Subject: [PATCH kernel v6 00/10] powerpc/kvm/vfio: Enable in-kernel acceleration
Date: Thu, 2 Mar 2017 19:56:34 +1100 [thread overview]
Message-ID: <20170302085644.41828-1-aik@ozlabs.ru> (raw)
This is my current queue of patches to add acceleration of TCE
updates in KVM.
This is based on Linus'es tree sha1 4977ab6e92e2.
Please comment. Thanks.
Changes:
v6:
* reworked the last patch in terms of error handling and parameters checking
v5:
* replaced "KVM: PPC: Separate TCE validation from update" with
"KVM: PPC: iommu: Unify TCE checking"
* changed already reviewed "powerpc/iommu/vfio_spapr_tce: Cleanup iommu_table disposal"
* reworked "KVM: PPC: VFIO: Add in-kernel acceleration for VFIO"
* more details in individual commit logs
v4:
* addressed comments from v3
* updated subject lines with correct component names
* regrouped the patchset in order:
- powerpc fixes;
- vfio_spapr_tce driver fixes;
- KVM/PPC fixes;
- KVM+PPC+VFIO;
* everything except last 2 patches have "Reviewed-By: David"
v3:
* there was no full repost, only last patch was posted
v2:
* 11/11 reworked to use new notifiers, it is rather RFC as it still has
a issue;
* got 09/11, 10/11 to use notifiers in 11/11;
* added rb: David to most of patches and added a comment in 05/11.
