PDF-QUESTION Why do we need to enable interrupts inside the loop in Acqui

disable interrupts Must finish put on queue of threads waiting for lock set guard to 0 call switch enable interrupts else value BUSY guard 0 LockRelease Why disable interrupts N. In the last 64257ve decades electron microscopy EM helped to reveal basic cell structures in great detail allowing research ers to visualize internal structure at resolutions that were about 100 times better than that ob tained by optical microscopy An Integrated Approach to Architecture and Operating Systems.
