880b485d76 libweston: Decouple weston_debug_compositor from weston_compositor
This patch allows initialization of weston-debug/log framework much earlier
than weston_compositor, which in turn will provide the option start
logging before weston_compositor has been created.

3957863667 log: remove "%m" from format strings by using strerror(errno)
The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.

In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.

Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).
While there, fix some minor indentation issue.

3d5d9476e3 Rename compositor.h to libweston/libweston.h
The main idea is to make libweston users use the form

 #include <libweston/libweston.h>

instead of the plain

 #include <compositor.h>

which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.

The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

a6acfa8346 compositor: Fix invalid view numbering in scene-graph
With the addition of patch 433f4e77b7 we display the same view id (0)

Displaying sub-surfaces based views is also problematic. The caller need
to modify the view number as well, so we instead we pass the address as
to allow that to happen. Otherwise we end up repeating the same number
for views without sub-subrfaces once those have been printed.

gbm_surface_create will not be called if HAVE_GBM_MODIFIERS is enabled but no
modifiers are supported by the plane. This could happen if _init_egl is called
after drm_ouptut_fini_egl drom drm_output_switch_mode.

Add an assert to guarantee the requirement and clears the gbm_surface pointer

676296749a libweston: Support zwp_surface_synchronization_v1.get_release
Implement the get_release request of the zwp_surface_synchronization_v1
interface.

This commit implements the zwp_buffer_release_v1 interface. It supports
the zwp_buffer_release_v1.fenced_release event for surfaces rendered by
the GL renderer, and the zwp_buffer_release_v1.immediate_release event
for other cases.

Note that the immediate_release event is safe to be used for surface
buffers used as planes in the DRM backend, since the backend releases
them only after the next page flip that doesn't use the buffers has
finished.

Changes in v7:
  - Remove "partial" from commit title and description.
  - Fix inverted check when clearing used_in_output_repaint flag.

Changes in v5:
  - Use the new, generic explicit sync server error reporting function.
  - Introduce and use weston_buffer_release_move.
  - Introduce internally and use weston_buffer_release_destroy.

Changes in v4:
  - Support the zwp_buffer_release_v1.fenced_release event.
  - Support release fences in the GL renderer.
  - Assert that pending state buffer_release is always NULL after a
    commit.
  - Simplify weston_buffer_release_reference.
  - Move removal of destroy listener before resource destruction to
    avoid concerns about use-after-free in
    weston_buffer_release_reference
  - Rename weston_buffer_release_reference.busy_count to ref_count.
  - Add documentation for weston_buffer_release and ..._reference.

Changes in v3:
  - Raise NO_BUFFER for get_release if no buffer has been committed,
    don't raise UNSUPPORTED_BUFFER for non-dmabuf buffers,
    so get_release works for all valid buffers.
  - Destroy the buffer_release object after sending an event.
  - Track lifetime of buffer_release objects per commit, independently
    of any buffers.
  - Use updated protocol interface names.
  - Use correct format specifier for resource ids.

Changes in v2:
  - Raise UNSUPPORTED_BUFFER at commit if client has requested a
    buffer_release, but the committed buffer is not a valid linux_dmabuf.
  - Remove tests that are not viable anymore due to our inability to
    create dmabuf buffers and fences in a unit-test environment.

acff29b3b3 libweston: Support zwp_surface_synchronization_v1.set_acquire_fence
Implement the set_acquire_fence request of the
zwp_surface_synchronization_v1 interface.

The implementation uses the acquire fence in two ways:

1. If the associated buffer is used as GL render source, an
   EGLSyncKHR is created from the fence and used to synchronize
   access.
2. If the associated buffer is used as a plane framebuffer,
   the acquire fence is treated as an in-fence for the atomic
   commit operation. If in-fences are not supported and the buffer
   has an acquire fence, we don't consider it for plane placement.

If the used compositor/renderer doesn't support explicit
synchronization, we don't advertise the protocol at all. Currently only
the DRM and X11 backends when using the GL renderer advertise the
protocol for production use.

Issues for discussion
---------------------

a. Currently, a server-side wait of EGLSyncKHR is performed before
   using the EGLImage/texture during rendering. Unfortunately, it's not clear
   from the specs whether this is generally safe to do, or we need to
   sync before glEGLImageTargetTexture2DOES. The exception is
   TEXTURE_EXTERNAL_OES where the spec mentions it's enough to sync
   and then glBindTexture for any changes to take effect.

Changes in v5:
  - Meson support.
  - Make explicit sync server error reporting more generic, supporting
    all explicit sync related interfaces not just
    wp_linux_surface_synchronization.
  - Fix typo in warning for missing EGL_KHR_wait_sync extension.
  - Support minor version 2 of the explicit sync protocol (i.e., support
    fences for opaque EGL buffers).

