Subject: [PATCH kernel 00/15] powerpc/kvm/vfio: Enable in-kernel acceleration
Date: Wed, 3 Aug 2016 18:40:41 +1000 [thread overview]
Message-ID: <1470213656-1042-1-git-send-email-aik@ozlabs.ru> (raw)
This is my current queue of patches to add acceleration of TCE
updates in KVM. This has a long history and was rewritten pretty
much completely again, this time I am teaching KVM about VFIO
containers. Some patches (such as 01/15) could be posted
separately but I keep all of them here to make review easier
(if the concept turns out be wrong - then I might still want
to have 01/15).
Please comment. Thanks.
