Hi Florian,

Yes, you’re right, there seems to be a bug, because cpu_number_map() and cpu_logical_map() are returning the same when BCM6358 starts with CMT 1:
[    4.662896] bcm6345_l1_irq_handle: smp_id=0 cpu_logical=1 cpu_number=1

Let’s see if I can fix it…

Best regards,
Álvaro.

Some BCM6358 devices start with Core #1 instead of Core #0.
Apart from that, SMP is restricted to 1 CPU since BCM6358 has a shared TLB,
which makes it impossible for the current SMP support to start both CPUs.

The problem is that smp_processor_id() returns 0 and then cpu_logical_map()
converts that to 1, which accesses an uninitialized position of intc->cpus[],
resulting in a kernel panic.

Sounds like you nee to correct the way the cpu_logical_map[] is
populated then?
