update connector data, monitor
information, etc. is moved into a new function. This will be useful when
DRM-backend starts creating heads for all connectors regardless of their
connection status and will need to update them on hotplug events.
While incurring the churn to move several fields into struct drm_head,
also refactor out drm_head_assign_connector_info(). This function is
needed later when drm_heads will exist regardless of connected status,
as every hotplug event will need to update the state of all connectors.
At that point we will also start handling connector changes that do not
go through an intermediate disconnected state. This refactoring is
trivial enough to be in this patch to reduce the total amount of changes
to be reviewed.

compositor-drm: allocate CRTC on enable()
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
find a suitable CRTC. We might want to cache the resources somewhere,
but that is it topic for another patch.

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.

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.

libinput: allow evdev_device_set_output(dev, NULL)

Previously, the listener was left "used", which would mean the next call

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.

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.

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.

pixman,drm: do not composite previous damage

composite the current damage into shadow, but the copy to hw buffer

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

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.

desktop-shell: handle NULL output in get_output_work_area()
This is a tentative crash fix for a case where there are no
enabled weston_outputs at all.
Let get_output_work_area() return a zero area if the given output is
NULL. If there is no output, there is no area. Unfortunately we cannot
return "no position" but have to use 0,0 instead.
In send_configure_for_surface(), this causes a maximized surface to
receive width=0 and height=0 in the configure event, which means the
client is free to choose the size. There is no correct size to send for
maximizing for no output.
In constrain_position(), this has no effect. The interactive move of a
surface is restricted to not go below the panel, so even if a user
managed to move a surface without an output, it just prevents the
surface moving beyond y=0.
In weston_view_set_initial_position(), get_output_work_area() will not
be called with NULL output anyway.
In set_maximized_position(), this makes it behave as if the output was
at 0,0 which is the default position of the first output.

Fix a crash when unlocking or unconfining a pointer
In GNOME (but not in Weston), if a window loses focus, the client first receives
the focus event, then the unlock/unconfine event. This causes toytoolkit to

- Run weston-confine
- Click the window
- Alt-Tab away from it

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.

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

Commit a30e29af2e4d0ad6fc476ae7cc13c4cad5119217 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
touch-ups either. Code inspection says it would confuse the
idle-inhibit counting, and it could probably confuse clients as well.
Hence, just drop unmatched touch-ups.

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".

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

As Weston should not hardcode system specifics, the actual permanent

clients: add a new touchscreen calibrator
The new calibrator uses weston_touch_calibration protocol extension and
provides the following features:
- chooses the physical touch device to be calibrated by DEVPATH or by
the output/head name; device enumeration provided
- the compositor ensures the calibrator window is shown in the correct
position and size
- no matter how wrong the old calibration is, the touch events will
always arrive in the application
- the calibration is complete, not incremental; the received touch
events are guaranteed to be unmodified
- computes a libinput style calibration matrix directly, not the
WL_CALIBRATION format
- supports multiple touch devices: calibrate one device at a time, and
show user feedback on touching a wrong device instead of recording bad
data
- uses four touch point samples: three to compute the calibration, and
one to verify the calibration is roughly correct
- consistent exit codes
- upload the new calibration into the server after successful
and verified calibration
Due to using special touchscreen calibration protocol extension, this
application cannot be tested without touch input from the compositor.
Practically all of the above mentioned are unlike how the old
calibrator client worked.

Rename the IVI tests to be more consistent with the others, and invert
the naming of plugin/client to make it slightly more clear what's going

the local binaries.
As a side-effect, weston.ini ivi-shell-user-interface no longer needs to

