Hi,
do we (I) have edit permissions on the tutorial documentation?
I tried to follow the first steps of the tutorial, and the instructions are
out of date for the develop head. Some googling resulted in the solution,
but for me it still does not execute correctly.
It looks like there are Jira
The proposed patch fixes the issue.
My long runs now pass again.

Hi,
I am back to testing on an arm SBC.
Does anyone know the recipe for a successful build on an arm box?
GCC9 and clang 10 builds both die with obscure internal compiler errors.
This is on an ubuntu 20.04 setup, compiling the develop branch.

Hi,
I posted a jira issue on this but there has been no updates.

x86 linux boot is a component of the '--length long' regression.
You need the kernel and disk image that are installed when the regression
is run.
command line:
./build/X86/gem5.opt ./tests/gem5/x86-boot-tests/run_exit.py --kernel
boot-test/vmlinux-4.19.83 --disk boot-test/base.img --cpu-type
Do we still support python2.7?
I am adding some functionality and it is cleanest in python3, but the code
will fail if running in python2.
thanks

Do I post it as a separate review-board item?

I am running a set of checkpointed samples via the new simpoint patch.
it seems that when the simulation ends at the end of the sample, gem5
returns a non-zero code (127 I think).
Is this intended?
when gem5 reaches the end of the program via exit() it returns 0.
I have verified that x86 kvm works fine on AMD platforms, but fails on
Intel platforms.
Any hints about how to narrow down the cause (other than diving into gdb,
which I will do).
I am not an expert in KVM or how gem5 hooks up to libkvm.
