Subject: [PATCH v11 12/12] ARM/ARM64: KVM: Advertise KVM_CAP_ARM_PSCI_0_2 to user space
Date: Tue, 29 Apr 2014 11:24:25 +0530 [thread overview]
Message-ID: <1398750865-10892-13-git-send-email-anup.patel@linaro.org> (raw)
In-Reply-To: <1398750865-10892-1-git-send-email-anup.patel@linaro.org>
We have PSCI v0.2 emulation available in KVM ARM/ARM64
hence advertise this to user space (i.e. QEMU or KVMTOOL)
via KVM_CHECK_EXTENSION ioctl.
