2013-09-02target: Include softmmu_exec.h where forgottenRichard Henderson1-0/+2
Several targets forgot to include softmmu_exec.h, which would break them with a header cleanup to follow. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-0/+2
Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized. As a quick and safe solution, move the qemu_init_vcpu() call back into the targets' realize functions.

2013-07-23cpu: Turn cpu_get_phys_page_debug() into a CPUClass hookAndreas Färber3-3/+8
Change breakpoint_invalidate() argument to CPUState alongside. Since all targets now assign a softmmu-only field, we can drop helpers cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().

2013-07-09cpu: Drop unnecessary dynamic casts in *_env_get_cpu()Andreas Färber1-1/+1
A transition from CPUFooState to FooCPU can be considered safe, just like FooCPU::env access in the opposite direction. The only benefit of the FOO_CPU() casts would be protection against bogus CPUFooState pointers, but then surrounding code would likely break, too. This should slightly improve interrupt etc. performance when going from CPUFooState to FooCPU. For any additional CPU() casts see 3556c233d931ad5ffa46a35cb25cfc057732ebb8 (qom: allow turning cast debugging off).

2013-07-09linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell1-13/+0
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU related -- they are specific to the TLS ABI for a a particular OS. Move them into the linux-user/ tree where they belong. target-lm32 had entirely unused implementations, since it has no linux-user target; just drop them.

2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber5-4/+10
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 Färber2-4/+3
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.

2013-02-01target-unicore32: Rename CPU subtypesAndreas Färber2-3/+7
In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. No functional changes for -cpu arguments.

2013-02-01target-unicore32: Mark as unmigratableAndreas Färber4-26/+9
CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a hw_error(). Therefore we can without problems suppress registration of "cpu_common" VMState by dropping CPU_SAVE_VERSION define and provide an unmigratable "cpu" VMStateDescription for UniCore32CPU at device level instead, where we can attach this the QOM way.
