- Increment nmi_seen on each WDT expiry NMI (only when watchdog is logically STARTed and extension state is valid).
- If nmi_seen < n: intermediate — bk_wdt_start(next_slice_ms), clear s_nmi_occur (or equivalent) so the “second NMI hard hang” does not trigger on legitimate chained expiries; if int_mode with a user handler, do not call the handler on intermediates; return.
- If nmi_seen == n``: final — **reset nmi_seen`, then existing reset / PANIC / int_mode handler path.

When the config is enabled, the maximum value is 32,767.
config ARMINO_WDG_SLICE_MAX_MS
int "Max WDT slice (ms) for software-extended timeout"
default 30000
range 1 32767
But this shows 60,000 at disabled.
Is this right?

Ohh, Thank you Mr Chang. You remind me. I will change the default value of source code as 30000 ms.

I have changed the default ARMINO_WDG_SLICE_CAP_MS to 30000 to match Kconfig defaults.

Sorry but I don't get what the configs are and how to use them. Could you explain them?

Hello @sunghan-chang
- ARMINO_WDG_SLICE_MAX_MS
What it is: The longest one hardware reload is allowed to be (in ms), when the driver splits a long logical timeout into multiple slices.
How it’s used: The real slice length is min(this Kconfig value, chip hardware max). Smaller slice → more NMI/reload steps for the same long timeout; larger slice → fewer steps (still capped by hardware).
How to set it: Pick something in 1…32767 that fits your tolerance for how often the watchdog is re-armed. Default 30000 is a reasonable starting point.
- ARMINO_WDG_MAX_SOFT_TIMEOUT_MS
What it is: The maximum logical timeout userspace may request via WDIOC_SETTIMEOUT / settimeout (ms). Values above this are rejected (EINVAL).
How it’s used: Set it to the longest timeout your product allows (e.g. 5 minutes default, or up to 86400000 if you really need a day).
In one line: Slice max = size of each hardware chunk; soft max = largest user-visible timeout you allow.

You changed malloc to zalloc at line 681. Those initializations look duplicated.

Hello @sunghan-chang
Yes. With kmm_zalloc, those four assignments are redundant, I have removed the lines 696–699 and rely on zalloc. Behavior stays the same as before.

I tested this locally
but It fails when the timeout was set to 30001.
actually it's not used normally but it's bug in software so please check this.

This is pseudo code I used to test the watchodg function. ioctl(fd, WDIOC_SETTIMEOUT, 10000);
ioctl(fd, WDIOC_START, 0);
usleep(1000 * 1000);
ioctl(fd, WDIOC_GETSTATUS, before_status)
ioctl(fd, WDIOC_PAUSE, 0);
usleep(1000 * 1000);
ioctl(fd, WDIOC_RESUME, 0);
usleep(200 * 1000);
ioctl(fd, WDIOC_GETSTATUS, after_status)[before] flags=0x3 timeout=10000 timeleft=9000
[after] flags=0x3 timeout=10000 timeleft=1168241904 |
…gle hardware window - Increment nmi_seen on each WDT expiry NMI (only when watchdog is logically STARTed and extension state is valid). - If nmi_seen < n: intermediate — bk_wdt_start(next_slice_ms), clear s_nmi_occur (or equivalent) so the “second NMI hard hang” does not trigger on legitimate chained expiries; if int_mode with a user handler, do not call the handler on intermediates; return. - If nmi_seen == n``: **final** — **reset nmi_seen`, then existing reset / PANIC / int_mode handler path.
