[Qemu-devel] [PATCH 0/5] ARM: add PSCI 0.2 support in TCG mode

[Ard Biesheuvel]

This series adds PSCI support to ARM and AArch64 system emulation when running
in TCG mode. As PSCI calls can be made using either hypervisor call (HVC) or
secure monitor call (SMC) instructions, support is added for handling those
in patch #3 before patch #4 adds the actual PSCI dispatch logic. Patch #5
enables PSCI for the mach-virt platform.

Currently, booting multiple cores under TCG is unstable, so the restriction
to 1 cpu in TCG mode is retained for now. However, PSCI reset and poweroff are
supported.

Rob Herring (5):
  target-arm: add powered off cpu state
  target-arm: support AArch64 for arm_cpu_set_pc
  target-arm: add hvc and smc exception emulation handling
    infrastructure
  target-arm: add emulation of PSCI calls for system emulation
  arm/virt: enable PSCI emulation support for system emulation
