Originally patch 4 was targeted for Jason's rdma tree since other HMM related changes were queued there. Now that those have been merged, these patches just contain changes to nouveau so they could go through any tree. I guess Ben Skeggs' tree would be appropriate. Changes since v2: Added patches 1-3 to fix some minor issues. Eliminated nouveau_find_svmm() since it is easily found.

Hi, just for your information and maybe for some help: with 5.1rc1 and SVM enabled i see the following backtrace [1] when the nouveau card (reverse prime) goes to sleep, for now i have papered over with [2] which leaves me with userspace hangs. Any pointers where to look for the actual culprit? PS: Card is: nouveau 0000:01:00.0: NVIDIA GP106 (136000a1) Greetings, Tobias [1]: BUG: unable

hmm_range_fault() returns an array of page frame numbers and flags for how the pages are mapped in the requested process' page tables. The PFN can be used to get the struct page with hmm_pfn_to_page() and the page size order can be determined with compound_order(page) but if the page is larger than order 0 (PAGE_SIZE), there is no indication that the page is mapped using a larger page size. To

Hi Jérôme, Ben and Jason, below is a series against the hmm tree which starts revamping the migrate_vma functionality. The prime idea is to export three slightly lower level functions and thus avoid the need for migrate_vma_ops callbacks.
