This enables IOMMU for SVM. Instead of sharing
a H_PUT_TCE_INDIRECT page, this uses H_PUT_TCE for mapping
and H_STUFF_TCE for clearing TCEs which should bring
acceptable performance at the boot time; otherwise things
work with the same speed anyway.
Please comment. Thanks.
Alexey Kardashevskiy (2):
powerpc/pseries: Allow not having
ibm,hypertas-functions::hcall-multi-tce for DDW
powerpc/pseries/iommu: Do not use H_PUT_TCE_INDIRECT in secure VM
Ram Pai (1):
powerpc/pseries/iommu: Use dma_iommu_ops for Secure VM.
