@alexgleason most of my kernel development has been with the Chromebooks. I've made a few patches for supporting the trackpads, touch screens and keyboard backlights on the chromebooks
@coolstar How do you figure out how to interface with IO hardware and convert what you find into software? I feel like that's the main thing blocking me from doing what I want. Any advice appreciated :)
@alexgleason the hardware I've interfaced with are PCI and I2C. For I2C, it's a simple 2 wire bus to the I2C device, so you just write some registers, and then read them as you get interrupts over GPIO.
For PCI, you need to query the OS for the memory, I/O port and interrupt resources. Then simply read/write as you get interrupts :)
@alexgleason since you're developing drivers for Linux, the Linux kernel handles the resource management for you. I'd suggest taking a look at some of the drivers in the kernel related to the device type you're working with
