[Qemu-devel] How to run realview-pbx-a9 image in qemu

[Qemu-devel] How to run realview-pbx-a9 image in qemu

[Xiao Jiang]

Hello,

I downloaded latest qemu 0.14.1, it should support realview-pbx-a9 board 
now from
below cmd.
$ qemu-system-arm -M ?|grep Cortex-A9
realview-pbx-a9 ARM RealView Platform Baseboard Explore for Cortex-A9

Then I compiled a zImage from latest mainline with use 
realview-smp_defconfig as config
file, but unfortunately qemu can't run with the image, I had tried the 
below instructions.
1. qemu-system-arm -M realview-pbx-a9 -kernel zImage -initrd initrd.img 
-nographic -append "console=ttyAMA0"
2. qemu-system-arm -M realview-pbx-a9 -m 1024M -kernel zImage -nographic 
-append "root=/dev/nfs nfsroot=128.225.160.22:/home/work/rootfs rw 
console=ttyAMA0 rdinit=/sbin/init" -net nic -net tap,ifname=tap0,script=no
Both instructions can't work, console is hang and no informations is 
appeared.
so I am wondering if there are something wrong about the kernel, am I 
choose the wrong
config file for realview-pbx-a9 board? Or the native mainline kernel 
can't boot on
qemu? Any suggestions? Thanks a lot!

Regards,
Xiao

The command I use is:

sudo ./arm-softmmu/qemu-system-arm -M realview-pbx-a9 -m 1024 -kernel
thekernel -serial telnet::4444,server -append "console=earlycon
console=ttyS0 console=ttyAMA0 earlyprintk root=/dev/nfs
nfsroot=10.1.1.1:/armroot rw
ip=10.1.1.2:10.1.1.1:10.1.1.1:255.255.255.0:armqemu nfsrootdebug "
-net nic -net tap,ifname=tap0,script=no,downscript=no

and then telnet to port 4444 to get the console.

(I'm using the linaro qemu tree).

Hi Dave,

It looks like I am not in luck, qemu still can't run successfully.
I recompiled the qemu from linaro qemu tree and executed below
instructions in order.

1. open window A, run below cmd.
xjiang@xjiang-desktop:~/work/qemu$ sudo qemu-system-arm -M 
realview-pbx-a9 -m 1024 -kernel zImage-cortex-a9 -serial 
telnet::4444,server -append "console=earlycon console=ttyS0 
console=ttyAMA0 earlyprintk root=/dev/nfs 
nfsroot=10.1.6.6:/home/gjiang/work/ti_sitara_am35xx-standard-glibc_std 
ip=10.1.6.8:10.1.6.6:10.1.6.1:255.255.255.0" -net nic,vlan=0 -net 
tap,vlan=0,ifname=tap0,script=no,downscript=no
QEMU waiting for connection on: telnet:0.0.0.0:4444,server

2. open another window B, telnet to port 4444.
xjiang@xjiang-desktop$ telnet localhost 4444
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

3, Then in window A, "VNC server running on `127.0.0.1:5901'" is appeared,
so I open terminal service client, set the computer name to 127.0.0.1:5901
and selected vnc protocol. But after I clicked connect I can't see any 
infos,
and the window named as "TightVNC: QEMU" is totally black.

Are there something wrong in above instructions? or there are other 
necessary
cmds which I have missed? Thanks in advance!

Xiao

I think you have a bad kernel image.
There are some prebuilt ones (and config files) linked off:

http://www.arm.com/community/software-enablement/linux.php

but unfortunately the webserver that holds them isn't happy today.

Hi Dave,

Thanks for the link, the server is unhappy :(.
I compiled this image from mainline ..., so to support qemu,
there should be some modifications in linux kernel, maybe I
should try kernel tree from linaro.
But fortunately, I can run vexpress-a9 image in linaro qemu
successfully this afternoon which is also built from mainline, :)

Xiao

Would you mind to let me know which configs you use to compile for a9
running on qemu?

Kernel configs?  I mostly use prebuilt kernels from the Linaro images.

Doesn't qemu emulate any default confis in arm, such as realview_defconfig?
(as far as I know, qemu can emulate malta in mips configs)

So that mean qemu can emulate Linaro soc board?

Thanks for your help,

IIRC, vexpress_defconfig works well with linaro qemu.
