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
could hit an issue.

Libweston core will take care of resetting the backend pointer to NULL
in case of error since "libweston: ensure backend is not loaded twice".

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
weston_output init'd, call weston_output_destroy() appropriately. There
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).

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.

In doing this, the gymnastics required to exact the CRTC ID the plane
was last on when making a disabling drmModeSetPlane call have been
removed; specifying the CRTC is not necessary when disabling a plane.
(The atomic API goes a step further, mandating it be zero.)

acd71fb0af compositor-fbdev: fix start-up assertion
Fixes the failure to start with fbdev-backend:

weston: /home/pq/git/weston/libweston/compositor.c:4733: weston_compositor_add_pending_output: Assertion `output->disable' failed.

The disable hook was completely unimplemented, and the regression was
caused by e952a01c3b
"libweston: move asserts to add_pending_output()".
It used to work because Weston never tried to explicitly disable the
fbdev output, but now it is hitting the assert.

Fix it by tentatively implementing a disable hook. It has not been
tested to work for explicit disabling, but it does solve the regression.

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

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.

5bb8f58fd2 compositor-drm: Rename current/next FB members
'next' is used as a framebuffer which has either been rendered but not
had a configuration request (pageflip or CRTC set) applied to it, or
when for a framebuffer that has had configuration requested but not
applied (delayed pageflip where the event has not been applied).

'current' is used as the last framebuffer for which we know
configuration has been fully applied, i.e. CRTC set executed or pageflip
requested and event received.

Rename these members to fb_current and fb_pending, doing some small
reordering of drm_output whilst in the vicinity.

e42568313c compositor-drm: Use drm_fb for cursor buffers
Now that we have better types in drm_fb, use it for cursor buffers as
well. This gives us easier refcounting for our cursors, as well as a
unified buffer-destruction path.

Currently this makes no difference, as the KMS legacy cursor update API
uses GEM names directly, and never touches DRM FBs. However, the cursor
plane becomes a regular KMS plane under atomic, at which point we
require DRM FBs.

Take the opportunity to move to drm_fb ahead of time.

6e7a961d43 compositor-drm: Refcount drm_fb
Sometimes we need to duplicate an existing drm_fb, e.g. when
pageflipping to the same buffer to kickstart the repaint loop. To handle
situations like these, and simplify resource management for dumb and
cursor buffers, refcount drm_fb.

drm_fb_get_from_bo has a path where it may reuse a drm_fb, if the BO has
been imported and not released yet. As drm_fb_unref now relies on actual
refcounting (backed up by asserts), we add a balancing drm_fb_ref() to
the path where we return a reused drm_fb.

This calls drm_output_release_fb before the images are reallocated in

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.

05df8c16ec Change boolean repaint_scheduled to quad-state enum
repaint_scheduled is actually cleverly a quad-state, disguised as a
boolean. There are four possible conditions for the repaint loop to be
in at any time:
  - loop idle; no repaint will occur until specifically requested, which
    may be never (repaint_scheduled == 0)
  - loop schedule to begin: the loop was previously idle, but due to a
    repaint-schedule request, we will call the start_repaint_loop hook
    in the next idle task
  - repaint scheduled: the compositor has definitively scheduled a
    repaint request for this output, which will occur in fixed time
  - awaiting repaint completion: the backend has not yet signaled
    completion of the last repaint request, and the compositor will not
    schedule another until it does so

All but the first condition were previously conflated as
repaint_scheduled == 1, but break them out into separate conditions to
aid clarity, backed up by some asserts.

On startup, we cannot lock on to the repaint timer because it is unknown
to us. We deal with this by claiming that the moment of entry into the
repaint loop is the moment a frame returned, causing finish_frame to
delay our initial repaint to (refresh_time - repaint_delay), typically
around 9ms of utterly wasted time.

Add an explicit stamp == NULL, to determine that we are just beginning
our repaint loop, that the timings are in fact totally invalid, and that
it would be beneficial to repaint the output immediately. This will only
trigger when the display had previously been disabled or the previous
state is unknown, e.g. at startup, or coming back from DPMS off.

