List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Gerd Hoffmann , qemu-devel I took a quick look at the MTP emulation and the first things I noticed are: * all I/O is synchronous >> I guess this is just a limitation of the code * it doesn't use the -fsdev infrastructure >> Perhaps we should rename the "root" property to x-root to identify it as experimental? * it doesn't do writes >> No idea if this is a limitation of the protocol Anything we can do before 2.1 is out?
