void PosixThreadSupport::sendRequest ( uint32_t  uiCommand, ppu_address_t  uiArgument0, 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.

tell the task scheduler to use no more than numTasks tasks

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.
