I second Gabe's suggestion. I think the IDE controller is a good starting point
since it mostly models the controller and passes more complicated (device
specific) functions to the disks.
I mostly templated based on the IDE controller when we started adding a PCI
interface for GPU (see WIP here:
https://gem5-review.googlesource.com/c/amd/gem5/+/23485).
Best,

The VirtIO device would be a pretty good example, although it does some unusual
things as far as determining how big it's BARs are supposed to be. The IDE
controller is a pretty simple device that's a little more representative in
that way. A lot of the complexity is in the actual disks themselves, with the
controller mostly just directing messages from the host to a particular disk.

Hi,
I’d recommend having a look at the VirtIO device….
(I don’t know if there are better examples, more experienced people are welcome
to chime in)
