Re: [Qemu-devel] [PATCH] qmp: extend QMP to provide read/write access to physical memory

[Bryan D. Payne]

It is critical as a transport data structure. You have to define a byte-by-byte

layout (concerning endianness and padding) and use padding fields together with
QEMU_PACKED, so the representation is not dependent on alignment

This makes sense for network protocols.  But, in this case, the protocol is always taking placing over a unix socket on the localhost.  This is why I wasn't sure that it was necessary.

Just to be clear... the QMP connection could go over the network, but its only purpose is to set up the unix socket on the local machine (meaning that doing it over the network is kind of pointless, even if it is possible).  Once the unix socket is setup, the memory access protocol happens over that socket.

Thoughts?
