I'm working with imx6ull board. Currently, I'm developing a device driver for an SPI device.
In my driver, I'm using a GPIO interrupt. The interrupt is very fast and occurs at every 5ms. I would like to notify userspace application regarding this interrupt.
- Please suggest a suitable method for this type of notification(fast and efficient).
- Whether asynchronous notification is a good solution?
- Is there any way to enable or disable interrupts from userspace?
Thanks and Regrads
