Yonghua Huang 0a7bb7340f hv: disable guest MONITOR-WAIT support when SW SRAM is configured ... Per-core software SRAM L2 cache may be flushed by 'mwait' extension instruction, which guest VM may execute to enter core deep sleep. Such kind of flushing is not expected when software SRAM is enabled for RTVM. Hypervisor disables MONITOR-WAIT support on both hypervisor and VMs sides to protect above software SRAM from being flushed. This patch disable ACRN guest MONITOR-WAIT support if software SRAM is configured.
