a583492ea2 kms-winsys: don't wait for a flip when page flipping fails
If we get EACCES from drmPageFlip we're not going to get
a flip event and shouldn't wait for one.

This commit changes the EACCES path to silently ignore the
failed flip request and just clean up the fb.

4cb750928e winsys: wayland: destroy eglsurface when destroying associated native window
On Wayland deinit() of an onscreen buffer is going to destroy the
associated native window of an EGLSurface. So we should destroy the
EGLSurface as well otherwise we might end up confusing the GL driver.

We also currently guard against setting a EGL_NO_SURFACE as current
EGLSurface, but this shouldn't be a problem if we have a surfaceless
context. So we allow surface destruction under that condition.

6bd49c3dc8 kms-winsys: don't disable page flipping on EACCES
If the user switches VTs in the middle of a page flip, the
page flip operation may fail with EACCES. page flipping will
work next time the VT becomes active, so we shouldn't disable
page flipping in that case.

78c44ab132 kms-winsys: clean up error handling in _cogl_winsys_renderer_connect
If cogl fails to open the drm device, initialize gbm, or open the
egl display, then it closes the drm fd, uninitializes gbm, closes the
display and then calls _cogl_winsys_renderer_disconnect which does
most of those things again, on the, now deinitialized, members.

This commit removes the explicit failure handling in renderer_connect and
defers cleanup to disconnect.

68d9ba3b65 kms-winsys: try to hobble along if driver doesn't support page flips
Some drivers ( like mgag200 ) don't yet support drmModePageFlip.

This commit forgoes waiting for vblank and flips right away
in those cases. That prevents the hardware from freezing up the screen,
but does mean there will be some visible tearing.

200c4032ac kms-winsys: Defer setting new surfaces until swap buffers
We can't just destroy and replace the EGL and gbm surfaces while
they are still in use i.e. while there is a pending flip. In fact, in
that case, we were calling gbm_surface_destroy() on a surface that
still had the front buffer locked and then, on the flip handler,
gbm_surface_release_buffer() for a buffer that didn't belong to the
new surface.

Instead, we still allocate new surfaces when requested but they only
replace the old ones on the next swap buffers when we're sure that the
previous flip has been handled and buffers properly released.

5ccd2825c7 glx: Precisely wait for the next vblank
Currently the code queries the current msc then tries to approximate the
value of the next msc satisfing the modulus 2 for when to wait. This
introduces some instability as the msc may tick over during the
roundtrip leading to a 32ms wait instead of a 16ms wait. This happens
often enough to cause jerky animations, and affect gnome-shell-perf-tool.

A simpler solution is just use a single roundtrip by using WaitForMsc to
ask the driver to compute the next vblank itself.

52a646abc5 Use the EGL_KHR_surfacless_context extension
The surfaceless context extension can be used to bind a context
without a surface. We can use this to avoid creating a dummy surface
when the CoglContext is first created. Otherwise we have to have the
dummy surface so that we can bind it before the first onscreen is
created.

The main awkward part of this patch is that theoretically according to
the GL and GLES spec if you first bind a context without a surface
then the default state for glDrawBuffers is GL_NONE instead of
GL_BACK. In practice Mesa doesn't seem to do this but we need to be
robust against a GL implementation that does. Therefore we track when
the CoglContext is first used with a CoglOnscreen and force the
glDrawBuffers state to be GL_BACK.

There is a further awkward part in that GLES2 doesn't actually have a
glDrawBuffers state but GLES3 does. GLES3 also defaults to GL_NONE in
this case so if GLES3 is available then we have to be sure to set the
state to GL_BACK. As far as I can tell that actually makes GLES3
incompatible with GLES2 because in theory if the application is not
aware of GLES3 then it should be able to assume the draw buffer is
always GL_BACK.

22378d572b cogl-winsys-egl-kms: Call swap notify handler even when pageflip ioctl fails
This can happen when we dpms off the output or when login1 takes away
drm master status from our drm fd.  In either case, we need to call
the swap notify handler so that the compositor dosn't get stuck waiting
for that notification.  The compositor should stop repainting shortly in
both cases, as it's either going into dpms off mode or vt switching away.

This environment variable predates the reliable platform detection in mesa

match what's passed in.  Aside from being unecessary and problematic
it also leaks into the GNOME session, preventing clients from

804082abd3 Expose EGL context/display and GLX context
To help facilitate integration with third party frameworks this exposes
the EGL context and display to applications as well as the GLX context.
(Note that the GLX display is already available via
cogl_xlib_renderer_get_display())

This adds a new top-level <cogl/cogl-glx.h> header that needs to be
included explicitly to access the glx specific api.

Anyone using these apis will be responsible for checking that Cogl
is indeed using EGL or GLX by calling cogl_renderer_get_winsys_id()

This will enable GStreamer, for example, to be able to create a GL
context that shares resources with Cogl's context.
