KPTI to-do list

  • Nicer way to generate MACHCPU_PAD? Maybe break the structs up?
  • int $8 push logic: use addr instead of zero at (%rsp), maybe? seems hacky.
  • Copyrights and cstyle and shiz
  • loader support for kpti=0 flag?
  • verbose boot message confirming kpti status

Testing to-do list

  • Exhaustive trap tester
  • Test weird floating point things like #XM, #MF and so on
  • Test NMI in bad situations (maybe put an infinite loop in a trampoline?)
  • Find a box that takes MCEs a lot
  • #BR?

@alaslums I'm sorry to hear that :| Would you mind filing a bug about it on the illumos-joyent github? I guess we'll come back to that some time in the future. Hopefully we haven't broken it any more than it already was, anyway.

@arekinath I'm not sure there's any benefit in maintaining/keeping Solaris 10 binary compatibility in illumos given that we're probably the only people using it ;-) We're not fussed about it as we only have a few zones that are due to be decommissioned.

I'm also not sure about filing an illumos bug on this as I don't have the technical information to hand regarding whether the issue relates to the Joyent fork of illumos specifically or is in illumos proper. "Solaris 10 Zone compatibility possibly broken" sounds a little vague ;-)
