Perf list to FU740 HPM bindings question

As we all know, the default perf list are just a symbolic links to real PMU events.

I have ended up with following table of perf list to FU740 Events relations.

Perf name Linux enum Perf ID FU740 Name FU740 Id
branch-instructions OR branches PERF_COUNT_HW_BRANCH_INSTRUCTIONS 0x04 Conditional branch retired 0x4000
branch-misses PERF_COUNT_HW_BRANCH_MISSES 0x05 Branch direction misprediction Branch/jump target misprediction 0x2001 0x4001
bus-cycles PERF_COUNT_HW_BUS_CYCLES 0x06 N/A
cache-misses PERF_COUNT_HW_CACHE_MISSES 0x03 Instruction cache miss Data cache miss or memory-mapped I/O access 0x0102 0x0202
cache-references PERF_COUNT_HW_CACHE_REFERENCES 0x02 Instruction cache/ITIM busy Data cache/DTIM busy 0x0801 0x1001
cpu-cycles OR cycles PERF_COUNT_HW_CPU_CYCLES 0x00 mcycles 0x01
instructions PERF_COUNT_HW_INSTRUCTIONS 0x01 minstret 0x02
ref-cycles PERF_COUNT_HW_REF_CPU_CYCLES 0x09 N/A
stalled-cycles-backend OR idle-cycles-backend PERF_COUNT_HW_STALLED_CYCLES_FRONTEND 0x07
stalled-cycles-frontend OR idle-cycles-frontend PERF_COUNT_HW_STALLED_CYCLES_BACKEND 0x08

Please look at it if it seems correct, also i have a question about stalled cycles frontend/backend, in FU740 manual we have the following list:

Address-generation interlock
Long-latency interlock
CSR read interlock
Integer multiplication interlock
Floating-point interlock

What of above, if any, should go to stalled cycles? These doesn’t look like stalled cycles at all. Should stalled-cycles also be a N/A ?

Also adding general cache event bindings:

Perf name Linux enum Perf ID U740 Name U740 Id
L1-icache-loads-misses L1I_READ_ACCESS 0x10009 Instruction cache miss 0x0102
L1-dcache-load-misses L1D_READ_MISS 0x10001 Data cache miss or memory-mapped I/O access 0x0202
L1-dcache-stores L1D_WRITE_ACCESS 0x10002 Data cache write-back 0x0402
iTLB-load-misses ITLB_READ_MISS 0x10021 Instruction TLB miss 0x0802
dTLB-load-misses DTLB_READ_MISS 0x10019 Data TLB miss 0x1002
