| |
Do need to set lapic mapping for them
in arch/x86/kernel/visws_quirks.c: we only have visws_find_smp_config() to set mp_lapic_addr to APIC_DEFAULT_PHYS_BASE visws_get_smp_config() is nop call. default_get_smp_config/check_physptr/smp_read_mpc is not called in the path. So smp_register_lapic_address() is not called, and lapic is not mapped.
in arch/x86/kernel/mpparse.c if mpf->feature1 != 0, it will go through contruct_default_ISA_mptable instead of check_phystr path, so smp_register_lapic_address is not called.
Those pathes all have smp_found_config set.
So need to remove !smp_found_config checking
