Other Parts Discussed in Thread: AM3359, TPIC2810, PCA9536, SN65HVS882, TPS65910

Tool/software: Linux

hi, I am debugging our own board  and found a "sched: RT throttling activated"n issue.
our processor is  am3358 and we connect two DP83640s to pru MII interface.

right now we can boot up linux  successfully.
but when I plug in a network cable  
the system become very slow and displayed in serial port:

[  395.943979] sched: RT throttling activated

[  416.973984] NOHZ: local_softirq_pending 10e
[  416.983984] NOHZ: local_softirq_pending 10e

or sometime change the number 10e to 106:

[  164.954056] NOHZ: local_softirq_pending 106


I have search google and found some similar problems, but I can find a good solution:

    Hi,

    I am looking into this.

    Can you share your bootlog & dts file?

    Best Regards,

    I have attached log and dts file in last line.
  • 0 in reply to deliang zheng

    I compared my log with ICE2 board boot log and found these two sentence:

    42.642687] irq: no irq domain found for /ocp/pruss@4a300000/intc@4a320000 !
    [ 42.744251] irq: no irq domain found for /ocp/pruss@4a300000/intc@4a320000 !

    but I check my dts file , there are interrupts:

    /* PRUSS - Ethernet 1 */
    pruss_emac0: ethernet-mii0 {
    phy-handle = <&pruss_eth0_phy>;
    phy-mode = "mii";
    interrupts = <20>, <22>;
    interrupt-names = "rx", "tx";
    /* Filled in by bootloader */
    local-mac-address = [00 00 00 00 00 01];
    };

    /* PRUSS - Ethernet 2 */
    pruss_emac1: ethernet-mii1 {
    phy-handle = <&pruss_eth1_phy>;
    phy-mode = "mii";
    interrupts = <21>, <23>;
    interrupt-names = "rx", "tx";
    /* Filled in by bootloader */
    local-mac-address = [00 00 00 00 00 02];
    };
    is there anything I missed in dts?

    hi, Yordan,

    I have googled a lot but unfortunately did not get any good info.
    Do you have any advice?

    Best regards

    Hi Deliang,

    I was not able to find the "status" parameter in your pruss_eth dts node. How (at which point) do you enable the pruss_eth?

    Also check the am335x-icev2.dts, there is additional &pruss_soc_bus node.

    Specifically the message:
    sched: RT throttling activated
    is printed from kernel/sched/rt.c:
    balance_runtime(rt_rq);
    runtime = sched_rt_runtime(rt_rq);
    if (runtime == RUNTIME_INF)
    return 0;

    if (rt_rq->rt_time > runtime) {
    struct rt_bandwidth *rt_b = sched_rt_bandwidth(rt_rq);

    /*
    * Don't actually throttle groups that have no runtime assigned
    * but accrue some time due to boosting.
    */
    if (likely(rt_b->rt_runtime)) {
    rt_rq->rt_throttled = 1;
    printk_deferred_once("sched: RT throttling activated\n");

    This may be due to some task exceeding its dedicated runtime...
    Then the other issue:

    comes from kernel/time/tick-sched.c:
    if (ratelimit < 10 &&
    (local_softirq_pending() & SOFTIRQ_STOP_IDLE_MASK)) {
    pr_warn("NOHZ: local_softirq_pending %02x\n",
    (unsigned int) local_softirq_pending());
    ratelimit++;
    }

    Best Regards,
    Yordan

    and also I can not find it in the dts directory:
    ~/ti-processor-sdk-linux-rt-am335x-evm-03.01.00.06/board-support/linux-rt-4.4.19+gitAUTOINC+f572d285f0-gf572d285f0/arch/arm/boot/dts$ grep -ir pruss_soc_bus ./
    tqma28bsp109@tqma28bsp109-VirtualBox:~/ti-processor-sdk-linux-rt-am335x-evm-03.01.00.06/board-support/linux-rt-4.4.19+gitAUTOINC+f572d285f0-gf572d285f0/arch/arm/boot/dts$

    so I think maybe your dts is different version. which version do you use?

    and what' more, we use the same dts for another board which use different phy, and the PRU works.

    hi, Yordan,

    today I download latest SDK ti-processor-sdk-linux-rt-am335x-evm-04.02.00.09
    and use create-sdcard.sh to create a new SD card with prebuild images.
    then I test it in ICE board(rev 2.1) and also fond the some print information:
    [ 107.051212] NOHZ: local_softirq_pending 08
    [ 107.057181] NOHZ: local_softirq_pending 08

    hi,

    the problem actually is not fixed, and I test the lasted version SDK ti-processor-sdk-linux-rt-am335x-evm-04.02.00.09 in ICE board and found the same problem.

    my ICE board version is REV2.1A

    I create a new sd card using create-sdcard.sh with SDK prebuild images,

    Boot the ICE board and wait the board boot up completely.

    then I plug network cable to eth0, the message displayed:

    [  114.017225] sched: RT throttling activated


    the whold logs as below:

    Hi,

    Thanks for trying the lastest SDK, are you using the pre-built images that are downloaded from the SDK? Looking at the log file it does not appear that you are setting any applications to run. Could you please describe the network that you are plugging into? Such as is there any traffic on it? Could also attach top again for this test?

    Best Regards,
    Schuyler

    Hi,

    Apologies, I was not looking at the right area in the post. You are using the pre-built images and the 2.1A version of the ICE board. So only the question of the network traffic. Another thing is what are the jumper setting that are setup on the board.

