2016-05-19cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini
exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19target-unicore32: make cpu-qom.h not target specificPaolo Bonzini
Make UniCore32CPU an opaque type within cpu-qom.h, and move all definitions of private methods, as well as all type definitions that require knowledge of the layout to cpu.h. This helps making files independent of NEED_CPU_H if they only need to pass around CPU pointers. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-12tb: consistently use uint32_t for tb->flagsEmilio G. Cota
We are inconsistent with the type of tb->flags: usage varies loosely between int and uint64_t. Settle to uint32_t everywhere, which is superior to both: at least one target (aarch64) uses the most significant bit in the u32, and uint64_t is wasteful. Compile-tested for all targets.

2015-09-25unicore: Remove ELF_MACHINE from cpu.hPeter Crosthwaite
The only generic code relying on this is linux-user, but linux users' default behaviour of defaulting ELF_MACHINE to ELF_ARCH will handle this. This removes another architecture specific definition from the global namespace.

2015-09-11tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt
This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.

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: Move halted and interrupt_request fields to CPUStateAndreas Färber

2013-02-01target-unicore32: Mark as unmigratableAndreas Färber
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.
