[gem5-users] Kernel panic when using ubuntu-18.04-arm64-docker.img

Hi all, Now I using the Latest linux kernel and disk images to run fs mode with KVM CPU (https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries), and I mount the image and modify the mnt-dir/init.gem5 to readfile from the –script, then I run this script, but after that, I ha

Hi, it looks like your script (/tmp/my_script) is exiting. I think the init process isn't supposed to exit. Gabe On Sun, Apr 11, 2021 at 4:13 AM kong han via gem5-users wrote: > Hi all, > > Now I using the Latest linux kernel and disk images to run fs mode with > KVM CPU ( > https://www.gem5.

[gem5-users] Add pio devices into Gem5 ruby network

Hi all : I need to construct a MPSoC system based on Gem5 FS mode. And I have chosen the Ruby Garnet Network with MESI_Three_Level protocol as the interconnect bus. Now I would like to add some pio devices into the network. In general, I expect cpu cores and devices can communicate with each o

[gem5-users] can't reset stats.txt when using KVM CPU

Hi all, Now I using the KVM CPU to run fs mode, and I try two ways to reset the m5out/stats.txt but all can’t work. 1) I use the m5.stats.reset() and m5.stats.dump() functions in the python script before switch cpu, the m5out/stats.txt will be written. But then I use m5.stats.reset() and m

[gem5-users] can anyboby tell me how to generate the checpoints of spec2017?

Hi, if you want to generate the checkpoint using the fs, you can use the m5.checkpoint() func in the python script, or can use the /sbin/m5 checkpoint agter you connect the m5term. ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe sen

Thanks a lot, I think my problem occurred after the /tmp/my_script run and before exec /sbin/getty -a root -L ttyAMA0 vt102 run. You say the init process isn’t supposed to exit, I counldn’t understand it, which is the init process? The /tmp/my_script, or the /init.gem5? and I want to know the re

[gem5-users] Long linkage

Hi, Why does the recent version of gem5 takes very long on the last step when creating the gem5.opt? My 2-month old repo is just fine, but the new version takes a very long to finish link. I tried on three different machines with the different OS but no improvement.

[gem5-users] Re: Long linkage

The opt build now uses link time optimization (LTO) and does not use partial linking. On slower machines and/or machines with fewer cores (and maybe less memory?) this seems to really slow things down, where on machines with more cores, LTO linking happens to be parallel where normal linking doesn'
