2017-06-28accel: introduce AccelClass.global_propsPeter Xu
Introduce this new field for the accelerator classes so that each specific accelerator in the future can register its own global properties to be used further by the system. It works just like how the old machine compatible properties do, but only tailored for accelerators. Introduce register_compat_props_array() for it. Export it so that it may be used in other codes as well in the future.

2017-06-27exec: allow to get a pointer for some mmio memory regionKONRAD Frederic
This introduces a special callback which allows to run code from some MMIO devices. SysBusDevice with a MemoryRegion which implements the request_ptr callback will be notified when the guest try to execute code from their offset. Then it will be able to eg: pre-load some code from an SPI device or ask a pointer from an external simulator, etc.. When the pointer or the data in it are no longer valid the device has to invalidate it. Reviewed-by: Edgar E.

2017-06-27cputlb: fix the way get_page_addr_code fills the tlbKONRAD Frederic
get_page_addr_code(..) does a cpu_ldub_code to fill the tlb: This can lead to some side effects if a device is mapped at this address. So this patch replaces the cpu_memory_ld by a tlb_fill.

2017-06-27cputlb: move get_page_addr_codeKONRAD Frederic
This just moves the code before VICTIM_TLB_HIT macro definition so we can use it. Reviewed-by: Richard Henderson <rth@twiddle.net> Reviewed-by: Edgar E.

2017-06-27cputlb: cleanup get_page_addr_code to use VICTIM_TLB_HITKONRAD Frederic
This replaces env1 and page_index variables by env and index so we can use VICTIM_TLB_HIT macro later. Reviewed-by: Richard Henderson <rth@twiddle.net> Reviewed-by: Edgar E.

2017-06-15accel: split the tcg accelerator from accel.c fileYang Zhong
there are some types of accelerators in qemu, and all accelerators have their own file except tcg. tcg accelerator is also defined in accel.c file. tcg accelerator file will be splited from accel.c and re-name to tcg-all.c. accel/ directory will be created to include kvm and tcg related files.
