It was added to skip checking EGLDisplay, EGLSurface, and etc. It is
never defined and the spec does not allow the checks to be skipped.
Remove it for good.
The macros give warnings when compiled with -pedantic. This commit is
based on a patch by Brian Paul, with minor changes to add do {} while(0)
and rename the check macros.
This gives a simple access control to the display. It is potentially
slow, but a finer grained mutex can always be used in the future. The
benefit of this simple approach is that drivers need not to worry about
thread-safety.
egl: eglGetError should return the status of the last call.
Use macros to record the status of the function call before returning.
This is the only way that eglGetError can return the status of the most
recent function call.
Add _EGL_CHECK_* which will replace _EGL_DECLARE_* for error checking.
Move _eglCheck* earlier in the file so that the macros and the functions
are grouped together.
egl_xdri steals code from src/glx/x11/. This makes it broken from time
to time when there is a bigger change to the GLX code. As egl_dri2 has
been merged, which also functions as a DRI2 driver loader, remove
egl_xdri for good.
Both a link and a binding creates a reference to the resource. Drivers
should not destroy the resource when there is a reference. The
difference is better described in doc/egl.html.
There are standard typecast functions that are common to most drivers.
They are used to typecast, for example, an _EGLSurface to a
driver-defined type.
This commits define _EGL_DRIVER_STANDARD_TYPECASTS and
_EGL_DRIVER_TYPECAST that should hopefully save some typings for driver
writers.
Rename _eglPreloadFile to _eglLoaderFile, and _eglPreloadFile to
_eglLoaderFile. There are several _eglPreload* functions. The
callbacks do not belong to them and it should be better to give them a
different prefix.
EGL_DRIVERS_PATH gives a list of colon-separated directories. The given
directories will be searched when preloading drivers.
This is based on Mike Stroyan's patch, which honors the variable in
_eglPreloadDisplayDrivers. It is extended to honor the variable also in
_eglPreloadUserDriver and _eglPreloadDefaultDriver in this version.
Add missing attributes and use correct types in _EGLSurface. Remove
ifdef tests that serve no purpose. Update _eglQuerySurface and
_eglSurfaceAttrib for missing queries and checks.
egl: Add support for more EGLImage extensions to EGL core.
Add support EGL_KHR_vg_parent_image and EGL_KHR_gl_*. This is as simple
as adding some flags that can be enabled. Individual drivers need to
implement the extensions before enbaling the flags.
