Four adapters need to produce data to a descriptor queue which is consumed by a user process. A lock mechanism was implemented to sync the adapters. However, this causes a performance hit. Is it possible to use CMPXCHG on Intel's i-386 to avoid the locking? Where can I find some doc and some sample code?
Thx
