Hi Tayyar,
Try: http://www.gem5.org/dist/current/arm/vmlinux-emm-pcie-3.3.tar.bz2
This contains a configuration file that should just work with gem5 (from:
http://www.m5sim.org/Download). They are for a 3.3 kernel, but at least they
should give you information about what you might be missing in your kernel
configuration.
What kind of configuration are you trying to run? What does your address map
look like? Is that similar to the addresses in your (simulated) system?
Let me know how it goes.
Regards,
René

Subject: [gem5-users] Compiling linux kernel for gem5 ARM
Hello All,
I am trying to simulate two processes communicating through a pty-tty pair in
gem5. I have a functional code that works on an off the shelf ARM-based SoC
that is running linux 3.7 ubuntu. But it doesn't work on gem5 with the default
kernel (I am suspecting the pty-tty drivers are missing in the default kernel).
I have tried using the same vmlinux kernel image to boot up in gem5, but the
simulator wouldn't boot up. When I observe in m5term, there is no activity. I
tried accessing http://www.m5sim.org/dist/current/arm/config-arm, to compare my
kernel config file with the gem5 defaults, but that page doesn't exist anymore.
I can provide my config file if that is of any help. I would really appreciate
any help with:
1. Locating the gem5 ARM default config file
2. Hints on compiling linux for gem5 ARM with pty-tty support
3. Any other ideas that can help resolve this issue
Thanks,
Tayyar
