tools lib traceevent: Fix output of %llu for 64 bit values read on 32 bit machines

2016-02-25T19:58:52+00:00

commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream.

When a long value is read on 32 bit machines for 64 bit output, the
parsing needs to change "%lu" into "%llu", as the value is read
natively.

Unfortunately, if "%llu" is already there, the code will add another "l"
to it and fail to parse it properly.

perf trace: Fix documentation for -i

2016-02-25T19:58:52+00:00

commit 956959f6b7a982b2e789a7a8fa1de437074a5eb9 upstream.

The -i flag was incorrectly listed as a short flag for --no-inherit.  It
should have only been listed as a short flag for --input.

This documentation error has existed since the --input flag was
introduced in 6810fc915f7a89d8134edb3996dbbf8eac386c26 (perf trace: Add
option to analyze events in a file versus live).

tools/net: Use include/uapi with __EXPORTED_HEADERS__

2016-01-23T04:34:46+00:00

[ Upstream commit d7475de58575c904818efa369c82e88c6648ce2e ]

Use the local uapi headers to keep in sync with "recently" added #define's
(e.g. SKF_AD_VLAN_TPID).  Refactored CFLAGS, and bpf_asm doesn't need -I.

perf header: Fixup reading of HEADER_NRCPUS feature

2015-10-22T21:39:17+00:00

commit caa470475d9b59eeff093ae650800d34612c4379 upstream.

The original patch introducing this header wrote the number of CPUs available
and online in one order and then swapped those values when reading, fix it.

Before:

  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 4
  # echo 0 > /sys/devices/system/cpu/cpu2/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 3
  # echo 0 > /sys/devices/system/cpu/cpu1/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 2

After the fix, bringing back the CPUs online:

  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 2
  # nrcpus avail : 4
  # echo 1 > /sys/devices/system/cpu/cpu2/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 3
  # nrcpus avail : 4
  # echo 1 > /sys/devices/system/cpu/cpu1/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 4

perf stat: Get correct cpu id for print_aggr

2015-10-22T21:39:17+00:00

commit 601083cffb7cabdcc55b8195d732f0f7028570fa upstream.

print_aggr() fails to print per-core/per-socket statistics after commit
582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
used to get aggregated id.

Here is an example:

Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
cpumask 0,18)

  $ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core sleep 2

Without this patch, it failes to get CPU 18 result.

   Performance counter stats for 'CPU(s) 0,18':

  S0-C0           1            7526851      cycles
  S0-C0           1               1.05 MiB  uncore_imc_0/cas_count_read/
  S1-C0           0            cycles
  S1-C0           0       MiB  uncore_imc_0/cas_count_read/

With this patch, it can get both CPU0 and CPU18 result.

   Performance counter stats for 'CPU(s) 0,18':

  S0-C0           1            6327768      cycles
  S0-C0           1               0.47 MiB  uncore_imc_0/cas_count_read/
  S1-C0           1             330228      cycles
  S1-C0           1               0.29 MiB  uncore_imc_0/cas_count_read/

perf hists: Update the column width for the "srcline" sort key

2015-10-22T21:39:17+00:00

commit e8e6d37e73e6b950c891c780745460b87f4755b6 upstream.

When we introduce a new sort key, we need to update the
hists__calc_col_len() function accordingly, otherwise the width
will be limited to strlen(header).

We can't update it when obtaining a line value for a column (for
instance, in sort__srcline_cmp()), because we reset it all when doing a
resort (see hists__output_recalc_col_len()), so we need to, from what is
in the hist_entry fields, set each of the column widths.

perf tools: Fix copying of /proc/kcore

2015-10-22T21:39:17+00:00

commit b5cabbcbd157a4bf5a92dfc85134999a3b55342d upstream.

A copy of /proc/kcore containing the kernel text can be made to the
buildid cache. e.g.

	perf buildid-cache -v -k /proc/kcore

To workaround objdump limitations, a copy is also made when annotating
against /proc/kcore.

The copying process stops working from libelf about v1.62 onwards (the
problem was found with v1.63).

The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
because additional validation has been added to gelf_getphdr().

The use of gelf_getphdr() is a misguided attempt to get default
initialization of the Gelf_Phdr structure.  That should not be
necessary because every member of the Gelf_Phdr structure is
subsequently assigned.  So just remove the call to gelf_getphdr().

Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
removed also.

Committer notes:

Note to stable@kernel.org, from Adrian in the cover letter for this
patchkit:

The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
it is important enough for stable.

tools/power turbostat: Use $(CURDIR) instead of $(PWD) and add support for O= option in Makefile

2015-05-06T19:59:16+00:00

commit f82263c6989c31ae9b94cecddffb29dcbec38710 upstream.

Since commit ee0778a30153
("tools/power: turbostat: make Makefile a bit more capable")
turbostat's Makefile is using

  [...]
  BUILD_OUTPUT    := $(PWD)
  [...]

which obviously causes trouble when building "turbostat" with

  make -C /usr/src/linux/tools/power/x86/turbostat ARCH=x86 turbostat

because GNU make does not update nor guarantee that $PWD is set.

This patch changes the Makefile to use $CURDIR instead, which GNU make
guarantees to set and update (i.e. when using "make -C ...") and also
adds support for the O= option (see "make help" in your root of your
kernel source tree for more details).
