Hi Unfortunately I found another older example where my patch below did not work. In that one only cpu 0 where online but 0,1,2,3 where active. So maybe: return MAX(get_cpus_active(), get_highest_cpu_online()+1); might work better. Someone with better knowledge about this than I have should look at the problem.

From: Karlsson, Jan Hi I have seen a problem when it comes to the number of cpus for ARM (32-bits). static int arm_get_smp_cpus(void) { return MAX(get_cpus_active(), get_cpus_online()); } In one of my example, “help –k” gives me: cpu_possible_map: 0 1 2 3 cpu_present_map: 0 1 2 3 cpu_online_map: 0 3 cpu_active_map: 3 So the number of cpus will become 2. However there are code in a number of places that will then only accept cpu 0 and 1 as cpus to handle. When I changed to code to be the same as for ARM64 things worked as expected: static int arm_get_smp_cpus(void) { return MAX(get_cpus_online(), get_highest_cpu_online()+1); } Jan Jan Karlsson Senior Software Engineer System Assurance Sony Mobile Communications Tel: +46 703 062 174
