Bug#881593: AMDGPU module not built for ppc64el
Package: linux-image-powerpc64le
Version:
For an unknown (historical?) reason, the AMDGPU kernel module is not built
on ppcl64el systems. I have rebuilt the kernel and verified that it does
work on POWER9 with Linux 4.14 and an AMD Vega 64 card, so the module
build should be enabled for Debian. Without this module there is no way
to get video out of the Vega cards on OpenPOWER machines.
I have attached a patch for the kernel configuration file that enables the
AMDGPU module.
