Otherwise, when it is called from within a driver, the caller cannot
free the returned data (on Windows).
|
|
Mainly to rename _eglAddConfig to _eglLinkConfig, along with a few clean
ups.
|
|
Replace SET_CONFIG_ATTRIB/GET_CONFIG_ATTRIB by direct dereferences.
|
|
This makes _EGLConfig more accessible and scales better when new
attributes are added.
|
|
The API of the context was not checked against EGL_RENDERABLE_TYPE when there
was no attribute list. Move the check to _eglInitContext, and be verbose about
common mistakes (EGL_RENDERABLE_TYPE not set, EGL_CONTEXT_CLIENT_VERSION not
set, or eglBindAPI not called).
|
|
This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.

This extension allows a color buffer to be used for both rendering and
texturing. EGL allows the use of color buffers of pbuffer drawables
for texturing, this extension extends this to allow the use of color
buffers of pixmaps too.

Passing 0x3030, 0 in the chooser list didn't get caught.

When there is no user driver or any matching display drivers we fall
back to the default driver. This patch lets us have a list of default
drivers instead of just one. The drivers are loaded in turn and we
attempt to initialize the display. If it fails we unload the driver
and move on to the next one.
Compared to the display driver mechanism, this avoids loading a number
of drivers and then only using one. Also, we call Initialize to see
if the driver will work instead of relying on Probe. To know for sure
that a driver will work, Probe really have to do a full Initialize, so
we will just use Initialize directly.

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.
|
|
Just follow gcc's advices here.
|
|
It might be desirable find out which attribute went wrong.
|
|
EGL_SCREEN_BIT_MESA is a valid bit only when EGL_MESA_screen_surface is
supported.
|
|
This changes _eglInitConfig to take the display as its argument.
|
|
Mainly to remove eglcurrent.h and egldisplay.h from eglglobals.h.
|
|
|
|
Update to the current versions found at
http://www.khronos.org/registry/egl/. There is one modification in
khrplatform.h for GCC visibility.
|
|
Update _eglValidateConfig so that it passes the test.

A stupid bug by me made the check void.

Make it similiar to how contexts and surfaces are looked up. It should
be slightly faster, and work better with multiple displays.

This mainly implements the algorithms for configuration selection and
sorting, described in the spec. User errors should also be correctly
detected and reported.

Config keys are almost config attributes. A valid config attribute is a
valid config key, but a valid config key may not be a valid config
attribute.
This commit does not distinguish the differences.

The motivation is so that drivers do not need to look up and check for
bad display, context, and etc. It also becomes unnecessary for drivers
to call the link functions.
This commit makes eglapi.[ch] do the lookup and check. As a result, the
driver API is overhauled, and almost all sources and drivers need
update. The updates are mainly find and replace with human brains.

Casting an unsigned int to or from a pointer directly gives warnings on
x86-64. Add wrappers to silence the warnings.

work correctly with GLES1 and GLES2.
- egl_xdri.c just sets the EGL_OPENGL_ES_BIT as well as the
EGL_OPENGL_BIT in ClientAPIsMask
- eglconfig.c allows the renderable type to include EGL_OPENGL_ES2_BIT
as well as EGL_OPENGL_ES_BIT.
- egl_xlib.c sets the EGL_NATIVE_RENDERABLE attribute to EGL_FALSE for
all softpipe configurations. (Otherwise, an eglChooseConfig() that
looks for particular values of EGL_NATIVE_RENDERABLE will fail.)

This allows subclassing by drivers.

These are the inverse of the _eglLookup*() functions.
Returns the public handle for a private surface/config/display/etc.
Removes glapi.c's direct access of private fields.

Redo _eglInitContext() to do error checking, attribute list parsing, etc.

Seems to be mostly working. Not all of egl API is implemented.
