Just to compare I tried to run Linux o= n QEMU emulating highbank.

For now I am unable to start in SMP mode. Only one core is activated.

And there is linux backtrace in L2C-310 init.

My command line:

# qemu-system-arm -smp 4 -M highbank -m 1024M -display none -no-reboot -kernel zImage -initrd rootfs.cpio.gz -dtb highbank.dtb -serial stdio

The kernel output:

Does SMP work with EL3 not enabled, or is this=
 a different bug?

If I set has_el3 to false, I can boot the 4 cores without problem. With
has_el3 set to true (default value) I am getting the above behavior (boot=
 OK
in uniprocessor mode, and misbehaving if -smp >=3D 2).

Odd. If you can point me to a test image I can use=
 to investigate
(preferably with System.map and commit hash of kernel used to build it)
I'll see if I can find time to have a look at what's going on there.

I put my test image at the following address:

http://dl.free.fr/rADch1Xnx<= /a>

You will get a tgz file with the following files in it:
  • imx6q-sabrelite.dtb
  • README
  • rootfs.cpio.gz
  • System.map=C2=A0
  • zImage
Instruction to run the image are in the README file.

The kernel is compiled using the imx_v6_v7_defconfig file (without modification) in the linux source tree

Thanks

JC
