After the commit ffd3d18c20b8 ("perf tools: Add ARM Statistical Profiling Extensions (SPE) support") is merged, "perf record" and "perf report --dump-raw-trace" have been supported. However, the raw data that is dumped cannot be used without parsing.
This patchset is to improve the "perf report" support for spe, and further process the data. Currently, support for the three events of llc-miss, tlb-miss, and branch-miss is added.
And through the spe to support the precise ip of the branch-misses event, like "branch-misses:pp".
v1->v2: Some cleanup and bugfix fixes were made, and support for the precise ip of branch-misses was added. Thanks for the suggestions of Jeremy and James.
Tan Xiaojun (4): perf tools: Move arm-spe-pkt-decoder.h/c to the new dir perf tools: Add support for "report" for some spe events perf report: Add --spe options for arm-spe perf tools: Support "branch-misses:pp" on arm64
