2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber1-0/+1
This removes a global per-target function and thus takes us one step closer to compiling multiple targets into one executable. It will also allow to override the interrupt handling for certain CPU families. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber1-4/+4
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16cpu: Add CPUArchState pointer to CPUStateAndreas Färber1-0/+2
The target-specific ENV_GET_CPU() macros have allowed us to navigate from CPUArchState to CPUState. The reverse direction was not supported. Avoid introducing CPU_GET_ENV() macros by initializing an untyped pointer that is initialized in derived instance_init functions. The field may not be called "env" due to it being poisoned.

2013-02-16target-s390x: Move TCG initialization to S390CPU initfnAndreas Färber1-0/+6
Ensures that a QOM-created S390CPU is usable. Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16target-s390x: Introduce QOM realizefn for S390CPUAndreas Färber1-2/+14
Introduce realizefn and set realized = true in cpu_s390x_init(). Defer CPU reset from initfn to realizefn. Acked-by: Richard Henderson <rth@twiddle.net> [AF: Invoke parent's realizefn] Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-01Merge remote-tracking branch 'agraf/s390-for-upstream' into stagingAnthony Liguori1-1/+1
# By Andreas Färber # Via Alexander Graf * agraf/s390-for-upstream: target-s390x: Pass S390CPU to s390_{add, del}_running_cpu() target-s390x: Clean up cpu_inject_*() signatures target-s390x: Fix debug output target-s390x: Fix debug output (continued)
2013-02-01target-s390x: Pass S390CPU to s390_{add, del}_running_cpu()Andreas Färber1-1/+1
This prepares for moving the halted field to CPUState. Most call sites can already supply S390CPU, for some env becomes unused. Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-02-01target-s390x: Mark as unmigratableAndreas Färber1-1/+9
CPU_SAVE_VERSION was undefined, so "cpu_common" VMState and cpu_{save,load}() were not registered. They were no-ops. Therefore there is no backwards compatibility to keep, so we can mark S390CPU as unmigratable at device level.

2013-01-18target-s390x: Unregister reset callback on finalizationAndreas Färber1-0/+10
Since commit "s390: Add CPU reset handler" the CPU's instance_init registers a reset callback. Unregister that on instance_finalize. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-18s390: Add CPU reset handlerJens Freimann1-2/+33
Add a CPU reset handler to have all CPUs in a PoP compliant state. Signed-off-by: Jens Freimann <jfrei@linux.vnet.ibm.com> [agraf: move hw/hw.h into existing ifdef] Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-18S390: Enable -cpu help and QMP query-cpu-definitionsViktor Mihajlovski1-0/+26
This enables qemu -cpu help to return a list of supported CPU models on s390 and also to query for cpu definitions in the monitor. Initially only cpu model = host is returned. This needs to be reworked into a full-fledged CPU model handling later on. This change is needed to allow libvirt exploiters (like OpenStack) to specify a CPU model.

2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber1-1/+1
Note that target-alpha accesses this field from TCG, now using a negative offset. Therefore the field is placed last in CPUState. Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change. Move common parts of mips cpu_state_reset() to mips_cpu_reset().

2012-06-11target-s390x: Let cpu_s390x_init() return S390CPUAndreas Färber1-1/+1
Let cpu_init() return CPUS390XState for backwards compatibility. Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-04-04target-s390x: Update s390x_{tod,cpu}_timer() to use S390CPUAndreas Färber1-2/+2
In place of CPUS390XState pass S390CPU as opaque from the new initfn. cpu_interrupt() is anticipated to take a CPUState in the future. Signed-off-by: Andreas Färber <afaerber@suse.de> Tested-by: Christian Borntraeger <borntraeger@de.ibm.com>