11ae2a3036 compositor-drm: pageflip timeout implementation
Weston will not repaint until previous update has been acked by a
pageflip event coming from the drm driver. However, some buggy drivers
won’t return those events or will stop sending them at some point and
Weston output repaints will completely freeze. To ease developers’ task
in testing their drivers, this patch makes compositor-drm use a timer
to detect cases where those pageflip events stop coming.

This timeout implementation is software only and includes basic
features usually found in a watchdog. We simply exit Weston gracefully
with a log message and an exit code when the timout is reached.

The timeout value can be set via weston.ini by adding a
pageflip-timeout=<MILLISECONDS> entry under [core]
section. Setting it to 0 disables the timeout feature.

v2:
- Made sure we would get both the pageflip and the vblank events before
  stopping the timer.
- Reordered the error and success cases in
  drm_output_pageflip_timer_create() to be more in line with the rest
  of the code.

v3:
- Reordered (de)arming of the timer with the code around it to avoid it
  being rearmed before the current dearming.
- Return the proper value for the dispatcher in the pageflip_timeout
  callback.
- Also display the output name in case the timer fires.

v4:
- Reordered a forgotten timer rearming after its drmModePageFlip().

Preserving the existing routing means that startup will be faster: on a

then re-enabling them with a new configuration, which may involve
retraining links etc.

Furthermore, the existing routing may be set for a reason; each
CRTC/encoder is not necessarily as capable as the other, so the routing
may be configured to stay within such device limits.

Try where possible to respect the routing we pick up, rather than
blithely configuring our own.

weston can be started with --connector option to be initialized
with a particular output. But in the update_outputs this option
is not considered and output is created for all the available
connectors. This patch fixes this issue by considering
the option for connectors in the update_outputs.

c8890125ad compositor-drm: don't put y-inverted / interlaced / bottom-first dmabufs on overlays
This patch checks the attribute flags on incoming dmabufs and refuses to
put them overlays if they have any of the flags set (currently:
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_Y_INVERT,
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_INTERLACED and
ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_BOTTOM_FIRST), instead defaulting to
the gl-renderer which can handle some of the flags.

This check should be superceded by buffer transforms, when they become
available.

fb4869d628 compositor: Assign new views to the primary plane
When we create a new view, assign it to the primary plane from the
beginning.

Currently, every view across the compositor will be assigned to a plane
during every repaint cycle of every output: the DRM renderer's
assign_planes hook will either move a view to a drm_plane, or to the
primary plane if a suitable drm_plane could not be found for the output
it is on. There are no other assign_planes implementation, and the
fallback when none is provided, is to assign every view to the primary
plane.

DRM's behaviour is undesirable in multi-output situations, since it
means that views which were on a plane on one output will be demoted to
the primary plane; doing this causes damage, which will cause a spurious
repaint for the output. This spurious repaint will have no effect on the
other output, but it will do the same demotion of views to the primary
plane, which will again provoke a repaint on the other output.

With a simple fix for this behaviour (i.e. not moving views which are
only visible on other outputs), the following behaviour is observed:
  - outputs A and B are present
  - views A and B are created for those outputs respectively, with SHM
    buffers attached; view->plane == NULL for both
  - current buffer content for views A and B are uploaded to the
    renderer
  - output A runs its repaint cycle, and sets keep_buffer to false on
    surface B's output, as it can never be promoted to a plane; it does
    not move view B to another plane
  - output B runs its repaint cycle, and moves view B to the primary
    plane
  - weston_view_assign_to_plane has work to do (as the plane is changing
    from NULL to the primary plane), calls weston_surface_damage and
    calls weston_surface_damage
  - weston_surface_damage re-uploads buffer content, possibly from
    nowhere at all; e508ce6a notes that this behaviour is broken

Assigning views to the primary plane when created makes it possible to
fix the DRM assign_planes implementation: assign_planes will always set
keep_buffer to true if there is any chance the buffer can ever be
promoted to a plane, regardless of view configruation. If the buffer
cannot be promoted to a plane, it must by definition never migrate from
the primary plane. This means that there is no opportunity to hit the
same issue, where the buffer content has already been discarded, but
weston_view_assign_to_plane is not a no-op.

