Wow this has crept up suddenly...
I'm going to braindump my "needs to be done for 4.13" list.
Before code freeze:
1) Refresh and repost MSR_VIRT_SPEC_CTRL. Still very important for perf
on AMD Fam17h hardware.
2) Put together the "skeleton set_cpu_policy" plan. This will help to
unblock some of the CPUID/MSR work, and will allow us to take
(/backport) MSR_ARCH_CAPS support, which is very critical for perf on
Intel Cascade Lake hardware.
2a) Stretch goal. See about getting MSR_ARCH_CAPS working. More likely
to be early in the 4.14 dev cycle and backport for 4.13.1
3) Stretch goal. Dust off the domain_crash() changes which have been
pending for a couple of releases now.
Blockers:
1) L1TF_BARRIER mode. What we have currently in tree takes a perf hit
while providing 0 security and breaking the ability to build livepatches
against 4.13. My plan here is to put it behind an off-by-default
Kconfig option.
2) Get the Sphinx docs licensed as CC-BY, seeing as this is the first
release with them in.
Misc ought-to-haves:
1) Refresh and repost the "Introduction" and "wishlist" docs.
2) Post the conversion of xen-command-line.pandoc to sphinx which I've
been carrying locally rather too long now.
This should get the sphinx docs into a state of having several useful
bits in, even though we haven't moved over wholesale yet.
I've probably missed some things, but this should do for now.
~Andrew
