Member Function Documentation

Memory& talvos::Device::getGlobalMemory ( )

inline

Get the global memory instance associated with this device.

Definition at line 42 of file Device.h.

PipelineExecutor& talvos::Device::getPipelineExecutor ( )

inline

Returns the PipelineExecutor for this device.

Definition at line 45 of file Device.h.

bool talvos::Device::isThreadSafe

(

)

const

Returns true if all of the loaded plugins are thread-safe.

Definition at line 132 of file Device.cpp.

void talvos::Device::notifyFenceSignaled

(

)

Notify the device that a fence was signaled.

Definition at line 140 of file Device.cpp.

void talvos::Device::reportError	(	const std::string &	Error,
		bool	Fatal = false
	)

Report an error that has occurred during emulation.

This prints Error to stderr along with the current execution context. If Fatal is true, abort() will be called after handling the error.

bool talvos::Device::waitForFences	(	const std::vector< const bool * > &	Fences,
		bool	WaitAll,
		uint64_t	Timeout
	)		const

Wait for fences to signal.

If WaitAll is true, waits for all fences to signal, otherwise waits for any single fence to signal. Returns true on success, or false if Timeout nanoseconds elapsed before the fences signaled.
