Subject: [PATCH 3/3] perf vendor events amd: Update Zen 5 data cache fill events
For events that count data cache fills, some combinations of the unit
mask bits are useful for counting fills from local caches, DRAM or any
far sources. However, named events currently exist for PMCx044 (Any Data
Cache Fills) only. Add similar events for the following base events.
* PMCx043 (Demand Data Cache Fills)
* PMCx059 (Software Prefetch Data Cache Fills)
* PMCx05A (Hardware Prefetch Data Cache Fills)
While at it, remove "ls_any_fills_from_sys.all_dram_io" since it is a
duplicate of "ls_any_fills_from_sys.dram_io_all".
Event descriptions can be found in Section 2.1.16.5.2 "Load/Store (LS)
Events" of the Processor Programming Reference (PPR) for AMD Family 1Ah
Model 02h Revision C1 Processors document available at the link below.
