函数名称:duce the number of lines printed when booting a large cpu count system
函数原型:static void announce_cpu(int cpu, int apicid)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
int | cpu | |
int | apicid |
896 | current_node等于NUMA_NO_NODE |
897 | node等于取得CPU的NUMA节点 |
900 | 如果非width则width等于num_digits(num_possible_cpus())加1 |
903 | 如果非node_width则node_width等于num_digits(num_possible_nodes())加1 |
906 | 如果cpu恒等于1则printk(formational "x86: Booting SMP configuration:\n") |
910 | 如果node不等于current_node则 |
911 | 如果current_node大于负1则打印标准信息("\n") |
913 | current_node等于node |
915 | printk(formational ".... node %*s#%d, CPUs: ", node_width - num_digits(node), " ", node) |
923 | 打印标准信息("%*s#%d", width - num_digits(cpu), " ", cpu) |
名称 | 描述 |
---|---|
do_boot_cpu | NOTE - on most systems this is a PHYSICAL apic ID, but on multiquad* (ie clustered apic addressing mode), this is a LOGICAL apic ID.* Returns zero if CPU booted OK, else error code from* ->wakeup_secondary_cpu. |
