This reverts commit 021a68b7e83259faedacea8b3a18e754bed6277a.
|
|
Otherwise, when it is called from within a driver, the caller cannot
free the returned data (on Windows).

Added for completeness. It makes sense to have such mechanism, but I am
not aware of any user of that..
|
|
We have to rely on the pthread key destructor to free the current thread
info when a thread exits.
|
|
So that the directory part of EGL_DRIVER, if exists, is prepended to the
search path. This commit also adds a sanity check to _eglLog.

Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.

This call sequence
eglMakeCurrent(dpy, surf, surf, ctx1);
eglMakeCurrent(dpy, surf, surf, ctx2);
should be valid if ctx1 and ctx2 have the same client API and are not
current in another thread.
|
|
Remove all _egl<Res>IsLinked and _egl<Res>IsBound. Update
_eglBindContext and drivers to do reference counting.
|
|
This is a really simple mechanism. There is no atomicity and the caller
is expected to hold the display lock.
|
|
Internally a mode belongs to a screen. But functions like
eglGetModeAttribMESA treat a mode as a display resource: a mode can be
looked up without a screen. Considering how KMS works, it is better to
stick to the current implementation.
To properly support looking up a mode without a screen, this commit
assigns each mode (of all screens) a unique ID.
|
|
Make _eglInitScreen take a display and rename _eglAddScreen to
_eglLinkScreen. Remove unused functions.
|
|
Mainly to rename _eglAddConfig to _eglLinkConfig, along with a few clean
ups.
|
|
All display resources are already initialized with a display. Linking
simply links a resource to its display.
|
|
We do not want them to be all over the places.
|
|
Avoid code duplications.
|
|
The opaque nature of EGLImage implies that extensions almost always
define their own attributes. Move attributes in _EGLImage to
_EGLImageAttribs and add a helper function to parse attribute lists.
|
|
_EGLConfig can be directly dereferenced now. Since egl_glx is the last
user of the macros, drop the macros too.
|
|
Replace SET_CONFIG_ATTRIB/GET_CONFIG_ATTRIB by direct dereferences.
|
|
This makes _EGLConfig more accessible and scales better when new
attributes are added.
|
|
Remove duplicated include.

Do not call into the driver if the extension for the called function is
not enabled.
|
|
The main use of the backend is to support EGL_MESA_drm_display. drm
should be a better name.
|
|
Remove the hard-to-get-right _eglBindContextToSurfaces. As well as fix
an assertion failure from b90a3e7d8b1bcd412ddbf2a4803de2756dacd436 when
such call sequence is hit
eglMakeCurrent(dpy, surf1, surf1, ctx1);
eglMakeCurrent(dpy, surf2, surf2, ctx2);
eglMakeCurrent(dpy, surf1, surf1, ctx1);
|
|
In other words, skip the __GLcontextModes middle man.
|
|
_EGL_CHECK_DISPLAY checks the display and returns from eglCreateContext
on error.
|
|
This fixes several NULL dereferences.
|
|
Create EGLImages from DRM buffer handles.
|
|
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).
|
|
Without the .def file, function names are decorated and cannot be
queried by GetProcAddress easily.
|
|
When _EGL_GET_CORE_ADDRESSES is defined, eglGetProcAddress can be used to query
core functions. This is non-standard, but some apps expect it.
|
|
Add new source files to SConscripts.
|
|
Individual drivers still need to support and enable the extension.

This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.
|
|
|
|
These extensions allow an application to make a context current by
passing EGL_NO_SURFACE for the write and read surface in the call to
eglMakeCurrent. The motivation is that applications that only want to
render to client API targets (such as OpenGL framebuffer objects)
should not need to create a throw-away EGL surface just to get a
current context.
|
|
The function is used by _eglGetConfigs and _eglGetScreens. The array
size should not be limited by the buffer size when the buffer is NULL.
This fixes fdo bug #29052.

Driver loading is now splitted into two stages. In the first stage, an
_EGLModule is created for each driver: user driver, default drivers, and
all files in the search directories that start with "egl_". Modules are
not loaded at this stage.
In the second stage, each module is loaded to initialize a display. The
process stops at the first module that can initialize the display.
If eglGetProcAddress is called before eglInitialize, the same code path
will be taken to find the first module that supports
EGL_DEFAULT_DISPLAY. Because we do not want to initialize the display,
drv->Probe is used instead in this case.

Fixes the build on Windows.
|
|
|
|
Windows unloads DLLs before atexit. Make _eglUnloadDrivers no-op on
Windows for now.
|
|
|
|
|
|
Dynamic arrays will be used to store configs and screens of a display.
