IRTE is freed if ptirq entry is released from remove_msix_remapping() or remove_intx_remapping(). But if it's called from ptdev_release_all_entries(), e.g. SOS shutdown/reboot, IRTE is not freed. This patch adds a release_cb() callback function to do any architectural specific cleanup. In x86, it's used to release IRTE. On VM shutdown, vpci_cleanup() needs to remove MSI/MSI-X remapping on ptirq entries, thus it should be called before ptdev_release_all_entries().

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/
