What's irqcontrol?
uio accepts 32 bit writes to the char device file. We can encode
the fd number there, and use the high bit to signal assign/deassign.
Ugh. Very unexpandable.

It currently fails on any non-4 byte write.
So if we need more bits in

Aren't ioctls a lot simpler?
Multiplexing multiple functions on write()s is just ioctls done uglier.
I don't have an opinion here.
Writes do have an advantage that strace can show the buffer
content without being patched.

Unfortunately ioctl numbers don't always follow that rule :-(
But maybe that's just awful proprietary drivers that I've seen.
Anyway, strace

Hi, all,
This is KVM biweekly test result against kvm.git:
0e8e9adf792446859d6906af7f09249e4d0971d7 and qemu-kvm.git:
79fdb980fa4fe40c3fba9391b83b655045af030f.
Lastest KVM based on kernel 2.6.34-rc2. There is one issue that 32PAE Windows
guest can not boot up with acpi on.
