Subject: [Qemu-devel] [PATCH v8 07/21] hw/virtio: Access MemoryRegion with MemOp
Date: Thu, 22 Aug 2019 01:09:01 +1000 [thread overview]
Message-ID: <4f59237776f5ea9d42f144400b8e75c040e9e906.1566397711.git.tony.nguyen.git@gmail.com> (raw)
In-Reply-To: <cover.1566397711.git.tony.nguyen.git@gmail.com>
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.
