2013-09-02tcg: Change tcg_gen_exit_tb argument to uintptr_tRichard Henderson1-1/+1

2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-1/+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.

Replace the GDB_CORE_XML define in gdbstub.c with a CPUClass field. Use first_cpu for qSupported and qXfer:features:read: for now. Add a stub for xml_builtin. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-27cpu: Introduce CPUClass::gdb_{read,write}_register()Andreas Färber4-2/+15
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>
2013-07-27gdbstub: Replace GET_REG*() macros with gdb_get_reg*() functionsAndreas Färber1-4/+4
This avoids polluting the global namespace with a non-prefixed macro and makes it obvious in the call sites that we return. Semi-automatic conversion using, e.g., sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c followed by manual tweaking for sparc's GET_REGA() and Coding Style.

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.

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().

2013-07-23gdbstub: Change syscall callback argument to CPUStateAndreas Färber1-1/+4
Callback implementations were specific to arm and m68k, so can easily cast to ARMCPU and M68kCPU respectively. Prepares for changing GDBState::c_cpu to CPUState. 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.

2013-07-09cpu: 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).

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 Färber4-3/+11

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-m68k: Rename CPU subtypesAndreas Färber2-5/+14
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 or -cpu ? output.
