This patch adds PMU events for AMD Zen2 core based processors, namely,
Matisse (model 71h), Castle Peak (model 31h) and Rome (model 2xh), as
documented in the AMD Processor Programming Reference for Matisse [1].
Zen2 adds some additional counters that are not present in Zen1 and
events for them have been added in this patch. Some counters have also
been removed for Zen2 thatwere previously present in Zen1 and have been
confirmed to always sample zero on zen2. These added/removed counters
have been omitted for brevity.
Note that PPR for Zen2 [1] does not include some counters that were
documented in the PPR for Zen1 based processors [2]. After having tested
these counters, some of them that still work for zen2 systems have been
preserved in the events for zen2. The counters that are omitted in [1]
but are still measurable and non-zero on zen2 (tested on a Ryzen 3900X
system) are the following:
PMC 0x000 fpu_pipe_assignment.{total|total0|total1|total2|total3}
PMC 0x004 fp_num_mov_elim_scal_op.*
PMC 0x046 ls_tablewalker.*
PMC 0x062 l2_latency.l2_cycles_waiting_on_fills
PMC 0x063 l2_wcb_req.*
PMC 0x06D l2_fill_pending.l2_fill_busy
PMC 0x080 ic_fw32
PMC 0x081 ic_fw32_miss
PMC 0x086 bp_snp_re_sync
PMC 0x087 ic_fetch_stall.*
PMC 0x08C ic_cache_inval.*
PMC 0x099 bp_tlb_rel
PMC 0x0C7 ex_ret_brn_resync
PMC 0x28A ic_oc_mode_switch.*
L3PMC 0x001 l3_request_g1.*
L3PMC 0x006 l3_comb_clstr_state.*

I'd like to see the list, if at all possible.

How do you know there aren't others, given your workload just may have not triggered some? This is why ultimately I'd like to use the AMD-sanctioned events from the PPRs.

So at first glance of this patch, I'm seeing at least these last two events present in these PPRs:
54945_3.03_ppr_ZP_B2_pub
55570-B1_3.14_ppr_B1_pub
55803_0.54-PUB
56176_ppr_Family_17h_Model_71h_B0_pub_Rev_3.06
and when testing the events on my zen1 system, sure enough, they return non-zero values.
So do we need to correct the zen1 events first?
Thanks,
Kim