893b936f9a Remove DPMS-on when going offscreen
Forcing DPMS on when we lose our session may force an expensive modeset
operation, which is pointless if the next consumer (another compositor,
or the console) is going to do a modeset. These should force DPMS on
regardless.

This actively causes problems for the DRM backend, in that it may
actually require a repaint to set coherent state for DPMS off -> DPMS on
transitions, which is very much not what we want when going offscreen.

As DRM is the only backend which actually implements DPMS, just remove
this call.

This always changes the state to ACTIVE when we enter the session,

session, it's probably in order to interact with it.

75b7197f4e Add configuration option for no input device.
As it has been discussed in the past [1], running Weston
without any input device at launch might be beneficial for
some use cases.

Certainly, it's best for the vast majority of users (and
the project) to require an input device to be present, as
to avoid frustration and hassle, but for those brave souls
that so prefer, this patch lets them run without any input
device at all.

This introduces a simple configuration in weston.ini:
  [core]
  require-input=true

True is the default, so no behavioral change is introduced.

c3d2f960d2 weston: Port X11 backend to new output handling API
This is a complete port of the X11 backend that
uses recently added output handling API for output
configuration.

- Output can be configured at runtime by passing the
  necessary configuration parameters, which can be
  filled in manually, obtained from the configuration
  file or obtained from the command line using
  previously added functionality. It is required that
  the scale and transform values are set using the
  previously added functionality.

- Output can be created at runtime using the output
  API. The output creation only creates a pending
  output, which needs to be configured the same way as
  mentioned above.

Same as before, a single output is created at runtime
using the default configuration or a configuration
parsed from the command line. The output-count
functionality is also preserved, which means more than
one output can be created initially, and more outputs can
be added at runtime using the output API.

v2:

 - Fix wet_configure_windowed_output_from_config() usage.
 - Call x11_output_disable() explicitly from
   x11_output_destroy().

v3:

 - Remove unneeded free().
 - Disallow calling x11_output_configure more than once.
 - Remove unneeded checks for output->name == NULL as that
   has been disallowed.
 - Use weston_compositor_add_pending_output().
 - Bump weston_x11_backend_config version to 2.

174448a91b weston: Port Wayland backend to new output handling API

- Output can be created at runtime using the output
  API. The output creation only creates a pending
  output, which needs to be configured the same way as
  mentioned above.

However, the backend can behave both as windowed backend
and as a backend that issues "hotplug" events, when
running under fullscreen shell or with --sprawl command
line option. The first case was covered by reusing
previously added functionality. The second case required
another API to be introduced and implemented into both
the backend and compositor for handling output setup.

After everything has been set, output needs to be
enabled manually using weston_output_enable().

v2:

 - Fix wet_configure_windowed_output_from_config() usage.
 - Call wayland_output_disable() explicitly from
   wayland_output_destroy().

v3:

 - Get rid of weston_wayland_output_api and rework output
   creation and configuration in case wayland backend is

 - Remove unneeded free().
 - Disallow calling wayland_output_configure more than once.
 - Remove unneeded checks for output->name == NULL as that
   has been disallowed.
 - Use weston_compositor_add_pending_output().

v4:

 - Drop unused fields from weston_wayland_backend_config
   and bump WESTON_WAYLAND_BACKEND_CONFIG_VERSION to 2.
 - Move output creation to backend itself when
   --fullscreen is used.
 - Prevent possible duplicated output names by assigning
   a different name to outputs created without any
   configuration specified.

4690c56abc libweston: Add initial output API for windowed outputs configuration
This adds new plugin-specific API for configuring outputs
on "windowed" backends, such as X11, wayland/non-fullscreen
and even headless (although, it doesn't have any windows,
its configuration is very similar). It can be used from
compositors to configure pending outputs and should be used
with previously added weston_output_set_{scale,transform}
to properly configure an output before enabling it.

