The Power State and Coordination Interface (PSCI) specification defines
SYSTEM_OFF and SYSTEM_RESET functions for system poweroff and reboot.
This patchset adds:
1. Emulation of PSCI SYSTEM_OFF and SYSTEM_RESET functions in
KVM ARM/ARM64 by forwarding them to user space (QEMU or KVMTOOL)
2. System poweroff and reboot using PSCI for ARM/ARM64 kernel
Anup Patel (5):
ARM/ARM64: KVM: Update user space API header for PSCI emulation
ARM/ARM64: KVM: Forward PSCI SYSTEM_OFF and SYSTEM_RESET to user
space
KVM: Add documentation for KVM_EXIT_PSCI exit reason
ARM: psci: Add support for system reboot and poweroff
ARM64: psci: Add support for system reboot and poweroff
