Change caf108bc58790 ("hw/i386/acpi-build: Add ACPI PCI hot-plug methods to

will always be zero. Fixes the encoding for VPSLLVQ and VPSRLVQ.

All targets call TCGCPUOps::cpu_exec_interrupt() from sysemu code.
Move its declaration to restrict it to system emulation.
Extend the code guarded.
Restrict the static inlined need_replay_interrupt() method to
avoid a "defined but not used" warning.

Why does Qemu need a new Wayland UI backend?
The main reason why there needs to be a plain and simple Wayland backend
for Qemu UI is to eliminate the Blit (aka GPU copy) that happens if using
a toolkit like GTK or SDL (because they use EGL). The Blit can be eliminated
by sharing the dmabuf fd -- as

This is the major portion of handle_cpu_signal which is specific
to tcg, handling the page protections for the translations.
Most of the rest will migrate to linux-user/ shortly.

Split out two functions into linux-user/host/arch/host-signal.h.
Since linux-user requires a linux host, drop all of the BSD and

the current blanks there are filled.

There is nothing target specific about this. The implementation
is host specific, but the declaration is 100% common.

Thanks for pointing me to the toolchain. I'll give it a try to see how it
works.
However, I'm more interested in being able to use qemu-hexagon as shown in my
example below (QuRT).
Is it possible? What kind of modifications qemu would require to make it happen?
Cheers,
Lukasz.
