Any chance you can try a newer kernel? Somebody else (also @huawei.com
incidentally) reported just this week on the mesa-dev mailing list that
the amdgpu driver in the Ubuntu 4.13 kernel is working on an arm64 platform.

If a newer kernel still doesn't work on your platform, please provide
the full dmesg output.


BTW, in the other thread it was reported that Mesa has bugs which can be
worked around by compiling it with -fsigned-char.
