[PATCH v2 5/7] HV: Use NMI-window exiting to address req missing issue
If the reason of NMI is not due to hypervisor related notification. There are no request bits set in pending request. So, we will do nothing in next nmi-window exiting. It is harmless except for extra

[PATCH v2 6/7] HV: Use NMI to replace INIT signal for lapic-pt VMs S5
We have implemented a new notification method using NMI. So replace the INIT notification method with the NMI one. Then we can remove INIT notification related code later. Signed-off-by: Kaige Fu <kai

[PATCH v2 3/7] HV: Use NMI to kick lapic-pt vCPU's thread
ACRN hypervisor needs to kick vCPU off VMX non-root mode to do some operations in hypervisor, such as interrupt/exception injection, EPT flush etc. For non lapic-pt vCPUs, we can use IPI to do so. But

[PATCH v2 1/7] HV: Push NMI vector on to the exception stack
This patch pushs the NMI vector (2) on to the exception stack. So, we can get the right vector in dispatch_exception. Signed-off-by: Kaige Fu <kaige.fu@...> --- hypervisor/arch/x86/idt.S | 6 +++
