From mboxrd@z Thu Jan 1 00:00:00 1970 From: broonie@opensource.wolfsonmicro.com (Mark Brown) Date: Mon, 26 Dec 2011 10:58:46 +0000 Subject: [PATCH] ARM: S3C64XX: Reduce residency requirement for cpuidle WFI mode Message-ID: <1324897126-8889-1-git-send-email-broonie@opensource.wolfsonmicro.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Entering and leaving WFI is really cheap so there's no reason to have much of a residency requirement for the state. Lower it to 1ms.
