Package: ftp.debian.org
beignet FTBFS with LLVM > 9 (#974792), and hence cannot be built in
current unstable. (The existing package probably still works, because
beignet statically links LLVM to avoid #852746, but unbuildable packages
are unreleasable by policy.)
beignet is abandoned upstream and mostly replaced by intel-opencl-icd.
Some older hardware (Ivy Bridge/Haswell) is supported by
beignet-opencl-icd but not intel-opencl-icd. This hardware can use
pocl-opencl-icd, but a rough estimate suggests that this will be ~8-16x
slower. This was raised during the discussion in #974792, and I am
CCing those people in case they want to object to removal, but they
didn't have a way to fix beignet.
