From 6d90ccd7d6f03630106f78ec7d75666429e26e45 Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Wed, 15 Apr 2020 09:26:38 +0100 Subject: [PATCH] configs: Add an example workloads module This will be a collection of Workload types. At the moment we provide the following: * ArmBaremetal: modelling a simple baremetal workload * ArmTrustedFirmware: modelling the arm trusted firmware workload Change-Id: Ib46286c03a1c952f981b172c1ea6aa4a6668757e Signed-off-by: Giacomo Travaglini Reviewed-by: Ciro Santilli Reviewed-by: Nikos Nikoleris Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/27969 Tested-by: kokoro --- configs/example/arm/workloads.py | 85 ++++++++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) create mode 100644 configs/example/arm/workloads.py diff --git a/configs/example/arm/workloads.py b/configs/example/arm/workloads.py new file mode 100644 index 000000000..61e57f6a9 --- /dev/null +++ b/configs/example/arm/workloads.py @@ -0,0 +1,85 @@ +# Copyright (c) 2020 ARM Limited +# All rights reserved. +# +# The license below extends only to copyright in the software and shall +# not be construed as granting a license to any other intellectual +# property including but not limited to intellectual property relating +# to a hardware implementation of the functionality of the software +# licensed hereunder.
