In this case, we could handle all the passthrough PCI devices in ACRN hypervisor. But we still need DM to initialize BAR resources and Intx for passthrough PCI device for post-launched VM since these informations should been filled into ACPI tables. So 1. we add a HC vm_assign_pcidev to pass the extra informations to replace the old vm_assign_ptdev. 2. we saso remove HC vm_set_ptdev_msix_info since it could been setted by the post-launched VM now same as SOS. 3. remove vm_map_ptdev_mmio call for PTDev in DM since ACRN hypervisor will handle these BAR access. 4. the most important thing is to trap PCI configure space access for PTDev in HV for post-launched VM and bypass the virtual PCI device configure space access to DM. This patch doesn't do the clean work. Will do it in the next patch. Tracked-On: #4371 Signed-off-by: Li Fei1 <fei1.li@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/
