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.
Matthew Ogilvie (6):
fix some debug printf format strings
vl: fix -hdachs/-hda argument order parsing issues
qemu-options.hx: mention retrace= VGA option
vga: add some optional CGA compatibility hacks
i8259: fix so that dropping IRQ level always clears the interrupt
request
i8259: refactor pic_set_irq level logic
