Subject: [kvm-unit-tests PATCH v2 05/18] lib: arm/arm64: Remove unused CPU_OFF parameter
Date: Thu, 28 Nov 2019 18:04:05 +0000 [thread overview]
Message-ID: <20191128180418.6938-6-alexandru.elisei@arm.com> (raw)
In-Reply-To: <20191128180418.6938-1-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.
