PM branch rebased to 2.6.29

PM branch rebased to 2.6.29

[Kevin Hilman]

FYI... 

The PM branch has now been rebased to today's linux-omap HEAD which is
based on v2.6.29-rc8.  The previous PM branch has been renamed to
pm-2.6.28.  Depending on when you look, Tony's linux-omap tree may not
(yet) have the latest PM branch.  If not, you can use my PM tree[1]
directly.  Also, pm-2.6.28 will only be available on my tree.

Tested on OMAP3 Beagle and RX51 and was able to hit RET and OFF in
suspend and in PM idle with minimal kernel.  No testing yet done for
CPUidle or DVFS.  Please test on your hardware and submit results to
the list.  Thanks.

Kevin

Misc. conflicts/issues resolved after rebase:

- no longer safe to use getnstimeofday() in suspend path since timekeeping
  subsystem is also suspended in the suspend path.  PM debug timing has
  been converted to use sched_clock() which is 32k sync-timer based.

- Update board-rx51.c to use common OMAP3 OPPs

Known issues:

- Beagle: MMC: off-mode needs work in MMC driver, so if you hit off
  and have a rootfs on MMC, you're dead.

- Beagle: MMC regulator: unbalanced disables.  This happens on boot
  and during suspend/resume. I don't think this is related to the PM
  branch, but is probably in linux-omap HEAD also, but didn't test.

Sorry for ignorance, but in your PM tree the latest stuff is in
the pm branch, right?

Yes.  The master branch of my tree just tracks linux-omap.

It is.  Other boards may see that too.  Two fixes:

 * Least hassle ... I think all these should merge to the
   linux-omap tree in any case (and thence linux-pm):

    http://marc.info/?l=linux-omap&m=123699264117846&w=2
    http://marc.info/?l=linux-omap&m=123699340818395&w=2
    http://marc.info/?l=linux-omap&m=123705919713239&w=2

 * Or there are a number of regulator-framework patches
   floating around, all of which fix the bug there...

The root cause of this is that u-boot leaves VMMC1 active,
and the regulator framework doesn't cope with that yet.
The stackdump is basically caused by self-inconsistencies
in that framework.

The first fix lets the twl4030-power driver (not yet on
track for mainline merge) undo that, so the regulator
framework will no longer be confused.  That presumes a
bunch of board-specific patches fix that issue.  (As
well as setting up other power resources, e.g. so that
CLKREQ behaves, which is the real goal of that patch.)

The second fix -- in some flavor -- is IMO still needed,
since the first fix is just avoiding regulator framework
bugs.

Pushed these. That way we'll end up with a working
2.6.29-omap1 :)

Dave, got a version of the third patch above against the
mainline kernel? That could be added to the omap3-boards
queue for the upcoming merge window.

To me it sounds like the regulator framework should eventually
handle the regulators left on by the bootloader. Just let me
know if some other patches are needed to l-o tree meanwhile.

I approve that message.  ;)

That patch was a bit messy ... combined the VPLL2 bits,
and the twl4030-power bits.  The former can go to mainline,
but only after the regulator framework updates for VPLL2;
I'll make such a patch.  The latter needs twl4030-power to
get to mainline ...

I may just prepare an mmc-twl4030 patch with ugly workarounds,
since I'm getting the strong feeling that it'll take forever
to get the regulator framework fixed in that area.

Meanwhile, I suggest merging the updated version of the Overo
patch, as sent by Steve.

That should be now applied, looks like the MMC is still not
working though.

Heh, user error.. I was missing CONFIG_REGULATOR in my .config.
Works now.

Kevin,  did you build/test with
the /arc/arm/config/omap3_beagle_defconfig, and
arc/arm/configs/rx51_defconfig or some other config(could you send it to
me if it isn't in the PM tree)?  I'm trying to bring up your PM branch
on my OMAP3530_LV_SOM, using LDP as a starting point, and it goes into
retention but doesn't come back out, and rather than thrash on the LDP
defconfig, start with a config/code that is known to work.  I'm also
resnapping to commit c3127068... to jump to the latest from your tree
and start my port over.  I have to get suspend/resume working first
before I start working in all the drivers, and check that suspend/resume
works for each functional addition...

Thanks in advance!

I started with the ones in the tree, but I disable most of the drivers
and turn on some debugging features.  Attached is the one I used for
beagle.

