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);
}
