09:08 <pivi> Hello, currently debugging an issue in which it seems we get non existing interrupts from an I2C device, AM62 running on TI Linux 6.1. The interrupt line is just the usual GPIO with a pull-up. I could add some debouncing on the pin, however from what we can tell so far (to be confirmed) there are no glitches of any kind on the phisical signal. It seems that the SoC is inventing an additional interrupt,

09:08 <pivi> just after the real one, on some situation

09:10 <pivi> I remember about some issue on the beagleplay with the HDMI hotplug interrupt, I assumed it was a real glitch on the external signal there, and not something "invented" from the SoC. Am I wrong? Is there some known issue on this regard?

16:30 <bryanb> pivi: there was this https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c770657bd2611b077ec1e7b1fe6aa92f249399bd though I think this is TI's v6.1 kernel...

16:37 <bryanb> yeah it was backported by Greg in v6.1.28... so that may not be the culprit

16:41 <pivi> bryanb: the spurious interrupt is just a gpio interrupt, not the I2C one (it happens to come from an I2C components, however)

16:49 <pivi> we'll do some more test tomorrow, maybe we are just overlooking something obvious
