Subject: pm-core broken

Hi Kevin,

Just fyi, I tested pm-core(no patches of mine) against SDP3430(ES3.1) and Beagle Rev C1(ES3.0) (that is the only board I could dig up): both fail - I think basically <3630 is broken atm!.

Beagleboard:
with omap2plus_defconfig + MLO, u-boot.bin from
http://www.angstrom-distribution.org/demo/beagleboard/
filesystem is a minimal busybox that I had built and init=/bin/sh to prevent any other apps running in the background - I use the same on SDP3630 and 3430 platforms.

branch: pm-core (from your tree).
defconfig: omap2plus_defconfig - no changes other than disable RM680 board - currently causes a build failure.

test script - same one I had send to ML earlier today replica here: http://pastebin.mozilla.org/889933

[Hiremath, Vaibhav] Nishant,

I am also seeing similar behavior on OMAP3EVM (AM/DM3730), where it does fail with message "Powerdomain (core_pwrdm) didn't enter target state 0". But somehow I am not seeing issues with DSS power domain, not sure what could be happening.

Hi Kevin,

Just fyi, I tested pm-core(no patches of mine) against SDP3430(ES3.1) and Beagle Rev C1(ES3.0) (that is the only board I could dig up): both fail - I think basically <3630 is broken atm!.

Beagleboard:
with omap2plus_defconfig + MLO, u-boot.bin from
http://www.angstrom-distribution.org/demo/beagleboard/
filesystem is a minimal busybox that I had built and init=/bin/sh to prevent any other apps running in the background - I use the same on SDP3630 and 3430 platforms.

branch: pm-core (from your tree).
defconfig: omap2plus_defconfig - no changes other than disable RM680 board - currently causes a build failure.

At least for Beagle (and I assume it's same for SDP, but don't have one to test with) the problem is that u-boot leaves the USB OTG block in a state that does not idle, and thus prevents CORE from hitting RET.

The solution: ensure the USB OTG block is reset.

Also in my tree, threre is an usb-otg-reset branch which you can merge with pm-core to test if this helps.

Until we have the USB OTG hwmod conversion merged, this temporary hack is needed. After conversion to hwmod, all hwmod will be reset during boot so we are not affected by bootloader (mis)behavior.

Arrgh.. we have some sort of regression for .37 formal release (off will probably broken as a result without these patches no for mainline bootloaders/custom bootloaders that dont understand the dependency clearly?).

Anyways, with the 5 patches in usb-otg-reset - test results:
SDP3630 (ES1.0):

SUSPEND:OFF test | PASS | OFF: 0->1| RET:0 ->0 (8 sec)
SUSPEND:RET test | PASS | OFF: 1->1| RET:0 ->1 (6 sec)
IDLE:OFF test | PASS | OFF: 1->22| RET:1 ->1 (21 sec)
IDLE:RET test | PASS | OFF: 22->22| RET:1 ->24 (21 sec)

SDP3430 (ES3.1):

SUSPEND:OFF test | PASS | OFF: 0->1| RET:0 ->0 (7 sec) 
SUSPEND:RET test | PASS | OFF: 1->1| RET:0 ->1 (6 sec) 
IDLE:OFF test | PASS | OFF: 1->21| RET:1 ->1 (22 sec) 
IDLE:RET test | PASS | OFF: 21->21| RET:1 ->23 (21 sec)

Beagle C1 (ES3.0):

SUSPEND:OFF test | FAIL | OFF: 0->0| RET:0 ->0 (6 sec) 
SUSPEND:RET test | FAIL | OFF: 0->0| RET:0 ->0 (6 sec) 
IDLE:OFF test | FAIL | OFF: 0->0| RET:0 ->0 (21 sec) 
IDLE:RET test | FAIL | OFF: 0->0| RET:0 ->0 (21 sec)

Your Beagle u-boot must be leaving something else on besides OTG. I'm using a relatively recent u-boot

    U-Boot 2010.12-rc1 (Nov 16 2010 - 08:31:35)                                     

that I built from source for my Beagle C3 (ES3.0), and suspend/idle test works for me:

SUSPEND:OFF test | PASS | OFF: 0->1| RET:0 ->0 (6 sec) SUSPEND:RET test | PASS | OFF: 1->1| RET:0 ->1 (6 sec) IDLE:OFF test | PASS | OFF: 1->4| RET:1 ->4 (21 sec) IDLE:RET test | PASS | OFF: 4->4| RET:4 ->11 (21 sec)

Is it still CORE that's not hitting RET for you?

yeah, I just think I am darned blind! DSS power domain did not reach state on Beagle and am guessing that could be due to the evil bootloader I was using - anyways, hoping once Senthils' hwmod patches make in, it should be fixed as well.. unless someone has a reset of DSS clock patch or something.. similar to OTG. arrgh.. as far as I am concerned, problem known at least! for some reason, latest 201012-rc1|2|master etc u-boot.bin is goofing up on me.. will look at that later on if no one beats me to it.
