Detailed Description

RSX library.

This library contains the necessary functions for handling the RSX, the accelerated 3D chip of the PS3.

Function Documentation

rsxAddressToOffset()

static s32 rsxAddressToOffset ( void *  ptr, u32 *  offset  )

inlinestatic

Converts a pointer value in RSX memory to an offset.

Parameters

ptr	The pointer whose value is to be converted.
offset	A pointer to the returned offset value.

Returns

zero if no error occured, nonzero otherwise.

rsxFlushBuffer()

void rsxFlushBuffer

(

gcmContextData *

context

)

Flushes the RSX command buffer.

This ensures all remaining commands in the command buffer are executed, and that the buffer is empty when that function returns.

Parameters

context

Pointer to the context object.

rsxInit()

gcmContextData* rsxInit	(	const u32	cmdSize,
		const u32	ioSize,
		const void *	ioAddress
	)

Initialize the RSX context and the RSX memory manager.

The user must provide a 1 MB-aligned IO buffer allocated in main memory, which size is a multiple of 1 megabyte.

This function initializes a heap structure in RSX memory space, allowing dynamic memory allocation using rsxMalloc, rsxMemalign and rsxFree.

Parameters

cmdSize	The command buffer size.
ioSize	The allocated IO buffer size.
ioAddress	Pointer to an allocated buffer of ioSize bytes.

Returns

Pointer to the allocated context structure.

rsxResetCommandBuffer()

void rsxResetCommandBuffer

(

gcmContextData *

context

)

Reset the RSX command buffer.

Parameters

context

Pointer to the context object.
