Bring a new x86_64 device to Linux

[Agron Selimaj <as9902613@xxxxxxxxx>]

Hello,

I am making a GPIO driver for a custom x86_64 motherboard.

It came with a windows driver which is fairly simple but before
reading or witting to a certain GPIO pin I have to keep reading an
other ioport with inb() until GPIO data is ready.

However, I need to make sure this is the right motherboard so I am
reading a 10 byte string where the model information is located, but
just before I read the last byte the kernel is killing my kernel
module and marking it as tainted. Why would this happen?

I also noticed that detection and probing is now done using platform
drivers on ARM platform. I would like to follow the same on x86_64 but
I don't find any documentation/examples to help me.


The kernel version I am working on is 3.12.21
