2018-10-15 Thread Heinrich Schuchardt
When an operating system started via bootefi tries to reset or power off this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or a
