From mboxrd@z Thu Jan 1 00:00:00 1970 From: anup.patel@linaro.org (Anup Patel) Date: Mon, 25 Nov 2013 21:19:57 +0530 Subject: [PATCH 0/2] PSCI system off and reset for KVM ARM/ARM64 Message-ID: <1385394599-15439-1-git-send-email-anup.patel@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The Power State and Coordination Interface (PSCI) specification defines SYSTEM_OFF and SYSTEM_RESET functions for system poweroff and reboot. This patchset adds emulation of PSCI SYSTEM_OFF and SYSTEM_RESET functions in KVM ARM/ARM64 by forwarding them to user space (QEMU or KVMTOOL) using KVM_EXIT_SHUTDOWN and KVM_EXIT_RESET exit reasons. To try this patch from guest kernel, we will need PSCI-based restart and poweroff support in the guest kenel for both ARM and ARM64. Rob Herring has already submitted patches for PSCI-based restart and poweroff in ARM kernel but these are not merged yet due unstable device tree bindings of kernel PSCI support. We will be having similar patches for PSCI-based restart and poweroff in ARM64 kernel.
