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. > El 22 feb 2021, a las 22:00, Florian Fainelli <[email protected]> escribió: > > > > On 2/22/2021 12:13 PM, Álvaro Fernández Rojas wrote: >> 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? > -- > Florian
