Hey,
I should know this but I am bit behind on the latest of the drm-debug
tools. Is there a way to figure out which applications are using
GEM/TTM buffers? Or just even a simpler - which application is using
which DRM pages?

That looks OK to me. And baremetal should not be

si_calculate_leakage_for_v_and_t_formula" causes a build regression:

So after a bit of irc chatting with Maarten this seems to be more
involved. The above check is to cache the dma mapping, but the
implementation is bogus in tons of ways:
- If direction changes we don't bother with unmaping and freeing the
mapping, but simply leak it.

Hey Dave
Of course I will investigate.
The SWIOTLB is unfortunately used because it is a fallback (and I am the
maintainer of it) and if a real IOMMU is activated it can be mitigated
differently. When you say 'passed through' you mean in terms of an IOMMU
in a guest?

amount of PFNs that can be combined together - but with this issue
discovered during rc7 that might be too risky.

Hey Dave, Chris, Imre,
Attached is a fix that makes v3.10-rc6 boot on Intel HD 4000 when SWIOTLB
bounce buffer is in usage. The SWIOTLB can only handle up to 512KB swath
of memory to create bounce buffers for and Imre's patch made it possible
to provide more than to the DMA API which caused it
