Hi all,
First, I compile the ARM_MOESI_hammer with the command line
scons build/ARM_MOESI_hammer/gem5.opt -j 7
Then I configure the full system according to the gem5-X Full System Manual.
The gem5-X is an extended version of gem5. In the configuring phase , it is
little difference with gem5. In some extend, I think the configuration is
easier.
Next I run the command line as following:
build/ARM_MOESI_hammer/gem5.opt --remote-gdb-port=0 configs/example/fs.py
--cpu-clock=1GHz --kernel=vmlinux --machine-type=VExpress_GEM5_V1
--dtb-file=/home/gem5/gem5/system/arm/dt/armv8_gem5_v1_1cpu.dtb
--disk-image=gem5_ubuntu16.img --caches --l2cache --l1i_size=32kB
--l1d_size=32kB --l2_size=1MB --l2_assoc=2 --mem-type=DDR4_2400_4x16
--mem-ranks=4 --mem-size=4GB --sys-clock=1600MHz
--ruby --network=garnet2.0 --cpu-type=O3CPU
But I encounter some strange issues:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "build/ARM_MESI_Three_Level/python/m5/main.py", line 457, in main
exec(filecode, scope)
File "configs/example/fs.py", line 308, in
(options, args) = parser.parse_args()
File "/usr/lib/python3.8/optparse.py", line 1371, in parse_args
values = self.get_default_values()
File "/usr/lib/python3.8/optparse.py", line 1316, in get_default_values
defaults[option.dest] = option.check_value(opt_str, default)
File "/usr/lib/python3.8/optparse.py", line 766, in check_value
return checker(self, opt, value)
File "/usr/lib/python3.8/optparse.py", line 440, in check_choice
raise OptionValueError(
optparse.OptionValueError: option --cpu-type: invalid choice: 'AtomicSimpleCPU'
(choose from 'O3_ARM_v7a_3', 'TimingSimpleCPU', 'ex5_big', 'DerivO3CPU',
'TraceCPU')
I find in the build_opts folder, the ARM_MOESI_hammer specifies the
CPU_MODELLS='TimingSimpleCPU, O3CPU',
so in the command line I specify the cpu-type=O3CPU
And I also try to change the cpu-type parameter as the options in the error
information, but it seems that my operation does not work.
To be honest, I did not understand what to happen and why. Or the gem5-X did
not support using ruby and garnet2.0 .
And how can I solve this problem?
If I use the ARM to replace the ARM_MOESI_hammer, the full system can work
normally.
But I need to add the ruby and network?
Are there any suggestions?
Thanks a lot!
Zhang Meng
