Previously the option was --enable-demo-clients and the conditional was
ENABLE_DEMO_CLIENTS. They control whether or not we install the demo clients
(ie all other clients than weston-terminal and weston-info). Rename the
option and the conditional to better reflect this.
This adds a test that tries to simulate a simple game loop that would
be like this:
while (1) {
draw_something();
eglSwapBuffers();
}
In this case the test is relying on eglSwapBuffers to throttle to a
sensible frame rate.
The test then verifies that only 2 EGL buffers are used. This is done
via a new request and event in the wayland-test protocol.
Currently this causes 3 buffers to be created because the release
event generated by the swap buffers is not processed by Mesa until it
blocks for the frame complete event in the next swap buffers call, but
that is too late.
This can be fixed in Mesa by issuing a sync request after the swap
buffers and blocking on it before deciding whether to allocate a new
buffer.
The tablet-shell is unmaintained and unused. It is currently
dead-weight and a burden when we make changes to weston. Let's
drop it for now, we can pull it out of git if we find a need for it later.
If posix_fallocate is available, use it instead of ftruncate. Unlike
ftruncate, when posix_fallocate succeeds, it guarantees that you cannot
run out of disk space, when later writing to the mmap()'ed file.
With posix_fallocate, if os_create_anonymous_file() succeeds, the
program cannot get a SIGBUS later from accessing this file via mmap. If
there is insufficient disk space, the function fails and errno is set to
ENOSPC.
This is useful on systems, that limit the available buffer space by
having XDG_RUNTIME_DIR on a small tmpfs.

The default can be set by passing WESTON_SHELL_CLIENT as an argument
to configure, similarly to WESTON_NATIVE_BACKEND.

If libdrm is available, weston-launch and launcer-util.c will support
getting the drm device and setting and dropping drm master, otherwise
we'll only support getting input devices.
This adds a window frame with a close button. Similar to the X11 backend,
The window supports dragging but not resizing.

Instead of connecting to weston-launch from launcher-util, we now try to
connect to logind first. If logind provides session-devices, we use them.
If not, we fall back to the old weston-launch facility.
This adds optional libdbus integration for weston. If libdbus is available
and not disabled via --disable-dbus during weston build, we now provide
basic DBusConnection main-loop integration for weston.
The dbus.c file provides a new helper to integrate any DBusConnection
object into a wl_event_loop object. This avoids any glib/qt/..
dependencies but instead only uses the low-level libdbus library.
Note that we do not provide dummy fallbacks for dbus helpers in case
dbus-support is disabled. The reason for that is that you need dbus/dbus.h
for nearly any operation you want to do via dbus. Therefore, only the most
basic helpers which can be used independently provide a "static inline"
dummy fallback to avoid #ifdef all over the code.
The time spent loading EGL and GLES libraries from disk can be a
considerable hit in some embedded use cases. If Weston is compiled
with EGL support, the binary will depend on those libraries, even if
a software renderer is in use.
This patch splits the GL renderer into a separate loadable module,
and moves the dependency on EGL and GLES to it. The backends still
need the EGL headers for the native types and EGLint. The function
load_module() is renamed to weston_load_module() and exported, so
that it can be used by the backends.
The gl renderer interface is changed so that there is only one symbol
that needs to be dlsym()'d. This symbol contains pointers to all the
functions and data necessary to interact with the renderer. As a side
effect, this change simplifies gl-renderer.h a great deal.
The compositor uses libdrm in launcher-util.c if the drm backend is
built, but there was no explicit requirement in the build. egl brings
libdrm implicity so the build doesn't fail.
This patch adds an explicit dependency between the compositor and
libdrm if the drm backend is built, so that changes to the compositor
modules don't cause build failures.
This patch adds a feature to the DRM backend that uses libva for
encoding the screen contents in H.264. Screen recording can be
activated by pressing mod-shift-space q. A file named capture.h264
will be created in the current directory, which can be muxed into
an MP4 file with gstreamer using
gst-launch filesrc location=capture.h264 ! h264parse ! mp4mux ! \
filesink location=file.mp4
This is limitted to the DRM compositor in order to avoid a copy when
submitting the front buffer to libva. The code in vaapi-recorder.c
takes a dma_buf fd referencing it, does a colorspace conversion using
the video post processing pipeline and then uses that as input to the
encoder.
I'm sending this now so I get comments, but this is not ready for
prime time yet. I have a somewhat consistent GPU hang when using
i915 with SandyBridge. Sometimes a page flip never completes. If you
want to try this anyway and your system get stuck, you might need to
run the following:
# echo 1 > /sys/kernel/debug/dri/0/i915_wedged
After that, alt-sysrq [rv] should work.
Once that's fixed it would also be good to make the parameters used by
the encoder more flexible. For now the QP parameter is hardcoded to 0
and we have only I and P frames (no B frames), which causes the
resulting files to be very large.
Previously the configure script would silently disable the use of
accelerated cairo in the clients if cairo-gl could not be found (or
cairo-glesv2 if that was requested.) Conversely the use of cairo-gl
would be automatically enabled if it was found with no way to disable
that feature
This change adds --with-cairo which takes one of "image", "gl" or
"glesv2" (defaulting to "image"). If "gl" or "glesv2" is specified
cairo-egl is checked for as well as the specified renderer. If the check
fails then the configure process errors out.
This patch adds a configure option which will enable
user to install demo clients if desired. It is disabled
by default.
v2: Remove AC_DEFINE as it is not necesary
AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar
macros to expose the largest extent of functionality supported by the
underlying system. This is required since these macros are often
limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually
on some systems hide declarations which are not part of the X/Open spec.
Since this goes into config.h rather than the command line, ensure all
source is consistently including config.h before anything else,
including system libraries. This doesn't need to be guarded by a
HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org
modular transition.
