Is there a way to make OpenBIOS not use so much CPU time when running in QEMU? My laptop becomes very hot when I do anything in OpenBIOS.
I've noticed that too. The input device (keyboard/serial) is scanned in a tight busy loop. With some effort, this could be changed to interrupt driven.
But the same thing happens also when lots of Forth is executed, maybe the Forth interpreter and QEMU code fits in the CPU cache nicely and this then maximizes CPU throughput and power consumption.
