I am writing a Linux user space application. Where I want to invoke registered callback function in user space area from the kernel space. Here the interrupt arriving on GPIO pin (For this event trigger I am using external button press) and registered function getting called in user space.
For your information I am using hardware is Jetson Xavier NX board running with linux OS (tegra-4.9) and GPIO9 AUDIO_MCLK connected to external switch (push button).
Is there any method is available to do this?
Thanks in advance for your response
