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@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
