Function Documentation

void VMCALL hycpu_flush_icache	(	struct HyPortLibrary *	portLibrary,
		void *	memoryPointer,
		UDATA	byteAmount
	)

CPU Control operations.

Flush the instruction cache to memory.

Parameters:

[in]	portLibrary	The port library
[in]	memoryPointer	The base address of memory to flush.
[in]	byteAmount	Number of bytes to flush.

void VMCALL hycpu_shutdown

(

struct HyPortLibrary *

portLibrary

)

PortLibrary shutdown.

This function is called during shutdown of the portLibrary. Any resources that were created by hycpu_startup should be destroyed here.

Parameters:

[in]

portLibrary

The port library

Note:

Most implementations will be empty.

I_32 VMCALL hycpu_startup

(

struct HyPortLibrary *

portLibrary

)

PortLibrary startup.

This function is called during startup of the portLibrary. Any resources that are required for the exit operations may be created here. All resources created here should be destroyed in hycpu_shutdown.

Parameters:

[in]

portLibrary

The port library

Returns:

0 on success, negative error code on failure. Error code values returned are

• HYPORT_ERROR_STARTUP_CPU

Note:

Most implementations will simply return success.
