[PATCH] nouveau/hmm: fix nouveau_dmem_chunk allocations
In nouveau_dmem_init(), a number of struct nouveau_dmem_chunk are allocated
and put on the dmem->chunk_empty list. Then in nouveau_dmem_pages_alloc(),
a nouveau_dmem_chunk is removed from the list and GPU memory is allocated.
However, the nouveau_dmem_chunk is never removed from the chunk_empty
list nor placed on the chunk_free or chunk_full lists. This results
in only one chunk ever being

[PATCH] gpu/nouveau: empty chunk do not have a buffer object associated with them.
From: Jérôme Glisse <jglisse at redhat.com>
Empty chunk do not have a bo associated with them so no need to pin/unpin
on suspend/resume.
This fix suspend/resume on 5.1rc1 when NOUVEAU_SVM is enabled.

Nouveau dmem NULL Pointer deref (SVM)
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)

dev_pagemap related cleanups v2
Hi Dan, Jérôme and Jason,
below is a series that cleans up the dev_pagemap interface so that
it is more easily usable, which removes the need to wrap it in hmm
and thus allowing to kill a lot of code
Note: this series is on top of the rdma/hmm branch + the dev_pagemap
releas fix series from Dan that went into 5.2-rc5.
