Re: [gem5-users] Linux boot

2020-02-27 Thread niranjan soundararajan
The issue with booting with KVM is resolved when only applying the second
patch.

The issue we now see is after logging in we get a "Login timeout after 60
seconds" before we could type the username and password. Has anyone run
into this issue?

Thanks

Thanks for getting back. But we need the full Ubuntu for running server
workloads.

We looked at this link:
https://www.mail-archive.com/gem5-users@gem5.org/msg15053.html

Where a user has gotten this resolved but when applying the 2 patches
doesnt help our case.

Any other options?

Thanks

With Ubuntu, I would use my own minimal init rather than the super
bloated Ubuntu one.

Then you can m5 checkpoint and restore as discussed elsewhere.

Thanks Abhishek. We get the following error with KVM

panic: KVM: Failed to enter virtualized mode (hw reason: 0x8021)


Any techniques to get over this error


Thanks

Re: [gem5-users] Linux boot

2020-02-26 Thread Abhishek Singh
Hi Yuan,

The way I simulate DerivO3CPU, (first run)is I run with AtomicSimpleCPU and
create a checkpoint after the boot by using command “/sbin/m5 checkpoint”
and then run the benchmark.

In my second run I restore checkpoint using AtomicSimpleCPU and then switch
to DerivO3CPU.

And then I get the final stats using DerivO3CPU.

Hi, Abhishek,

I also have similar questions. I can boot the ubuntu18.04 and kernel 5.2.3
with timingSimpleCPu and KVM, but I want to run simulation with
DeriveO3CPU. Do you know how to change the CPU to DeriveO3 after we boot
the system with kvm or timingsimple cou?

Best regards.

Yuan

Hi,

You can use KVM CPU, it will boot the system fast as it works on host
machine speed.