Changes in v4:
  - Introduce and use fd_clear and and fd_move helpers.
  - Don't check for a valid buffer when updating surface acquire fence fd
    from state.
  - Assert that pending state acquire fence fd is always clear
    after a commit.
  - Clarify that WESTON_CAP_EXPLICIT_SYNC applies to just the
    renderer.
  - Check for EGL_KHR_wait_sync before using eglWaitSyncKHR.
  - Dup the acquire fence before passing to EGL.

Changes in v3:
  - Keep acquire_fence_fd in surface instead of buffer.
  - Clarify that WESTON_CAP_EXPLICIT_SYNC applies to both backend and
    renderer.
  - Move comment about non-ownership of in_fence_fd to struct
    drm_plane_state definition.
  - Assert that we don't try to use planes with in-fences when using the
    legacy KMS API.
  - Remove unnecessary info from wayland error messages.
  - Handle acquire fence for subsurface commits.
  - Guard against self-update in fd_update.
  - Disconnect the client if acquire fence EGLSyncKHR creation or wait
    fails.
  - Use updated protocol interface names.
  - User correct format specifier for resource ids.
  - Advertise protocol for X11 backend with GL renderer.

Changes in v2:
  - Remove sync file wait fallbacks.
  - Raise UNSUPPORTED_BUFFER error at commit if we have an acquire
    fence, but the committed buffer is not a valid linux_dmabuf.
  - Don't put buffers with in-fences on planes that don't support
    in-fences.
  - Don't advertise explicit sync protocol if backend does not
    support explicit sync.

c0e2f9261f libweston: Introduce an internal linux sync file API
Introduce an internal API for dealing with linux sync files,
and use it in the codebase to replace ad-hoc sync file management.

The linux_sync_file_is_valid function is not currently used, but will be
utilized in upcoming commits to implement the
zwp_linux_explicit_synchronization_unstable_v1 protocol.

Changes in v5:
  - Meson support.

Changes in v3:
  - Use parameter name in function documentation.
  - Move kernel UAPI to separate header file.

Changes in v2:
  - Add function documentation
  - Remove linux_sync_file_wait()

27d7c395c7 libweston: Introduce zwp_linux_explicit_synchronization_v1
Introduce support for the zwp_linux_explicit_synchronization_unstable_v1
protocol with an implementation of the zwp_linux_explicit_synchronization_v1
interface.

Explicit synchronization provides a more versatile notification
mechanism for buffer readiness and availability, and can be used to
improve efficiency by integrating with related functionality in display
and graphics APIs.

In addition, the per-commit nature of the release events provided by
this protocol potentially offers a solution to a deficiency of the
wl_buffer.release event (see
https://gitlab.freedesktop.org/wayland/wayland/issues/46).

Support for this protocol depends on the capabilities of the backend, so
we don't register it by default but provide a function which each
backend will need to call. In this commit only the headless backend when
using the noop renderer supports this to enable testing.

Note that the zwp_surface_synchronization_v1 interface, which contains
the core functionality of the protocol, is not implemented in this
commit. Support for it will be added in future commits.

Changes in v7:
  - Added some information in the commit message about the benefits of
    the explicit sync protocol.

Changes in v6:
  - Fall back to advertising minor version 1 of the explicit sync protocol,
    although we support minor version 2 features, until the new
    wayland-protocols version is released.

Changes in v5:
  - Meson support.
  - Advertise minor version 2 of the explicit sync protocol.

Changes in v4:
  - Enable explicit sync support in the headless backend for all
    renderers.

Changes in v3:
  - Use wl_resource_get_version() instead of hardcoding version 1.
  - Use updated protocol interface names.
  - Use correct format specifier for resource id.
  - Change test name to 'linux-explicit-synchronization.weston'
    (s/_/-/g).

Changes in v2:
  - Move implementation to separate file so protocol can be registered
    on demand by backends.
  - Register protocol in headless+noop backend for testing purposes.

fa2742b380 libweston: fbdev: Force the Framebuffer devices to be activated.
This attempts to wake up secondary framebuffer devices
(/dev/fb1 and up) as usually these devices start powered off, and
the FBIOPUT_VSCREENINFO ioctl turns it on. This was tested on qemu
with two virtual QXL cards. This is a more precise way to activate
framebuffer devices with the ioctl

99553750db compositor-drm: Don't set linear modifier when not supported
This will cause gbm_surface_create_with_modifiers to fail on drivers
where modifiers are not yet supported (e.g. amdgpu). We need to make
sure we only end up using gbm_surface_create in this case.

This fixes the remoting plugin on these drivers.
