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 Färber2-3/+3
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).

2013-07-09linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell1-14/+0
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.

2013-04-08hw: move headers to include/Paolo Bonzini2-3/+3
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

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>

2013-03-18target-lm32: fix debug memory accessMichael Walle1-1/+6
CPU models which have the LM32_FLAG_IGNORE_MSB flag set will shadow the lower 2GB to the upper 2GB memory space. This will fix the debug memory access used by qemu console and GDB to match this behaviour. Signed-off-by: Michael Walle <michael@walle.cc>

2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber4-2/+8
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: Move halted and interrupt_request fields to CPUStateAndreas Färber2-4/+4
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 Maydell1-2/+2

2013-02-23qemu-log: Remove qemu_log_try_set_file() and its usersPeter Maydell1-2/+0
Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.

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.

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.
