atomic()

template<class T >

T gem5::LdsChunk::atomic ( const uint32_t index, AtomicOpFunctorPtr amoOp )

inline

an atomic operation

Atomics that are outside the bounds of the LDS chunk allocated to this WG are dropped.

a read operation

For reads that are outside the bounds of the LDS chunk allocated to this WG we return 0.
