Target Kernel Instance APIs

Detailed Description

Internal APIs for target kernel instance operations.

Data Structures
struct	tivx_target_kernel_instance_t

Functions
tivx_target_kernel_instance	ownTargetKernelInstanceGet (uint16_t target_kernel_index, vx_enum kernel_id)
	Given a target_kernel_index and kernel_id return the handle to target kernel. More...
tivx_target_kernel_instance	ownTargetKernelInstanceAlloc (vx_enum kernel_id, volatile char *kernel_name, vx_enum target_id)
	Create a target kernel instance for given kernel_id.
vx_status	ownTargetKernelInstanceFree (tivx_target_kernel_instance *target_kernel_instance)
	Free previously allocate target kernel instance.
uint32_t	ownTargetKernelInstanceGetIndex (tivx_target_kernel_instance target_kernel_instance)
	Get fast index key for a given target kernel instance.
vx_status	ownTargetKernelInstanceInit (void)
	Init Target Kernel Instance Module.
void	ownTargetKernelInstanceDeInit (void)
	De-Init Target Kernel Instance Module.
tivx_target_kernel	tivxTargetKernelInstanceGetKernel (tivx_target_kernel_instance target_kernel_instance)
	Get target kernel for a given target kernel instance.
static vx_bool	tivxFlagIsBitSet (uint32_t flag_var, uint32_t flag_val)
	Macro to check if flag is set, flag MUST be of bit type.
static void	tivxFlagBitSet (volatile uint32_t *flag_var, uint32_t flag_val)
	Macro to set flag value, flag MUST be of bit type.

ownTargetKernelInstanceGet()

tivx_target_kernel_instance ownTargetKernelInstanceGet	(	uint16_t	target_kernel_index,
		vx_enum	kernel_id
	)

Given a target_kernel_index and kernel_id return the handle to target kernel.

Target kernel handle is created during create phase. During run phase, this API is used to quickly get access to the target_kernel_handle given target_kernel_index key.

kernel_id is used to confirm the handle matches the required kernel.

NULL is return if target kernel handle is not found.
