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

Pull perf updates from Ingo Molnar: "Main kernel side changes: - Big reorganization of the x86 perf support code. The old code grew organically deep inside arch/x86/kernel/cpu/perf* and its naming became somewhat messy. The new location is under arch/x86/events/, using the following cleaner hierarchy of source code files: perf/x86: Move perf_event.c .................. => x86/events/core.c perf/x86: Move perf_event_amd.c .............. => x86/events/amd/core.c perf/x86: Move perf_event_amd_ibs.c .......... => x86/events/amd/ibs.c perf/x86: Move perf_event_amd_iommu.[ch] ..... => x86/events/amd/iommu.[ch] perf/x86: Move perf_event_amd_uncore.c ....... => x86/events/amd/uncore.c perf/x86: Move perf_event_intel_bts.c ........ => x86/events/intel/bts.c perf/x86: Move perf_event_intel.c ............ => x86/events/intel/core.c perf/x86: Move perf_event_intel_cqm.c ........ => x86/events/intel/cqm.c perf/x86: Move perf_event_intel_cstate.c ..... => x86/events/intel/cstate.c perf/x86: Move perf_event_intel_ds.c ......... => x86/events/intel/ds.c perf/x86: Move perf_event_intel_lbr.c ........ => x86/events/intel/lbr.c perf/x86: Move perf_event_intel_pt.[ch] ...... => x86/events/intel/pt.[ch] perf/x86: Move perf_event_intel_rapl.c ....... => x86/events/intel/rapl.c perf/x86: Move perf_event_intel_uncore.[ch] .. => x86/events/intel/uncore.[ch] perf/x86: Move perf_event_intel_uncore_nhmex.c => x86/events/intel/uncore_nmhex.c perf/x86: Move perf_event_intel_uncore_snb.c => x86/events/intel/uncore_snb.c perf/x86: Move perf_event_intel_uncore_snbep.c => x86/events/intel/uncore_snbep.c perf/x86: Move perf_event_knc.c .............. => x86/events/intel/knc.c perf/x86: Move perf_event_p4.c ............... => x86/events/intel/p4.c perf/x86: Move perf_event_p6.c ............... => x86/events/intel/p6.c perf/x86: Move perf_event_msr.c .............. => x86/events/msr.c (Borislav Petkov) - Update various x86 PMU constraint and hw support details (Stephane Eranian) - Optimize kprobes for BPF execution (Martin KaFai Lau) - Rewrite, refactor and fix the Intel uncore PMU driver code (Thomas Gleixner) - Rewrite, refactor and fix the Intel RAPL PMU code (Thomas Gleixner) - Various fixes and smaller cleanups. There are lots of perf tooling updates as well. A few highlights: perf report/top: - Hierarchy histogram mode for 'perf top' and 'perf report', showing multiple levels, one per --sort entry: (Namhyung Kim) On a mostly idle system: # perf top --hierarchy -s comm,dso Then expand some levels and use 'P' to take a snapshot: # cat perf.hist.0 - 92.32% perf 58.20% perf 22.29% libc-2.22.so 5.97% [kernel] 4.18% libelf-0.165.so 1.69% [unknown] - 4.71% qemu-system-x86 3.10% [kernel] 1.60% qemu-system-x86_64 (deleted) + 2.97% swapper # - Add 'L' hotkey to dynamicly set the percent threshold for histogram entries and callchains, i.e. dynamicly do what the --percent-limit command line option to 'top' and 'report' does. (Namhyung Kim) perf mem: - Allow specifying events via -e in 'perf mem record', also listing what events can be specified via 'perf mem record -e list' (Jiri Olsa) perf record: - Add 'perf record' --all-user/--all-kernel options, so that one can tell that all the events in the command line should be restricted to the user or kernel levels (Jiri Olsa), i.e.: perf record -e cycles:u,instructions:u is equivalent to: perf record --all-user -e cycles,instructions - Make 'perf record' collect CPU cache info in the perf.data file header: $ perf record usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ] $ perf report --header-only -I | tail -10 | head -8 # CPU cache info: # L1 Data 32K [0-1] # L1 Instruction 32K [0-1] # L1 Data 32K [2-3] # L1 Instruction 32K [2-3] # L2 Unified 256K [0-1] # L2 Unified 256K [2-3] # L3 Unified 4096K [0-3] Will be used in 'perf c2c' and eventually in 'perf diff' to allow, for instance running the same workload in multiple machines and then when using 'diff' show the hardware difference. (Jiri Olsa) - Improved support for Java, using the JVMTI agent library to do jitdumps that then will be inserted in synthesized