ChunkGenerator()

gem5::ChunkGenerator::ChunkGenerator ( Addr _startAddr, Addr totalSize, Addr _chunkSize )

inline

Constructor.

Parameters

_startAddr	The starting address of the region.
totalSize	The total size of the region.
_chunkSize	The size/alignment of chunks into which the region should be decomposed.

Definition at line 87 of file chunk_generator.hh.

complete()

Addr gem5::ChunkGenerator::complete ( ) const

inline

Number of bytes we have already chunked up.

done()

bool gem5::ChunkGenerator::done ( ) const

inline

Are we done?

That is, did the last call to next() advance past the end of the region?

Returns

True if yes, false if more to go.

last()

bool gem5::ChunkGenerator::last ( ) const

Is this the last chunk?

Returns

next()

bool gem5::ChunkGenerator::next ( )

inline

Advance generator to next chunk.

Returns

True if successful, false if unsuccessful (because we were at the last chunk).

setNext()

void gem5::ChunkGenerator::setNext ( Addr next )
