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

2020-07-17 Thread Hoa Nguyen via gem5-users 
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 file. The SPEC config file used in the tutorial is
/home/gem5/spec2017/config/myconfig.x86.cfg

Regards,
Hoa Nguyen

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

2020-07-17 Thread Jinpeng Miao via gem5-users 
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

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

2020-07-17 Thread Jinpeng Miao via gem5-users 
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 gem5-19. 
Benchmarks I have tested are: 505.mcf_r, 602.gcc_s, 641.leela_s, 644.nab_s, 
with size of test. I tried two cpu type: AtomicSimpleCPU, DerivO3CPU. All of 
different combinations show the same error.

The command I run:
build/X86/gem5.opt configs/example/fs.py --kernel=vmlinux-4.19.83 
--disk-image=/home/jinpeng/gem5_newFlag_new/full_system_images/disks/ubuntu-18.img
 --num-cpus=1 --mem-type=DDR4_2400_16x4 --mem-channels=8 --mem-size=16GB 
--l1d_size=32kB --l2_size=1MB --l2cache --caches 
--cpu-type=AtomicSimpleCPU(DerivO3CPU) --cpu-clock=2.9GHz --script=test.rcS

test.rcS contains commands to run benchmarks, as shown below:
#!/bin/bash
cd /cpuSpec2017
ls
source shrc
go config
runcpu --config=try1 --size=test --copies=1 --noreportable --iterations=1 
644.nab_s 

And the output at the VM terminal with unexpected termination:

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

2020-07-17 Thread Jason Lowe-Power via gem5-users 
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 to reproduce this
problem?

Hoa, have you seen this error before in any of our tests? Can you add a
Jira issue for this?

Here's the results from our tests with SPEC 2017, so far:
http://www.gem5.org/documentation/benchmark_status/#spec-2017-tests

You can find all of the details on how we ran these in the gem5-resources
repository:
https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/master/src/spec-2017/

Cheers,
Jason

Hello all,

I am trying to build and run CPU SPEC 2017 benchmarks in the FS mode, but
the process terminated unexpectedly with an error happening in i8237 DMA

what causes this bug and how to fix it. Any help would be really
appreciated. Thanks!

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

2020-07-17 Thread Jinpeng Miao via gem5-users 
Hello all,

I am trying to build and run CPU SPEC 2017 benchmarks in the FS mode, but the 
process terminated unexpectedly with an error happening in i8237 DMA 
controller. I did not change the source code. I do not quite understand what 
causes this bug and how to fix it. Any help would be really appreciated. Thanks!

Output as below:

[gem5-users] Adding new MessageSizeType in Coherence Protocol

2020-07-17 Thread VIPIN PATEL via gem5-users 
Hi All,

I am adding new MessageSizeType to src/mem/ruby/protocol/Ruby_Exports.sm
file in MessageSizeType enumeration.
During the execution of the gem5 binary,  a panic error with message
"Invalid range for type MessageSizeType " occurs at the start of execution.
Kindly point out the correct way to add a new MessageSizeType and any
checks need to be done while making such changes.

Regards,
