VDD1 : 2.0 mA VDD2 : 2.3 mA The numbers are on the higher side as the thresholds are still not optimal. Currently C6 has a threshold set to 300 ms which seems to be very low. We are working on deriving the optimal thresholds for each C state. > -----Original Message----- > From: linux-omap-owner@vger.kernel.org > [mailto:linux-omap-owner@vger.kernel.org] On Behalf Of Rajendra Nayak > Sent: Tuesday, July 01, 2008 7:46 PM > To: linux-omap@vger.kernel.org > Subject: [PATCH 00/11] OMAP3 CPUidle patches > > Hi, > > The following patches define and enable all of the below > mentioned C states for OMAP3. > These are tested with a minimal kernel config on OMAP3430sdp > as most drivers today don't have context save/restore in place and > some even lack aggresive clock handling. > These apply on top of the workaround patch set submitted by Jouni. > ([PATCH 0/6] 34XX: PM: Workarounds to get omap3 to retention 4th.) > > The following is neccessay even with a minimal config to achieve OFF. > $ echo 1 > /sys/power/sleep_while_idle > $ echo 1 > /sys/power/clocks_off_while_idle > > The following C states are defined > C0 - System executing code > C1 - MPU WFI + Core active > C2 - MPU CSWR + Core active > C3 - MPU OFF + Core active > C4 - MPU CSWR + Core CSWR > C5 - MPU OFF + Core CSWR > C6 - MPU OFF + Core OFF > > regards, > Rajendra > > > > -- > To unsubscribe from this list: send the line "unsubscribe > linux-omap" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
