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
subdirectories. Will require an additional commit.

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.

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.
|
|
|
|
Just follow gcc's advices here.
|
|
The macros give warnings when compiled with -pedantic. This commit is
based on a patch by Brian Paul, with minor changes to add do {} while(0)
and rename the check macros.
|
|
Lock the global mutex in _eglPreloadDrivers and _eglAllocScreenHandle.
Add comments to why certain pathes do not need locking.
|
|
This gives a simple access control to the display. It is potentially
slow, but a finer grained mutex can always be used in the future. The
benefit of this simple approach is that drivers need not to worry about
thread-safety.
|
|
Merge _eglNewDisplay and _eglLinkDisplay into _eglFindDisplay. Remove
unused _eglUnlinkDisplay.
|
|
A display may be shared by multiple threads. Add a mutex for access
control.
|
|
Use macros to record the status of the function call before returning.
This is the only way that eglGetError can return the status of the most
recent function call.
|
|
The error code denotes the success or failure of the most recent
function call. A call to _eglError should always update the error code.
|
|
Replace all uses of _EGL_DECLARE_* and _eglCheck* by _EGL_CHECK_*.
|
|
Add _EGL_CHECK_* which will replace _EGL_DECLARE_* for error checking.
Move _eglCheck* earlier in the file so that the macros and the functions
are grouped together.
|
|
Small optimization.
