PWMs are used in a wide range of applications. Most in-kernel usages have only soft requirements regarding precision and switching behaviour (LEDs, fan control, backlight). However if you control a motor you might have higher demands that currently cannot be mapped generically using the current PWM API given the wide variance of hardware drivers and hardware limitations. In this talk Uwe presents his vision how the PWM framework can be changed to better match the needs for higher precision and better control of PWM devices. This includes: * faster and easier control from userspace * tighter rules for lowlevel drivers * a way to determine the best request for a given use case on a certain hardware * more general abstraction of the PWM waveform
