Subject: [PATCH kernel v2 0/4] KVM: PPC: Add in-kernel acceleration for 64bit DMA
Date: Tue, 1 Mar 2016 17:54:36 +1100 [thread overview]
Message-ID: <1456815280-38546-1-git-send-email-aik@ozlabs.ru> (raw)
This extends the existing H_PUT_TCE/etc in-kernel acceleration to 64bit
DMA windows mapped at addresses other than zero. This accelerates huge
DMA windows which pseries guests create using Dynamic DMA window (DDW) API.
This does not affect VFIO yet.
This is made against git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git ,
kvm-ppc-next branch.
Please comment. Thanks!
Alexey Kardashevskiy (4):
KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_64 capability number
KVM: PPC: Add @page_shift to kvmppc_spapr_tce_table
KVM: PPC: Add @offset to kvmppc_spapr_tce_table
KVM: PPC: Add support for 64bit TCE windows
