pwm-pio OOPS when enabling on 6.12.34

Open rpdom opened this issue 5 months ago • 8 comments

Describe the bug

When testing pwm-pio on a Pi 5 2GB running an up-to-date Raspberry Pi OS 64-bit Bookworm Lite, I encountered errors which killed the current process.

The dmesg report showed WARNINGS and an OOPS.

Steps to reproduce the behaviour

Install Bookworm Lite using imager.

Run sudo apt update && sudo apt full-upgrade.

Enable pwm-pio in config.txt

dtoverlay=pwm-pio

Reboot.

Then the following command line sequence caused the problem

rpdom@raspberrypi:~ $ cd /sys/class/pwm/pwmchip1/
rpdom@raspberrypi:/sys/class/pwm/pwmchip1 $ cat npwm 
1
rpdom@raspberrypi:/sys/class/pwm/pwmchip1 $ echo "0" >export 
rpdom@raspberrypi:/sys/class/pwm/pwmchip1 $ cd pwm0
rpdom@raspberrypi:/sys/class/pwm/pwmchip1/pwm0 $ echo 50 >duty_cycle 
rpdom@raspberrypi:/sys/class/pwm/pwmchip1/pwm0 $ echo 1000 > period 
rpdom@raspberrypi:/sys/class/pwm/pwmchip1/pwm0 $ echo 1 > enable

At this point the shell exited and dmesg showed the trace.

Seems to be around https://github.com/raspberrypi/linux/blob/rpi-6.12.y/drivers/pwm/pwm-pio-rp1.c#L118 (ppwm->pio is NULL). Candidate for a fix: https://github.com/raspberrypi/linux/pull/6972

Not quite enough context had been transferred from the forum thread :-(

I'd concluded the same thing over container_of not being appropriate in 6.12 - https://forums.raspberrypi.com/viewtopic.php?p=2328072#p2328072 However I was then getting a BUG: scheduling while atomic warning, but ran out of time yesterday to investigate hence asked for an issue to be raised to ensure it didn't get lost.

6by9 avatar Jul 24 '25 09:07 6by9

Good to know. This would have saved me sometime yesterday evening, but it actually it fun to do :) Regarding the atomic warning: Haven't seen this on 6.12.37 with what I was testing, but will test again once the ci is ready.

nbuchwitz avatar Jul 24 '25 09:07 nbuchwitz

@rpdom if you're willing to test the patch, you can do so with sudo rpi-update pulls/6972.

Make sure to have a recovery strategy / backup for the (unlikely) case that the kernel wont boot. I've tested it on a CM5 and everything seems to look ok.

nbuchwitz avatar Jul 24 '25 09:07 nbuchwitz

I'll agree that 6.12 works fine on my 2GB Pi5.

Time to have a quick look as to why it's throwing scheduling errors on 6.15 and 6.16, but that isn't a blocker for now. New PWM drivers are meant to use the waveform API, so it may be something that has crept in with that change.

...

Ah, the PWM device is specified as callable in an atomic context, in which case 1cc2e1faafb3b5a2be25112559bdb495736b5af7 added in 6.13 means the core will grab a spinlock, not a mutex. That explains the atomic context.

That seems to have fixed the problem, thank you. :-)

I’m getting the same "Invalid argument" error when trying to access the Bluetooth socket on my Raspberry Pi 5 running Ubuntu 24.04 Server, and after upgrading my Raspberry Pi OS with apt upgrade. Any chance this issue is resolved in Ubuntu 25.04 Server kernel?

the-braveknight avatar Jul 28 '25 01:07 the-braveknight

The issue is unrelated to Bluetooth (invalid argument is a generic error message). Also as far as I know Ubuntu builds their own Kernel, so the bug report is probably better placed with them. If the same error happens with the latest Raspberry Pi OS and kernel I would suggest to open a new issue here.
