There were 3 problems with previous version:
- it didn't take into account libgbm cflags (fatal error: gbm.h: No such file or directory)
- it was vulnerable to gbm.h include bugs (gbm.h:259:50: error: unknown type name 'size_t')
- it was checked even when libgbm was not detected
Fix it.

Defining *_la_CPPFLAGS var in "if...endif" block breaks generation
of Makefile.in - automake assumes it's defined unconditionally and
uses it for building objects.
configure.ac clears all variables if each dependency is disabled so we can
include it unconditionally.

Mesa 8.1-devel/9.0-devel stopped exposing EGL_KHR_surfaceless_opengl because
it never actually existed and started exposing EGL_KHR_surfaceless_context.
Check that in addition to EGL_KHR_surfaceless_opengl.

Instead of redrawing on change, we now use a framerate-timer which
redraws the screen. This timer stays active for 1s after the last redraw
so we do not enable/disable the timer while the console is under heavy
work-load. This still needs to be benchmarked but it seems to work nicely.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
If there is plenty data available, we should read all of it before
returning. Otherwise, we might spend too much time letting the other
subsystems perform actions. This can have the effect, that we render after
each read() on the pty if a redraw takes more time than a single frame.
This is definitely not what we want.
To avoid staying here too long we use a hard-coded maximum. Otherwise, if
the vte layer takes longer than the pty-end writes data to us, we might
stay here forever. This is very unlikely as the VTE layer as no immediate
side-effects that make long computations, but we use it to be on the safe
side.

OpenGLESv2 doesn't support specifying stride values for textures without
this extension. So allocate a temporary storage when uploading values
which have a default-stride.

Upstream mesa renamed gbm_bo_get_pitch() to gbm_bo_get_stride(). As gbm
has not seen an official release, they actually don't care but several
users complained about this. Therefore, we simply add a build-time check
for this. However, this may break when mesa is updated without recompiling
kmscon but that is less intrusive.

This is a weird fix. One would think that this is automatically reset when
calling close() on the fd but, suprise, it's not. So lets reset this
manually, otherwise when we close the VT but our application is still
active, the user will never be able to leave the VT again.
Again a hilarious example why the VT API sucks. Really... Get rid of it.

This actually incorporates the fakevt tool into kmscon. That is, if the
user presses ctrl+mod4+F12, we activate or deactivate the fake VT.
This is for debugging only and needs to be made more configurable. Use it
on your own risk.

If a single rendering-round prints more than 3 warnings for

Similar to the UI subsystem, we also need to be aware of our current state
inside of the terminal subsystem. We can now avoid rendering graphics when
not awake. This suppresses odd warnings that occured when keeping an
application active and printing in the terminal while the terminal was in
background.

We must wake up the UI system _after_ wakeing up everything else,
otherwise, they might assume everything else is already up.

We need to forward all sleep/awake states to the lower subsystems to avoid
overdoing stuff like rendering an user-input. That is, while being asleep
we shouldn't render and/or do any other user-interaction.
This patch simply adds this logic to the UI subsystem, which, however,
does not to anything useful, yet.

We currently have a very subtle bug when modifiers are pressed while
leaving a terminal but released while entering. The internal state will
not be updated and as xkbcommon does not fix this up, we need to recreate

These helpers allow moving around in the scrollback-buffer. Scrolling

The fakevt helper binary can be used on VT-less systems or seats to make
kmscon activate the fake VT and deactivate it. This way, you can control
when kmscon acquires video devices and when it releases them.
This is a global setting that affects all seats where kmscon is running
except seat0 if it uses real VTs.
This should only be used for debugging. This is really no intended for use
in production.

This adds a very limited non-multi-seat-capable fake-VT logic. If you use

On SIGUSR1 we activate fake VTs and on SIGUSR2 we deactivate them. The

If using real linux VTs, we must ignore all signals that are not sent from
the kernel. Otherwise, we might get problems if we reuse SIGUSR for other

Note that we already check that we are the active VT before handling
SIGUSR. However, this hardens this check to be more sure that this is
really the signal we want.
