Function Documentation

int sceGeDrawSync (  int  syncType  )

Wait for drawing to complete. Parameters: syncType  - Specifies the condition to wait on. One of PspGeSyncType. Returns: ???

void* sceGeEdramGetAddr (  void   )

Get the address of VRAM. Returns: A pointer to the base of VRAM.

unsigned int sceGeEdramGetSize (  void   )

Get the size of VRAM. Returns: The size of VRAM (in bytes).

unsigned int sceGeGetCmd (  int  cmd  )

Retrive the current value of a GE command. Parameters: cmd  - The GE command register to retrieve. Returns: The value of the GE command.

int sceGeGetMtx (  int  type, void *  matrix )

Retrieve a matrix of the given type. Parameters: type  - One of PspGeMatrixTypes. matrix  - Pointer to a variable to store the matrix. Returns: ???

int sceGeListDeQueue (  int  qid  )

Cancel a queued or running list. Parameters: qid  - The ID of the queue. Returns: ???

int sceGeListEnQueue (  const void *  list, void *  stall, int  cbid, void *  arg )

Enqueue a display list at the tail of the GE display list queue. Parameters: list  - The head of the list to queue. stall  - The stall address. If NULL then no stall address set and the list is transferred immediately. cbid  - ID of the callback set by calling sceGeSetCallback arg  - Probably a parameter to the callbacks (to be confirmed) Returns: The ID of the queue.

int sceGeListEnQueueHead (  const void *  list, void *  stall, int  cbid, void *  arg )

Enqueue a display list at the head of the GE display list queue. Parameters: list  - The head of the list to queue. stall  - The stall address. If NULL then no stall address set and the list is transferred immediately. cbid  - ID of the callback set by calling sceGeSetCallback arg  - Probably a parameter to the callbacks (to be confirmed) Returns: The ID of the queue.

int sceGeListSync (  int  qid, int  syncType )

Wait for syncronisation of a list. Parameters: qid  - The queue ID of the list to sync. syncType  - Specifies the condition to wait on. One of PspGeSyncType. Returns: ???

int sceGeListUpdateStallAddr (  int  qid, void *  stall )

Update the stall address for the specified queue. Parameters: qid  - The ID of the queue. stall  - The stall address to update Returns: Unknown. Probably 0 if successful.
