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?
- 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.
Fully agree behind that one.
On the overall topic here is a (related) idea I've had lying around:
- Contact distribution maintainers to patch their glamor packages as
far back as possible.
Having a mesa-maintainers ML or alike might help, they are likely to
miss this in mesa-dev, plus pinging individuals does not scale.
- Decide on transition period, where we'll have a) the patch reverted
or b) a glamor hack in place.
- Transition period is over - patch is back in/hack is out.
The communication medium can be used to get the maintainers attention
to other topics that directly concern them. They could also voice
their like/dislike towards X and Y.
How does the above sound ?
A transition period makes a lot of sense. Wanted to also add that
there's one earlier similar case where Mesa exposes GL_OES_EGL_image (ES
extension) on desktop GL just because of glamor/Xwayland:
