Get a stuck in a tegra186_gpio_irq error loop when powering on device

benjamin.pepe · March 18, 2025, 3:06am

Hi community:
I have a custom board with HDMI ports running L4T R36.3 using an Orin NX.

When I power on my device using PoE with no peripherals attached except for a uart cable. I occasionally get stuck in a loop of tegra186_gpio_irq errors. I have read in other form posts about it being related to HDMI hotplug. However, in those posts that problem is said to have been resolved in r36. Also I do not have a HDMI plugged in nor plugin one to trigger that kind of error.

When trying to reproduce this error I have been unplugging the ethernet cable(PoE power) and plugging it back in to power off and power on the device. The error occurs right before the login screen on the uart logs.

[   10.367675] EXT4-fs: Warning: mounting with data=journal disables delayed allocation, dioread_nolock, O_DIRECT and fast_commit support!

[   10.965273] ---[ end trace c06877825e2db86f ]---

I was wondering if anyone has an idea what tegra186_gpio_irq error means and or what is causing the error?

Here are the system logs.

Hi benjamin.pepe,

It seems you’ve some customization on your board since we don’t have HDMI on Orin Nano devkit with JP6.0(r36.3.0).

Would you hit the boot issue if you don’t connect HDMI and PoE?
Please help to clarify what causes the boot stuck.

It seems stuck in irq handler function, we want to know what driver calls that irq handler.
Please share the full serial console log for further check.

Hi Kevin,

Thank You for the quick response.

I do not have any HDMI connected to the board when powering it on, only PoE and a uart cable.
I will try reproducing the error by powering on the board using the DC plug.

I have attached the full serial console log.
full_serial_log.log (85.8 KB)

Please let me know if you need more information.

benjamin.pepe · March 18, 2025, 8:11am

I was able to reproduce the error by unplugging and plugging in the dc power jack with no HDMI cable connected only uart cable.

WayneWWW · March 18, 2025, 8:53am

Could you try to totally disable your HDMI things in the device tree first and see if you can still trigger this error?

tegra186_gpio_irq is just to handle irq for any GPIO. It does not mean everything from it is 100% from HDMI.

benjamin.pepe · March 18, 2025, 8:58am

Ok I will try disabling HDMI things in the device tree.

benjamin.pepe · March 19, 2025, 5:00am

I disabled the HDMI things in the device tree and the error still occurred.

Do you have any recommendations or insight?

If it is GPIO related I can try disabling things that use GPIO one by one.

Thank You

Hi,

Could you add some prints in kernel/3rdparty/canonical/linux-jammy/kernel-source/drivers/gpio/gpio-tegra186.c → tegra186_gpio_irq function?

I would like to check what was the address of GPIO that triggers this IRQ.

base = gpio->base + port->bank * 0x1000 + port->port * 0x200;

benjamin.pepe · March 19, 2025, 8:31am

Ok I will add some logs.
Did you just want the pointer stored in base?
or is there anything else you want?

WayneWWW · March 19, 2025, 10:12am

Please also check the port->bank and port->port. This will make the GPIO pin more clearly.

For example, GPIO G,5 means bank=G and pin = 5. “G” will map to another value defined in tegra234-gpio.h too.

benjamin.pepe · March 21, 2025, 1:18am

Sorry for the delay,

These were the results before the error.

Based on you explanation it seems to be GPIO Q,5 using the TEGRA234_MAIN_GPIO definition as reference. I am looking to see if we use that port and pin.

So we use GPIO Q,5 as a low output, so it is odd that it is associated with an interrupt.

Here how we implemented GPIO Q,5.

			gpio-output-low = <
				TEGRA234_MAIN_GPIO(Q, 5)
				...
				>;

soc_gpio32_pq5 {
				nvidia,pins = "soc_gpio32_pq5";
				nvidia,function = "rsvd0";
				nvidia,pull = <TEGRA_PIN_PULL_NONE>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
				nvidia,io-high-voltage = <TEGRA_PIN_DISABLE>;
				nvidia,lpdr = <TEGRA_PIN_DISABLE>;
			};

Do you have any ideas to what could cause this?

Thank You

WayneWWW · March 21, 2025, 3:26am

No, Q,5 is a wrong example. Please ignore it.

benjamin.pepe · March 21, 2025, 4:32am

So the results in the logs below do not mean that GPIO Q,5 is causing the error loop?

Could you also share what did you add in the code? Just want to know what is the format of each variables there.

benjamin.pepe · March 21, 2025, 5:48am

I only added the pr_info’s

static void tegra186_gpio_irq(struct irq_desc *desc)
{
	struct tegra_gpio *gpio = irq_desc_get_handler_data(desc);
	struct irq_domain *domain = gpio->gpio.irq.domain;
	struct irq_chip *chip = irq_desc_get_chip(desc);
	unsigned int parent = irq_desc_get_irq(desc);
	unsigned int i, j, offset = 0;

	chained_irq_enter(chip, desc);

	for (i = 0; i < gpio->soc->num_ports; i++) {
		const struct tegra_gpio_port *port = &gpio->soc->ports[i];
		unsigned int pin;
		unsigned long value;
		void __iomem *base;

		base = gpio->base + port->bank * 0x1000 + port->port * 0x200;

		/* skip ports that are not associated with this bank */
		for (j = 0; j < gpio->num_irqs_per_bank; j++) {
			if (parent == gpio->irq[port->bank * gpio->num_irqs_per_bank + j])
				break;
		}

		if (j == gpio->num_irqs_per_bank)
			goto skip;

		value = readl(base + TEGRA186_GPIO_INTERRUPT_STATUS(1));
		pr_info("Base = %p | gpio->base = %d | port->bank = %u | port->port = %u\n", base , gpio->base, port->bank, port->port);
		for_each_set_bit(pin, &value, port->pins) {
			pr_info("pin = %u\n", pin);
			int ret = generic_handle_domain_irq(domain, offset + pin);
			WARN_RATELIMIT(ret, "hwirq = %d", offset + pin);
		}

skip:
		offset += port->pins;
	}

	chained_irq_exit(chip, desc);
}

Hi,

Sorry that I just notice you could directly print the port->name variables.

I did not look too much into the structures.
I will add that and get back to you when i have the logs.

benjamin.pepe · March 21, 2025, 7:12am

Here is the log

Mar 21 06:53:35 [kern] kernel:[    9.451438] GPIO IRQ triggered: Port Q, Pin 5

WayneWWW · March 21, 2025, 7:15am

OK, then it is really the Q,5 GPIO as my first guess.

This is set to GPIO input by default. Is that thing in use on your board?

Are you sure your change to make it as gpio output low really takes effect?
