From: Bobby R. Bruce Date: Wed, 19 Aug 2020 07:32:16 +0000 (-0700) Subject: tests: Removed m5threads tests from .testignore X-Git-Tag: v20.1.0.0~258 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1009c9878ce0ba386fe1a87cf33c8bfad05b3b8c;p=gem5.git tests: Removed m5threads tests from .testignore This commit fixes many problems which were resulting in these tests not executing correctly. However, the m5thread tests are still failing with an `fatal:syscall set_tid_address (#166) unimplemented` error, recorded here: https://gem5.atlassian.net/browse/GEM5-747. The tests have been removed from .testignore as part of our goal of removing all tests from the .testignore file: https://gem5.atlassian.net/browse/GEM5-361 Change-Id: I287d1e126963114a791d7f3aa563a037a89b2cb7 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/32916 Reviewed-by: Jason Lowe-Power Maintainer: Jason Lowe-Power Tested-by: kokoro --- diff --git a/tests/gem5/.testignore b/tests/gem5/.testignore index ace6a5d72..81c0401cf 100644 --- a/tests/gem5/.testignore +++ b/tests/gem5/.testignore @@ -59,17 +59,5 @@ test-insttest-rv64i-linux-TimingSimpleCPU-RISCV-aarch64-fast test-insttest-rv64i-linux-DerivO3CPU-RISCV-aarch64-fast test-insttest-linux-AtomicSimpleCPU-SPARC-aarch64-fast test-insttest-linux-TimingSimpleCPU-SPARC-aarch64-fast -test-atomic-DerivO3CPU-SPARC-x86_64-opt -test-atomic-TimingSimpleCPU-SPARC-x86_64-opt -test-atomic-DerivO3CPU-SPARC-x86_64-debug -test-atomic-TimingSimpleCPU-SPARC-x86_64-debug -test-atomic-DerivO3CPU-SPARC-x86_64-fast -test-atomic-TimingSimpleCPU-SPARC-x86_64-fast -test-atomic-DerivO3CPU-SPARC-aarch64-opt -test-atomic-TimingSimpleCPU-SPARC-aarch64-opt -test-atomic-DerivO3CPU-SPARC-aarch64-debug -test-atomic-TimingSimpleCPU-SPARC-aarch64-debug -test-atomic-DerivO3CPU-SPARC-aarch64-fast -test-atomic-TimingSimpleCPU-SPARC-aarch64-fast realview-o3-checker-ARM-x86_64-opt realview64-o3-checker-ARM-x86_64-opt diff --git a/tests/gem5/m5threads_test_atomic/atomic_system.py b/tests/gem5/m5threads_test_atomic/atomic_system.py index 2f4ae8ed7..2d9b12937 100644 --- a/tests/gem5/m5threads_test_atomic/atomic_system.py +++ b/tests/gem5/m5threads_test_atomic/atomic_system.py @@ -26,6 +26,7 @@ import m5 from m5.objects import * +from caches import * import sys import argparse @@ -43,6 +44,7 @@ root.system.clk_domain = SrcClockDomain() root.system.clk_domain.clock = '3GHz' root.system.clk_domain.voltage_domain = VoltageDomain() root.system.mem_mode = 'timing' +root.system.mem_ranges = [AddrRange('512MB')] if args.cpu_type == 'DerivO3CPU': root.system.cpu = [DerivO3CPU(cpu_id = i) @@ -54,11 +56,45 @@ else: print("ERROR: CPU Type '" + args.cpu_type + "' not supported") sys.exit(1) +root.system.membus = SystemXBar() +root.system.membus.badaddr_responder = BadAddr() +root.system.membus.default = root.system.membus.badaddr_responder.pio + +root.system.system_port = root.system.membus.slave + process = Process(executable = args.cmd, cmd = [args.cmd, str(args.num_cores)]) -for i in range(int(args.num_cores)): - root.system.cpu[i].workload = process +for cpu in root.system.cpu: + cpu.workload = process + cpu.createThreads() + cpu.createInterruptController() + + # Create a memory bus, a coherent crossbar, in this case + cpu.l2bus = L2XBar() + + # Create an L1 instruction and data cache + cpu.icache = L1ICache() + cpu.dcache = L1DCache() + + # Connect the instruction and data caches to the CPU + cpu.icache.connectCPU(cpu) + cpu.dcache.connectCPU(cpu) + + # Hook the CPU ports up to the l2bus + cpu.icache.connectBus(cpu.l2bus) + cpu.dcache.connectBus(cpu.l2bus) + + # Create an L2 cache and connect it to the l2bus + cpu.l2cache = L2Cache() + cpu.l2cache.connectCPUSideBus(cpu.l2bus) + + # Connect the L2 cache to the L3 bus + cpu.l2cache.connectMemSideBus(root.system.membus) + +root.system.mem_ctrl = DDR3_1600_8x8() +root.system.mem_ctrl.range = root.system.mem_ranges[0] +root.system.mem_ctrl.port = root.system.membus.master m5.instantiate() exit_event = m5.simulate() diff --git a/tests/gem5/m5threads_test_atomic/caches.py b/tests/gem5/m5threads_test_atomic/caches.py new file mode 100755 index 000000000..d2d9e62c9 --- /dev/null +++ b/tests/gem5/m5threads_test_atomic/caches.py @@ -0,0 +1,112 @@ +# Copyright (c) 2016 Jason Lowe-Power +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions are +# met: redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer; +# redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution; +# neither the name of the copyright holders nor the names of its +# contributors may be used to endorse or promote products derived from +# this software without specific prior written permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.
