Timing is not really good for this, but deferring to the next meeting is
also too long. I realize everyone's quite busy, and I'm myself also
struggling to get to look at
- VMX MSRs policy for Nested Virt: part 1 (I've looked over this, and I
  think it's okay, but I also think that in particular nested stuff wants
  both maintainers and Andrew to look over)
- vpci: add support for SR-IOV capability
- paravirtual IOMMU interface
- x86/domctl: Save info for one vcpu instance
- SSBD AMD via LS CFG Enablement
and not to speak of "add vIOMMU support with irq remapping function
of virtual VT-d". I'm however myself as well in an increasingly awkward
position to do / post further work, due to there being patch series
stalled in part from long before the 4.11 freeze (listing only series here,
there are also individual stalled patches):
- x86: improve PDX <-> PFN and alike translations
- x86: assorted assembly related cleanup
- x86: indirect call overhead reduction
- x86/HVM: implement memory read caching
- x86: more power-efficient CPU parking
And I'm not even daring to guess what is going to happen to the AVX512
patches that I have in the works for the emulator.

Bottom line - I think we need to talk about how we mean to unblock
large chunks of work.

Jan
