Function Documentation

◆ hipFuncSetAttribute()

hipError_t hipFuncSetAttribute	(	const void *	func,
		hipFuncAttribute	attr,
		int	value
	)

Set attribute for a specific function.

Parameters

[in]	func	Pointer of the function
[in]	attr	Attribute to set
[in]	value	Value to set

Returns

hipSuccess, hipErrorInvalidDeviceFunction, hipErrorInvalidValue

Note: AMD devices and some Nvidia GPUS do not support shared cache banking, and the hint is ignored on those architectures.

◆ hipFuncSetCacheConfig()

hipError_t hipFuncSetCacheConfig	(	const void *	func,
		hipFuncCache_t	config
	)

Set Cache configuration for a specific function.

Parameters

[in]

config

Configuration to set

Returns

hipSuccess, hipErrorNotInitialized Note: AMD devices and some Nvidia GPUS do not support reconfigurable cache. This hint is ignored on those architectures.

◆ hipFuncSetSharedMemConfig()

hipError_t hipFuncSetSharedMemConfig	(	const void *	func,
		hipSharedMemConfig	config
	)

Set shared memory configuation for a specific function.

Parameters

[in]	func	Pointer of the function
[in]	config	Configuration

Returns

hipSuccess, hipErrorInvalidDeviceFunction, hipErrorInvalidValue

Note: AMD devices and some Nvidia GPUS do not support shared cache banking, and the hint is ignored on those architectures.
