Metrics for Integrity Servers
FLITLB_MISS | Demand fetch missed in the L1 or first level instruction TLB |
| (FLITLB) and caused an IPC lookup. |
MLITLB_MISS | L2 or |
FLI_READ.DMND | FLI demand fetch reads. |
IA64_INST_RETIRED | Number of retired |
| predicated on and predicated off instructions and nops, |
| and excludes |
MLITLB_HPW_ABORTS | MLI TLB hardware |
CYC_BE_BUBBLE.ANY | Number of cycles lost to replays, flushes or stalls, including |
| partial replay cycles. |
CPU_OP_CYCLES.ALL | Number of elapsed CPU operating cycles. |
CYC_BE_IBD_STALL.ANY | Number of cycles lost to backend IBD bubbles for any |
| reason. |
CYC_BE_IBD_STALL.FEBUB | Number of backend bubbles due to FE bubbles - the |
| instruction fetch engine has not provided anything to issue. |
