There was a missing option (--buffers-size) used to set the mandatory queue size for the scalar controllers. This patch renames the option to be more clear, and adds it to the argument parser. Default of 128 taken from the implementation on the GCN staging branch Change-Id: I58b6b57be07498cdf6e39c0bb85982674ec4caa6 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/32676 Reviewed-by: Matt Sinclair <mattdsinclair@gmail.com> Maintainer: Anthony Gutierrez <anthony.gutierrez@amd.com> Tested-by: kokoro <noreply+kokoro@google.com>
