If the community is interested, I would like to discuss the Generic Asynchronous task offloading framework patches posted to the community on 24th May 2010. URL:http://lists.gnu.org/archive/html/qemu-devel/2010-05/msg02227.html Brief Description: The patch series extracts out the task offloading framework code from posix-aio-compat.c which is currently being used only by the paio subsystem to create a generic task offloading framework that could be used by other subsystems within qemu. Currently virtio-9p and asynchronous-encoding from vnc server can make use of the generic framework. Points for discussion: - Is a generic task offloading framework the way to go for subsystems such as virtio-9p, which would like to emulate the AIO behaviour that allows us to free the vcpu thread to handle any other guest requests. - Currently the AIO helper threads indicate the completion of the task to the IO-thread by sending a SIGUSR2, the handler for which does a write() to the file descriptor on which the IO thread is waiting using a select. Should we use this signal-handling mechanism to communicate between the generic asynchronous helper threads and the IO-Thread ? > If we have a lack of agenda items I'll cancel the week's call. > > thanks, > -chris > -- Thanks and Regards gautham -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
