#112 CONFIG_NR_CPU=8

[alex39x]

Interesting:
why in the config kernel Bering-5.10.config-x86_64?
...
CONFIG_NR_CPUS=8
...

I have a CPU of 16 core and i see only 8 cpu in x86_64 LEAF

dmesg:
...
[ 0.038380] APIC: NR_CPUS/possible_cpus limit of 8 reached. Processor 8/0x10 ignored.
...

I build x86_64 kernel wich CONFIG_NR_CPUS=64 and all ok.
It's not difficult. it is interesting but why CONFIG_NR_CPUS=8 ?

Probably sounded like a reasonable limit then.
