Hi,
I built an ALPHA-FS system and trying to start the full system simulation
with the cache memory module, Ruby. However, I am getting the following
error message complaining that the ALPHA system does not have dma
controller. Has anyone encountered this and know how to resolve the issue?
thanks in advance,

I have made changes that rectify the error. You would need to either
download the latest version of gem5, or else update your gem5 repository.