weston: support clone mode on DRM-frontend
Add a new output section key "same-as" for configuring clone mode. An
output marked "same-as" another output will be configured identically to
the other output.
The current implementation supports only CRTC sharing for clone mode.
Independent CRTC clone mode cannot be supported until output layout
logic is moved from libweston into the frontend and libweston's damage
tracking issues stemming from overlapping outputs are solved.
Quite a lot of infrastructure is needed to properly configure clone
mode. The implemented logic allows easy addition of independent CRTC
clone mode once libweston supports it. The idea is that wet_layoutput is
the item to be laid out and all weston_outputs a wet_layoutput
contains show exactly the same area of the desktop.
The configuration logic attempts to automatically fall back to creating
more weston_outputs when all heads do not work under the same
weston_output. For now, the fallback path ends with an error message.
Enabling a weston_output is bit complicated, because one needs to first
collect all relevant heads, try to attach them all to the weston_output,
and then back up head by head until enabling the weston_output succeeds.
A new weston_output is created for the left-over heads and the process
is repeated.
CRTC-sharing clone mode is the most efficient clone mode, offering
synchronized scanout timings, but it is not always supported by
hardware.
v10:
- rebased trivial conflicts in man page
- switch to gitlab issue URL
v9:
- replace weston_compositor_set_heads_changed_cb() with
weston_compositor_add_heads_changed_listener()
- remove workaround in simple_head_enable()
v6:
- Add man-page note about cms-colord.
- Don't create an output just to turn it off.

desktop-shell: fix output removal for background/panel
When the compositor has multiple outputs (not clones) and one of them is
removed, the ones remaining to the right will be moved to close the gap.
Because reflowing the remaining outputs happens before removing the
wl_output global, we get the new output x,y before the removal. This
causes us to consider the remaining output immediately to the right of
the removed output to be a clone of the removed output whose x,y don't
get updated. That will then hit the two assertions this patch removes.
The reason the assertions were not actually hit is because of a
compositor bug which moved the remaining outputs in the wrong direction.
The next patch will fix the reflow, so we need this patch first to avoid
the asserts.
Remove the assertions and hand over the background and panel if the
"clone" does not already have them. If the clone already has them, we
destroy the unnecessary background and panel.

man: add description for specifying modes with aspect-ratio in weston.ini
This patch adds information about the new resolution-format that can
be specified by a user in weston.ini to select a CEA mode. CEA defines
timing of a video mode, which is considered as a standard for
HDMI certification and compliance testing. It defines each and every
parameter, of a video mode, like h/vactive,h/vfront h/vback etc.,
including aspect-ratio information. The drm layer, specifies the
aspect-ratio information in user-mode flag bits 19-22. For the non-CEA
modes a value of 0 is given in the aspect-ratio flag bits. Each
CEA-mode is identified by a unique, Video Identification Code (VIC).
For example, VIC=4 is 1280x720@60 aspect-ratio 16:9.
This mode will be different than a non-CEA mode 1280x720@60 0:0.
The new mode-format helps to differentiate between the CEA and
non-CEA modes, by letting user specify aspect-ratio along with other
paremeters: mode=widthxheight@rr ratio.
This helps when certification testing is done, in tests like 7-27,
the HDMI analyzer applies a particular CEA mode, and expects the
applied mode to be with exactly same timings, including the
aspect-ratio and VIC field.

compositor-drm: Add aspect-ratio parsing support
The flag bits 19-22 of the connector modes, provide the aspect-ratio
information. This information can be stored in flags bits of the
weston mode structure, so that it can used for setting a mode with a
particular aspect-ratio.
Currently, DRM layer supports aspect-ratio with atomic-modesetting by
default. For legacy modeset path, the user-space needs to set the
drm client cap for aspect-ratio, if it wants aspect-ratio information
in modes.
This patch:
- preserves aspect-ratio flags from kernel video modes and
accommodates it in wayland mode.
- uses aspect-ratio to pick the appropriate mode during modeset.
- changes the mode format in configuration file weston.ini to
accommodate aspect-ratio information as:
WIDTHxHEIGHT@REFRESH-RATE ASPECT-RATIO
The aspect-ratio can take the following values :
4:3, 16:9, 64:27, 256:135.
v2: As per recommendation from Pekka Paalanen, Quentin Glidic,
Daniel Stone, dropped the aspect-ratio info from wayland protocol,
thereby avoiding exposure of aspect-ratio to the client.
v3: As suggested by Pekka Paalanen, added aspect_ratio field to store
aspect-ratio information from the drm. Also added drm client
capability for aspect-ratio, as recommended by Daniel Vetter.
v4: Minor modifications and fixes as suggested by Pekka Paalanen.
v5: Rebased, fixed some styling issues, and added aspect-ratio
information while printing weston_modes.
v6: Moved the man pages changes to a different patch. Minor
reorganization of code as suggested by Pekka Paalanen.

e2e80136334f fixed the same issue as df573031d0ba in a different way.

