Subject: [PATCH v2 00/18] powernv: vfio: Add Dynamic DMA windows (DDW)
Date: Wed, 23 Jul 2014 13:05:46 +1000 [thread overview]
Message-ID: <1406084764-24685-1-git-send-email-aik@ozlabs.ru> (raw)
This prepares existing upstream kernel for DDW (Dynamic DMA windows) and
adds actual DDW support for VFIO.
This patchset does not contain any in-kernel acceleration stuff.
This patchset does not enable DDW for emulated devices.
Changes:
v2:
* moved "Account TCE pages in locked_vm" here (was in later series)
* added counting for huge window to locked_vm (ugly but better than nothing)
* fixed bug with missing >>PAGE_SHIFT when calling pfn_to_page
Alexey Kardashevskiy (18):
powerpc/iommu: Fix comments with it_page_shift
KVM: PPC: Use RCU when adding to arch.spapr_tce_tables
KVM: PPC: Account TCE pages in locked_vm
vfio: powerpc: Move locked_vm accounting to a helper
powerpc/powernv: Use it_page_shift for TCE invalidation
powerpc/powernv: Use it_page_shift in TCE build
powerpc/powernv: Add a page size parameter to
pnv_pci_setup_iommu_table()
powerpc/powernv: Make invalidate() callback an iommu_table callback
powerpc/spapr: vfio: Implement spapr_tce_iommu_ops
powerpc/powernv: Convert/move set_bypass() callback to
take_ownership()
powerpc/iommu: Fix IOMMU ownership control functions
powerpc/iommu: Fix missing permission bits in
iommu_put_tce_user_mode()
powerpc/iommu: Extend ppc_md.tce_build(_rm) to return old TCE values
powerpc/powernv: Return non-zero TCE from pnv_tce_build
powerpc/iommu: Implement put_page() if TCE had non-zero value
powerpc/powernv: Implement Dynamic DMA windows (DDW) for IODA
vfio: Use it_page_size
vfio: powerpc: Enable Dynamic DMA windows
