I have a series of devices with GPIO controlled force feedback that this driver helps us control better. So I'm looking forward to this, thank you.
Thanks for testing. I didn't had much time recently and i was fighting with hr timer resolution stuff. But will try to send the next version in March.
Note that when I set the resolution too low (I got confused and set the period to 255) my device locked up hard and only a forced power cycle could bring it back.
Unfortunately this is a general design issue by driving the GPIO by a kernel driver and "expected" behavior. I didn't have a good solution for it yet. What period is too low without limiting other users? The only idea which comes to my mind is to introduce a kernel parameter for this driver to set a lower period limit. This can be provided by some administrator or system designer with enough experience. So a general user doesn't need to care about it. Best regards
