At the moment, vfio maintains a global list of containers
that are assumed to be more or less interchangeable, since
they are all set up with a MemoryListener to have all of
system memory mapped. However, that only makes sense if
all the containers are used on devices which really do
expect a dma address space identical to system memory.
This patch moves towards that by making the list of
containers per DMAContext (which corresponds to a dma
address space) instead of global.
This seems like an unnecessary intrusion into common code. Why
not create a vfio specific list of dma objects, each with a
list of containers? Thanks,
Yeah, I suggest that this is re-evaluated on top of the iommu
patches.
You can find them at git://github.com/bonzini/qemu.git, branch
iommu. It seems to work with pseries, at least my guest crashes
at the same place with and without. USB works, and so do VGA and
spapr-vscsi.
Ok, I'll have a look when I get a chance. Any guesses as to when
they might reach mainline?
If I get your Tested-by, early in 1.6.
Emulated PCI works on ppc64/spapr so far.
