Daniel: is the aim to stay _current_ or stay _stable_?
current -> track master
stable -> track most recent OE release
Ross: master can be pretty unstable
Eric: preference for stable
Rich: future aim would be to be able to use master, but since test capacity is limited, using stable at present makes most sense.
Eric: release after Morty is due April 2017.
[summarizing: uprev will be to Morty; can consider beyond that at a later time if necessary.]
OpenEmbedded upstream: meta-virtualization
meta-virtualization is tracking Xen 4.7 at the moment.
Ross: noone has yet signed up to spearhead the move to meta-virtualization.
Daniel: Apertus cares about getting to meta-measured for TPM 2.0.
Machon: meta-virt and next-version Xen are not current priorities.
Rich: Maybe with the next hardware generation?
Machon: Xen 4.6 can already handle items on current priority list.
Rich: UEFI and nesting?
Ross: not sure. Will likely be able to use existing Xen 4.6 UEFI support.
[discussion re: several TPM stacks; only 1 implements TCG spec]
Ross: AIS plans to work on TPM 1.2 and 2.0 support. tboot claims support for TPM 2.0 but have not tested it yet.
Rich: there are multiple TPM2 specs -- which will we use?
Machon: there is only one TPM2 spec (TCG) but multiple implementations from large companies.
Daniel: is AIS using Phil Tricca's TPM2 stack in meta-measured?
Rich T: Still investigating. Chris Rogers is leading TPM 2.0 work. Goal is to post RFC by end of the year.
Ross: TPM2 discussion and RFC to continue in public.
OpenEmbedded upstream: meta-secure-env
WindRiver project. Plan is to use TXT and meta-measured.
Rich: aim to share code and benefit from upstream testing.
Objective to get Measured Launch included in products from that project.
Maintainer is Bruce Ashfield, also maintainer of meta-virtualization.
Xen upstream: v4v improvements
Eric: worked on Linux module for guest VMs. Of less interest to upstream than hypervisor code.
Ross: haven't worked on hypervisor code since the 6.0 release.
Christopher: hypervisor v4v work not likely to advance imminently as preempted by other priorities, but work should incorporate changes from the v9 (last round reviewed with Xen upstream) and v10, incrementally to enable reasoning about each change in git.
Rich Turner: AIS team could contribute.
Also looking at SRIOV: could contribute upstream and post to the community when have something working.
Re: AIS display manager: actively working on the next version of display handler, called "vglass" and will work with customer re: delivering it as Open Source.
