Does it work on x86? Never tried amdgpu on x86. It did work with the "radeon" driver on x86, and *mostly* works with "radeon" on POWER9 as well (except that it limits itself to 32-bit DMA for some reason, and eventually crashes when I bump up against the allocation limit; to workaround that, I am currently using the fbdev Xorg driver with the radeon kernel driver). -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
