Phoronix: Linux PWM Gains An Atomic Interface In Linux 4.7

The Linux Kernel's PWM (Pulse Width Modulation) interface now has an atomic API for those writing drivers for fans, LEDs, vibrators, and other supported devices...

Just curious, why would anyone want to write a driver for vibrator?

[Hi-Angel]

Ah, I see, that's probably the one in phones.

The panel of use is larger than phone ones also. I guess Raspberry Pi could be a good example too.
Also, Michael stated some uses of PWM, not obviously of what this addition would be used for.

because linux is everywhere!

Ever thought about phones or tablets....? If you like dildos, I'm not gonna judge. But they aren't the first thing to vibrate.

apart from the obvious smartphones/tablets and embedded devices in general angle,

there are all VR gear that would benefit from better control over vibrators, and I'm thinking about devices like this http://edition.cnn.com/2015/01/09/te...est/index.html

also this (that never realized) http://www.roadtovr.com/araig-kickst...rtual-reality/
Although of course the same tech can be used to make VR gear for simulating intercourse, and it would also sell pretty damn well even outside of the usual sex toy buyer circles.

PWM is used for things like stepper motor control. So, for positioning the head of your... uh, how to put it delicately... hard drive. Mmm, no, that sounds rude. It's used in robotics, like changing the angle of your mechanical device. Dang it. Anyway, Linux gets inserted into all kinds of things these days, things that bring hobbyists and professionals alike a great deal of pleasure, so enjoy the new interface.

cool now its easier to make home-made vibrators.

The fun part is, there are already IoT vibrators and sex toys with some embedded OS. Maybe Linux. Haven't tested.
