perf cpumap: Remove needless includes from cpumap.h · 5e51b0bb

由 Arnaldo Carvalho de Melo 提交于 8月 22, 2019

The util/cpumap.h file doesn't use anything in refcount.h not in
debug.h, it needs just a forward reference to 'struct cpu_map_data',
that is defined in util/event.h and cpumap.h was getting indirectly via,
of all things, debug.h

perf evsel: Switch to libperf's cpumap.h · f7004f59

由 Arnaldo Carvalho de Melo 提交于 8月 21, 2019

We don't need what is in perf's util/cpumap.h, just the struct cpu_map
that is in libperf's internal/cpumap.h file to cover this one case:

tools/perf/util/evsel.h:215:27: error: dereferencing pointer to incomplete type ‘struct perf_cpu_map’
215 | return evsel__cpus(evsel)->nr;

So switch to libperf's cpumap.h and add some missing struct foward
declarations and include sys/types.h to get pid_t.

perf evsel: Add missing perf/evsel.h header in util/evsel.h · 69714a4e

由 Arnaldo Carvalho de Melo 提交于 8月 21, 2019

Since util/evsel.h uses perf_evsel__cpus() that has its prototype in
libperf's perf/evsel.h file, we need it explicitely included.

This was working by luck as util/evsel.h includes counts.h, but that is
not necessary, just some forward declarations, so, before we remove
counts.h from util/evsel.h, add what is realli needed.

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

callchains:

   Alexey Budankov:

  - Allow collecting LBR together with DWARF callchains, for workloads
    where the userspace stack size collected is not big enough for
    pure DWARF based unwinding.

  - Dump the LBR call stack in 'perf report -D'.

perf top:

  Arnaldo Carvalho de Melo:

  - Show visual cue at start to state that the minimal set of samples
    are being collected prior to sorting/bucketizing/displaying.

CoreSight (ARM hardware tracing):

  Leo Yan:

  - Support sample flags 'insn' and 'insnlen'.

core:

  Adrian Hunter:

  - Add comment for 'idx' member in 'struct perf_sample_id.

tools headers:

  Arnaldo Carvalho de Melo:

  - Synchronize linux/bits.h, which required grabbing a copy of the kernel
    const.h headers and some changes in the ordering of header directories.

  - Sync x86's asm/cpufeatures.h with the with the kernel, no change in
    any of the tools.

libperf:

  Jiri Olsa:

  - Fix arch include paths.

libtraceevent:

  Steven Rostedt (VMware):

Sometimes we want just to print a message on the center of the screen,

Also expose __ui__info_window() as an optimization for cases where such
message is to be printed while holding the ui lock.

perf ui: Make 'exit_msg' optional in ui__question_window() · 9e79ff77

由 Arnaldo Carvalho de Melo 提交于 8月 19, 2019

We will not need it when refactoring this function to be
non-interactive, so make it optional.

perf cs-etm: Support sample flags 'insn' and 'insnlen' · a4973d8f

由 Leo Yan 提交于 8月 15, 2019

The synthetic branch and instruction samples are missed to set
instruction related info, thus the perf tool fails to display samples
with flags '-F,+insn,+insnlen'.

The CoreSight trace decoder provides sufficient information to decide
the instruction size based on the ISA type: A64/A32 instructions are
32-bit size, but one exception is the T32 instruction size, which might
be 32-bit or 16-bit.

This patch handles these cases and it reads the instruction values from
DSO file; thus can support the flags '-F,+insn,+insnlen'.

perf report: Prefer DWARF callstacks to LBR ones when captured both · 10ccbc1c

由 Alexey Budankov 提交于 8月 09, 2019

Display DWARF based callchains when the perf.data file contains raw thread
stack data as LBR callstack data.

This changes the output from the branch stack based one, i.e. without
this patch, for the same file as in the previous csets:

perf record: Enable LBR callstack capture jointly with thread stack · 25663496

由 Alexey Budankov 提交于 8月 09, 2019

Enable '-j stack' applicability together with '--call-graph dwarf'
option so thread stack data and LBR call stack could be captured
jointly:

  $ perf record -g --call-graph dwarf,1024 -j stack,u -- stack_test

Collected LBR call stack can be used to augment DWARF call stack
calculated from the raw thread stack data and to provide more
comprehensive call stack information for cases when collected SIZE is
not enough to cover complete thread stack.

Such cases are typical for workloads that allocate large arrays of data
on its threads stacks or the possible SIZE to collect can't be large
enough due to workload nature or system configuration and this is where
hardware captured LBR call stacks can provide missing stack frames.
Possible DWARF plus LBR call stacks consolidation algorithm description
follows.

With this patch set perf report command UI currently ignores collected
LBR call stack data and still provides DWARF based call stacks
information.

tools lib traceevent: Fix "robust" test of do_generate_dynamic_list_file · 82a2f884

由 Steven Rostedt (VMware) 提交于 8月 05, 2019

The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.

Add 'tr "w" "W"' to merge the two and not worry about the ordering.

The next cset will grap const.h copies from the kernel to keep bits.h
in sync as it started to use linux/const.h, that in turn includes
uapi/linux/const.h.

So now we have a file with the same name in tools/include and
tools/uapi/include, and one includes the other, we need to have
tools/include/uapi/ after tools/include/ for this to work, fix it.