PERF_RECORD_MMAP2 events via 'perf inject' pointed to synthesized ELF files stored in ~/.debug and keyed with build-ids, to allow symbol resolution and even annotation with source line info, see the changeset comments to see how to use it (Stephane Eranian) perf script/trace: - Decode data_src values (e.g. perf.data files generated by 'perf mem record') in 'perf script': (Jiri Olsa) # perf script perf 693 [1] 4.088652: 1 cpu/mem-loads,ldlat=30/P: ffff88007d0b0f40 68100142 L1 hit|SNP None|TLB L1 or L2 hit|LCK No <SNIP> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - Improve support to 'data_src', 'weight' and 'addr' fields in 'perf script' (Jiri Olsa) - Handle empty print fmts in 'perf script -s' i.e. when running python or perl scripts (Taeung Song) perf stat: - 'perf stat' now shows shadow metrics (insn per cycle, etc) in interval mode too. E.g: # perf stat -I 1000 -e instructions,cycles sleep 1 # time counts unit events 1.000215928 519,620 instructions # 0.69 insn per cycle 1.000215928 752,003 cycles <SNIP> - Port 'perf kvm stat' to PowerPC (Hemant Kumar) - Implement CSV metrics output in 'perf stat' (Andi Kleen) perf BPF support: - Support converting data from bpf events in 'perf data' (Wang Nan) - Print bpf-output events in 'perf script': (Wang Nan). # perf record -e bpf-output/no-inherit,name=evt/ -e ./test_bpf_output_3.c/map:channel.event=evt/ usleep 1000 # perf script usleep 4882 21384.532523: evt: ffffffff810e97d1 sys_nanosleep ([kernel.kallsyms]) BPF output: 0000: 52 61 69 73 65 20 61 20 Raise a 0008: 42 50 46 20 65 76 65 6e BPF even 0010: 74 21 00 00 t!.. BPF string: "Raise a BPF event!" # - Add API to set values of map entries in a BPF object, be it individual map slots or ranges (Wang Nan) - Introduce support for the 'bpf-output' event (Wang Nan) - Add glue to read perf events in a BPF program (Wang Nan) - Improve support for bpf-output events in 'perf trace' (Wang Nan) ... and tons of other changes as well - see the shortlog and git log for details!" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (342 commits) perf stat: Add --metric-only support for -A perf stat: Implement --metric-only mode perf stat: Document CSV format in manpage perf hists browser: Check sort keys before hot key actions perf hists browser: Allow thread filtering for comm sort key perf tools: Add sort__has_comm variable perf tools: Recalc total periods using top-level entries in hierarchy perf tools: Remove nr_sort_keys field perf hists browser: Cleanup hist_browser__fprintf_hierarchy_entry() perf tools: Remove hist_entry->fmt field perf tools: Fix command line filters in hierarchy mode perf tools: Add more sort entry check functions perf tools: Fix hist_entry__filter() for hierarchy perf jitdump: Build only on supported archs tools lib traceevent: Add '~' operation within arg_num_eval() perf tools: Omit unnecessary cast in perf_pmu__parse_scale perf tools: Pass perf_hpp_list all the way through setup_sort_list perf tools: Fix perf script python database export crash perf jitdump: DWARF is also needed perf bench mem: Prepare the x86-64 build for upstream memcpy_mcsafe() changes ...

+Variables
+~~~~~~~~~
+
+colors.*::
+	The variables for customizing the colors used in the output for the
+	'report', 'top' and 'annotate' in the TUI. They should specify the
+	foreground and background colors, separated by a comma, for example:
+
+		medium = green, lightgray
+
+	If you want to use the color configured for you terminal, just leave it
+	as 'default', for example:
+
+		medium = default, lightgray
+
+	Available colors:
+	red, yellow, green, cyan, gray, black, blue,
+	white, default, magenta, lightgray
+
+	colors.top::
+		'top' means a overhead percentage which is more than 5%.
+		And values of this variable specify percentage colors.
+		Basic key values are foreground-color 'red' and
+		background-color 'default'.
+	colors.medium::
+		'medium' means a overhead percentage which has more than 0.5%.
+		Default values are 'green' and 'default'.
+	colors.normal::
+		'normal' means the rest of overhead percentages
+		except 'top', 'medium', 'selected'.
+		Default values are 'lightgray' and 'default'.
