This is only for the debug purpose. It is still unclear whether it can work on ICL. WhiskyLake BIOS will start APs and then each AP will call mwait to wait for BSP to write monitor memory location to wake them up. Currently the hypervisor will send SIPI to each AP and re-initialize them after the hypervisor boots up. So APs can't respond to the wakeup requests from BSP anymore. Fix: the hypervisor should send SIPI to the APs only after BIOS wakes up the AP. Signed-off-by: Jack Ren <jack.ren@intel.com> Signed-off-by: Zhao Yakui <yakui.zhao@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/
