sysu-arch's Issues

在Gem5上跑sieve时报错Syscall 334 out of range

执行命令:build/X86/gem5.opt configs/example/se.py --cmd=tests/test-progs/hello/bin/x86/linux/sieve --cpu-type=TimingSimpleCPU --l1d_size=64MB --l1i_size=16MB --caches

报错信息:build/X86/sim/syscall_emul.cc:74: warn: ignoring syscall set_robust_list(...)
build/X86/sim/syscall_desc.hh:209: fatal: Syscall 334 out of range

解决方法:

按助教所提供的链接 https://askubuntu.com/questions/1427882/syscall-issues-compiling-x86-c-code-for-gem5-using-ubuntu-22-04

lab1 build and simulate 修改cpu model

根据教程找到了X86CPU.py,并且仿照该文件写了以下语句

//隐藏代码

但是在仿真运行的时候提示
se.py: error: argument --cpu-type: invalid choice: 'X86MinorCPU' (choose from 'AtomicSimpleCPU', 'BaseAtomicSimpleCPU', 'BaseMinorCPU', 'BaseNonCachingSimpleCPU', 'BaseO3CPU', 'BaseTimingSimpleCPU', 'DerivO3CPU', 'NonCachingSimpleCPU', 'O3CPU', 'TimingSimpleCPU', 'TraceCPU', 'X86AtomicSimpleCPU', 'X86KvmCPU', 'X86NonCachingSimpleCPU', 'X86O3CPU', 'X86TimingSimpleCPU')

在备选项里没有出现minorcpu,搜索后也没有找到如何更改CPU模式的方法

LAB1 Familliar with gem5 中的 Malloc and Free LAB 实验在执行前需要重新编译 gem5

LAB1 Familliar with gem5 中的 Malloc and Free LAB 实验在执行前需要重新编译 gem5

问题

我按照教程操作,到了执行的时候报错称无效的 debug 标志“MemAlloc”:

$ ~/gem5/build/X86/gem5.opt --debug-flags=MemAlloc ./SYSU-ARCH/assets/LAB1/arch-sysu/MemAlloc.py
gem5 Simulator System.  https://www.gem5.org     
gem5 is copyrighted software; use the --copyright option for details.

gem5 version 22.0.0.2
gem5 compiled Oct 22 2022 00:39:20
gem5 started Oct 22 2022 10:57:51
gem5 executing on OnewayPC, pid 20319
command line: /home/oneway/gem5/build/X86/gem5.opt --debug-flags=MemAlloc ./SYSU-ARCH/assets/LAB1/arch-sysu/MemAlloc.py

invalid debug flag 'MemAlloc'

解决

查阅 官方教程 得知创建 SimObject 需要重新编译 gem5,重新编译之后再执行就好了。

建议

在实验文档中加上重新编译这一步。另外,建议加入提示,编译 gem5 时可加入参数 -j<cores+1> 加快编译速度。

lab 1 Memalloc an Free

在添加MemFreeReq类后重新编译gem5后尝试运行,终端报错如下:
AttributeError: Attribute reference on bound proxy (Parent.eventq_index.getValue)
似乎在m5实例化时出了问题,网上也没有相关描述

Lab 6 的 Build ACCEL-SIM 部分建议加入一些解释

在执行以下两条指令时
source ./gpu-simulator/setup_environment.sh
make -j -C ./gpu-simulator/
可能会出现类似于

nvcc fatal : Unsupported gpu architecture 'compute_10'

等看起来是错误的信息
但根据链接 以上错误是正常的 可以通过在指令中加入 -i 消除这些报错