+	colors.selected::
+		This selects the colors for the current entry in a list of entries
+		from sub-commands (top, report, annotate).
+		Default values are 'black' and 'lightgray'.
+	colors.jump_arrows::
+		Colors for jump arrows on assembly code listings
+		such as 'jns', 'jmp', 'jane', etc.
+		Default values are 'blue', 'default'.
+	colors.addr::
+		This selects colors for addresses from 'annotate'.
+		Default values are 'magenta', 'default'.
+	colors.root::
+		Colors for headers in the output of a sub-commands (top, report).
+		Default values are 'white', 'blue'.
+
+tui.*, gtk.*::
+	Subcommands that can be configured here are 'top', 'report' and 'annotate'.
+	These values are booleans, for example:
+
+	[tui]
+		top = true
+
+	will make the TUI be the default for the 'top' subcommand. Those will be
+	available if the required libs were detected at tool build time.
+
+buildid.*::
+	buildid.dir::
+		Each executable and shared library in modern distributions comes with a
+		content based identifier that, if available, will be inserted in a
+		'perf.data' file header to, at analysis time find what is needed to do
+		symbol resolution, code annotation, etc.
+
+		The recording tools also stores a hard link or copy in a per-user
+		directory, $HOME/.debug/, of binaries, shared libraries, /proc/kallsyms
+		and /proc/kcore files to be used at analysis time.
+
+		The buildid.dir variable can be used to either change this directory
+		cache location, or to disable it altogether. If you want to disable it,
+		set buildid.dir to /dev/null. The default is $HOME/.debug
+
+annotate.*::
+	These options work only for TUI.
+	These are in control of addresses, jump function, source code
+	in lines of assembly code from a specific program.
+
+	annotate.hide_src_code::
+		If a program which is analyzed has source code,
+		this option lets 'annotate' print a list of assembly code with the source code.
+		For example, let's see a part of a program. There're four lines.
+		If this option is 'true', they can be printed
+		without source code from a program as below.
+
+		│        push   %rbp
+		│        mov    %rsp,%rbp
+		│        sub    $0x10,%rsp
+		│        mov    (%rdi),%rdx
+
+		But if this option is 'false', source code of the part
+		can be also printed as below. Default is 'false'.

+
+        annotate.use_offset::
+		Basing on a first address of a loaded function, offset can be used.
+		Instead of using original addresses of assembly code,
+		addresses subtracted from a base address can be printed.
+		Let's illustrate an example.
+		If a base address is 0XFFFFFFFF81624d50 as below,
+
+		ffffffff81624d50 <load0>
+
+		an address on assembly code has a specific absolute address as below
+
+		ffffffff816250b8:│  mov    0x8(%r14),%rdi
+
+		but if use_offset is 'true', an address subtracted from a base address is printed.
+		Default is true. This option is only applied to TUI.
+
+		             368:│  mov    0x8(%r14),%rdi
+
+	annotate.jump_arrows::
+		There can be jump instruction among assembly code.
+		Depending on a boolean value of jump_arrows,
+		arrows can be printed or not which represent
+		where do the instruction jump into as below.

+		       Overhead  Symbols
+		       ........  .......
+		        33.33%     foo
+		        33.33%     bar
+		        33.33%     baz
+
+	       This is an original overhead and we'll filter out the first 'foo'
+	       entry. The value of 'relative' would increase the overhead of 'bar'
+	       and 'baz' to 50.00% for each, while 'absolute' would show their
+	       current overhead (33.33%).
+
+ui.*::
+	ui.show-headers::
+		This option controls display of column headers (like 'Overhead' and 'Symbol')
+		in 'report' and 'top'. If this option is false, they are hidden.
+		This option is only applied to TUI.
+
+call-graph.*::
+	When sub-commands 'top' and 'report' work with -g/—-children
+	there're options in control of call-graph.
+
+	call-graph.record-mode::
+		The record-mode can be 'fp' (frame pointer), 'dwarf' and 'lbr'.
+		The value of 'dwarf' is effective only if perf detect needed library
+		(libunwind or a recent version of libdw).
+		'lbr' only work for cpus that support it.
+
+	call-graph.dump-size::
+		The size of stack to dump in order to do post-unwinding. Default is 8192 (byte).
+		When using dwarf into record-mode, the default size will be used if omitted.
+
+	call-graph.print-type::
+		The print-types can be graph (graph absolute), fractal (graph relative),
+		flat and folded. This option controls a way to show overhead for each callchain
+		entry. Suppose a following example.
