Hi Vincent,
I compiled the linux-linaro-3.0 kernel and checked the content of /sys/devices/system/cpu/cpu[0-1]/topology/physical_package_id and found it is equal to '-1'.
Is it the expected value ?
Thanks

Was this on a OMAP3 device? Not sure whether MPIDR register is defined on Cortex-A8...

Oh, sorry. I forgot to mention it is on a pandaboard.

Hi,
You should see the mpidr values in the kernel log when the cpus are registered. Something like: CPU0: thread -1, cpu 0, socket xx, mpidr yyyyyy
Could you give me these values ?
Vincent

Stupid me, the mpidr was not displayed and I thought I had to enable early_printk but at this point I figured out sched_mc was not enabled in the config :/
So never mind and sorry for the noise :)
Thanks -- Daniel
ps: I was puzzled by the existence of the different topology files, does it make sense to show a file if the content is always invalid ?