It also supports creating additional outputs on the mentioned
backends.

v2:

 - Rename output_configure() to output_set_size().
 - Document return values.

a01ab6d525 libweston: Add more functionality for handling weston_output objects
This patch implements additional functionality that will be used
for configuring, enabling and disabling weston's outputs. Its
indended use is by the compositors or user programs that want to
be able to configure, enable or disable an output at any time. An
output can only be configured while it's disabled.

The compositor and backend specific functionality is required
for these functions to be useful, and those will come later in
this series.

All the new functions have been documented, so I'll avoid
describing them here.

v2:

 - Minor documentation improvements.
 - Rename output-initialized to output->enabled.
 - Split weston_output_disable() further into
   weston_compositor_remove_output().
 - Rename weston_output_deinit() to weston_output_enable_undo().

 - Make weston_output_disable() call two functions mentioned
   above instead of calling weston_output_disable() directly.
   This means that backend needs to take care of doing backend
   specific disable in backend specific destroy function.

v3:

 - Require output->name to be set before calling
   weston_output_init_pending().
 - Require output->destroying to be set before
   calling weston_compositor_remove_output().
 - Split weston_output_init_pending() into
   weston_compositor_add_pending_output() so pending outputs
   can be announced separately.
 - Require output->disable() to be set in order for
   weston_output_disable() to be usable.
 - Fix output removing regression that happened when
   weston_output_disable() was split.
 - Minor documentation fix.

v4:

 - Bump libweston version to 2 as this patch breaks the ABI.

f8300c87d5 compositor: Add internal support to track idle inhibition requests
Adds a helper routine weston_output_inhibited_outputs() which returns a
mask of outputs that should inhibit screen idling.

Use this routine to check for inhibiting outputs for handling of idle
behaviors in core:  In sleep mode, only halt repainting outputs that
don't have valid inhibits.  Don't send these monitors DPMS off commands
either, if the system would otherwise be powering them down.

gl-renderer, simple-dmabuf-v4l: fix dmabuf y-invert
Invert the Y_INVERT flag for the EGL import fo dmabufs. This fixes
weston-simple-dmabuf-intel to show the same image on both GL-composited
and with direct scanout on a hardware plane. Before, the image would
y-flip when switching between these two cases. Now the orientation also
matches the color values written in simple-dmabuf-intel.c.

The GL-renderer uses the OpenGL convention of texture coordinates, where
the origin is at the bottom-left of an image. This can be observed in
texture_region() where the texcoords are inverted if y_invert is false,
since the surface coordinates have origin at top-left.  Both wl_shm and
dmabuf buffers have origin at the top-left.

When wl_shm buffer is imported with glTexImage2D, it gets inverted
because glTexImage2D is defined to read in the bottom row first. The shm
data is top row first. This incidentally also means, that buffer pixel
0,0 ends up at texture coordinates 0,0. This is now inverted compared to
the GL coordinate convention, and therefore gl_renderer_attach_shm()
sets y_inverted to true. This causes texture_region() to NOT invert the
texcoords. Wayland surface coordinates have origin at top-left, hence
the double-inversion.

Dmabuf buffers also have the origin at top-left. However, they are
imported via EGL to GL, where they should get the GL oriented
coordinates but they do not. It is as if pixel 0,0 ends up at texcoords
0,0 - the same thing as with wl_shm buffers. Therefore we need to invert
the invert flag.

Too bad EGL_EXT_image_dma_buf_import does not seem to specify the image
orientation. The GL spec implied result seems to conflict with the
reality in Mesa 11.2.2.

I asked about this in the Mesa developer mailing list. The question with
no answers:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120249.html
and the thread I hijacked to get some answers:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120733.html
which culminated to the conclusion:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120955.html
that supports this patch.

simple-dmabuf-v4l is equally fixed to not add Y_INVERT. There is no
rational reason to have it, and removing is necessary together with the
GL-renderer change to keep the image the right way up. This has been
tested with VIVID.

Introduce libweston-desktop
libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.

The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.

