Derek Foreman 8743047112 compositor-drm: fix cursor size test in drm_assign_planes
In commit 70d337dfd we changed one cursor size test from a hard coded 64,64
to the actual device provided width, height.

The test in drm_assign_planes remained fixed at 64, 64.

The simple-shm test ended up being small enough to fit into a cursor plane
by one test, but too large by the test in drm_assign_planes.  We'd assign
to the cursor plane but not keep a reference.

weston-simple-shm would disappear and be replaced with the previous
cursor image.

This partially "fixes" T3361.

The screenshooter encoder wrote the output from either top-to-bottom or
bottom-to-top, depending on the Y-flip setting, but wcap-decode only
decodes from bottom-to-top. Make the encoder always output from
bottom-to-top, to match the decoder, and flip the input (source)

Chokshi, Mitul d669714d71 input: add new client to resource_list instead of focus_resource_list
When new client registers touch listener, it was added to focus resource list.
At this point if another client "without" touch listener is in focus then
subsequent touch events are sent to new client with another client's resources
causing new client to stop rendering.
Now new client is added to resource list by default and it'll be added to focus

Derek Foreman 89dcea9b58 text: Switch to weston_client_start instead of weston_client_launch
We really don't want to deal with sighups and pids.  It's far easier
to just deal with the client destroyed signal to respawn the input method.

Inspiration taken from Pekka's commit 826dc14ec4

This fixes a potential crash on shutdown.  If the input method client
pointer is still set (sighup handler hasn't run) but the client is
already destroyed, a call to text_backend_destroy() will try to destroy
the client a second time resulting in a segfault.

John Sadler ca510d06dc rpi: fix segfault at startup in rpi_flippipe_init() v2
When running with the RPi backend, Weston now segfaults at startup on the
line:

    flippipe->clk_id = output->base.compositor->presentation_clock;

in `rpi_flippipe_init()`.

This is because `output->base.compositor` is NULL. This problem did not
exist on 1.8.0, and it looks like it may have been introduced by 954f183e2f.

This commit ensures that the `compositor` is initialised in `rpi_backend`
and that flippipe init uses the compositor pointer from backend.

Changes in v2:
- fix summary to not break the build
- use output->backend->compositor in rpi_flippipe_init() instead of
  output->base.compositor. The latter is set by weston_output_init()
  which gets called later than rpi_flippipe_init().

Pekka Paalanen 3f32a13acd Revert "compositor-drm: disable hardware cursors"
This reverts commit 6858383d51.

The main reason for the original patch was a regression on the Intel
drivers causing compositor framerate to drop to half during cursor
updates or motion. The Intel problem was fixed in
https://github.com/torvalds/linux/commit/2e7f43c41c042d6fed4d67aceeaae32d8f102e98
The fix is included in Linux 4.1-rc6 and 4.0.5.

The comment in the original patch is still true, but arguably the
possible minor glitches with cursor updates are less bad than not using
cursor planes at all.

Pekka Paalanen 89c49b3060 compositor-drm: rename outputs to follow kernel style
The problem with the old table of names is that it contains duplicates.
It is possible to end up with multiple outputs with the same name. In
that case you cannot write individual configurations for these outputs
in weston.ini, because they are matched by the name.

Change all names to follow the kernel naming scheme set in
drivers/gpu/drm/drm_crtc.c. The snprintf format now follows the kernel
style, too. Use the DRM_MODE_CONNECTOR_* macros rather than implicit
table ordering.

Completely new entries in the table are "Virtual" and "DSI".

There should not be any gaps in the macro values, but if there are, deal
with a NULL entry.

Also change "UNKNOWN" to "UNNAMED" so it's easier to distinguish from
"Unknown" by the kernel.

The buildbots discovered this issue on Ubuntu 14.04, which carries
libgbm 10.1.3-0ubuntu0.4.  The dmabuf changes need gbm 10.2, so it fails
during build like this:

  src/compositor-drm.c: In function ‘drm_output_prepare_overlay_view’:
  src/compositor-drm.c:984:10: error: variable ‘gbm_dmabuf’ has
  initializer but incomplete type
     struct gbm_import_fd_data gbm_dmabuf = {
            ^
  etc.

Proposed fix is to conditionalize the gbm fd import feature in

This fix was suggested by daniels.  I set up a synthetic test
environment to reproduce the issue as found by the buildbots and tweaked
the patch to get it to build both with and without gbm 10.2.

Pekka Paalanen a352580285 gl-renderer: add dmabuf import
Import dmabuf as an EGLImage, and hold on to the EGLImage until we are
signalled a content change. On content change, destroy the EGLImage and
re-import to trigger GPU cache flushes.

We hold on to the EGLImage as long as possible just in case the client
does other imports that might later make re-importing fail.

As dmabuf protocol uses drm_fourcc codes, we need libdrm for
drm_fourcc.h. However, we are not doing any libdrm function calls, so
there is no new need to link to libdrm.

RFCv1 changes:
- fix error if dmabuf exposed unsupported
- always use GL_TEXTURE_EXTERNAL_OES with dmabuf

v2 changes:
- improve support check and error handling
- hold on to the imported EGLImage to avoid the dmabuf becoming
  unimportable in the future
- send internal errors with linux_dmabuf_buffer_send_server_error()

Dawid Gajownik f3c8336320 weston-launch: On error putenv returns a non-zero value
According to POSIX standard "upon successful completion, putenv() shall
return 0; otherwise, it shall return a non-zero value." Unlike in
setenv() we should not be checking only for negative values.

Dawid Gajownik 2f7d33d984 compositor: fix crash when destroying incompletely created output
When the output can't be completely created in the backend (for example
lack of memory), weston_compositor_add_output() is never run. In such
a case output->link is not initialized. Letter, when
weston_output_destroy() is called, application crashes on
wl_list_remove(&output->link).

This problem happens when drm, fbdev, rdp, rpi or wayland backend is
used.

v2: Initialize output->link in weston_output_init() as suggested by
Derek Foreman.