The former commit adds this checking inside prepare_scanout_view: if the

compositor-drm: Only check final co-ordinates for overlay scaling
When considering a view for placement into an overlay plane, we
previously checked that the buffer's transform and scale were identical
to the output's, and that there were no transformations applied.
We now use a more consistent set of checks through
drm_plane_state_coords_for_view. This checks the complete transformation
chain, allowing only translation and scaling; at the end, we check if
the total buffer -> surface -> view -> output chain requires scaling or
rotation, and disallow it if so.
This allows scaling in the cases where the transformation chain cancels
itself out to produce a 1:1 buffer -> output pixel scale.
An erroneously disallowed case is where buffer -> view -> output
rotations cancel each other out; we prevent a view from being on an
overlay plane if rotation is involved at all. Fixing this would require
a complete analysis of the overall transformation matrix.

Now that we have a helper to fill the plane state co-ordinates from a

We now explicitly check that the view fills exactly the fullscreen area
and nothing else. We then use the new helper to fill out the plane state
values, and do further checks against the filled-in co-ordinates, i.e.
that we're not trying to show an offset into the buffer, or to scale the
image.
This now allows cases where the buffer -> surface -> view -> output
transform chain cancels each other out for scaling: previously, we would
never consider a buffer for scanout unless its scale matched the
output's. We now only look at the final result of the buffer -> output
transformation, to check that this does not result in translation or
scaling.

plane state hanging; this makes them all consistent.

compositor-drm: Don't set fb->size for non-dumb buffers
When creating a drm_fb from client (wl_buffer/dmabuf), gbm_surface, or
client buffers, set fb->size to 0. The size member is only used for dumb
buffers, where we mmap the whole buffer, and need the size recorded to
later pass to munmap.
Determining the full size of multi-planar buffers is difficult, as
auxiliary planes are not guaranteed to have a (height*stride)
allocation, e.g. if they are subsampled or if they do not contain pixel
data at all but, e.g., compression information. Single-plane tiled
buffers also often pad the buffer allocation to a multiple of tile
height, making our existing calculation incorrect.
Though it does no harm to record incorrect information, it also does
no good as we never use it; remove it in order to avoid any confusion.

compositor-drm: Support plane IN_FORMATS
The per-plane IN_FORMATS KMS property describes the format/modifier
combinations supported for display on this plane. Read and parse this
format, storing the data in each plane, so we can know which
combinations might work, and which combinations definitely will not
work.
Similarly to f11ec02cad40 ("compositor-drm: Extract overlay FB import to
helper"), we now use this when considering promoting a view to overlay
planes. If the framebuffer's modifier is definitely not supported by the
plane, we do not attempt to use that plane for that view.
This will also be used in a follow-patch, passing the list of modifiers
to GBM surface allocation to allow it to allocate more optimal buffers.

compositor-drm: Use GBM modifier API
Now that we collect information about which modifiers are supported for
KMS display, and are able to create KMS framebuffers with modifiers,
begin using the modifier-aware GBM API.
Client buffers from dmabuf already store multi-plane and modifier
information into drm_fb. Extend this to drm_fb_get_from_bo(), used for
wl_buffer, cursor, and gbm_surface buffers. wl_buffer buffers should by
convention not require modifiers. Cursor buffers must not require
modifiers, as they should be linear. Prior to this patch, GBM buffers
must have been single-planar, and able to used without explicitly naming
modifiers.
Using gbm_surface_create_with_modifiers allows us to pass the list of
modifiers acceptable to KMS for scanout to GBM, so it can allocate
multi-planar buffers or those which are otherwise only addressible with
modifiers. On platforms supporting and preferring modifiers for scanout,
this means that the gbm_bos we get from our scanout surface need to use
the extended API to query multiple planes, offsets, modifiers, etc.

compositor-drm: Disallow overlapping overlay planes
The scanout plane strictly stacks under all overlay planes, and the
cursor plane above. However, the stacking of overlay planes with respect
to each other is undefined.
We can control the stacking order of overlay planes with the zpos
property, though this significantly complicates plane assignment. In the
meantime, simply disallow assigning a view to an overlay, when it
overlaps another view which is already on an overlay. This ensures
stacking order is irrelevant, since the planes never intersect each
other.

