2013-07-09cpu: Move reset logging to CPUStateAndreas Färber
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 Färber
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 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).

2013-07-09linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell
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 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: Pass CPUState to cpu_interrupt()Andreas Färber

2013-03-12exec: Pass CPUState to cpu_reset_interrupt()Andreas Färber
Move it to qom/cpu.c to avoid build failures depending on include order of cpu-qom.h and exec/cpu-all.h. Change opaques of various ..._irq_handler() functions to the appropriate CPU type to facilitate using cpu_reset_interrupt(). Fix Coding Style issues while at it (missing braces, indentation).

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

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.

2013-02-01target-m68k: 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 or -cpu ? output.

Consolidate model checking into a new m68k_cpu_class_by_name(). If the name matches an existing type, also check whether that type is (a sub-type of) TYPE_M68K_CPU. This fixes, e.g., -cpu ide-hd asserting. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber
