TDA2PXEVM: Enabling Watchdog timer in hlos use case

H Chinmayee Rao
Intellectual 460 points


Hello,

I want to enable watchdog timer for an hlos use case to reset when the application is stuck due to software or hardware fault. Can someone please guide with this.

Thanks in advance!

Best Regards

    Hi Chinmayee,

    If you search your boot log then you should be able to see a trace like below:

    "[    7.784962] omap_wdt: OMAP Watchdog Timer Rev 0x01: initialimeout 60 sec"

    By default there is already a watchdog running in Linux with timeout of 60 seconds. Is that good enough for you?

    Hi Keerthy,

    Thank you for the reply.

    In my boot log I am not finding "omap_wdt: OMAP Watchdog Timer Rev 0x01: initialimeout 60 sec".
    Where should I enable it?
    And can we configure timeout to less than 60 seconds?

    Best Regards

    Hi Chinmayee,

    DISABLE_COMPLETE(wdt2);

    Can you remove that from: dra76-evm-infoadas.dts file that should enable the watchdog and you should
    be able to see that print.

    Also default is 60 Seconds and you should be able to change that in:

    drivers/watchdog/omap_wdt.h in your Linux source code:

    #define TIMER_MARGIN_DEFAULT 60

    to the value you want.

    Hi Keerthy,

    I am working along with Chinmayee.

    We have removed the DISABLE_COMPLETE(wdt2); from dra76-evm-infoadas.dts and is able to list in /dev/watchdog and /dev/watchdog0. Also the kernel message omap_wdt: OMAP Watchdog Timer Rev 0x01: initialimeout 60 sec is seen now.


    Our aim is to reset the board if the application is stuck at some point.

    I had some doubts regarding these.

    1. What should happen if we change TIMER_MARGIN_DEFAULT to 4 sec ? 
    2. Does it affect only the A15 core or other cores also ?
    3. What can we do to reset the board if the application (apps.out) gets hanged at IPU, DSP cores, etc.
    4. Do we need any modifications in the usecase so that it can help reset when it gets hanged at cores other than A15 ?

    Padmesh,

    1) Watchdog should be pet every 4 Seconds.
    2) System watchdog like the one specified should reset the soc.
    3) & 4) I will come back.

    I want to understand your use case better. I was under the impression that application was run on HLOS
    i.e Linux. Can you give more details on the use case?

    Hi Keerthy,

    Our usecase is as follows:

    NullSource (A15) -> Decode -> VPE -> Sync -> Dup -> Gate_Alg1 -> Alg1 (DSP1) -> Display_HDMI
                                  
    Dup -> Gate_Alg2 -> Alg2 (DSP1) -> SgxFrmcpy (A15) -> Display_LCD
     
    Dup -> Alg3 (DSP1)
     
    //Dynamic overlays
    ssdOverlayLink (IPU1_0) -> Display_Grpx



    Our main purpose for using watchdog is to reset the system when code is stuck somewhere for more than 4secs.

    So what specific function calls or system calls does the watchdog need to reset the soc?

    Hi Chinmayee/Padmesh,

    There is only one system level watchdog and now that Linux owns it then it will reset only
    when A15 hangs and not when other cores hang.

    That said: our remoteproc driver contains kind of soft watchdog support for the remoteprocs, including DSP. CONFIG_OMAP_REMOTEPROC_WATCHDOG can be used to enable it, and basically it is just a soft timer that the DSP would pet as if it was a watchdog. When it expires, it will interrupt a15 kernel driver and it will decide what to do with it.

    Hi Keerthy,

    As mentioned,

    1. DISABLE_COMPLETE(wdt2) is removed from dt
    2. And CONFIG_OMAP_REMOTEPROC_WATCHDOG is also enabled

    But when we crash the ipu or dsp firmwares purposefully, the SoC is not reset.

    I suspect, do we need to remove the /delete-property/ watchdog-timers; line from the dra76-evm-infoadas.dts

    Our current dt is having the following configuration,

    #include "dra76-evm.dts"

#define DISABLE_PRCM(label) &label { ti,no-idle; ti,no-reset-on-init; }
#define DISABLE_COMPLETE(label) &label { status = "disabled"; ti,no-idle; ti,no-reset-on-init; }
#define LATE_ATTACH(label) &label { ti,late-attach; ti,no-idle; ti,no-reset-on-init; }

    Hi Padmesh,

    Yes delete-property will remove that soft watch dog timers implemented for the remote cores. You need to remove
    that line and ensure that the code related to those watchdog timers is executed.

    Hi Keerthy,

    I have removed the /delete-property/ 

    By code do you mean I need to do any changes in drivers/remoteproc/omap_remoteproc.c ? and What should that be ?

    Or Is anything needed to be mentioned in the usecase code to handle the reset ?

    Hi Padmesh,

    I just wanted you to cross check if the code in: drivers/remoteproc/omap_remoteproc.c

    ret = request_irq(timers[i].irq, omap_rproc_watchdog_isr, IRQF_SHARED,
					  "rproc-wdt", pdev);

    Is being requested & code under CONFIG_OMAP_REMOTEPROC_WATCHDOG is getting executed
    by adding some debug prints.

    Finally omap_rproc_watchdog_isr is getting called or not.

    Hi Keerthy,

    I have added few kernel prints inside and outside the function omap_rproc_watchdog_isr, but nothing was seen when the app got stuck. 

    I see that no calls are gone to omap_rproc_watchdog_isr.

