When --enable-shared-glapi is specified, libGL will share libglapi with
OpenGL ES instead of defining its own copy of glapi. This makes sure an
app will get only one copy of glapi in its address space.
The new option is disabled by default. When enabled, libGL and libglapi
must be built from the same source tree and distributed together. This
requirement comes from the fact that the dispatch offsets used by these
libraries are re-assigned whenever GLAPI XMLs are changed.
For GLX, indirect rendering for has_different_protocol() functions is
tricky. A has_different_protocol() function is assigned only one
dispatch offset, yet each entry point needs a different protocol opcode.
It cannot be supported by the shared glapi. The fix to this is to make
glXGetProcAddress handle such functions specially before calling
_glapi_get_proc_address.

Fix undefined symbol wrapper_sw_winsys_dewrap_pipe_screen.

With core mesa doing runtime API checks, GLES overlay is no longer
needed. Make --enable-gles-overlay equivalent to --enable-gles[12].
There may still be places where compile-time checks are done. They
could be fixed case by case.

When the application is not linked to any libGL*.so, loading st_GL.so
would give
/usr/local/lib/egl/st_GL.so: undefined symbol: _glapi_tls_Context
In that case, load libGL.so and try again. This works because
util_dl_open loads with RTLD_GLOBAL.
Fix "clear" OpenGL ES 1.1 demo.

When the name of the module is NULL, the process itself is dlopen()ed.
Do not print
libEGL debug: searching for st module (null)

API_DEFINES is the defines for libmesagallium.a. Append it to
egl_CPPFLAGS only when st_GL.so, which uses libmesagallium.a, is built.

Ensure -L$(TOP)/$(LIB_DIR) (the staging dir for build products), appears
in the link line before any -L in $LDFLAGS, so that we link driver we are
building with libEGL we have just built, and not an installed version
[olv: make a similar change to targets/egl]

Instead of having a NAME_SOFTWARE check just use the GALLIUM_DRIVER
instead but set the default to native which is the same as not wrapped.

Otherwise, applications compiled with C compiler might have trouble
using them.
|

Be defensive.
|
|
They are no longer used.

Replace all uses of ST_API_OPENGL_ES{1,2} by profiles. Having 3
st_api's to provide OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is not a
sane abstraction, since all of them share glapi for current
context/dispatch management.

drm_driver_descriptor::driver_name is defined to be the name of the
kernel module. We should check against drm_driver_descriptor::name
instead of drm_driver_descriptor::driver_name.

KNOWN ISSUE: eglShowScreenSurfaceMESA in st/egl/kms fails
but st/egl/x11 works
|
|
st/egl/x11/x11_screen.c requests a driver named r300 not radeon
KNOWN ISSUE: breaks st/egl/kms/
st/egl/kms requests a pipe named "radeon"
that will not be found now
so why not leaving pipe_radeon there?
that was possible as long we have only r300g.
now there is also r600g for which st/egl/kms also
requests a pipe named "radeon"
(possible solution in later commit)

Use DRI_LIB_DEPS when linking GL/GLES state trackers. This fixes
missing talloc symbol errors, and is hopefully more future proof.

There is no libdl on FreeBSD. Based on patch from Thinker
<thinker@branda.to>, which is against 7.8.
This fixes fdo bug #29093.

The target supports OpenVG on Windows with software rasterizer. The
egl_g3d_loader defined by the target supports arbitrary client APIs and
window systems. It is the SConscript that limits the support to OpenVG
and GDI.
This commit also fixes a typo in gdi backend.

Also fix pipe_radeon.so not building

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.

Several changes are made. libegl.a no longer defines _eglMain. It
defines functions to create and destroy a _EGLDriver instead. The
creation function is called by the targets. It takes an egl_g3d_loader
as its argument. The loader is defined by the targets and is in charge
of creating st_api and pipe_screen. This allows us to move the module
loading code to targets. Lastly, the modules are now loaded as the
respective contexts are created.
|
|
Merge all targets into targets/egl/. The target produces
egl_gallium_<HW>.so for each pipe driver and st_<API>.so for each client
APIs. This enables us to further merge egl_gallium_<HW>.so into
egl_gallium.so later.
