[Qemu-devel] [CFT PATCH 00/12] Tricky parts of my iothread-for-win32 stuff

[Paolo Bonzini]

Ok, so let's start the dance...

These are the generic parts of the iothread-for-win32 work I made
last year, rebased to today's qemu (qemu-kvm.git/uq/master merged
with qemu.git/master, because it conflicts with some patches from Jan).
I never tested them too much, and that's one of the reasons why I never
submitted the stuff.  Perhaps with some help they can make it this time.

Testing I made now is still a bit limited, but the patches can boot
RHEL and Fedora under both Windows iothread and Linux iothread.  FWIW,
under Wine I need iothread to boot Linux.

The main idea is to replace timedwaits with waits.  First because the
timedwaits were such only out of laziness; second because timedwait
is a pain to implement for Win32 where we have to manually implement
condvars.

Anthony Liguori (1):
  io-thread: make sure to initialize qemu_work_cond and qemu_cpu_cond

Paolo Bonzini (11):
  cris, microblaze: use cpu_has_work
  inline cpu_halted into sole caller
  change qemu_thread_equal API to always compare with current thread
  always qemu_cpu_kick after unhalting a cpu
  exit round-robin vcpu loop if cpu->stopped is true
  always signal pause_cond after stopping a VCPU
  do not use timedwait on qemu_halt_cond
  do not use timedwait on qemu_system_cond
  do not use timedwait on qemu_pause_cond
  do not use timedwait on qemu_cpu_cond
  iothread stops the vcpu thread via IPI
