Re: [gem5-users] can't run new disk image(Ubuntu 14.04.img) in gem5 X86 FS mode

[赵智慧]

Hello,

I have enabled devtmpfs in "Maintain a devtmpfs filesystem to mount at /dev" 
with the step of make menuconfig.

But it didn't work. FS mode still have the problem.

Hello,

Something like the above (this was taken from arch linux boot). The problem is 
that that the right devfs is not compiled into the kernel. You need to make 
sure that devtmpfs is enabled in your kernel.


You may have to recompile the kernel with devtmpfs enabled.

I see someone saying that this is not an error and will not affect the 
simulation. But like this,I can not get into the simulation system.

When I change the ubuntu-14.04.img to ubuntu-12.04.5.img,the m5term output like 
this:




mknod:extra operand '64'

Try 'mknod --help' for more information

mknod:extra operand '64'

Can anybody help me to slove the problem? It confused me for a long time. Thank 
you.

Thanks for your answer.
But which step can make sure the devtmpfs is enabled when compiling a kernel?

[gem5-users] can't run new disk image(Ubuntu 14.04.img) in gem5 X86 FS mode

hello, everyone

The default disk(linux-x86.img) can't support new version GLIBC(version 2.14) 
that my program needed.

So I create new disk image(ubuntu 14.04) to replace it, and I use the new 
kernel(x86-64_vmlinux_2.6.28.4).

But when I run gem5, the m5term output like this:
