Now we do not need pending_pre_work anymore, as we can make sure IO request VCPU resume from where it paused. Now only three fixed points will try to do schedule: - vcpu_thread: before vm entry, will check reschedule flag and to it if needed - default_idle: loop check reschedule flag to see if need switch out - io request: if IO REQ need DM's handle, it will schedule out Tracked-On: #2394 Signed-off-by: Jason Chen CJ <jason.cj.chen@intel.com> Acked-by: Xu, Anthony <anthony.xu@intel.com>
ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the “ACRN Device Model”. The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