    Best Regards,
    Schuyler

    hi, Schuyler,

    Thanks for your reply.
    yes, I use pre-built images and I did not run any own application, only boot up the system with a new SD card which only installed default images and rootfs.
    I connect ice2 board to an 8-port switcher that connects my PC and then wlan to our own office network.
    the jumper setting is that the two pins near LED side connected. I think this is ok because I have tested it for version ti-processor-sdk-linux-rt-am335x-evm-03.01.00.06. the PRU works perfectly.

    I will submit the TOP info soon.

    Best regards
    Dylan

    hi, Schuyler,

    is there any difference for PRU between am3358 and am3359?
    we are use am3358 for our own board and it doest not work, which I describe in the first post in this topic.

    PM: Cannot get wkup_m3_ipc handle

    hi,

    I turn to my own board and trace the prueth.c code and found that :

    when I plug in my cable into RJ45 connector,
    prueth_tx_enqueue() which is in file prueth.c ,is called and 17 packages are copied from DRAM to OCMC.
    after that the function return -ENOBUFS, which means the buffer is full.

    there is a comment at the end of this function:
    "
    /* update the write pointer in this queue descriptor, the firmware
    * polls for this change so this will signal the start of transmission
    */
    "
    it seems that the PRU firmware did not get the data and transmit it to phy.
    I can check that the pru is running by the log:

    [ 19.885806] remoteproc2: powering up 4a338000.pru1
    [ 19.891057] remoteproc2: Booting fw image ti-pruss/am335x-pru1-prueth-fw.elf, size 4830

    [ 20.179736] remoteproc2: remote processor 4a338000.pru1 is now up.

    but I am wondering if there is any way we can check if data processing is triggered in PRU?

    Best regards

    Hi Dylan,

    Thanks for the info, I will need to discuss with PRU member on the team. Thanks for the top attachment, things do line up better. The ksofttimerIrq is taking all the system time and probably explains the NO_HZ messages.

    Could you please add an attachment of the ifconfig eth0 please? And also ethtool eth0 please?

    Best Regards,

    Hi,
    Are you doing anything to take the eth0 link down? When you plug the SD card into the ICEv2 board, when you run top are you seeing the same results? ksofttimerd taking 95% of the processor after you plug in the ethernet cable?

    Best Regards,

    Hi, Schuyler,

    my operation steps like this:
    (1) insert SD card
    (2), power the ICE board
    (3) when board boot up and login as root;
    (4) use ifconfig command to see if the ethernet ports are there ; and also run TOP if need.
    (5) plug in the network cable
    (6)wit for several seconds, the "sched: RT throttling activated" will happen,
    (7) if plug out the cable quickly after step 6, ( within 5 seconds), then the system will continue running(I can operate through serial port).
    otherwise the system will hold completely after step 6 after long time( like 5 minutes).

    (1)Are you doing anything to take the eth0 link down?
    nothing, i only use ifconfig eth0 to see the status of eth0

    (2) When you plug the SD card into the ICEv2 board, when you run top are you seeing the same results?
    I insert SD card before power on the board. after board power on , if no cable connected, I run top , can not see the same result.

    (3) ksofttimerd taking 95% of the processor after you plug in the ethernet cable?
    ksofttimerd taking 95% of the processor only happens when I plug in the cable.

    Hi,

    I apologize because I was not specific when I ask about the SD card in the ICEv2 board. I want to see if SD card that you have running in the ICEv2 board shows the ksofttimerd at 95% with the cable attached. I am trying to see if the ksofttimerd is behaving the same way on the two boards.

    Hi Schuyler,

    I just wanna clarify my previous answer.

    Our ICEv2 board is running on a SD card with prebuild image without any modifications (not TFTP method).

    I did unplug the Ethernet cable from the board after "NOHZ: local_softirq_pending 08" is shown on the console, sorry I wasn't clear on that.

    When the board wasn't connected to the network it was running fine. When I executed top command ksofttimerd is running at approx 5% to 10%.

    However a few seconds after it was connected to the Ethernet network, the console started outputting "NOHZ: local_softirq_pending 08" message. Typing in the console became very sluggish. When I executed top command I could see ksofttimerd is using 95% of CPU, which explains why the board becomes unresponsive. The board recovered as soon as I unplug the ethernent cable and the CPU usage of ksofttimerd dropped back to around 5% of CPU. If I left the ethernet cable plugged in when the issue occurred, the board died after a couple of minutes and a power cycle is required in order to bring it back.

    I have also tested with CPSW on those 2 ports (ie changed the jumper setting behind the ethernet port) and I didn't see the same problem. The board is working fine with CPSW. Unfortunately we required PRU ethernet not CPSW.

    Thanks again for your help.


    Regards

    Hi Dylan,

    Thank you for the clarification, I believe I understand better now what you are telling me. Due to the issue you are seeing with the pre-built images on the ICEv2 board is there a chance you could download the latest TI Linux RT 4.02 SDK and try the same test as an experiment on the newer SDK?

    Best Regards,

    hi, Schuyler,

    Good news, We have found our own board problem.
    I use the command " omapconf show dpll cfg" and find the M4 clock is not 200MHz.
    after we change the dpll registers to make M4 output 200MHz. then the PRU is working .


    for the ICE board, we have download latest SDK ti-processor-sdk-linux-rt-am335x-evm-04.02.00.09 and
    tested it. Please see my previous posts.

    Because we need the PRP/HSR feature in our new projects,
    so right now we are considering which version SDK is suitable for us to port to our own board.
    we hope we can use the latest version, so we still need your help to get the latest version working in ICE board, which then we could test the PRP /HSR performance.

    Best regards
    Dylan.

    hi, Schuyler,

    I think I can close this thread, as our own board's problem is not the same with ICE2 board's.
