Topic hijack...
I also need to investigate the possiblitiy of a low level/low latency wait for hardware interrupt that may be generated by my graphics card on completion of a rendering operation.
I know I can (assuming I know exactly which interrupt to use) send the task to sleep and then use an interrupt handler to signal it when the time comes, but is there a lower latency way?
Anybody had any real experience with this kind of thing?
