With v3.16-rc4 the PM features for omap3 should be working
finally for device tree based booting. At lest beaglexm and
3xxevm should work.
Maybe you are using legacy booting path to idle the UARTs still?
FYI, I'm doing this to find the UART entries:
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode

Tony

OK thanks, I'll take a close look at it. It's not using the legacy paths,
but based on a glance at the 37xxevm logs, it looks like the bus address
of the UART isn't right.

Hmm for which UART? I'm using ttyO2 on my 37xxevm FYI, it can be selected
on the board based on some switch settings. I may have patched my u-boot
for that too but don't remember for sure.

Sorry, I should have been more specific. The path name that the script
here was using to write to the 'wakeup' file contained the base address.
It's probably just best to set them via /sys/class/tty as you do.

Just to follow up briefly on this: there was indeed a bug in the OMAP3
test scripts here that resulted in the UART wakeup not being enabled.
Once that was fixed, system suspend-based chip-retention and chip-off
modes work.
However, scheduler-idle based chip-retention and chip-off still are not
working. Looking at the logs, it appears that some domains are not
dynamically going idle. For example, looking at:
http://www.pwsan.com/omap/testlogs/test_v3.16-rc6/20140724142225/pm/37xxevm/37xxevm_log.txt
it can be seen that core_pwrdm's retention count doesn't increase between
the two PM debug dumps. The important lines are:
core_pwrdm (ON),OFF:0,RET:2,INA:0,ON:3,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
and
core_pwrdm (ON),OFF:0,RET:2,INA:0,ON:3,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
That's why the test reports mark the dynamic PM modes as failing.
...
Here's an example where things worked:
http://www.pwsan.com/omap/testlogs/test_v3.10/20130717134228/pm/3530es3beagle/3530es3beagle_log.txt
In this one, it can be seen that the CORE counts transitioned from:
core_pwrdm (ON),OFF:0,RET:2,INA:0,ON:3,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
to
core_pwrdm (ON),OFF:0,RET:10,INA:0,ON:11,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
between the retention suspend/resume test ending and the dynamic
retention idle test ending.

Hmm I think the difference with the working v3.10 one is that you have
root=/dev/mmcblk0p2 instead of root=/dev/nfs. As the Ethernet on beagle
is on the USB EHCI, this is still blocking the deeper idle states AFAIK.
Care to test -rc7 with root=/dev/mmcblk0p2 to see if that works?
On the am37xx-evm nfsroot will work as it's on the GPMC bus.

Hmm? There's no Ethernet on the 3530 Beagle.
The hardware configuration on those two boards - the 37xxevm and
the 3530es3beagle - hasn't changed between the two test runs, AFAIK.
Just to take the Beagle out of the equation, here's a test with the
37xxevm on 3.11 where it passes the dynamic idle tests:
http://www.pwsan.com/omap/testlogs/test_v3.11/20130902150604/pm/37xxevm/37xxevm_log.txt
And here's one on the 37xxevm on 3.16-rc7 where it fails:
http://www.pwsan.com/omap/testlogs/test_v3.11/20130902150604/pm/37xxevm/37xxevm_log.txt
I should probably read back those writes to autosuspend_delay_ms, just to
make sure they are reaching the right destinations. But you might want to
confirm that you can see the CORE RET count increasing during dynamic idle
on your 37xxevm.

the 3530es3beagle - hasn't changed between the two test runs, AFAIK.
Just to take the Beagle out of the equation, here's a test with the
37xxevm on 3.11 where it passes the dynamic idle tests:
http://www.pwsan.com/omap/testlogs/test_v3.11/20130902150604/pm/37xxevm/37xxevm_log.txt
And here's one on the 37xxevm on 3.16-rc7 where it fails:
http://www.pwsan.com/omap/testlogs/test_v3.11/20130902150604/pm/37xxevm/37xxevm_log.txt
I should probably read back those writes to autosuspend_delay_ms, just to
make sure they are reaching the right destinations. But you might want to
confirm that you can see the CORE RET count increasing during dynamic idle
on your 37xxevm.

Oh it's the original beagle, sorry. In that case the uart wake interrupts
need to be enabled for the serial wake to work. I did not do that as
I don't have one. I guess that might explain why it fails? Or are you
using RTC wake for your test?

Hmm seems to work on 37xxevm for me with my retention test script:
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
echo 0 > /sys/kernel/debug/pm_debug/enable_off_mode
Which produces:
core_pwrdm (ON),OFF:0,RET:7,INA:0,ON:8,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
And then setting enable_off_mode:
core_pwrdm (ON),OFF:15,RET:100,INA:8,ON:124,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0
And I'm using UART3 like I mentioned earlier, but I doubt that
makes a difference.
Are you maybe missing "echo auto > $uart/control"?

Just took a whack at that, looks like the autosuspend_delay_ms files are
being set correctly:
http://www.pwsan.com/omap/testlogs/test_v3.16-rc7/20140729023831/pm/37xxevm/37xxevm_log.txt
By the way, it's not obvious from the logs, but there's a 'sleep 5' on the
host between the autosuspend_delay_ms writes and the read of the
pm_debug/count file...

Serial wake works fine. But the chip never enters dynamic retention idle
as measured by the pm_debug/count differential for CORE powerdomain.
Works OK with static suspend.

It should be doing both of those things, according to the logs:
--------
# # for u in `ls -1d /sys/class/tty/ttyO* | paste -s -d' '`; do echo
enabled > $u/power/wakeup; done
#
%% Start retention double suspend/resume UART wakeup test
# for u in `ls -1d /sys/class/tty/ttyO* | paste -s -d' '`; do echo auto >
$u/power/control; done
--------
I will add code to read back the values from the sysfs files, just to make

Hmm maybe different u-boot version then? I'm using
2014.04-00001-g5f09f5b.

