GPD Gyro woes after sleep
I'm still curious whether reading the raw data from sysfs will work on the win 4 after a suspend / resume

GPD Gyro woes after sleep
On the mini, I tried a version of the driver that doesn't set up an IRQ. Reading the raw gyro data still works after a suspend, but I can't get hhd to start with that hacked up driver, just get this in a loop:

if it's fine when you read the data raw, it's probably a buffer problem or hrtimer problem or a timing problem, something like that

yeah, I think that watch command with hhd disabled would help figure that out. If the gyro stops reporting data after a suspend when a trigger has never been set up, it's probably not related to hrtimer

nothing needs to recover for me, I don't get a stack trace. But the mini is also using IRQ triggers.

That's this error? https://github.com/justinweiss/bmi260/blob/main/bmi260_core.c#L747

Well, if it's a crash in the module it would be best if the module could recover without forcing the software to handle it

With hrtimer I wonder if it's trying to access the hardware / bus before it's ready. But that code isn't any different than the 160 IIRC so I'd expect the same problem there. Haven't heard of any problems with that one though.

I haven't been able to cause the problem on the Win Mini unfortunately, so there must be some difference. I was wondering if it was IRQ vs hrtimer triggers, but when I tried forcing hrtimer a while back I also don't remember seeing the problem. That's the first thing I'll try again once I have some time though.

easiest way to see if gyro is sending data is watch cat /sys/bus/iio/devices/iio\:device0/in_accel_x_raw (assuming device0 is right on the Win 4)