Hmm, I modified your config to add smc911x support so I can have an
nfsroot, added selector/code for my board(based on omap3beagle.c) and
brought it up on my hardware, but I'm not sure if its working correctly.
It does look to pause in the suspend sate, and comes out when I hit a
key on the console, but the messages don't look quite right as
core_pwrdm and per_pwrdm state they didn't go into state 1 (full log
attached):

omap3530# echo mem > /sys/power/state
PM: Syncing filesystems ... done.
PM: Preparing system for mem sleep
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
PM: Entering mem sleep
Powerdomain (core_pwrdm) didn't enter target state 1
Powerdomain (per_pwrdm) didn't enter target state 1
Could not enter target state in pm_suspend
eth0: smc911x_reset timeout waiting for PM restore

eth0: link down
PM: Finishing wakeup.
Restarting tasks ... done.
omap3530# 
omap3530# eth0: link up, 100Mbps, full-duplex, lpa 0x45E1


Is this expected?

Yes, you haven't allowed the UART clocks to go off during idle/suspend 
and there are UARTs in both CORE and PER.

Try this before going into suspend:

   echo 1 > /sys/power/clocks_off_while_idle

This will allow UART clocks to be disabled on suspend, and also allow 
them to be disabled after 5 seconds of UART inactivity allowing 
retention in idle as well.

that Fixed PER, but CORE still says it couldn't go into state 1:

omap3530# echo 1 > /sys/power/clocks_off_while_idle
omap3530# echo mem > /sys/power/state
PM: Syncing filesystems ... done.
PM: Preparing system for mem sleep
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
PM: Entering mem sleep
Powerdomain (core_pwrdm) didn't enter target state 1
Could not enter target state in pm_suspend
eth0: smc911x_reset timeout waiting for PM restore
eth0: link down
PM: Finishing wakeup.
Restarting tasks ... done.

Re: PM branch rebased to 2.6.29

[Jean Pihet]

Hi,

I am having a crash with the latest 2.6.29 pm branch with CPU_FREQ enabled. It 
looks like clk_set_rate is called recursively, thus deadlocking on the mutex.

Any idea why this worked fine on 2.6.29-rc8 pm?

Here is the dump excerpt:

I'm having the same problem, and setting clocks_off_while_idle doesn't
help. I was initially suspicious that the bits in PM_WKEN1_CORE and
PM_WKEN3_CORE needed to be cleared (for core), but using devmem2 to
clear them didn't help.

For the purposes that I'm using my board for, I need to get everything
into the lowest power consumption possible while sleeping. eg,
everything in off mode but the WKUP domain.

I had found that two drivers that could prevent clocks_off are
USB and DSS because of the way they use clk_enable().

Can you try building without theses drivers just for verification?

How does DSS2 behave in that regard, and is there any effort in fixing  
the MUSB and EHCI drivers?

The problem has already been fixed in DSS2. Vaibhav had discussed it
a few weeks back on the list.

I am aware of the effory for USB, EHCI effort... but not the timelines.

Building without dss makes things worse:

Powerdomain (dss_pwrdm) didn't enter target state 0

Maybe by looking at what the dss driver is doing I can get core and
per to turn off.

Peter,

Have you tried with the debug patch I sent?  If you can test with that
patch, and send the output, I can tell you what is preventing you from
hitting RET.

FWIW, the latest HEAD of the PM branch has that debug patch included.

After doing the suspend/resume, just

# cat /debug/pm_debug/registers/1

and attach the output.

Kevin

No, not yet.  After comments by Kevin and others regarding my DPLL
setting being wrong from u-boot, I'm currently trying to bring up u-boot
from the Beagle on the LV SOM.  Then I can get the timings for the SDRC
correct, and then work on getting the lates PM rebase (2.6.29) to boot.
When I tried it with my current u-boot (based on 1.1.4 labrador), it
would sporadically hang in rtc_hctosys and other functions that tried to
talk to the twl4030 via i2c...

I'm running into problems with u-boot (cloned the Beagle config) where
I2C to setup power domains fails after the first write (bus gets stuck
busy).

Russ,

Can you try with the latest HEAD of PM branch.  After suspend/resume,
do

# cat /debug/pm_debug/registers/1

and post results to list.  We can then see the exact state of PM
registers before going into WFI.

