perf vendor events amd: Add L3 cache events for Family 17h
Allow users to symbolically specify L3 events for Family 17h processors
using the existing AMD Uncore driver.
Source of events descriptions are from section 2.1.15.4.1 "L3 Cache PMC
Events" of the latest Family 17h PPR, available here:
https://www.amd.com/system/files/TechDocs/55570-B1_PUB.zip
Opnly BriefDescriptions added, since they show with and without
the -v and --details flags.
Tested with:
# perf stat -e l3_request_g1.caching_l3_cache_accesses,amd_l3/event=0x01,umask=0x80/,l3_comb_clstr_state.request_miss,amd_l3/event=0x06,umask=0x01/ perf bench mem memcpy -s 4mb -l 100 -f default
