This should be now upstream with

commit 78a121d82da8aff3aca2a6a1c40f5061081760f0

drm/nouveau/core: use vzalloc for allocating ramht

Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a
fairly sizeable chunk of memory to be allocated, which may not be
available with kzalloc. Since this is done fairly rarely (once per
channel), use vzalloc instead.

Zlatko - I didn't realize (or perhaps totally forgot) you had provided the same
patch, didn't mean to steal credit or anything like that. Just ran into the
same issue myself and sent a patch. In the future, feel free to send patches to
the mailing list.

This issue should be resolved in v4.6-rc1+.

FYI: Ilia Mirkin submitted the patch from Comment 4 to the Nouveau listserv on
6 Mar 2016. I think I'll apply this patch to my 4.4.7 kernel.

I take it back. Looking into the source code, the allocation is happening in
nvkm_ramht_new(…), which is allocating a struct nvkm_ramht containing a
variably-sized array of struct nvkm_ramht_data elements. As these elements, in
turn, contain pointers, it seems very unlikely that they'd be DMA'd, so
presumably the struct nvkm_ramht doesn't need to be physically contiguous and
could safely be allocated by vzalloc(…).

I would venture a guess that the memory allocated for a GPU FIFO buffer needs
to be physically continuous, as it will be used for DMA, so using vmalloc is a
bad idea that may lead to incorrect pages being read/written by DMA.

Aside: Does this bug report belong on this bug tracker, or would it be more
appropriate on the kernel bug tracker? This is a problem in

Use vzalloc instad of kzalloc in nvkm_ramht_new()

I've had lots of success using the attached patch. 4 days and still running
strong, no page allocation failures. But, some core developer should probably
confirm that using vmalloc instead of kmalloc is ok in that function.

I have seen this one as well on my G96 and MCP79, running 4.3.3. It seems to
happen once RAM has been filled (should it be with buffers kept around or by
applications currently running), even if SWAP is completely empty.
