M.E. Lоck Yоu hаve designed а bus-bаsed custоm non-cache-coherent shared memory DSP (Digital Signal Processor). Each CPU in the DSP has a private cache. The hardware provides the following primitives for the interaction between the private cache of a CPU and the shared memory: fetch(addr): Pulls the latest value from main memory into the cache flush(addr): Pushes the value at addr in the cache to main memory; it does not evict it from the cache hold(addr): Locks the memory bus for addr; no other core can fetch or flush this address until released unhold(addr): Releases the lock on addr You got this generic implementation for a ticket lock algorithm and tried it on your architecture. It did not work. struct ticket_lock { int next_ticket; // The next ticket number to give out int now_serving; // The ticket number currently allowed to enter}; void lock(struct ticket_lock *l) { // Acquire ticket int my_ticket = l->next_ticket++; // Wait for turn while (l->now_serving != my_ticket) { // Spin }} void unlock(struct ticket_lock *l) { l->now_serving++; // Release} a) [1 point] Identify any one potential flaw in the lock function when implemented on your architecture.
