[gem5-users] Re: An error occurred in i8237 DMA controller when running CPU SPEC 2017 benchmarks

Hi Ayaz, Thanks very much for your help. Like you said, I recompiled gem5 with MESI_Two_Level and followed the instructions to compile the kernel 5.4. And I tried both master branch and develop branch. But none of them work on my laptop unfortunately. It always gets stuck at booting. The

Hi Jinpeng, First of all, you will have to recompile gem5 to use Ruby with MESI_Two_Level (the default protocol is MI_example): scons build/X86_MESI_Two_Level/gem5.opt --default=X86 PROTOCOL=MESI_Two_Level Secondly, I will suggest you to compile your kernel following the instructions here:

Hi Hoa, Thanks so much for your help! I just tested it and it worked perfectly. Another question is that based on your test here(http://www.gem5.org/documentation/benchmark_status/#spec-2017-tests ), gem5-20 along with

[gem5-users] Re: An error occurred in i8237 DMA controller when running CPU SPEC 2017 benchmarks

Hi Jinpeng, The error seems to cause by 'sysinfo', which is called by SPEC 2017 before it starts running a workload. SPEC 2017 documents how to turn it off here: https://www.spec.org/cpu2017/Docs/utility.html#sysinfo. Basically, the fix is to add this line: sysinfo_program = to the SPEC config

For the disk image, I think I did not follow the instruction exactly. Instead I created a disk image with ubuntu-18.04.2 and then I manually compiled and built CPU SPEC 2017. But I think there would not be any difference in the disk image. Thanks. Jinpeng > On Jul 17, 2020, at 12:25 PM, Jason

Hi Jason, Thanks for your prompt help. I exactly follow this instruction(https://gem5art.readthedocs.io/en/latest/tutorials/spec2017-tutorial.html ) to build kernel 4.19.83 and disk image ubuntu-18.04.2 and I am using

Hi Jinpeng, Thanks for pointing this out! I haven't personally seen this error before. We've been trying to test SPEC 2017 with gem5-20. Could you give more guest details (e.g., kernel, OS, benchmark, inputs) and simulator details (e.g., ISA, CPU model, memory system, cores, etc.) so we can try
