[Qemu-devel] [PATCH v8 07/21] hw/virtio: Access MemoryRegion with MemOp |
Date: |
Thu, 22 Aug 2019 01:09:01 +1000 |
The memory_region_dispatch_{read|write} operand "unsigned size" is
being converted into a "MemOp op".
Convert interfaces by using no-op size_memop.
After all interfaces are converted, size_memop will be implemented
and the memory_region_dispatch_{read|write} operand "unsigned size"
will be converted into a "MemOp op".
As size_memop is a no-op, this patch does not change any behaviour.
