2016-05-19target-xtensa: make cpu-qom.h not target specificPaolo Bonzini
Make XtensaCPU an opaque type within cpu-qom.h, and move all definitions of private methods, as well as all type definitions that require knowledge of the layout to cpu.h. Conversely, move all definitions needed to define a class to cpu-qom.h. This helps making files independent of NEED_CPU_H if they only need to pass around CPU pointers.

2016-05-19cpu: make cpu-qom.h only include-able from cpu.hPaolo Bonzini
Make cpu-qom.h so that it is only included from cpu.h. Then there is no need for it to include cpu.h again. Later we will make cpu-qom.h target independent and we will _want_ to include it from elsewhere, but for now reduce the number of cases to handle.

2015-03-07target-xtensa: implement do_unassigned_access callbackMax Filippov
Depending on access type raise either InstrPIFDataError or LoadStorePIFDataError exception. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2014-06-05softmmu: make do_unaligned_access a method of CPUPaolo Bonzini
We will reference it from more files in the next patch. To avoid ruining the small steps we're making towards multi-target, make it a method of CPU rather than just a global. Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-07-27cpu: Introduce CPUClass::gdb_{read,write}_register()Andreas Färber
Completes migration of target-specific code to new target-*/gdbstub.c. Acked-by: Michael Walle <michael@walle.cc> (for lm32) Acked-by: Max Filippov <jcmvbkbc@gmail.com> (for xtensa) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-26target-xtensa: Introduce XtensaCPU subclassesAndreas Färber
Register a CPU type per core registered. Save the XtensaConfig in XtensaCPUClass and copy it from there to CPUXtensaState, to avoid touching every env->config access for now. Prepares for storing per-class GDB register count. Acked-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-23cpu: Turn cpu_get_phys_page_debug() into a CPUClass hookAndreas Färber
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(). Prepares for changing cpu_memory_rw_debug() argument to CPUState. Acked-by: Max Filippov <jcmvbkbc@gmail.com> (for xtensa) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-09cpu: Drop unnecessary dynamic casts in *_env_get_cpu()Andreas Färber
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).

2013-06-28cpu: 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>
2013-03-03cpu: 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.
