Updated by Alexander Kamkin over 4 years ago
- Priority changed from Normal to High
Updated by Alexander Kamkin over 4 years ago
- Status changed from New to Resolved
The problem is as follows:
L2.evictEntry()
L2.sendSnoopEvict()
L1.evictEntry()
(invalidate back)L1.sendSnoopEvict()
L2.writeEntry()
(write back)- redundant snoops causing infinite looping
