Subject: [PATCH 00/10 v7] KVM: PPC: IOMMU in-kernel handling
Date: Thu,  1 Aug 2013 14:44:22 +1000	[thread overview]
Message-ID: <1375332272-22176-1-git-send-email-aik@ozlabs.ru> (raw)

This accelerates VFIO DMA operations on POWER by moving them
into kernel.

The changes in this series are:
1. rebased on v3.11-rc3.
2. VFIO external user API will go through VFIO tree so it is
excluded from this series.
3. As nobody ever reacted on "hashtable: add hash_for_each_possible_rcu_notrace()",
Ben suggested to push it via his tree so I included it to the series.
4. realmode_(get|put)_page is reworked.

More details in the individual patch comments.

Alexey Kardashevskiy (10):
  hashtable: add hash_for_each_possible_rcu_notrace()
  KVM: PPC: reserve a capability number for multitce support
  KVM: PPC: reserve a capability and ioctl numbers for realmode VFIO
  powerpc: Prepare to support kernel handling of IOMMU map/unmap
  powerpc: add real mode support for dma operations on powernv
  KVM: PPC: enable IOMMU_API for KVM_BOOK3S_64 permanently
  KVM: PPC: Add support for multiple-TCE hcalls
  powerpc/iommu: rework to support realmode
  KVM: PPC: Add support for IOMMU in-kernel handling
  KVM: PPC: Add hugepage support for IOMMU in-kernel handling
