commit c2e4b24ff848bb180f9b9cd873a38327cd219ad2 upstream.
When a trace recorded on a 32-bit device is processed with a 64-bit
binary, the higher 32-bits of the address need to ignored.The lack of this results in the output of the 64-bit pointer
value to the trace as the 32-bit address lookup fails in find_printk().Before:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: 2cec5c058d98c
After:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: RT throttling activated
The problem occurs in PRINT_FIELD when the field is recognized as a
pointer to a string (of the type const char *)Heterogeneous architectures cases below can arise and should be handled:
* Traces recorded using 32-bit addresses processed on a 64-bit machine
* Traces recorded using 64-bit addresses processed on a 32-bit machineReported-by: Juri Lelli

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 \(online\|avail\)'

# perf record usleep 1
# perf report --header-only | grep 'nrcpus \(online\|avail\)'
# nrcpus online : 4
# nrcpus avail : 2After the fix, bringing back the CPUs online:
# perf report --header-only | grep 'nrcpus \(online\|avail\)'

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:

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.

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.Cc: Namhyung Kim

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.Signed-off-by: Adrian Hunter

commit 0bc2f2f7d080561cc484d2d0a162a9396bed3383 upstream.
When setting yup the symbols library we setup several filter lists,
for dsos, comms, symbols, etc, and there is code that, if there are
filters, do certain operations, like recalculate the number of non
filtered histogram entries in the top/report TUI.But they were considering just the "Zoom" filters, when they need to
take into account as well the above mentioned filters (perf top --comms,
--dsos, etc).So store in symbol_conf.has_filter true if any of those filters is in
place.Cc: Adrian Hunter

commit 2c86c7ca7606
Author: Namhyung Kim
Date: Mon Mar 17 18:18:54 2014 -0300perf report: Merge al->filtered with hist_entry->filtered
We stopped dropping samples for things filtered via the --comms, --dsos,
--symbols, etc, i.e. things marked as filtered in the symbol resolution
routines (thread__find_addr_map(), perf_event__preprocess_sample(),
etc).But then, in:
commit 268397cb2a47
Author: Namhyung Kim
Date: Tue Apr 22 14:49:31 2014 +0900perf top/tui: Update nr_entries properly after a filter is applied
We don't take into account entries that were filtered in
perf_event__preprocess_sample() and friends, which leads to
inconsistency in the browser seek routines, that expects the number of
hist_entry->filtered entries to match what it thinks is the number of
unfiltered, browsable entries.So, for instance, when we do:
perf top --symbols ___non_existent_symbol___
the hist_browser__nr_entries() routine thinks there are no filters in
place, uses the hists->nr_entries but all entries are filtered, leading
to a segfault.Tested with:
perf top --symbols malloc,free --percentage=relative
Freezing, by pressing 'f', at any time and doing the math on the
percentages ends up with 100%, ditto for:perf top --dsos libpthread-2.20.so,libxul.so --percentage=relative
Both were segfaulting, all fixed now.
More work needed to do away with checking if filters are in place, we
should just use the nr_non_filtered_samples counter, no need to
conditionally use it or hists.nr_filter, as what the browser does is
just show unfiltered stuff. An audit of how it is being accounted is
needed, this is the minimal fix.Reported-by: Michael Petlan

The commit 512ae1bd6acb ("perf tools: Consolidate management of default
sort orders") changed default value of the 'sort_order' variable to NULL
indicating that users don't set any sort keys on the command line.However it missed to update a check in perf_evlist__tty_browse_hists()
so that 'perf report -T' cannot show the per-thread values after the
normal output. This patch fixes it to work again.Note that the -T option only works on --stdio and neither --sort nor
--parent option was given.Signed-off-by: Namhyung Kim

My patch to add install support for the powerpc selftests had a typo,
leading to the three tests in the pmu directory itself not being
installed.Fixes: 6faeeea44b84 ("selftests: Add install support for the powerpc tests")
