2013-12-02misc: Replace 'struct QEMUTimer' by 'QEMUTimer'Stefan Weil
Most code already used QEMUTimer without the redundant 'struct' keyword. Signed-off-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2013-11-20openrisc-timer: Reduce overhead, Separate clock update functionsSebastian Macke
The clock value is only evaluated when really necessary reducing the overhead of the timer handling. This also solves a problem in the way the Linux kernel handles the timer and the expected accuracy. The old version could lead to inaccurate timings.

2013-07-27cpu: Introduce CPUClass::gdb_{read,write}_register()Andreas Färber
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>
2013-07-23cpu: Turn cpu_get_phys_page_debug() into a CPUClass hookAndreas Färber
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::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>
2013-07-09cpu: 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.

2013-06-28cpu: Turn cpu_dump_{state,statistics}() into CPUState hooksAndreas Färber
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>
2013-06-28target-openrisc: Register VMStateDescription for OpenRISCCPUAndreas Färber
Since commit e67db06e9f6d7e514ee2a9b9b769ecd42977f6fb (target-or32: Add target stubs and QOM cpu) a VMStateDescription existed, but CPU_SAVE_VERSION was not set, so it was never registered. Drop cpu_{save,load}() and register VMStateDescription via DeviceState. Use a version_id of 1 and specify minimum versions as well.

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>
2013-03-03cpu: Introduce ENV_OFFSET macrosAndreas Färber
Introduce ENV_OFFSET macros which can be used in non-target-specific code that needs to generate TCG instructions which reference CPUState fields given the cpu_env register that TCG targets set up with a pointer to the CPUArchState struct.

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.
