There's similar code in udl, [1] which still uses writecombine for
imported buffers. Virtio does not need this?
Aside from this, do you think we could handle all special cases...

TTM/Nouveau cleanups
Hi guys,
I've already send this out in September last year, but only got a response from Daniel.
Could you guys please test this and tell me what you think about it?
Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework.
Thanks,
Christian.

[PATCH 1/2] drm/nouveau: move io_reserve_lru handling into the driver
...f concurrent
faults will all fail because they're all removed themselves from the lru,
so can't see anyone else to throw out?
Same problem really that ttm had (well still has I think for !amdgpu) with
its other lru ...
Or am I getting totally lost again here?

[Patch RFC] nouveau accelerated on Xen pv-ops kernel
Hi,
Following is a simple patch that is needed in nouveau to get
accelerated X on a Xen dom0 pv_ops kernel. The kernel is jeremy's
2.6.31.6 as of 20100222. The whole gpu tree of nouveau (which is
almost the mainline merge), was substituted into the kernel-tree.
All components of X (mesa, Xorg-server-7.5, xf86-nouveau, libdrm) used
of the same day.
