The Wayland protocol permits a client to request the pointer, keyboard
and touch multiple times from the seat global. This is very useful in a
component like Clutter-GTK where we are combining two libraries that use
Wayland together.
This change migrates the weston input handling code to emit the
events for all the resources for the client by using the newly added
wl_resource_for_each macro to iterate over the resources that are
associated with the focused surface's client.
We maintain a list of focused resources on the pointer and keyboard
which is updated when the focus changes. However since we can have
resources created after the focus has already been set we must add the
resources to the right list and also update any state.
Additionally when setting the pointer focus it will now send the
keyboard modifiers regardless of whether the focused client has a
pointer resource. This is important because otherwise if the client
gets the pointer later than you getting the keyboard then the
modifiers might not be up-to-date.

This patch implements the notification of clients during mode_switch.
As discussed on IRC, clients are notified of mode_switch only when the
"native" mode is changed and activated. That means that if the native
mode is changed and the compositor had activated a temporary mode for
a fullscreen surface, the clients will be notified only when the native
mode is restored.
The scaling factor is treated the same way as modes.
the unmap event will be followed by the deletion of the weston_surface,
so the shell_surface will also be deleted by the shell. Having removed
the surface_destroy_listener, the surface_destroy callback doesn't
get called, so reset the value of shsurf here.
After the fade or zoom effects, alpha could not have been 1.0, preventing
not redrawing behind opaque windows.
This patch add a reset function in weston_surface_animation to reset
some variables the effects affect.

The struct weston_launcher object will now either handle tty and vt switching
details in-process (when running weston directly as root) or talk to
the weston-launch process.
Previously, vaapi_recorder_frame() would wait until the encoded
contents for a frame is written to the output file descriptor. This
delayed the repainting of the next frame, and affected frame rate
when capturing with high resolutions. Instead, wait only if there is
and attempted to encode two frames at the same time.
Increases framerate from 30 to 60 fps when capturing at 1920x1200 on
my SandryBridge system, although there are periodic slowdowns due to
disk writes.
it uses the Android fbdev HAL[1] (through libhybris[2])
and the libhybris implementation of wayland-egl.
Configure flags:
cairo:
--enable-glesv2=yes --enable-egl=yes
weston:
--with-cairo-glesv2 --enable-fbdev-compositor
hybris:
--enable-wayland --enable-arch=x86
--with-android-headers=<android-headers> --enable-alinker=jb
The android headers are extracted from an AOSP tree,
using hybris/utils/extract-headers.sh

Hi Kristian,
Here's a new patch for ref counting weston_xkb_info, as suggested.
So a seat created with a NULL keymap will now point to the global xkb_info.
Typically we can write it immediately without blocking, so save the overhead
of setting up an fd watch and writing the data in a callback. For the
case where the immediate write doesn't write all data, we fallback and
set up the fd watch as usual.
This patch also consolidates setting up the async write a bit.
This makes the drag-and-drop code available to in-weston data sources,
similar to how we can set a selection data source internally. The
wl_data_device.start_drag entry point now calls this function after
validating protocol arguments.
Another silent regression from the wl_resource opaquify effort. This was
causing our pageflip-to-client-buffer and sprites optimizations to
not kick in.
We used to destroy the frame window and reparent the client window to
wm_window. That means that we lose the destroy_notify event when the
client window is destroyed later, since we don't select for
substructure_notify on wm_window.
Instead of destroying and reparenting, just unmap the frame window.
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.
GL_UNSIGNED_INT is only supported when GL_OES_element_index_uint is
available (mesa implements that extension). We don't need 32-bit
indices, so just use GL_UNSIGNED_SHORT.
