Revert "egl: Check if API is supported when using eglBindAPI."

This reverts commit e8b38ca202fbe8c281aeb81a4b64256983f185e0.

It broke Glamor for Gallium at least.


It exposed a bug in glamor, which is fixed by

https://patchwork.freedesktop.org/patch/91214/


So what route should we take?

Wait for the distros to catch up and enable it then, again?

I was fallen in this, too.

openSUSE 13.2 / Leap 42.1

/usr/bin/Xorg: symbol lookup error:
/usr/lib64/xorg/modules/drivers/radeon_drv.so: undefined symbol:
exaGetPixmapDriverPrivate

The commit caused Glamor to fail with:
(WW) glamor0: Failed to get GLSL version

We can't just kill Glamor support with a Mesa commit.

Why do released versions of xserver/glamor have to work with unreleased
versions of Mesa?

Just as another data point, the oibaf and padoka PPAs for Ubuntu have updated Mesa and DDX packages, but no updated xserver.

- keep the current eglBindAPI behavior forever

So because we haven't been following the EGL spec, allowing broken EGL
apps to work by accident, we have to preserve that bug forever? I'm not
buying it.


To me, the bigger issue with the change you reverted was that it caused
the piglit test spec@egl_khr_fence_sync to hang. Has anyone looked into
that?
