While testing QMP on qemu-kvm I found that it's not emitting basic

Yes. Integer promotion does guarantee sign extension.

Sounds logical - do you have numbers on the improvement?
Sure. The patch showed approximately 3-7 times speed up when measured with
rdtsc. The test environment and detailed results are described below.

Previous advice (to me and others) was to use -usbdevice tablet. I've

Right now MMIO access can only happen for GPRs and is at most 32 bit wide.
That's actually enough for almost all types of hardware out there.
Unfortunately, the guest I was using used FPU writes to MMIO regions, so
it ended up writing 64 bit MMIOs

Since we need to fill our registers by hand when doing MMIO, we also need
to sign extend manually.
