函数名称: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.
函数原型:static int do_boot_cpu(int apicid, int cpu, struct task_struct *idle, int *cpu0_nmi_registered)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
int | apicid | |
int | cpu | |
struct task_struct * | idle | |
int * | cpu0_nmi_registered |
