uint32_t  uiArgument1 
) [virtual]

send messages to SPUs

gMidphaseSPU.sendRequest(CMD_GATHER_AND_PROCESS_PAIRLIST, (uint32_t) &taskDesc);

we should spawn an SPU task here, and in 'waitForResponse' it should wait for response of the (one of) the first tasks that finished

not implemented

Implements btThreadSupportInterface.

Definition at line 124 of file PosixThreadSupport.cpp.

virtual void PosixThreadSupport::setNumTasks ( int  numTasks  )  [inline, virtual]

tell the task scheduler to use no more than numTasks tasks

Implements btThreadSupportInterface.

Definition at line 120 of file PosixThreadSupport.h.

void PosixThreadSupport::startSPU (  )  [virtual]

start the spus (can be called at the beginning of each frame, to make sure that the right SPU program is loaded)

Implements btThreadSupportInterface.

void PosixThreadSupport::waitForResponse ( unsigned int *  puiArgument0,
unsigned int *  puiArgument1 
) [virtual]

check for messages from SPUs

We should wait for (one of) the first tasks to finish (or other SPU messages), and report its response

A possible response can be 'yes, SPU handled it', or 'no, please do a PPU fallback'

Implements btThreadSupportInterface.
