Subject: [kvm-unit-tests PATCH v3 05/18] lib: arm/arm64: Remove unused CPU_OFF parameter
Date: Tue, 31 Dec 2019 16:09:36 +0000	[thread overview]
Message-ID: <1577808589-31892-6-git-send-email-alexandru.elisei@arm.com> (raw)
In-Reply-To: <1577808589-31892-1-git-send-email-alexandru.elisei@arm.com>

The first version of PSCI required an argument for CPU_OFF, the power_state
argument, which was removed in version 0.2 of the specification [1].
kvm-unit-tests supports PSCI 0.2, and KVM ignores any CPU_OFF parameters,
so let's remove the PSCI_POWER_STATE_TYPE_POWER_DOWN parameter.

[1] ARM DEN 0022D, section 7.3.