Also, post dump of

# cat /debug/pm_debug/count

Thanks,

Kevin

Re: PM branch rebased to 2.6.29

[Russ Dill]

BTW, the 9 clocks active on per are:

gpio{2-6}_ick
per_l4_ick
uart3_ick
uart3_fck
per_48m_fck

During sleep, I get (for the per_clkdm only):

clockdomain: clkdm per_clkdm: removing clk uart3_ick
clockdomain: clkdm per_clkdm: removing clk per_48m_fck
clockdomain: clkdm per_clkdm: removing clk uart3_fck
clockdomain: clkdm per_clkdm: adding clk uart3_ick
clockdomain: clkdm per_clkdm: adding clk uart3_fck
clockdomain: clkdm per_clkdm: adding clk per_48m_fck

So it looks like to me that the per_clkdm isn't shutting down because
of per_l4_ick and the gpio interface clocks.

Russ,

With the dump below, what was the output after you resumed?  Which
powerdomains did not hit their target state?  It looks like PER and
CORE did not hit target state.

Also, you didn't mention what hardware you're using or your .config or
your bootloader etc.  All of these play an important role.

Here is at least one problem.

Offset 0x40 is CM_CLKSEL_WKUP, and bit 0 shows which clock is the
source clock for GPTIMER1.  Here, bit 0 is 1 which means SYS_CLK
is used as the timer source.  

Based on this, you must have:

   System Type --> TI OMAP Implementations --> System Timer

set to 'MPU timer'.  Please change to 32k timer.  Using MPU timer will
keep timers not in WKUP powerdomain (which is all of them except GPT1)
running across suspend, preventing PER from hitting RET.

Using the 32k timer only uses GPT1 and sources it from the 32k clock, both
of which are in the WKUP powerdomain.

Based on this, I see that you're DSS is not the problem anymore as it
is hitting off, but neither PER nor CORE have made any transistions.
PER is most likely because of the timer issue above.  Not sure yet
about CORE.

In addtion to more details on your hardware and .config, Can you send
me the console log of a full boot followed by trying just retention in
suspend by doing the following right after boot:

# cat /debug/pm_debug/count
# echo 1 > /sys/power/clocks_off_while_idle
# echo mem > /sys/power/state

<after wakeup>

# cat /debug/pm_debug/count
# cat /debug/pm_debug/registers/1

yes, yes, and yes.

Nope, I have the following kernel message:

OMAP clockevent source: GPTIMER12 at 32768 Hz

and the following Kconfig options (also see the attached .config)

# CONFIG_OMAP_MPU_TIMER is not set
CONFIG_OMAP_32K_TIMER=y

regarding the per_clkdm. Debug outpout also modified to display all

Not familiar with the all u-boot versions for this board, but is this
u-boot out of Steve Sakoman's tree?  I had lots of problems with the
TI bootloader leaving Beagle in a strange state and switched to using
the one from Steve's tree.  I have X-Loader 1.41 and:

  U-Boot 2009.01-rc1-00067-g8c6db17 (Jan 15 2009 - 16:31:00)

Right, I forgot Beagle is using GPT12, not GPT1.  nevermind.

First recommendation is to upgrade your bootloder:

  http://elinux.org/BeagleBoard#U-Boot

The earlier bootloaders seem to be blindly enabling reserved bits in
some of the PM registers which can leave the chip in an undefined
state.

Hmm, you have rootfs on NAND.  I haven't tested NAND to know if that
driver might prevent RET.  It "should" be fine, but I am not sure. I
know that OneNAND doesn't, and MMC doesn't.  Any chance you could try
with rootfs on MMC?

I also recommend you boot with minimal rootfs by appending 'init=/bin/sh'
to the commandline.   That elminates any userspace stuff for now that might
be interfering as well.

The main thing that I see in this dump is that some of the bits marked
reserved in the TRM (such as SSI, SDMA etc.) are not auto-idled.  The
kernel isn't currently taking care of these corner cases and relies on
the bootloader not to blindly enable things.

After you update bootloaders, could you post the same results?

Thanks,

Kevin

Neato :) This is still with all the user processes running an with a
NAND filesystem. I'm still getting rather high ~80mA@5V power
consumption, so I'll need to further investigate what rails the
twl4030 is actually turning off.

Great!  glad it worked for you.

The kernel has some work to do to be sure that *everything* is
properly init'd to allow proper idle states.  Until then,
unfortunately we have to rely on more gentle bootloaders.

And FWIW, on my Beagle, I've never seen < 80mA either, but I haven't
done any further digging.
