1) The previous implementaion will recalculate the whole EOI-exit bitmap for each RTE once the destination, trigger mode, delivery mode or vector of a RTE has changed and update the EOI-exit bitmap for each vcpu of the VM. In this patch, only set the corresponding bit of EOI-exit bitmap for a vcpu when a level triggered interrupt has accepted in IRR or clear the corresponding bit of EOI-exit bitmap for a vcpu when a dege triggered interrupt has accepted in IRR which means only update a bit of EOI-exit bitmap in a vcpu when updating TMR. 2) Rename set eoi_exit related API to set eoi_exit_bitmap.

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/
