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.

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.
|
|
The extension defines eglGetDRMDisplay that creates an EGLDisplay from a
DRM fd. Calling eglCreateWindowSurace or eglCreatePixmapSurface with
such displays will generate EGL_BAD_NATIVE_WINDOW or
EGL_BAD_NATIVE_PIXMAP.
|
|
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.
|
|
Define PUBLIC to __declspec(dllexport) when _MVC_VER is defined.
|
|
eglplatform.h no longer defines int32_t.

It always returns a valid xcb_connection_t, but if connection failed, it's in the
error state.

Drivers need symbols from libEGL. Without back-linking, the build fails
on Cygwin.

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.

This extension adds a new function which provides an alternative to
eglSwapBuffers. eglSwapBuffersRegionNOK accepts two new parameters in
addition to those in eglSwapBuffers. The new parameters consist of a
pointer to a list of 4-integer blocks defining rectangles (x, y,
width, height) and an integer specifying the number of rectangles in
the list.

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.
|
|
Don't want to shutdown everything if egl_dri2 fails to initialize.
|
|
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.
|
|
Otherwise testing ->Probe for non-NULL and calling it goes boom.
|
|
There are enough EGL modules that they deserve a subdirectory, to avoid
polluting $(TOP)/$(LIB_DIR).
|
|
The function can be used by a driver to check each search path of EGL.
|

Move glapi to src/mapi/{glapi,es1api,es2api}.

progs/egl/Makefile is gone on master with the egl demos split into

eglplatform.h pulls in Xlib.h on X11 platforms. Likewise, the egl glx
driver and egl programs needs to link to libX11. Make sure we use the
locations the user told us about.

This patch amends the error output string for the case where the
dri2 egl driver could not open the dri dev node.

Forgot to set the enabled bit when I implemented the extension.

DRI does not define any callback to flush the current context. GLX
loader simply calls glFlush. Follow the GLX loader here.

The last commit incorrectly moved the code under an "else".

0a82fadcdd0b6ebbc345c7c302da0e0efce40a98 seems to trigger a bug in
_eglBindContext. Rework the logics yet again. It is simpler, and
hopefully correct this time.
|
|
There is no effective changes given how the function is called. It is
still not trivial, but it should be more readable and resemble
_eglBindContextToThread a lot.
|
|
When a newly bound context is the same as the previously bound one,
_eglBindContextToThread should still return the context instead of NULL.
This gives the driver a chance to flush the context.
