- Allow vendors to provide JSON files describing PMU events, that then
get parsed to generate C tables that are linked against perf, allowing
the use of the names in their documentations, such as:
# perf list l1d
List of pre-defined events (to be used in -e):
Cache:
l1d.replacement
[L1D data line replacements]
l1d_pend_miss.fb_full
[Cycles a demand request was blocked due to Fill Buffers inavailability]
l1d_pend_miss.pending
[L1D miss oustandings duration in cycles]
l1d_pend_miss.pending_cycles
[Cycles with L1D load Misses outstanding]
l1d_pend_miss.pending_cycles_any
[Cycles with L1D load Misses outstanding from any thread on physical core]
l2_trans.l1d_wb
[L1D writebacks that access L2 cache]
Pipeline:
cycle_activity.cycles_l1d_miss
[Cycles while L1 cache miss demand load is outstanding]
cycle_activity.cycles_l1d_pending
[Cycles while L1 cache miss demand load is outstanding]
cycle_activity.stalls_l1d_miss
[Execution stalls while L1 cache miss demand load is outstanding]
cycle_activity.stalls_l1d_pending
[Execution stalls while L1 cache miss demand load is outstanding]
The above example was done on a Broadwell based ThinkPad t450s after
downloading and installing such JSON files which will be added to the
tools/perf/pmu-events/ directory in a subsequent patchkit.
Now one can use those names with -e/--event in all 'perf tools'.

- Add a missing pointer dereference in 'perf probe' (Colin Ian King)
- Add support for building host programs to be used in generating files
to be used in the build process, such as fixdep and jevents, fixing
the usage of these features in a cross compilation setup (Jiri Olsa)
