RFC v1 was posted here [1]. As I was testing more and fixing the
issues, I realized its clean to have the table_group_ops implemented
the way it is done on PowerNV and stop 'borrowing' the DMA windows
for pSeries.
This patch-set implements the iommu table_group_ops for pSeries for
VFIO SPAPR TCE sub-driver thereby enabling the VFIO support on POWER
pSeries machines.
Wait, did they previously not have any support?
Again, this TCE stuff needs to go away, not grow. I can grudgingly
accept fixing it where it used to work, but not enabling more HW that
never worked before! :(
