Name:Start of Monarch synchronization. This waits until all CPUs have* entered the exception handler and then determines if any of them* saw a fatal event that requires panic. Then it executes them* in the entry order.* TBD double check parallel CPU hotunplug
Proto:static int mce_start(int *no_way_out)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
int * | no_way_out |
960 | cpus = num_online_cpus() |
961 | timeout = monarch_timeout * NSEC_PER_USEC |
963 | If Not timeout Then Return -1 |
966 | atomic_add( * no_way_out, & global_nwo) |
979 | atomic_set( & global_nwo, 0) |
980 | Return -1 |
988 | smp_rmb() |
990 | If order == 1 Then |
995 | Else |
1003 | If Check if a timeout waiting for other CPUs happened. Then |
1005 | atomic_set( & global_nwo, 0) |
1006 | Return -1 |
1015 | no_way_out = atomic_read( & global_nwo) |
1017 | Return order |
Name | Describe |
---|---|
do_machine_check | The actual machine check handler. This only handles real* exceptions when something got corrupted coming in through int 18.* This is executed in NMI context not subject to normal locking rules. This* implies that most kernel services cannot be safely used |
