Description (last modified by )
The ia64 kernel needs to be able to handle TLB misses caused by processing IRQ pseudocode.
The kernel should search the global page hash table while not holding the address space mutex. If there is a hit, the mapping is inserted into TLB and the processing is successful. A miss in this situation is a reason to panic the system or, if running in the context of the pseudocode owner task, kill the current task.
