[Qemu-devel] [PATCH v5 0/6] Running Microport UNIX (ca 1987)

[Matthew Ogilvie <mmogilvi_qemu@miniinfo.net>]

Changes since previous version:

   * The first 4 patches haven't changed since version 3.
   * New patch 5: The 8259 patch has been totally redesigned again, this
     time based on a new understanding that on real hardware, if
     the trailing edge of an interrupt arrives before the interrupt
     is serviced, then it cancels the interrupt, just like a level
     triggered interrupt.  See earlier email discussion.
   * New patch 6 just refactors the code (no functionality change)
     after the one line fix in patch 5.

I'm also sending a couple of patches for related projects, separately:

   * Two KVM (Linux kernel) patches that do roughly the same thing as
     patches 5 and 6, only for the in-kernel PIC.
   * A patch for the kvm-unit-tests project that adds a test case
     to demonstrate the trailing edge behavior.
