2013-06-28cpu: Change qemu_init_vcpu() argument to CPUStateAndreas Färber
This allows to move the call into CPUState's realizefn. Therefore move the stub into libqemustub.a. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-06-28cpu: Turn cpu_dump_{state,statistics}() into CPUState hooksAndreas Färber
Make cpustats monitor command available unconditionally. Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec() arguments to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber
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 Färber
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>
2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell
The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount. Rename them to gen_tb_start/end.

2013-03-03cpu: Introduce ENV_OFFSET macrosAndreas Färber
Introduce ENV_OFFSET macros which can be used in non-target-specific code that needs to generate TCG instructions which reference CPUState fields given the cpu_env register that TCG targets set up with a pointer to the CPUArchState struct.

2013-02-16cpu: Add CPUArchState pointer to CPUStateAndreas Färber
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-unicore32: Move TCG initialization to UniCore32CPU initfnAndreas Färber
Normalize the "inited" logic and add a tcg_enabled() check to suppress it for qtest. Ensures that a QOM-created UniCore32CPU is usable. Acked-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-02-01target-unicore32: Rename CPU subtypesAndreas Färber
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. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-01target-unicore32: Mark as unmigratableAndreas Färber
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.

2013-01-28target-unicore32: Use type_register() instead of type_register_static()Andreas Färber
According to its documentation, type_register_static()'s TypeInfo argument should exist for the life type of the type. Therefore use type_register() when registering the list of CPU subtypes. No functional change with the current implementation. Cf. 918fd0839eeafc83bd4984364321a947d29041fe for arm. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-01-27target-unicore32: Detect attempt to instantiate non-CPU type in cpu_init()Andreas Färber
Consolidate model checking into a new uc32_cpu_class_by_name(). If the name matches an existing type, also check whether that type is actually (a sub-type of) TYPE_UNICORE32_CPU. This fixes, e.g., -cpu puv3_dma asserting. Cc: qemu-stable@nongnu.org Signed-off-by: Andreas Färber <afaerber@suse.de>
