From: Andreas Sandberg Date: Tue, 4 Jul 2017 10:12:24 +0000 (+0100) Subject: config: Discover CPU timing models based on target ISA X-Git-Tag: v19.0.0.0~2667 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dcb9334b94d14ccdc4ce42e1082e53d6d600e570;p=gem5.git config: Discover CPU timing models based on target ISA The CpuConfig helper currently assumes that all timing models live in the cores.arm package. This ignores the potential mismatch between the target ISA and the ISA assumptions made by the timing models. Instead of unconditionally listing all CPU models in cores.arm, list timing models from cores.generic and cores.${TARGET_ISA}. This ensures that the listed timing models support the ISA that gem5 is targeting.
