Currently, if we use perf kvm --guestkallsyms --guestmodules report, we
can not get the perf information from perf data file. All sample are
shown as unknown.
Reproducing steps:
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.624 MB perf.data.guest (~27260 samples) ]
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules report |grep %
100.00% [guest/6471] [unknown] [g] 0xffffffff8164f330
This bug was introduced by 207b57926 (perf kvm: Fix regression with guest machine creation).
In original code, it uses perf_session__find_machine(), it means we deliver symbol to machine
which has the same pid, if no machine found, deliver it to *default* guest. But if we use
perf_session__findnew_machine() here, if no machine was found, new machine with pid will be built
and added. Then the default guest which with pid == 0 will never get a symbol.
And because the new machine initialized here has no kernel map created, the symbol delivered to
it will be marked as "unknown".
This patch here is to revert commit 207b57926 and fix the SEGFAULT bug in another way.
Verification steps:
# ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.651 MB perf.data.guest (~28437 samples) ]
# ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules report |grep %

Move those print functions under "if (use_browser == 0)" so that they
don't interfere with TUI output.
Maybe they can handle other UIs later.

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.
Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

1. Since all callers either test if it is less than zero or assign its
result to an int variable, convert it from ssize_t to int;
2. There is just one use for the 'session' variable, so use rec->session
directly instead;
3. No need to store the result of perf_data_file__write, since that
result is either 'size' or -1, the later making the error result to
be stored in 'errno' and accessed thru printf's %m in the pr_err
call.

The pevent_filter_strerror() function is for receiving actual error
message from pevent_errno value. To do that, add a static buffer to
event_filter for saving internal error message
If a failed function saved other information in the static buffer
returns the information, otherwise returns generic error message.

The commit 09600e0f9ebb ("perf tools: Compare dso's also when comparing
symbols") added a comparison of dso when comparing symbol.
But if the sort key already has dso, it doesn't need to do it again
since entries have a different dso already filtered out.

If a hist entry doesn't have symbol information, compare it with its
address. Currently it only compares its level or whether it's NULL.
This can lead to an undesired result like an overhead exceeds 100%
especially when callchain accumulation is enabled by later patch.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and refactorings from Arnaldo Carvalho de Melo:
New features:
. In perf timechart:
- Add backtrace support to CPU info
. Print pid along the name
. Add support for CPU topology
. Add new option --highlight'ing threads, be it by name or,
if a numeric value is provided, that run more than given duration.
From Stanislav Fomichev.
Refactorings:
. Rename some struct DSO binary_type related members and methods,
to clarify its purpose and need for differentiation from symtab_type,
i.e. one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from.
. Convert to new topic libraries, starting with an API one (sysfs, debugfs,
etc), renaming liblk in the process, from Borislav Petkov.
. Get rid of some more panic() like error handling in libtraceevent,
from Namhyung Kim.

Those functions stringify filter arguments.
As caller of those functions handles NULL string properly, it seems that
it's enough to return NULL rather than calling die().

It was called "data_type", but in this context "data" is way too vague,
it could mean the "data" ELF segment, or something else.
Since we have dso__read_binary_type_filename() and the values this field
receives are all DSO__BINARY_TYPE_<FOO> we may as well call it
"binary_type" for consistency sake.
It also seems more appropriate since it determines if we can do
operations like annotation and DWARF unwinding, that needs more than
just the symtab, requiring access to ELF text segments, CFI ELF
sections, etc.

PERF_EVENT_IOC_PERIOD"
This reverts commit 3581fe0ef37ce12ac7a4f74831168352ae848edc.

we no longer have to play this horrible game.

Vince Weaver reports that, on all architectures apart from ARM,
PERF_EVENT_IOC_PERIOD doesn't actually update the period until the next
event fires. This is counter-intuitive behaviour and is better dealt
with in the core code.
This patch ensures that the period is forcefully reset when dealing with
such a request in the core code. A subsequent patch removes the
equivalent hack from the ARM back-end.

Using dso__binary_type_file() make it look like this function will
return a file, not just its filename, so rename it to:
dso__read_binary_type_filename()
to make its purpose clear, just like we have:
dso__read_running_kernel_build_id()

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.
For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.
acme:
"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.
But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."
