[Qemu-devel] [PATCH qemu 0/3] spapr/iommu: Enable in-kernel TCE accelera


From: Alexey Kardashevskiy
Subject: [Qemu-devel] [PATCH qemu 0/3] spapr/iommu: Enable in-kernel TCE acceleration via VFIO KVM device
Date: Tue, 2 Jan 2018 16:28:02 +1100

This is my current queue of the in-kernel TCE acceleration
enablement.

Changes since 
https://lists.gnu.org/archive/html/qemu-devel/2017-12/msg01918.html :
* 3 patches instead of one, one per maintainership area;
* added memory_region_iommu_get_attr();
* removed set_attr() as there is no use for it now;
* folded the chunk in vfio_listener_region_add() under
VFIO_SPAPR_TCE_v2_IOMMU branch as the acceleration is only
enabled when DMA memory is preregistered and this is only supported
by the v2 IOMMU.

This is based on sha1
ad59cde C├ędric Le Goater "target/ppc: more use of the PPC_*() macros".

Please comment. Thanks.
