This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.

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.

Windows unloads DLLs before atexit. Make _eglUnloadDrivers no-op on
Windows for now.
|
|
It is no longer needed.

This change makes st/egl build a single egl_gallium.so and multiple
st_<API>.so and pipe_<HW>.so. When a display is initialized, the
corresponding pipe driver will be loaded. When a context is created,
the corresponding state tracker will be loaded.
Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium,
pipe drivers and state trackers should always be distributed as a single
package. As such, there is only a single src/gallium/targets/egl/ that
builds everything for the package.
|
|
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.
|
|
A platform is already used to mean a window system in EGL. No need to
use a different term.
|
|
A platform means a native window system in EGL. Use OS that follows
Gallium instead.

Fix several portability issues and add SConscript for Windows build.

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 would do strlen(library_suffix()) in _eglLoaderFile(), with
library_suffix() returning NULL. So obviuosly not used or tested.
|
|
That is, don't dlopen(egl_glx) when we know we need to append .so.
|
|
The function can be used by a driver to check each search path of EGL.
|
|
Just follow gcc's advices here.
|
|
Lock the global mutex in _eglPreloadDrivers and _eglAllocScreenHandle.
Add comments to why certain pathes do not need locking.
|
|
|
|
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.
|
|
The driver suffix might be NULL on some platforms. Perform the matching
only when there is a suffix.
|
|
There were some refactorings with the addition of EGL_DRIVERS_PATH.
They made some platform #ifdef's unnecessary.
|
|
Specifically, ignore EGL_DRIVERS_PATH when an application is
setuid/setgid. And ignore EGL_DRIVER when there is a slash in it.
|
|
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.

|
Mainly to remove eglcurrent.h and egldisplay.h from eglglobals.h.
|
|
_eglCloseDriver is no-op and _eglOpenDriver does nothing but call
_eglMatchDriver. Export _eglMatchDriver directly.
|
|
Individual drivers still need to implement the API hooks.
|
|
Add a platform specific function to turn a library name to a library
path. It is used to convert EGL_DRIVER or the default driver to a
library path that can be loaded.
|
|
This function is not used and should have been removed by last commit.
My mistake.
|
|
With the addition egl_x11_swrast, egl_softpipe is sort of deprecated.
The new driver serves the same purpose as egl_softpipe does. It is
based on egl_g3d and provides more features.
|
|
In current design, multiple drivers will probe the same display and the
best driver is determined. The cache can be used by the drivers to
store and share the probed data.
|
|
Make drv->Probe return a score so that the matching can be done by
finding the driver with the highest score.
|
|
The macro is used to determine if dlfcn.h or dirent.h is available.
POSIX is a better name than X in such case.
|
|
Remove _eglPreloadDriver, _eglLookupDriver, and _eglSplitDisplayString.
|
|
It can be used to load the user driver specified by EGL_DRIVER, or a set
of drivers specified by EGL_DISPLAY, or the default driver, and in that
order.
|
|
This adds error checking to the synchronization primitives. And
eglWaitGL is now implemented by eglWaitClient.

This allows an EGL driver to be compiled together with libEGL.so. It
eliminates the need to specify a driver, or support module loading on
new platforms.

The real difference is that the driver suffix is now appended. This
also fixes an annoying bug that EGL_DRIVER could not specify the path to
a driver because a suffix was always appended.

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.

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

Move some fields of _EGLDriver to _EGLDisplay. It also becomes
unnecessary to pass _EGLDisplay to drivers when _eglMain is called.

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.

eglTerminate should destroy the contexts and surfaces of the display.
