Subject: Re: [PATCH RFC v3 4/6] arm64: add PSCI CPU_SUSPEND based cpu_suspend support
Date: Fri, 09 May 2014 16:11:23 -0700 [thread overview]
Message-ID: <536d609c.0458440a.0ea9.77a3@mx.google.com> (raw)

Quoting Lorenzo Pieralisi (2014-05-06 11:04:41)
> This patch implements the cpu_suspend cpu operations method through
> the PSCI CPU_SUSPEND API. The PSCI implementation translates the idle state
> index passed by the cpu_suspend core call into a valid PSCI state according to
> the PSCI states initialized at boot by the PSCI suspend backend.
>
> Entry point is set to cpu_resume physical address, that represents the
> default kernel execution address following a CPU reset.
>
> Idle state indices missing a DT node description are initialized to power
> state standby WFI so that if called by the idle driver they provide the
> default behaviour.
