Currently host bridge emulation and bar emulation are only for pre-launched vms, use is_prelaunched_vm to check if it is for pre-launched vms when calling init/deinit/cfgread/cfgwrite, also use is_hostbridge() to check if the access if for host bridge, so that these functions can be unified for sos and pre-launched vm in subsequent commits. Move is_hostbridge function to vpci_priv.h so that it can be used by multiple files. vhostbridge_cfgread/vhostbridge_cfgwrite: return -ENODEV if the pci cfg access is not targeted for vhostbridge so that cfgread/cfgwrite functions can be unified for sos and pre-launched vm in subsequent commits Fix @pre for functions Tracked-On: #3056 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Reviewed-by: Eddie Dong <eddie.dong@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/
