[PATCH 0/6] Raven support for KFD

[Felix Kuehling]

This patch series applies on top of my previous 25-patch series on top
of Oded's amdkfd-next branch.

On the user mode side, you need my drm-next-wip branch in
https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/tree/fxkamd/drm-next-wip.
The rest of ROCm user mode should work unmodified.

Regards,
  Felix
