<div dir="ltr">Hi,<div><br></div><div>I want to run a program when DP monitor is plugged in/out.</div><div>My linux kernel ( 3.14.0-00348-gbfcbf45) gets an interrupt when DP cable is removed or inserted.</div><div>From the graphics driver interrupt handler I can differentiate the two events.</div>
<div><br></div><div>I want to run a user space program when this removal/insertion happens. What are the possible</div><div>ways to achieve this?</div><div><br></div><div>when I google for this I am seeing examples related to udev(How to run a script when a usb device is inserted/removed); but in my case it is not device insertion/removal. There is no need for a device creation when the DP monitor is plugged in/out(There is no device node available for me).</div>
<div>Basically I want to send this removal/insertion event from my kernel interrupt handler to </div><div>user space program.</div><div><br></div><div>Regards,</div><div>Arun C </div></div>
