Add PMU events for AMD Zen3 processors as documented in the AMD Processor
Programming Reference for Family 19h and Model 01h [1].
Below are the events which are new on Zen3:
PMCx041 ls_mab_alloc.{all_allocations|hardware_prefetcher_allocations|load_store_allocations}
PMCx043 ls_dmnd_fills_from_sys.ext_cache_local
PMCx044 ls_any_fills_from_sys.{mem_io_remote|ext_cache_remote|mem_io_local|ext_cache_local|int_cache|lcl_l2}
PMCx047 ls_misal_loads.{ma4k|ma64}
PMCx059 ls_sw_pf_dc_fills.ext_cache_local
PMCx05a ls_hw_pf_dc_fills.ext_cache_local
PMCx05f ls_alloc_mab_count
PMCx085 bp_l1_tlb_miss_l2_tlb_miss.coalesced_4k
PMCx0ab de_dis_cops_from_decoder.disp_op_type.{any_integer_dispatch|any_fp_dispatch}
PMCx0cc ex_ret_ind_brch_instr
PMCx18e ic_tag_hit_miss.{all_instruction_cache_accesses|instruction_cache_miss|instruction_cache_hit}
PMCx1c7 ex_ret_msprd_brnch_instr_dir_msmtch
PMCx28f op_cache_hit_miss.{all_op_cache_accesses|op_cache_miss|op_cache_hit}
Section 2.1.17.2 "Performance Measurement" of "PPR for AMD Family 19h,
Model 01h, Revision B1 Processors - 55898 Rev 0.35 - Feb 5, 2021." lists
new metrics. Add them.
Preserve the events for Zen3 if they are measurable and non-zero as taken
from Zen2 directory even if the PPR of Zen3 [1] omits them. Those events
are the following:
PMCx000 fpu_pipe_assignment.{total|total0|total1|total2|total3}
PMCx004 fp_num_mov_elim_scal_op.{optimized|opt_potential|sse_mov_ops_elim|sse_mov_ops}
PMCx02D ls_rdtsc
PMCx040 ls_dc_accesses
PMCx046 ls_tablewalker.{iside|ic_type1|ic_type0|dside|dc_type1|dc_type0}
PMCx061 l2_request_g2.{group1|ls_rd_sized|ls_rd_sized_nc|ic_rd_sized|ic_rd_sized_nc|smc_inval|bus_lock_originator|bus_locks_responses}
PMCx062 l2_latency.l2_cycles_waiting_on_fills
PMCx063 l2_wcb_req.{wcb_write|wcb_close|zero_byte_store|cl_zero}
PMCx06d l2_fill_pending.l2_fill_busy
PMCx080 ic_fw32
PMCx081 ic_fw32_miss
PMCx086 bp_snp_re_sync
PMCx087 ic_fetch_stall.{ic_stall_any|ic_stall_dq_empty|ic_stall_back_pressure}
PMCx08a bp_l1_btb_correct
PMCx08c ic_cache_inval.{l2_invalidating_probe|fill_invalidated}
PMCx099 bp_tlb_rel
PMCx0a9 de_dis_uop_queue_empty_di0
PMCx0c7 ex_ret_brn_resync
PMCx28a ic_oc_mode_switch.{oc_ic_mode_switch|ic_oc_mode_switch}
L3PMCx01 l3_request_g1.caching_l3_cache_accesses
L3PMCx06 l3_comb_clstr_state.{other_l3_miss_typs|request_miss}
