Okay, I've partly implemented my event queue idea. Initial results are promising: the system still works, and I have been able to (slightly) improve the responsiveness when BASIC program "Sleep" is running. I haven't yet modified the nanosleep() call to make it queue-aware, so this improvement was a little unexpected!
I wonder if anyone can help with the following questions. What is the purpose of "mousehack"? As far as I can tell, it seems to bypass interrupts (in keyboard.c:pollmouse()), and instead implements a SWI (in keyboard.c:getosmouse()). Why? Another question: in pollmouse(), the line "if (model) return;" can be found. As far as I can tell from grepping the sources, "model" is set to 0 if emulating an ARM7500, so why do we have special treatment for ARM7500s? I found I got quite good results by initialising mousehackon to 0 in rpc-linux.c:main(), and commenting out the test of model, but randomly commenting out code makes me a little nervous! I'd be grateful if anyone can answer these questions.
