Well perf should work itself OK using the fallback timer-based method, it's specifically this -e mode. The hardware counters are in there and do stuff, the problem is (IIRC overflow) interrupts are prone to get lost, distorting the numbers to uselessness, and that problem is in the ARM core and lay undiscovered for a long while so is in all (AFAIK) shipping chips.

[Bug 709245] Re: ARM SMP scheduler performance bug
Hi Ming-Lei - What I like about your explanation is it allows cache status to be the communication path for network traffic to impact the issue, ie network activity finally spills the cache that does update the qtd descriptor and then we get less deadtime.

[Bug 708883] Re: Panda board shuts down during boot
I was trying to power my Panda board from USB OTG connector, it dies early in boot apparently in xloader or u-boot when connected to a laptop. I did three tests 1) Short the USB OTG 5V pin to the DC Jack 5V pin in case something in the OTG 5V path makes trouble. It still dies in early boot. 2) Remove the D+ and D- wires from the USB cable, still plugged into the OTG socket. It still dies in early boot. 3) Completely remove the connection from the OTG socket, and bring the same laptop USB power to the DC power jack. Boots fine. So it seems that you just need external power coming to the OTG power pin to make the early boot problem. I also tested combinations of DC Jack power with OTG power using different sequencing, DC Jack power couldn't allow it to recover once it was in the process of dying, and you could not start the board again until both power sources were removed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708883 Title: Panda board shuts down during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 708883] Re: Panda board shuts down during boot
Well, there's no reason to expect it should be consistent since we didn't compare which version of Xloader and U-Boot I am running and you already have reason to believe the behaviour depends on that. However what I reported is repeatable on this board with Texas Instruments X-Loader 1.41 (Oct 6 2010 - 17:27:48) U-Boot 2010.09-rc1 (Sep 23 2010 - 11:24:55) If that looks like you "old", working setup maybe you can try that with the USB OTG power to see if that provokes the messed-up boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708883 Title: Panda board shuts down during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 708883] Re: Panda board shuts down during boot
I examined the pandaboard schematics and found that the SYS_BOOT[7..0] pins are set to 1101 by default. These control the actions of the ROM on the OMAP4. b5..b0 select the boot ordering; 000101 means try USB boot first and MMC1 second. In the case that no external power is connected to the USB OTG, the ROM skips initializing the USB unit and boot proceeds normally via MMC1. In the case that there is external power coming to the USB OTG connector, the ROM spends a few seconds trying to bring that up and if it isn't satisfied then proceeds to the second boot option via MMC1. It starts the MMC1 card clock and pulls in X-loader and it starts. However because of some side effect of the ROM having followed a boot path that started the OTG unit, X-loader is unable to operate normally at a couple of points during its initialization. I have just sent some patches to linaro-dev that fix this for me so I am able to boot into Linux OK just from my laptop plugged into the OTG socket on Panda. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708883 Title: Panda board shuts down during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 708883] Re: Panda board shuts down during boot
@Aneesh... my problem was with USB OTG power of the board, it is fixed with the patches but you're right the bug in Launchpad is more about dying later. Like yourself my board is not dying later either. My patch also does prcm_init() earlier but after that there is another problem with using shadow updates of the clock register when EMIF IDLE is disabled; it only updates when the EMIFs are idle (DDR is not busy then). It sat for a long time (minutes at least) in the loop waiting to confirm the shadow update had gone through. @Ricardo... I think there are two issues, mine was crashing early in boot if powered by USB OTG and that's solved by my patches. "Panda board shuts down in boot" described my issue too.

[Bug 708883] Re: Panda board shuts down during boot
Most of this confusion is coming because the LED trigger heartbeat is being built as a module (why?) and not inserted. If you type modprobe ledtrig-heartbeat at the prompt you will get the familiar flashing LED letting you know the board is ON. So I guess the confusion about ON or OFF will be removed anyway if this is added to an initscript. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708883 Title: Panda board shuts down during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I added the modprobe ledtrig-heartbeat to /etc/rc.local for now, although I'm sure there's a better place. I cycled the power 10 times. 9 times it was normal, but one time there was a 30s delay before boot completed. If it delayed 30s with LEDs off, many people will think the board is OFF.

[Bug 708883] Re: Panda board shuts down during boot
After a lot of help from kenws testing, I have a small patch which should stop the Panda going OFF. I can explain why it goes off without the patch, but since TI won't let me have a twl6030 datasheet I can't get right to the end yet. Basically the Panda PMIC is seeing an overcurrent on one of its regulators, and reporting it via b6 of its interrupt sources VXXX_SHORT. Like other PMICs, if something bad like that happens the PMIC gives the CPU a short time to acknowledge the report of the bad news, and if the CPU doesn't come and clear the interrupt within that time, the PMIC will force the device OFF for safety. The mainline twl6030 driver takes the approach that it will mask off all interrupt sources except the ones it is interested in, just MMC card detect and USB OTG ID status at the moment. Therefore if the VXXX_SHORT condition occurs with the driver as it is, the interrupt is not cleared and the PMIC panics forcing the Panda OFF. The patch enables all interrupt sources instead, so the condition is acknowledged. The variation in boards showing the problem or not is explained by the process spread of the overcurrent comparator in the PMIC; I was able to reduce the threshold on mine by lowering Vin and reducing the PMIC temperature so I could control whether VXXX_SHORT was generated or not since the actual current was marginal vs the comparator limit. But since the comparator limit would normally be quite a little bit above the max legal current, it suggests that on one regulator the Panda really is pulling more than it should. So the root cause is genuinely excessive current on one of the regulators, but I don't know which one because I don't have a datasheet (although I would look at the 2.1V one first). The final fix will be to identify the regulator and reduce the current taken. But in the meanwhile this patch should remove the symptom. ** Patch added: "Workaround for Panda overcurrent detect making reboot" https://bugs.launchpad.net/ubuntu/+source/linux-linaro/+bug/708883/+attachment/1853922/+files/panda-twl6030-enable-all-irq-sources.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708883 Title: Panda board shuts down during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
