This is based off of Linus' master branch at
c8a0739b185d11d6e2ca7ad9f5835841d1cfc765
Configs are at
https://git.kernel.org/pub/scm/linux/kernel/git/jwboyer/fedora.git/commit/?h=rawhide&id=0be14662c54f49b4e640868b9d67df18d39edff0
Looks like a TTM regression due to:
0284f1ead87463bc17cf5e81a24fc65c052486f3
drm/ttm: add transparent huge page support for cached allocations v2
If the driver requests dma32 pages, we can end up trying to alloc
huge
dma32 pages which triggers the oops. The bochs driver always requests
dma32 here.
I'll send a rough patch once I boot it.
Dave.
Hi Dave,
fyi only: It looks like this is not the only regression in this
cycle with
ttm, novueau seems to suffer as well [1].
Adding ttm folks. Might be useful if we have an entry for ttm in
MAINTAINERS ...
-Daniel
A bit more of investigation for the nouveau regression: This only
show when Transparent Hugepages (CONFIG_TRANSPARENT_HUGEPAGE) are
enable. Thanks Dave for pointing me to that!
Yeah, sorry for that. I missed to handle the DMA32 case with
transparent huge page support.
Dave already came up with a fix which should be already submitted.
Christian.
Hi Christian,
no problem, rc1 isn't even released, so hitting bugs is expected! Yet
Daves fix ("drm/ttm: don't attempt to use hugepages if dma32 requested
(v2)" [1]) is not enough to fix the problem and a similiar backtrace to
the one posted below in my first replay to this thread can be observed
with Daves patch applied [2].
Greetings,
Tobias
