AMD's Compute-GPU Model
A tutorial was held in conjunction with MICRO-48. We have made the slides available from our 2015 tutorial titled: The AMD gem5 APU Simulator: Modeling Heterogeneous Systems in gem5.

ARM's NoMali GPU Model
The NoMali GPU model models the interface used by ARM Mali GPUs. The model does not render or compute anything, but can be used to fake a GPU. This enables Android and ChromeOS experiments without software rendering which would otherwise make simulation results extremely misleading. It was presented in the 2015 gem5 User Workshop.
Getting started instructions are currently available for Android 4.4 (KitKat).