The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.

The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.

All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).

All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.

e54038497d compositor: Mark all views as dirty when a new output is assigned
When all outputs are gone and views were created before they
were gone, such views would have no output object assigned and
nothing would assign it later. This makes sure all views are
set as dirty, so they can get an output assigned when an
output gets plugged in, if they didn't have any output assigned.

This change also works when a new output is added even if there already
are outputs in use. A view may be partly off-screen. If the new output
appears at a position where it overlaps an existing view, that view
should get updated.

It is enough to process only the main view_list, because views not on
that list are not shown for the moment and so do not need an immediate
update. Instead, they will get updated later as needed because making an
off-list view to go on-list inherently requires calling
weston_view_geometry_dirty().

30d61d89c1 Implement the relative pointer protocol
A wp_relative_pointer object is an extension to the wl_pointer interface
only used for emitting relative pointer events. It will only emit events
when the parent pointer has focus.

To get a relative pointer object, use the get_relative_pointer request
of the global wp_relative_pointer_manager object.

The relative pointer protocol is currently an unstable protocol, so
unstable protocol naming conventions has been applied.

Activate a view even though it effectively may already be active.
Without this, in later patches, it won't be possibe to track what view
was activated by clicking last, as a view which surface already had
keyboard focus, won't be activated.

To keep avoiding sending xdg_surface.configure events, only change the
keyboard focus if the focus actually changed.

375759e636 Require base-10 for strtol() calls
The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.

This change is an expansion of f6051cbab8
to cover the remaining strtol() calls in Weston, where the routine is
being used to read fds and pids - which are always expressed in base-10.
It also changes the calls in config-parser, used by
weston_config_section_get_int(), which in turn is being used to read
scales, sizes, times, rates, and delays; these are all expressed in
base-10 numbers only.

The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line.  Also, by making the code
consistent with other usages of strtol, it may make it possible to
factor out the common code in the future.

f8486c33b4 compositor: Untangle surface/view is_mapped from output assignments
Currently, weston assumes a surface/view is mapped if
it has an output assigned. In a zero outputs scenario,
this isn't really desirable.

This patch introduces a new flag to weston_surface and
weston_view, which has to be set manually to indicate
that a surface/view is mapped.

v2:

- Remove usage of new flags from
  weston_{view,surface}_is_mapped at this point. They
  will be added after all the implicit mappings have
  been introduced
- Unmap a surface before unmapping a view so the input
  foci is cleaned up properly
- Remove implicit view mapping from view_list_add
- Cosmetic fixes

v3:

- Rebased to apply on git master

9c764df043 xwayland: make the plugin usable by libweston compositors
This patch follows a similar approach taken to detach the backends from
weston. But instead of passing a configuration struct when loading the
plugin, we use the plugin API registry to register an API, and to get it
in the compositor side.  This API allows to spawn the Xwayland process
in the compositor side, and to deal with signal handling.  A new
function is added in compositor.c to load and init the xwayland.so
plugin.

Also make sure to re-arm the SIGUSR1 when the X server quits.

28d240f281 gl-renderer: Always setup gl-renderer
Currently, the gl-renderer setup is being done on per-output
basis. This isn't desirable when trying to make weston run
with zero outputs.

When there are no outputs present, there is no surface available
to attach an EGLContext to with eglMakeCurrent, which makes
any EGL command fail.

The problem is solved by using EGL_KHR_surfaceless_context to
bind an EGLContext to EGL_NO_SURFACE, or if that is
unavailable, creating a dummy PbufferSurface and binding an
EGLContext to it, so EGL gets set up properly.

v2:

- Move PbufferSurface creation into its own function
- Introduce a new EGLConfig with EGL_PBUFFER_BIT set
  and use it to create a PbufferSurface
- Make PbufferSurface attributes definition static
- Check for return of gl_renderer_setup and terminate
  in case it fails
- Remove redundant gl_renderer_setup call from
  gl_renderer_output_create
- Only destroy the dummy surface if it is valid

This patch causes a warning from Mesa when using the i965 driver:
