2014-03-13cputlb: Change tlb_flush() argument to CPUStateAndreas Färber1-1/+1
Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber1-1/+1
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber1-1/+3
Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Factor out cpu_generic_init()Andreas Färber1-12/+1
All targets using it gain the ability to set -cpu name,key=value,... options via the default TYPE_CPU CPUClass::parse_features() implementation. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Turn cpu_has_work() into a CPUClass hookAndreas Färber1-0/+6
Default to false. Tidy variable naming and inline cast uses while at it. Tested-by: Jia Liu <proljc@gmail.com> (or32) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-10-07cpu: Drop cpu_model_str from CPU_COMMONAndreas Färber1-1/+0
Since this is only read in cpu_copy() and linux-user has a global cpu_model, drop the field from generic code. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-2/+3
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 Färber1-1/+4
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>
2013-07-23target-moxie: Implement CPUClass::set_pc()Andreas Färber1-0/+8
This adds support for GDB's c addr (Continue) and s addr (Single Step). Prepares for dropping cpu_pc_from_tb(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-09cpu: Move reset logging to CPUStateAndreas Färber1-5/+0
x86 was using additional CPU_DUMP_* flags, so make that configurable in CPUClass::reset_dump_flags. This adds reset logging for alpha, unicore32 and xtensa.

2013-07-09log: Change log_cpu_state[_mask]() argument to CPUStateAndreas Färber1-1/+1
Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no longer needed. Add documentation and make the functions available through qemu/log.h outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h was not yet possible due to convoluted include paths, so that some devices grow an implicit and unneeded dependency on qom/cpu.h for now.

2013-06-28cpu: Change qemu_init_vcpu() argument to CPUStateAndreas Färber1-3/+2
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 Färber1-1/+2
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>
2013-04-12target-moxie: Fix VMState registrationPeter Maydell1-1/+1
Register the CPU VMState in the correct way, via cpu_class_set_vmsd(), rather than doing it in two different wrong ways (once by providing cpu_save and cpu_load functions, and once by setting the vmsd field in DeviceClass).
