Subject: [PATCH v2 0/3] cpuidle: psci: Enable s2idle when using PSCI OSI
Date: Tue, 3 Nov 2020 16:06:24 +0100 [thread overview]
Message-ID: <20201103150627.233438-1-ulf.hansson@linaro.org> (raw)
Changes in v2:
- See changelog for each patch.
When using PSCI OSI together with the PM domain topology, the domain idle
states becomes selected via calls to pm_runtime_put_sync_suspend(). This works
fine for the regular idle path, but not for system wide suspend-to-idle.
This problem is because runtime PM gets disabled by the PM core, during system
wide suspend. In this small series, these issues are being fixed.
Kind regards
Ulf Hansson
