[Qemu-devel] [PATCH uq/master v3 0/2] correctly reset the CPU on INIT interrupts

[Qemu-devel] [PATCH uq/master v3 0/2] correctly reset the CPU on INIT interrupts

[Paolo Bonzini]

These patches finally implement INIT entirely in userspace.  The problem
here was that the CPU was being reset after kvm_arch_reset_vcpu is called.
This made it harder to hook into the reset process and put APs into
KVM_MP_STATE_INIT_RECEIVED state (instead of KVM_MP_STATE_UNINITIALIZED
which is the state after a system reset).

In this series, patch 1 removes the kvm_arch_reset_vcpu from the generic
code, and moves it into each architecture's CPU reset callback (half of
our supported architectures do not need the callback anyway).

With this in place, patch 2 can add a similar x86-specific callback that
is used after an INIT reset.  Apart from this callback, the code for
INITs is shared entirely between the userspace irqchip and in-kernel
irqchip cases.

v2->v3: add stub kvm_arch_reset_vcpu for s390

  kvm: reset state from the CPU's reset method

[Qemu-devel] [PATCH uq/master v3 1/2] kvm: reset state from the CPU's reset method

[Paolo Bonzini]

Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset.  Using qemu_register_reset
as we do now keeps them far apart.

Fine with me.

Have you tested whether i386 needs a similar stub on non-x86? If so then

Reviewed-by: Andreas Färber <afaerber@suse.de>

For anyone else wondering, arm and ppc are no longer calling the
kvm_arch_ function, so it can get removed there, while i386 and s390x
call it from X86CPU/S390CPU reset handler now. Would be more clear if
the commit message was more verbose ;) and would be nice to clean this
up as follow-up by renaming to kvm_x86_... and kvm_s390_... or so
respectively.

It doesn't need it, because the prototype is declared always in kvm_i386.h.

I didn't test non-x86, but I tested an alternative patches that places
s390's kvm_arch_reset_vcpu prototype outside "#ifdef CONFIG_KVM".  That
also compiled fine on non-s390, and it's what will happen when compiling
on non-x86.

I figured that the dummy inline definition was closer in style to the
existing s390 code, so that's what I chose for submission.

You added stub to s390, but not to x86. It will compile either way with

Because I kept it consistent within the file.  s390 prefers stubs, x86
prefers no stubs.
