Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2019-07-20T18:06:12+00:00

Pull perf tooling updates from Thomas Gleixner:
 "A set of perf improvements and fixes:

  perf db-export:
   - Improvements in how COMM details are exported to databases for post
     processing and use in the sql-viewer.py UI.

   - Export switch events to the database.

  BPF:
   - Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just
     like selftests/bpf/bpf_rlimit.h do, which makes errors due to
     exhaustion of this limit, which are kinda cryptic (EPERM sometimes)
     less frequent.

  perf version:
   - Fix segfault due to missing OPT_END(), noticed on PowerPC.

  perf vendor events:
   - Add JSON files for IBM s/390 machine type 8561.

  perf cs-etm (ARM):
   - Fix two cases of error returns not bing done properly: Invalid
     ERR_PTR() use and loss of propagation error codes"

  Segmentation fault (core dumped)

Fix this.

2019-07-11T15:45:02+00:00

The 'err' variable is set in the error path, but it's not returned to
callers.  Don't always return -EINVAL, return err.

perf cs-etm: Remove errnoeous ERR_PTR() usage in cs_etm__process_auxtrace_info

2019-07-11T15:42:46+00:00

intlist__findnew() doesn't uses ERR_PTR() as a return mechanism
so its callers shouldn't try to extract the error using PTR_ERR(
ret) from intlist__findnew(), make cs_etm__process_auxtrace_info
return -ENOMEM instead.

perf scripts python: export-to-postgresql.py: Export switch events

2019-07-10T16:05:12+00:00

Export switch events to a new table 'context_switches' and create a view
'context_switches_view'. The table and view will show automatically in the
exported-sql-viewer.py script.

If the table ends up empty, then it and the view are dropped.
