# Use the common FSConfig to setup a Linux X86 System

  # Create specified number of CPUs. GPUFS really only needs one.

Matthew Poremba has uploaded this change for review. ( https://gem5-review.googlesource.com/c/public/gem5/+/69979?usp=email ) Change subject: configs: Allow other CPU types in GPUFS ...................................................................... configs: Allow other CPU types in GPUFS Previously the CPU type and memory modes were hardcoded for KVM, because there was a deadlock bug. After some recent testing, this deadlock bug no longer exists with the simple CPU models. Thus, changing the configs to allow for other CPU models as a first step toward lifting the KVM requirement from GPUFS.
