I think we have that now, I'm running a hmm.git that is clean and can be used for merging into DRM related trees (and RDMA). I've commited to send this tree to Linus at the start of the merge window. See here: https://lore.kernel.org/lkml/20190524124455.GB16845@xxxxxxxx/ The tree is here: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/log/?h=hmm However please consult with me before making a merge commit to be co-ordinated. Thanks I see in this thread that AMDGPU missed 5.2 beacause of the co-ordination problems this tree is intended to solve, so I'm very hopeful this will help your work move into 5.3! > Maybe having Jerome's latest HMM changes in drm-next.
