os_intr_dist_straywhen they can determine no reason for the interrupt to have occurred, that is, when MSOP_INTR_ATTACH was not called for this interrupt slot, and the function wishes to have the interrupt treated as an error. The core kernel will typically log this as a stray interrupt error for the particular CPU vector.
The value of
os_intr_dist_stray is guaranteed to remain constant
for the life of the PSM.
os_intr_dist_nopwhen there is no other interrupt distribution structure to be returned. In this case there is no action to be taken by the core kernel (besides checking for posted events from os_post_events).
The default topology will include resources for CG 0, CGID 0, CPU 0, CPU caches, memory detected by the bootstrap (below 4GB only), and standard I/O buses detected.
