I did some testing today on my 3.0GP 3430SDP. This is with the omap_3430sdp_min_defconfig. 1) Idle. echo -n 1 > /sys/power/clocks_off_while_idle echo -n 1 > /sys/power/enable_off Could not hit RET. something seems to be still active. Not sure if it could be something to do with this error that's thrown while bootup <6>Disabling unused clock "dpll5_ck" Disabling unused clock "dpll5_ck" <3>clock: dpll5_ck failed transition to 'locked' clock: dpll5_ck failed transition to 'locked' Further doing a echo -n 1 > /sys/power/sleep_while_idle causes a hang after the 5 odd secs of UART inactivity. Is'nt this option supposed to affect only the suspend path behavior? Is CPUidle disabled in the default defconfig now? 2) Suspend echo -n 1 > /sys/power/clocks_off_while_idle Hangs on a echo mem > /sys/power/state Goes into suspend, but cannot recover 3) DVFS Both VDD1 and VDD2 DVFS seem to function fine. > -----Original Message----- > From: linux-omap-owner@xxxxxxxxxxxxxxx > [mailto:linux-omap-owner@xxxxxxxxxxxxxxx] On Behalf Of Kevin Hilman > Sent: Wednesday, January 14, 2009 3:22 AM > To: linux-omap@xxxxxxxxxxxxxxx > Subject: new PM branch available > > Hello, > > The latest PM branch is now available[1]. > > I've done basic testing of retention and off-mode (suspend and dynamic > idle) on Beagle and custom HW.
