Subject: [PATCH kernel v2 0/4] Enable IOMMU support for pseries Secure VMs
Date: Mon, 16 Dec 2019 15:19:20 +1100 [thread overview]
Message-ID: <20191216041924.42318-1-aik@ozlabs.ru> (raw)
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.
This is based on sha1
37d4e84f765b Linus Torvalds Merge tag 'ceph-for-5.5-rc2' of git://github.com/ceph/ceph-client
Please comment. Thanks.

powerpc/pseries: Allow not having
ibm,hypertas-functions::hcall-multi-tce for DDW
powerpc/pseries/iommu: Separate FW_FEATURE_MULTITCE to put/stuff
features
powerpc/pseries/svm: Allow IOMMU to work in SVM
