Merge tag 'perf-tools-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:
"Fixes:
- Fixes for 'perf bench numa'.

- Always memset source before memcpy in 'perf bench mem'.

- Quote CC and CXX for their arguments to fix build in environments
using those variables to pass more than just the compiler names.

- Fix module symbol processing, addressing regression detected via
"perf test".

- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
test' entry.

Improvements:
- Add script to autogenerate socket family name id->string table from
copy of kernel header, used so far in 'perf trace'.

- 'perf ftrace' improvements to provide similar options for this
utility so that one can go from 'perf record', 'perf trace', etc to
'perf ftrace' just by changing the name of the subcommand.

- Prefer new "sched:sched_waking" trace event when it exists in 'perf
sched' post processing.

- Update POWER9 metrics to utilize other metrics.

- Fall back to querying debuginfod if debuginfo not found locally.

Miscellaneous:
- Sync various kvm headers with kernel sources"

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Ftrace is one of the last W^X violators (after this only KLP is
left). These patches move it over to the generic text_poke()
interface and thereby get rid of this oddity. This requires a
surprising amount of surgery, by Peter Zijlstra.

- x86/AMD PMUs: add support for 'Large Increment per Cycle Events' to
count certain types of events that have a special, quirky hw ABI
(by Kim Phillips)

- kprobes fixes by Masami Hiramatsu

Lots of tooling updates as well, the following subcommands were
updated: annotate/report/top, c2c, clang, record, report/top TUI,
sched timehist, tests; plus updates were done to the gtk ui, libperf,
headers and the parser"

Merge tag 'perf-core-for-mingo-5.6-20200106' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

perf record:

Alexey Budankov:

- Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
mask size limitation of cpu_set_t type.

perf report/top TUI:

Arnaldo Carvalho de Melo:

- Make ENTER consistently present the pop up menu with and without call
chains, to eliminate confusion. The menu continues available at all times
use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
the call chains for a top level histogram entry and 'E' to expand all call
chains in all top level entries. Extra info about these options was added to
the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
to the main vmlinux entries, to avoid having to press enter and then select
"Zoom into the kernel DSO".

perf sched timehist:

David Ahern:

- Add support for filtering on CPU.

perf tests:

Arnaldo Carvalho de Melo:

- Show expected versus obtained values in bp_signal test.

libperf:

Jiri Olsa:

- Move to tools/lib/perf.

- Add man pages.

libapi:

Andrey Zhizhikin:

- Fix gcc9 stringop-truncation compilation error.

tools lib:

Vitaly Chikunov:

- Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

libperf: Add man pages

Change the man page generation to asciidoc, because it's easier to use
and has been more commonly used in related projects. Remove the current
rst pages.

Add 3 man pages to have a base for more additions:

libperf.3 - overall description
libperf-counting.7 - counting basics explained on simple example
libperf-sampling.7 - sampling basics explained on simple example

The plan is to add more man pages to cover the basic API.

The build generates html and man pages:

$ cd tools/lib/perf/Documentation
$ make
ASCIIDOC libperf.xml
XMLTO libperf.3
ASCIIDOC libperf-counting.xml
XMLTO libperf-counting.7
ASCIIDOC libperf-sampling.xml
XMLTO libperf-sampling.7
ASCIIDOC libperf.html
ASCIIDOC libperf-counting.html
ASCIIDOC libperf-sampling.html

Add the following install targets:

install-man - man pages
install-html - html version of man pages
install-examples - examples mentioned in the man pages
