When shutting down SOS VM, the shared sbuf is released from guest OS, but the per cpu sbuf pointers in hypervisor keep inact. This creates a problem that after SOS is re-launched, hypervisor could write to the shared buffer that no longer exists. This patch implements sbuf_reset() and call it from reset_vcpu() to reset sbuf pointers. Tracked-On: #2700 Signed-off-by: Zide Chen <zide.chen@intel.com> Acked-by: Anthony Xu <anthony.xu@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/
