2013-07-01KVM: Don't assume that mpstate exists with in-kernel PIC alwaysAlexander Graf1-1/+1
On PPC, we don't support MP state. So far it's not necessary and I'm not convinced yet that we really need to support it ever. However, the current idle logic in QEMU assumes that an in-kernel PIC also means we support MP state. This assumption is not true anymore. Let's split up the two cases into two different variables. That way PPC can expose an in-kernel PIC, while not implementing MP state. Signed-off-by: Alexander Graf <agraf@suse.de> CC: Jan Kiszka <jan.kiszka@siemens.com>

2013-05-02cpus: Fix pausing TCG CPUs while in vCPU threadAndreas Färber1-1/+2
Due to a preceding while loop, no CPU would've been put into stopped state. Reinitialize the variable. This fixes commit d798e97456658ea7605303b7c69b04ec7df95c10 (Allow to use pause_all_vcpus from VCPU context) for non-KVM case. While at it, change a 0 to false, amending commit 4fdeee7cd4c8f90ef765537b9346a195d9483ab5 (cpu: Move stop field to CPUState).

2013-03-12cpus: Replace open-coded CPU loop in qmp_memsave() with qemu_get_cpu()Andreas Färber1-8/+3
No functional change, just less usages of first_cpu and next_cpu fields. env is passed to cpu_memory_rw_debug(), which in turn passes it to target-specific cpu_get_phys_page_debug(). Changing both would be a larger refactoring, so defer that by using env_ptr for now. Reviewed-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16cpus.c: Drop unnecessary set_cpu_log()Peter Maydell1-12/+0
The set_cpu_log() function in cpus.c is a fairly simple wrapper which is only called from one location. Just inline the code into vl.c, since there is no need to indirect it via cpus.c and the handling of the error case is more appropriate to vl.c.
