List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Hi all, Yeah, I know reading the code should be the answer... But anyone would like give me an overview on how IO emulation is done in QEMU, so that I can have a start point to dig it out myself? I like to know how much time QEMU spend on IO emulation, so I have to know where/what function should I start counting. Thanks.
