[PATCH v3 0/2] drm: nouveau: memory coherency for ARM
v2 was doing some pretty nasty things with the DMA API, so I took a different
approach for this v3.
As suggested, this version uses ttm_dma_populate() to populate BOs. The reason
for doing this was that it would entitle us to using the DMA sync functions,
but since the memory returned is already coherent anyway, we do not even
need to call these functions anymore.
So this series has turned into

An interesting fact: if I change ttm_bo_kmap_ttm() such as kernel
mappings of BOs are always performed write-combined, and leave the
TTM_PL_TT default caching to TTM_PL_FLAG_CACHED so user-space mappings
remain cached, the corruptions just vanish. It seems to be the fact of
setting user-space mappings to anything non-cached that leads to this
puzzling behavior. Certainly some subtlety of ARM mappings are getting
over my head here.
If we need to implement different policies f...

[PATCH 0/6] Nouveau on ARM fixes
This is the first set of patches to make Nouveau work
on Tegra. Those are only the obvious correctness fixes,
a lot of optimization work remains to be done, but at least
it's enough to get accel working and let the machine survive
a piglit run.
A new BO flag is introduced to allow userspace to hint the
kernel about possible optimizations.

[RFC] Deprecate AGP GART support for Radeon/Nouveau/TTM
Unfortunately AGP is still to widely used as we could just drop support for using its GART.
Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART.
For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available.
Please comment,
Christian.
