From past work, we know the five counters required to compute the first level topdown metrics on Intel processors:

CLK_UNHALTED_CORE      = 0x00
IDQ_UOPS_NOT_DELIVERED_CORE = 0x9C, umask=1
UOPS_RETIRED_RETIRE_SLOTS   = 0xC2, umask=2
UOPS_ISSUED_ANY             = 0x0E, umask=1
INT_MISC_RECOVERY_CYCLES    = 0x0d, umask=3, cmask=1

These can be composed as follows

width = 4                                       ; issue width = 4 for many processors
total-slots = CLK_UNHALTED_CORE * width
frontend = IDQ_UOPS_NOT_DELIVERED_CORE / total-slots
retiring = UOPS_RETIRED_RETIRE_SLOTS / total-slots
speculation = (UOPS_ISSUED_ANY - UOPS_RETIRED_RETIRE_SLOTS + (width*INT_MISC_RECOVERY_CYCLES)/width
backend = 1 - (frontend + retiring + speculation)

Now working with the definitions from “perf-list” we can also find the set of performance counters used to compute topdown metrics on AMD. First here are the definitions that perf gives us:

PipelineL1:
  backend_bound
       [d_ratio(de_no_dispatch_per_slot.backend_stalls, total_dispatch_slots)]
  bad_speculation
       [d_ratio(de_src_op_disp.all - ex_ret_ops, total_dispatch_slots)]
  frontend_bound
       [d_ratio(de_no_dispatch_per_slot.no_ops_from_frontend,
        total_dispatch_slots)]
  retiring
       [d_ratio(ex_ret_ops, total_dispatch_slots)]
  smt_contention
       [d_ratio(de_no_dispatch_per_slot.smt_contention, total_dispatch_slots)]

This simplifies further

de_no_dispatch_per_slot.backend_stalls        = 0x1A, umask=0x1E
total_dispatch_slots                          = 6 * ls_not_halted_cyc
ls_not_halted_cyc                             = 0x76
de_src_op_disp.all                            = 0xAA, umask=0x7
ex_ret_ops                                    = 0xC1
de_no_dispatch_per_slots.no_ops_from_frontend = 0x1A0, umask=1
de_no_dispatch_per_slot.smt_contention        = 0x1A0, umask=0x60

So I believe we can compute top-down metrics using six counters listed above and then also have an additional category to account for pipeline slots not dispatched because of SMT contention.
