However, due to the wrong count of stall_slot and stall_slot_frontend on neoverse-n2, the real stall_slot and real stall_slot_frontend need to subtract cpu_cycles, so correct the expression of topdown metrics. Reference from ARM neoverse-n2 errata notice [1], D117. Since neoverse-n2 does not yet support topdown L2, metricgroups such as Cache, TLB, Branch, InstructionsMix, and PEutilization will be added to further analysis of performance bottlenecks in the following patches.
