e262d4fde6 kwin: Enable loose binding with the Intel driver 2012-10-30 18:23:06 +01:00

26a9a35b2f Increase runtime requirement to Mesa 8.0
Adjustment to reality. KWin has had a dependency on Mesa 8.0 for quite
some time given that it is what basically all distributions ship.

It is better to clearly state what is required. For KWin Mesa 8.0 is a
more reliable dependency as all DRI drivers which do not support DRI2
have been removed.

Packagers have been informed about this intended change some weeks ago.

57c27c2e0b GLPlatform can recommend the compositor to use
During detecting the OpenGL capabilities also a recommended compositor
can be set. This recommendation is honoured by the OpenGL based
compositors. That is the SceneOpenGL2 requires a recommendation for at
least OpenGL2 and the SceneOpenGL1 requires at least a recommendation for
OpenGL1. If the driver recommends XRender compositing the SceneOpenGL
performs the existing fallback to XRender.

With this recommendation the hacks in the Scene are removed, e.g. it is
no longer checked whether the driver is software emulation as that is
provided through the recommendation.

To overrule the recommendation the environment variable KWIN_COMPOSE is
extended by the values O1 and O2 to enforce either OpenGL 1 or OpenGL 2.
This overwrites all other checks. As a side-effect this allows now to run
KWin on the llvmpipe:
LIBGL_ALWAYS_SOFTWARE=1 KWIN_COMPOSE=O2 kwin --replace &

But not that I would recommend to use it :-)

e84118d9f8 Add detection support for VMware driver (SVGA3D) to GLPlatform
VMware uses a Gallium driver which means that OpenGL based compositing
works out of the box without any adjustments to GLPlatform.

Just adding recognizing code for the SVGA3D driver.

388edab9e5 Add support for OpenGL in VirtualBox
OpenGL is properly working if there is a direct rendering context.
If LIBGL_ALWAYS_INDIRECT is set VirtualBox falls back to Mesa's software
rasterizer. So in order to get OpenGL the driver is now whitelisted in
the opengltest.

GLPlatform is extended to recognize the VirtualBox driver and has new
methods to report whether it is a virtual machine and VirtualBox. The
detection is rather limited as we don't get access to the underlying
hardware, so we do not know whether the features are really supported.
We need to trust the driver here in announcing the right extensions.

The driver does not provide glxQueryDrawable although it is part of
GLX 1.3. A hack is added in the glxbackend to set the function pointer to
NULL. This can unfortunately not be done in glxResolveFunctions() as
QueryDrawable seems not to be provided by an extension (at least not
listed in the OpenGL registry) and getProcAddress resolves a function but
it only prints an OpenGL Warning to stderr.

As a note: the driver reports that it is using XSHM for
GLX_EXT_texture_from_pixmap.

a401558a43 Provide OpenGL over Egl
The Egl backend is decoupled from the OpenGL ES build option which makes
it possible to use it as a replacement for glx.

To make this possible a new build flag is added when egl is available at
compile time and any egl specific code is now ifdefed with this flag
instead of the gles flag. In addition at runtime a windowing system enum
value is passed to the various detect methods to have egl/glx specific
detection for e.g. function pointer resolving.

By default egl is used if compiled with OpenGL ES, otherwise glx is used.
But in the non-gles case the windowing system can be selected through the
new environment variable KWIN_OPENGL_INTERFACE. Setting this variable to
"egl" the EglOnXBackend is used.

a210b75009 Initialize variables in GLPlatform
m_textureNPOT and m_limitedNPOT have not been initialized in the ctor resulting in
m_limitedNPOT being incorrectly being true sometimes for Intel drivers. For other
drivers the value had been set.

e8a038d66f More getters for GlPlatform
A few more getters for parsed information are added to GlPlatform.
This includes the driver information retrieved through glGetString
and information like direct rendering and loose binding.

Additionally the methods to convert version, driver and chipClass
to string are added to the public interface.

These changes allow parts outside GlPlatform to get the same debug
information about the GL system.

9e2b6edf02 kwin: bugfix nouveau GLES + loose texture bindings in kwin_gles
There seems to be a problem with nouveau GLES if you want to create an
EGLImageKHR more than once in a frame for the same pixmap. This patch
circumvents the problem in the way that it implements tfp the same way
as the mesa example in
mesa/demos/src/egl/opengles1/texture_from_pixmap.c does it. A nice
side effect of this is that it also avoids the overhead of recreating
the texture for every damaged window.

9f78276dc7 Detect Driver "Software Rasterizer"
Fixes a major regression which allowed OpenGL
compositing to be used with software rasterizer, which
either did not work or crashed directly.

Cherry-picked from cf2f572 in branch KDE/4.7.

1dd614ee4b Improved detection of OpenGL software emulation
Adding a new method to retrieve whether the OpenGL implementation
uses any kind of software emulation and no software emulation can
provide GLSL support, even if it claims so.

Thanks to Maurel for testing again and again proposed patches.

57d11c134a Move kwineffects library into own directory
Second part of cleaning up the lib directory: the effects library
now lives in libkwineffects/ directory.

For existing effects nothing changes as the install path is unchanged.
The change obsoletes the lib/ directory.

As glplatform.h has not yet been exported I dared to export it and
adjust the places where it is used.