compositor-drm: Use sprites_are_broken for scanout plane
When the sprites_are_broken variable is set, do not attempt to promote
client surfaces to the scanout plane.
We are currently assuming that every client buffer will be compatible
with the scanout plane, but that is not the case, particularly with more
exotic tiled/compressed buffers. Once we promote the client buffer to
scanout, there is no going back: if the repaint fails, we do not mark
this as failed and go back to repaint through composition.
This permanently removes the ability for scanout bypass when using the
non-atomic path. Future patches lift the restriction when using atomic
modesetting, as we can actually test and ensure that the view is
compatible with scanout.

compositor-drm: Add modes to drm_output_propose_state
Add support for multiple modes to drm_output_propose_state. Currently we
intend to operate in three modes: planes-only (no renderer buffer,
client buffers in planes only), mixed-mode (promote client buffers to
planes where possible, falling back to the renderer where not), and
renderer-only (no plane usage at all).
We want to use the first (planes-only) mode where possible: it can avoid
us having to allocate buffers for the renderer, and it also gives us the
best chance of the optimal configuration, with no composition. In this
mode, we walk the scene looking at all views, trying to put them in
planes, and failing as soon as we find a view we cannot place in a
plane.
In the second mode, rather than failing, we assign those views which
cannot be on a plane to the renderer, and allow the renderer to
composite them.
In the third mode, planes are not usable, so everything but the cursor
goes to the renderer. We will use this when we cannot use the planes-only
mode (because some views cannot be placed in planes), but also cannot
use the 'mixed' mode because we have no renderer buffer yet. Since we
walk the scene graph from top to bottom, using atomic modesetting we
will determine if planes can be promoted in mixed mode by placing a
renderer buffer at the bottom of the scene, placing a cursor buffer if
applicable, then testing if we can add overlay planes to this mode.
Without a buffer from the renderer, we cannot do these tests, so we push
everything through the renderer and then switch to mixed mode on the
next repaint.
This patch implements the mixed and renderer-only modes (previously
differentiated only by the sprites_are_broken flag), with the
planes-only mode being left for a later patch.

drm_output_propose_state is only concerned with preparing, testing, and

compositor-drm: Add planes-only mode to state proposal
Add a new mode, which attempts to construct a scene exclusively using
planes. This is a building block for incrementally testing and
constructing state: in the plane-only mode, we test the state exactly
once, when we have constructed a full set of planes and want to know if
it works or not.
When using the renderer, we need to incrementally test views one by one
to see if they will work on planes, falling back to the renderer if not.
This test is different, since the scanout plane will be occupied by the
renderer's buffer. Testing using the renderer or client buffers may have
completely different characteristics, so we need two passes: first,
constructing a state with only planes and testing if that succeeds,
falling back later to a mixed renderer/plane mode which tests
incrementally.
This implements the first mode, and preferentially attempts to use it.

compositor-drm: Incrementally test plane states in mixed mode
In the plane-only mode, we try to place every view on a hardware plane,
and fail if we can't do this. This requires a full walk of the scene
graph to come up with a complete configuration in order to be able to
test.
In mixed mode, we know at least some visible views will fail to be
promoted to planes and must be composited via the renderer. In order to
still use some planes where possible, we use atomic modesetting's
test-only mode to incrementally test configurations.
We know that the renderer output will always be visible, and because it
is the renderer, that it will be occupying the scanout plane underneath
everything else. The actual renderer buffer doesn't materialise until
after assign_planes, because it cannot know what to render until then.
However, in order to test whether a configuration is valid, we need the
renderer buffer in the scanout plane. For testing, we fake this by
temporarily stealing the old buffer - if it seems sufficiently
compatible - and placing it in the state we construct. This is used to
test whether or not a renderer buffer will work with the addition of
overlay planes.
Doing this incremental testing will allow us to enable plane usage for
atomic by default, since we know ahead of time that our chosen plane
configuration will work.

compositor-drm: Allow scanout plane to be occluded by overlay
a0f8276fe814 ("compositor-drm: Disallow overlapping overlay planes") was
a little too pessimistic in rejecting occluded views. Whilst it
correctly prevented overlay planes from occluding each other, it also
prevented overlay planes from occluding the scanout plane.
This is undesirable: the primary/scanout plane is specified to stack
strictly below all overlay planes, so there is no need to reject a plane
from consideration for scanout due to being occluded by an overlay
plane.
Shift the check downwards so it only applies to overlay rather than
scanout planes.
