How much improvement are we talking here?
Is it still faster when a bswap is involved?
Thanks for pointing out.

In KVM mode the global mutex is released when vcpus are executing,
which means acquiring the fairness mutex is not required.
Also for KVM there is one thread per vcpu, so tcg_has_work is meaningless.
Add a new qemu_wait_io_event_common function to hold common code
between TCG/KVM.
With SIG_IPI blocked vcpu loop exit notification happens via -EAGAIN
from KVM_RUN.

Block and consume it with sigtimedwait on the outer vcpu loop, which

Hello all,
is there any support for 64-bit MMIO?
I'm trying to emulate 16750-like UART by adopting current 16550A emulation.
The problem is that my (MIPS) hardware is 64-bit, and native software
issues 64-bit load/stores (LD/SD) to talk with all hardware registers,
which are all 64-bit too (for

No, though there has been some discussion about it before which you
can find in the archives. 64 bit MMIO would be useful for Sparc32,

I note that the interface seems full of warts to me,
