Hi, since the evaluation in WP76xx not waking up from SPM on GPIO - #16 by simon.naegele , which is now working smoothly, we are going on and found that hwirq: 47 is waking up the module sometimes: Feb 6 07:00:42 swi-mdm9x28-wp user.debug kernel: [ 633.211913] PM: Entering mem sleep Feb 6 07:00:…

maybe related to this : https://www.kernel.org/doc/Documentation/devicetree/bindings/power/avs/qcom%2Ccpr.yaml

does this help? root@swi-mdm9x28-wp:~# cat /proc/interrupts CPU0 16: 5909 GIC 38 arch_mem_timer 17: 3 GIC 59 smp2p 19: 0 GIC 114 nidnt_nidnt 20: 42 GIC 203 601d0.qcom,mpm 21: 0 GIC 35 apps_wdog_bark 25: …

So is it the first or the second column? In my case it would also be 47: 25 GIC 52 cpr, but what does cpr mean?

looks like a bigger thing to investigate :frowning: thanks!

first column seems to be the softirq maybe this column is the hwirq [image]

now it appeared in the list! before it wasn’t there! 57: 10 msmgpio 5 msm_hs_wakeup 78: 3 msmgpio 26 wake-n_gpio26 99: 0 msmgpio 47 gpiolib 105: 0 msmgpio 53 soc:pps.-1 ok, some sort of gpio is the problem. gpiolib so this should be a sysfs G…

didn’t you already prove this here? [image] WP76xx not waking up from SPM on GPIO Legato Application Framework On another module we can see messages from the interrupt on GPIO38, but it’s still not waking up: Jan 17 13:10:54 swi-mdm9x28-wp user.info kernel: [ 150.791732]…

I found it. On our software this is GPIO30, which is configured to be an interrupt. If I don’t export it, it’s not in the list in /proc/interrupts/. We’ll check with the hardware what’s going on during sleep. The GPIOs in the other thread are not a problem, because they are all set to a specific …
