[Beignet] [Solved] Re: cl_khr_gl_sharing stopped working

[Orm Finnendahl]

Hi Benson,

 thanks for the info. The source your mentioning is outdated
(ca. 2016): beignet has since been moved to the official Arch repos
and is maintained there.

I finally got it working by trying to rebuild previous versions of
Arch's beignet package and resolving its dependencies.

For the record (if someone else needs that on Arch):

To get both, a working opencl compiler and cl_khr_gl_sharing I
downgraded to the following packages (use the "downgrade" program from
arch repos):

- llvm 8.0.1-3
- llvm-libs 8.0.1-3
- clang 8.0.1-1
- beignet 1.3.2+12+gfc5f430c-2

This currently seems to be the latest package that is working. I
posted a bug report for arch's beignet package. Basically the
maintainer simply patches the beignet sources to work with the last
version of llvm whenever a new major version is integrated into
Arch. I have no idea what breaks the gl-sharing with llvm9 (would be
great to know). Strangely enough rebuilding previous beignet drivers
with the previous llvm versions using the original scripts and
packages on my machine resulted in cl_khr_gl_sharing not reported by
clinfo...