+
+                Overhead  Symbols
+                ........  .......
+                  40.00%  foo
+                          |
+                          ---foo
+                             |
+                             |--50.00%--bar
+                             |          main
+                             |
+                              --50.00%--baz
+                                        main
+
+		This output is a 'fractal' format. The 'foo' came from 'bar' and 'baz' exactly
+		half and half so 'fractal' shows 50.00% for each
+		(meaning that it assumes 100% total overhead of 'foo').
+
+		The 'graph' uses absolute overhead value of 'foo' as total so each of
+		'bar' and 'baz' callchain will have 20.00% of overhead.
+		If 'flat' is used, single column and linear exposure of call chains.
+		'folded' mean call chains are displayed in a line, separated by semicolons.
+
+	call-graph.order::
+		This option controls print order of callchains. The default is
+		'callee' which means callee is printed at top and then followed by its
+		caller and so on. The 'caller' prints it in reverse order.
+
+		If this option is not set and report.children or top.children is
+		set to true (or the equivalent command line option is given),
+		the default value of this option is changed to 'caller' for the
+		execution of 'perf report' or 'perf top'. Other commands will
+		still default to 'callee'.
+
+	call-graph.sort-key::
+		The callchains are merged if they contain same information.
+		The sort-key option determines a way to compare the callchains.
+		A value of 'sort-key' can be 'function' or 'address'.
+		The default is 'function'.
+
+	call-graph.threshold::
+		When there're many callchains it'd print tons of lines. So perf omits
+		small callchains under a certain overhead (threshold) and this option
+		control the threshold. Default is 0.5 (%). The overhead is calculated
+		by value depends on call-graph.print-type.
+
+	call-graph.print-limit::
+		This is a maximum number of lines of callchain printed for a single
+		histogram entry. Default is 0 which means no limitation.
+
+report.*::
+	report.percent-limit::
+		This one is mostly the same as call-graph.threshold but works for
+		histogram entries. Entries having an overhead lower than this
+		percentage will not be printed. Default is '0'. If percent-limit
+		is '10', only entries which have more than 10% of overhead will be
+		printed.
+
+	report.queue-size::
+		This option sets up the maximum allocation size of the internal
+		event queue for ordering events. Default is 0, meaning no limit.
+
+	report.children::
+		'Children' means functions called from another function.
+		If this option is true, 'perf report' cumulates callchains of children
+		and show (accumulated) total overhead as well as 'Self' overhead.
+		Please refer to the 'perf report' manual. The default is 'true'.
+
+	report.group::
+		This option is to show event group information together.
+		Example output with this turned on, notice that there is one column
+		per event in the group, ref-cycles and cycles:
+
+		# group: {ref-cycles,cycles}
+		# ========
+		#
+		# Samples: 7K of event 'anon group { ref-cycles, cycles }'
+		# Event count (approx.): 6876107743
+		#
+		#         Overhead  Command      Shared Object               Symbol
+		# ................  .......  .................  ...................
+		#
+		    99.84%  99.76%  noploop  noploop            [.] main
+		     0.07%   0.00%  noploop  ld-2.15.so         [.] strcmp
+		     0.03%   0.00%  noploop  [kernel.kallsyms]  [k] timerqueue_del
+
+top.*::
+	top.children::
+		Same as 'report.children'. So if it is enabled, the output of 'top'
+		command will have 'Children' overhead column as well as 'Self' overhead
+		column by default.
+		The default is 'true'.
+
+man.*::
+	man.viewer::
+		This option can assign a tool to view manual pages when 'help'
+		subcommand was invoked. Supported tools are 'man', 'woman'
+		(with emacs client) and 'konqueror'. Default is 'man'.
+
+		New man viewer tool can be also added using 'man.<tool>.cmd'
+		or use different path using 'man.<tool>.path' config option.
+
+pager.*::
+	pager.<subcommand>::
+		When the subcommand is run on stdio, determine whether it uses
+		pager or not based on this value. Default is 'unspecified'.
+
+kmem.*::
+	kmem.default::
+		This option decides which allocator is to be analyzed if neither
+		'--slab' nor '--page' option is used. Default is 'slab'.
+
+record.*::
+	record.build-id::
+		This option can be 'cache', 'no-cache' or 'skip'.
+		'cache' is to post-process data and save/update the binaries into
+		the build-id cache (in ~/.debug). This is the default.
+		But if this option is 'no-cache', it will not update the build-id cache.
+		'skip' skips post-processing and does not update the cache.