    I made the following changes in dt by removing the  lines /delete-property/ watcdog-timers;

    &ipu1 {
	timers= <&timer9> , <&timer11>;

};

&ipu2 {

};

&dsp1 {
	
};

&dsp2 {
	
};

    And the prints added in omap_remoteproc.c as follows,

    static irqreturn_t omap_rproc_watchdog_isr(int irq, void *data)
{
	struct platform_device *pdev = data;
	struct rproc *rproc = platform_get_drvdata(pdev);
	struct omap_rproc *oproc = rproc->priv;
	struct device *dev = &pdev->dev;
	struct omap_rproc_pdata *pdata = dev->platform_data;
	struct omap_rproc_timer_ops *timer_ops = pdata->timer_ops;
	struct omap_rproc_timers_info *timers = oproc->timers;
	struct omap_dm_timer *timer = NULL;
	int num_timers = oproc->num_timers + oproc->num_wd_timers;
	int i;
	printk(KERN_INFO" Inside omap_rproc_watchdog_isr()");
	for (i = oproc->num_timers; i < num_timers; i++) {
		if (timers[i].irq > 0 && irq == timers[i].irq) {
			timer = timers[i].odt;
			break;
		}
	}

	if (!timer) {
		dev_err(dev, "invalid timer\n");
		printk(KERN_INFO" Inside omap_rproc_watchdog_isr(): invalid timer");
		return IRQ_NONE;
	}
	printk(KERN_INFO" Inside omap_rproc_watchdog_isr(): Calling timer_ops->ack_timer_irq(timer)");
	timer_ops->ack_timer_irq(timer);

	printk(KERN_INFO" Inside omap_rproc_watchdog_isr(): Calling rproc_report_crash()");
	rproc_report_crash(rproc, RPROC_WATCHDOG);

	return IRQ_HANDLED;
}
.
.
.
..
		if (i >= oproc->num_timers) {
			timers[i].irq = timer_ops->get_timer_irq(timers[i].odt);
			if (timers[i].irq < 0) {
				dev_err(dev, "get_irq for timer %p failed: %d\n",
					np, timers[i].irq);
				printk(KERN_INFO"get_irq for timer %p failed: %d\n",
					np, timers[i].irq);
				ret = -EBUSY;
				goto free_timers;

			}

			ret = request_irq(timers[i].irq,
					  omap_rproc_watchdog_isr, IRQF_SHARED,
					  "rproc-wdt", pdev);
			if (ret) {
				printk(KERN_INFO"error requesting irq for timer %p\n",

    What other things do we need to look into ?

    Does this particular service message have any effect on the timer

    Hi Padmesh,

    I assume that the request_irq for watchdog went fine. Can you attach the dtb that you are
    using with all the latest changes in place?

    Hi Padmesh,

    dsp1 is requesting for one watchdog timer.
    dsp2 is requesting for one watchdog timer.
    ipu1 is requesting for two watchdog timers.
    ipu1 is requesting for two watchdog timers.

    I am on a different hardware but essentially i see 6 watchdog interrupts under /proc/interrupts:

    cat /proc/interrupts | grep wdt
     56:          0          0      CBAR  35 Level     rproc-wdt
    9:          0          0      CBAR  38 Level     rproc-wdt
     60:          0          0      CBAR  39 Level     roc-wdt
     61:          0          0      CBAR  40 Level     rpc-wdt
     62:          0          0      CBAR  41 Level     rproc-wdt
     65:          0          0      CBAR 339 Level   rproc-wdt

    Can you confirm the same at your end. The numbers might be different but
    looking at your attached dts(dtb converted) we should see 6 entries. This will
    confirm that all the IRQs are registered.

    Can you confirm that "ret = request_irq(timers[i].irq,  omap_rproc_watchdog_isr, IRQF_SHARED, "rproc-wdt", rproc);"
    is happening for DSP1's watchdog timer i.e timer10 according to the dts shared earlier?

    Hi Padmesh,

    Understood. Thanks so ipu1 & dsp1's wdt are being registered.

    From the dts shared earlier timer10 is the watchdog for dsp1. Do you load the timer
    in your firmware? From the A15 side the driver clearly mentions that.

    In case of omap_rproc like for example DSP1 which has timer10 as its watchdog:

    &dsp1 {
            mboxes = <&mailbox5 &mbox_dsp1_ipc3x>;
            ti,timers = <&timer5>;
            ti,watchdog-timers = <&timer10>;
    };

    In the code: omap_rproc_request_timer -->
    /* clean counter, remoteproc code will set the value */
             timer->timer_ops->set_load(timer->odt, 0);

    This mean that dsp firmware should be configuring the timer10 value
    as the watchdog timer value upon whose expiry the omap_rproc_watchdog_isr
    will be triggered.

    Are you using custom DSP firmware or the TI firmware for DSP? I believe the DSP firmware
    shared by TI in the /lib/firmware folder for dsp1 should be configuring that. Can you just ensure
    that timer10 is loaded with appropriate value from the DSP firmware?

    Hi Keerthy,

    We are using TI firmware for DSP. 
    To load the appropriate value into timer10 do we need to add anything in firmware?
    Is dra7-dsp1-fw.xe66 giving the value to the timer?

    Hi Chinmayee,

    If you have a debugger can you dump out the timer10 registers to check if it is functional?

    Starting from address: 0x48086000 - 0x4808606C.

    Regards,