Using nfsroot and omap2plus_defconfig. My dmesg attached
in case it provides some clues. I don't have console=ttyO
here, but I've verified that it works with that too.

Walked through the PM test script by hand, and the proximal cause of the
problem became obvious...
Turns out a five-second delay for a three-second autosuspend_delay_ms is
no longer sufficient time for kernels to enter idle. A ten-second sleep
seems to be long enough.
Not sure what exactly is causing that weirdness yet, or when that started
happening. Am suspecting it could be some of the RCU changes over the
past couple of years. We don't have RCU_FAST_NO_HZ enabled in
omap2plus_defconfig; we should probably switch that on.
Now 37xxevm and the 3730beaglexm are entering idle as they should be.
Test report below; logs etc. have been uploaded. Thanks for the debug

Walked through the PM test script by hand, and the proximal cause of the
problem became obvious...
Turns out a five-second delay for a three-second autosuspend_delay_ms is
no longer sufficient time for kernels to enter idle. A ten-second sleep
seems to be long enough.
Not sure what exactly is causing that weirdness yet, or when that started
happening. Am suspecting it could be some of the RCU changes over the
past couple of years. We don't have RCU_FAST_NO_HZ enabled in
omap2plus_defconfig; we should probably switch that on.
Now 37xxevm and the 3730beaglexm are entering idle as they should be.
Test report below; logs etc. have been uploaded. Thanks for the debug
discussion,

3530es3beagle retention dynamic idle tests hang on next-20140729. (Maybe
other boards fail too - haven't tested any others).

Adding the patch you sent doesn't change that, but now some extra warning

I just checked that today's linux next works for off-idle and
wake-up events for at least 37xx evm.

Weird it should just work. I don't know why the "PRM: I/O chain
clock line assertion timed out" happens for you, I have not seen
that. So far I've tested it on n900, beagle xm and 37xx-evm. None
of those are 3530 though, but it should behave the same way as
on n900.

I just checked that today's linux next works for off-idle and
wake-up events for at least 37xx evm.

Weird it should just work. I don't know why the "PRM: I/O chain
clock line assertion timed out" happens for you, I have not seen
that. So far I've tested it on n900, beagle xm and 37xx-evm. None
of those are 3530 though, but it should behave the same way as
on n900.

The above patch works for me with ret/off-idle on beagle rev C4 on top
of 3.16-rc5. Without it, the board just seems to hang with ret, and with
off, it just doesn't respond to anything on uart but seems alive otherwise.

I ran the full set of tests across all boards. The only board that passed
the dynamic idle testing on next-20140729 was the 3730beaglexm.

37xxevm hangs on the first suspend entry:
http://www.pwsan.com/omap/testlogs/next_20140729/20140730124836/pm/37xxevm/37xxevm_log.txt
If I find some extra time, I'll set up a bisection run.

OK that sounds like some driver suspend regression that needs
to be tracked down. I'm seeing it on my 37xx evm also with
linux next too.

With no_console_suspend I'm seeing the following for smsc911x.
This does not happen with v3.16-rc, and there have been no changes
to smsc911x.c, so sounds like a good candidate for an automated
bisect and boot test.

With no_console_suspend I'm seeing the following for smsc911x.
This does not happen with v3.16-rc, and there have been no changes
to smsc911x.c, so sounds like a good candidate for an automated
bisect and boot test.

It's commit a71e3c37960ce5f9c6a519bc1215e3ba9fa83e75:

net: phy: Set the driver when registering an MDIO bus device
mdiobus_register() registers a device which is already bound to a driver.
Hence, the driver pointer should be set properly in order to track down
the driver associated to the MDIO bus.
This will be used to allow ethernet driver to pin down a MDIO bus driver,
preventing it from being unloaded while the PHY device is running.

What's bad is that this went in late during v3.16-rc fixes. So now v3.16
itself is broken, and there's no way to fix it.
As far as I can tell, this patch doesn't fix a regression. So no way it
should have gone in during late -rc kernels.

I have sent a patch reverting this commit and it is in mainline now.
It will reach 3.16.1:
commit ce7991e8198b80eb6b4441b6f6114bea4a665d66

Revert "net: phy: Set the driver when registering an MDIO bus device"
Commit a71e3c37960ce5f9 ("net: phy: Set the driver when
registering an MDIO bus
device") caused the following regression on the fec driver:

The problem with the original commit is explained by Russell King:
"It has the effect (as can be seen from the oops) of attaching the MDIO bus
device (itself is a bus-less device) to the platform driver, which means
that if the platform driver supports power management, it will be called
to power manage the MDIO bus device.
Moreover, drivers do not expect to be called for power management
operations for devices which they haven't probed, and certainly not for
devices which aren't part of the same bus that the driver is registered
against."
This reverts commit a71e3c37960ce5f9c6a519bc1215e3ba9fa83e75.

of course not, but your claim that there's no way to fix v3.16 is
nonsense. And mistakes occur as well.

There is no way to fix v3.16.
The point of the -rc cycle is to stabilize the final, non-rc releases.

There is no way to fix *any* commit.
We can go back a few major releases and we will hit a point when ARM
multiplatform was enabled and the tree doesn't even build. There is no
way to fix that either, but I'm sure the patches fixing the build breaks
have been back ported to stable.

Well, stable release are *not* -rc releases and they exist in order to
fix bugs that were found after the final release has been tagged;
otherwise what would be the point of even having -stable ?

Indeed, the commit shouldn't have landed as a v3.16-rc fix. FWIW, it was
originally intended for v3.17, but I wasn't clear enough about this when it
was submitted.
