This patch can fetch the thermal lvt irq and propagate it to VM. At this stage we support the case that there is only one VM governing thermal. And we pass the hardware thermal irq to this VM. First, we register the handler for thermal lvt interrupt, its irq vector is THERMAL_VECTOR and the handler is thermal_irq_handler(). Then, when a thermal irq occurs, it flags the SOFTIRQ_THERMAL bit of softirq_pending, This bit triggers the thermal_softirq() function. And this function will inject the virtual thermal irq to VM.

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/
