Merge multiple egl_<platform>_<pipe>.so into a single
egl_gallium_<pipe>.so. The environment variable EGL_PLATFORM is now
used to modify the return value of _eglGetNativePlatform.
|
|
This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
|
|
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.
|
|
Merge _eglNewDisplay and _eglLinkDisplay into _eglFindDisplay. Remove
unused _eglUnlinkDisplay.
|
|
A display may be shared by multiple threads. Add a mutex for access
control.
|
|
|
|
Mainly to remove eglcurrent.h and egldisplay.h from eglglobals.h.
|

|
|
Reset dpy->MaxConfigs so that dpy->Configs is re-allocated.
|
|
An unlinked resource may still be a current resource such as current
surfaces. There might still be a need to know which display the
unlinked resource belongs to.
|
|
Rename Native*Type to EGLNative*Type.
|
|
This emphasizes the fact that the resource to be checked could really be
invalid and have an unknown type.
|
|
Turn _EGLSurface and _EGLContext into _EGLResource so that they can be
managed uniformly.
|
|
Resources are objects managed by a display. They can be linked to or
unlinked from a display. It is also possible to check if a resource is
valid.

Move functions to where they should be. There should be no real change
here.

Remove _eglPreloadDriver, _eglLookupDriver, and _eglSplitDisplayString.
|
|
Replace the use of _eglPreloadDriver by _eglPreloadDrivers. The latter
supports EGL_DISPLAY which have a better chance to "just work".
|
|
It is not used anymore.

libX11 is used to determine the screen number, which is in turned used
to determine the DRI driver. However, the sysfs interface for
determining the DRI driver is gone, and no working driver depends on
this mechanism.
Display string parsing is moved to a new function,
_eglSplitDisplayString.

Handle checking was done using hash tables. Now that they are gone, we
have to loop over the lists.

progs/egl/demo3.c is also changed since it uses an internal function.

The hash table was used to map a display to a handle. It is simpler to
cast directly.

Move drv->API.Terminate call to eglTerminate. Remove
_eglReleaseDisplayResource as drivers are doing it.

Driver is chosen and preloaded when eglGetDisplay is called. Later when
eglInitialize is called, the same driver is matched to initialize the
display. Also, add new, but unused, hooks to EGLDriver to allow a
driver to probe a display or unload itself.

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.

Thread infos and displays are usually not freed by applications. This
commit add atexit calls to free them.

_eglFiniDisplay is called at exit time to free allocated displays. It
is, however, not used right now.

Casting an unsigned int to or from a pointer directly gives warnings on

EGL contexts and surfaces are resources of displays. They should be
managed by displays. This commit adds a bunch of functions to
egldisplay.c to help establish the links between contexts/surfaces and
displays. How links are established is considered opaque outside
display. Functions like _eglGetSurfaceHandle or _eglLookupSurface are
therefore moved to egldisplay.c, with some small modifications.
The idea is also extended to display. That is, displays need to link to
themselves to be looked up.
This commit only adds the functions. A commit to use them should
follow.

This commit introduces a "current" system to manage per-thread info. It
uses TLS, if GLX_USE_TLS is defined, or pthread, if PTHREADS is defined.
If none of them are defined, it uses a dummy implementation that is just
like before.

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.

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