2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber1-3/+2
Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Turn cpu_has_work() into a CPUClass hookAndreas Färber1-6/+0
Default to false. Tidy variable naming and inline cast uses while at it. Tested-by: Jia Liu <proljc@gmail.com> (or32) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-23cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()Andreas Färber1-5/+0
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 Maydell1-13/+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.

2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber1-1/+0
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 Färber1-3/+1
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>
2013-02-01target-unicore32: Mark as unmigratableAndreas Färber1-2/+0
CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a hw_error(). Therefore we can without problems suppress registration of "cpu_common" VMState by dropping CPU_SAVE_VERSION define and provide an unmigratable "cpu" VMStateDescription for UniCore32CPU at device level instead, where we can attach this the QOM way.

2012-10-31cpus: Pass CPUState to [qemu_]cpu_has_work()Andreas Färber1-1/+3
For target-mips also change the return type to bool. Make include paths for cpu-qom.h consistent for alpha and unicore32. Signed-off-by: Andreas Färber <afaerber@suse.de> [AF: Updated new target-openrisc function accordingly] Acked-by: Richard Henderson <rth@twiddle.net> (for alpha)
2012-08-11target-unicore32: Drop UC32_CPUID macrosAndreas Färber1-4/+0
Any code that depends on a particular CPU type can now go through callbacks on the QOM UniCore32CPUClass. Signed-off-by: Andreas Färber <afaerber@suse.de Acked-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-08-11unicore32-softmmu: Make UniCore32 cpuid & exceptions correct and runableGuan Xuetao1-6/+8
This patch initializes the cpuid to exactly correct value because linux kernel will check it. In addition, the exception types are specified in proper situations. Then it could make exceptions generated correctly and timely. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-03-30target-unicore32: QOM'ify CPUAndreas Färber1-0/+1
Embed CPUUniCore32State as first member of UniCore32CPU. Contributed under GPLv2+. Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: Guan Xuetao <gxt@mprc.pku.edu.cn>
2012-03-30target-unicore32: Relicense to GPLv2+Andreas Färber1-1/+2
Adopt the license text suggested by Guan Xue-tao (with a minor simplification) for all target-unicore/ files except helper.c. To helper.c Anthony Liguori contributed a qemu_malloc() -> g_malloc() conversion, still pending IBM relicensing approval, so that remains GPLv2 for now. By relicensing all possible parts now, we avoid having to formally relicense new, e.g., QOM code.
