[Qemu-devel] how to choose arm's type

[tang peilei]

in qemu's doc, i found it support some arm integrator/cp board and arm926e 
or arm1026e cpu.
but if i can choose to use arm926e cpu or arm1026e cpu ???

when i build a linux kernel image, i let it run on qemu, but i found it get 
the architecture ID is 113, and 113 defined in mach-types is 
murphy	ARCH_MEDALB      MEDALB	113

i do not know why it is 113, i expect it to be 
integrator	 ARCH_INTEGRATOR	INTEGRATOR	 21
or
cintegrator  ARCH_CINTEGRATOR	CINTEGRATOR  275

and in linux kernel config i can not found MEDALB.
this problem made my kernel image can not run in qemu.
it failed in arch/arm/kernel/head.S
bl	__lookup_machine_type
this function return fail.

who knows what is wrong .
or how to choose my machine type to integrator ???

Use the -cpu commandline option.

Check again. I think you'll find that qemu reports machine ID 0x113 (== 275) 
for the integrator/cp emulation.

thank you, you are right, with your help, my kernel image can run into 
function start_kernel. thank you very much.

but in start_kernel function in linux-2.6.16, the kernel panic when it 
calls console_init.
I do not know why, if i should config my console ?? and how to config it 
???
