2013-07-23cpu: Introduce CPUClass::memory_rw_debug() for target_memory_rw_debug()Andreas Färber
Make inline target_memory_rw_debug() always available and change its argument to CPUState. Let it check if CPUClass::memory_rw_debug provides a specialized callback and fall back to cpu_memory_rw_debug() otherwise. The only overriding implementation is for 32-bit sparc. This prepares for changing GDBState::g_cpu to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-23cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()Andreas Färber
Where no extra implementation is needed, fall back to CPUClass::set_pc(). Acked-by: Michael Walle <michael@walle.cc> (for lm32) Signed-off-by: Andreas Färber <afaerber@suse.de>
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.

2013-06-28cpu: Turn cpu_unassigned_access() into a CPUState hookAndreas Färber
Use it for all targets, but be careful not to pass invalid CPUState. cpu_single_env can be NULL, e.g. on Xen. Signed-off-by: Andreas Färber <afaerber@suse.de>
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: 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>

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr.

2012-04-07target-sparc: QOM'ify CPUAndreas Färber
Embed CPUSPARCState as first member of SPARCCPU. Drop cpu_sparc_close() in favor of object_delete() and a finalizer. Let cpu_state_reset() call cpu_reset(). Make TYPE_SPARC_CPU non-abstract for now.

2011-09-10Gdbstub: Fix back-trace on SPARC32Fabien Chouteau
Gdb expects all registers windows to be flushed in ram, which is not the case in Qemu. Therefore the back-trace generation doesn't work.

2011-07-21SPARC64: implement addtional MMU faults related to nonfaulting loadTsuneo Saito
This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.

This patch makes cpu_get_phys_page_debug() independent from cpu_get_phys_page_nofault() in advance of implementing nonfaulting load. This also modifies cpu_get_phys_page_nofault() to be compiled only on TARGET_SPARC64 because it is not required on SPARC32.
