Subject: [PATCH kernel 0/4] KVM: PPC: Add in-kernel acceleration for 64bit DMA
Date: Thu, 21 Jan 2016 19:15:22 +1100 [thread overview]
Message-ID: <1453364126-22527-1-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 depends on:
69b907297f4e list: Add lockless list traversal primitives
and recently posted:
powerpc: Make vmalloc_to_phys() public
KVM: PPC: Add in-kernel multitce handling
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
