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: 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>
2014-02-04target-lm32: add breakpoint/watchpoint supportMichael Walle1-0/+1
This patch adds in-target breakpoint and watchpoint support. Signed-off-by: Michael Walle <michael@walle.cc>
2014-02-04target-lm32: move model features to LM32CPUMichael Walle1-1/+186
This allows us to completely remove CPULM32State from DisasContext. Instead, copy the fields we need to DisasContext. Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Michael Walle <michael@walle.cc>
2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-2/+4
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.

2013-07-27cpu: Introduce CPUClass::gdb_{read,write}_register()Andreas Färber1-0/+2
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>
2013-07-26cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regsAndreas Färber1-0/+1
CPUState::gdb_num_regs replaces num_g_regs. CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS. Allows building gdb_register_coprocessor() for xtensa, too. As a side effect this should fix coprocessor register numbering for SMP.

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>
2013-07-23cpu: Introduce CPUClass::set_pc() for gdb_set_cpu_pc()Andreas Färber1-0/+8
This moves setting the Program Counter from gdbstub into target code. Use vaddr type as upper-bound replacement for target_ulong. 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 Färber1-2/+0
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 Färber1-0/+1
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>
2013-03-18target-lm32: flush tlb after clearing envMichael Walle1-2/+2
The tlb data is stored within the CPU env. Therefore, the initialization has to be done after we clear the environment. Otherwise the tlb will have a valid entry for address 0x0. Signed-off-by: Michael Walle <michael@walle.cc>
2013-03-12target-lm32: Update VMStateDescription to LM32CPUAndreas Färber1-0/+1
Add a vmstate_lm32_cpu referencing the previous VMStateDescription as a sub-struct and hook it up to CPUClass::vmsd. Drop cpu_{save,load}(). Acked-by: Michael Walle <michael@walle.cc> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber1-0/+2
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>
2013-02-16cpu: 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.

Introduce a realizefn and set realized = true in cpu_lm32_init(). Also move cpu_reset() call from initfn to realizefn. Signed-off-by: Andreas Färber <afaerber@suse.de>
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().
