perf stat on PPC currently fails to run:
$ perf stat -- sleep 1
Error: open_counter returned with 6 (No such device or address). /bin/dmesg may provide additional information.Fatal: Not all events could be opened.
The problem is that until 2.6.37 (behavior changed with commit b0a873e)
perf on PPC returns ENXIO when hw_perf_event_init() fails. With this
patch we get the expected behavior:$ perf stat -v -- sleep 1
cycles event is not supported by the kernel.

We don't know what types of warnings different versions of flex
and bison combined with different versions of gcc is going to
generate, so just punt and don't warn about anything.This fixes the build of perf for me on an openSUSE 12.1 system.

ktest: Fix reboot on success stopping all reboots
ktest.pl: Fix combined usage of BISECT_REVERSE and BISECT_SKIP -
By default, perf stat sets exclude_guest = 1. But when you run perf on a
kernel which does not support host/guest filtering, then you get an
error saying the event in unsupported. This comes from the fact that
when the perf_event_attr struct passed by the user is larger than the
one known to the kernel there is safety check which ensures that all
unknown bits are zero. But here, exclude_guest is 1 (part of the unknown
bits) and thus the perf_event_open() syscall return EINVAL.To my surprise, running perf record on the same kernel did not exhibit
the problem. The reason is that perf record handles the problem by
catching the error and retrying with guest/host excludes set to zero.
For some reason, this was not done with perf stat. This patch fixes this
problem.Signed-off-by: Stephane Eranian

The change to let individual tests decide to reboot the machine on
success of the entire test also prevented errors from rebooting
when an error was detected.The "no_reboot" variable was only cleared if the test had
reboot_on_success set. But the no_reboot variable also prevents the test
rebooting when an error was detected even when REBOOT_ON_ERROR was set.Add a new "reboot_success" variable that is used to determine if the
test should reboot on success and not touch the no_reboot variable.Signed-off-by: Steven Rostedt
-
When BISECT_REVERSE and BISECT_SKIP are used together with boot or test
testing, build failures are treated as boot or test failures and
'git bisect bad' is executed instead of 'git bisect skip'. This is because
the $ret value of -1 is treated as a build failure, but the $reverse_bisect
logic does not properly handle this.Simple fix, only invert it if it is positive.

When loading symbols from DSO we check multiple paths of DSO binary
until we succeed to load symbols ('.symtab' section). Once symbols are
read we try to load also plt symbols.During the reading of plt symbols, the dso file is reopened from
location given by dso->long_name. This could be wrong in case we want
process buildid binaries.The change is to make the plt symbols being read from the DSO path, that
normal symbols were read from.Signed-off-by: Jiri Olsa

Running 'perf kvm --host --guest --guestmount /tmp/guestmount record -a -g -- sleep 2'
Was resulting in a segfault. For event type PERF_RECORD_MMAP,
event->ip.pid is being used in perf_session__find_machine_for_cpumode,
which is not correct.The event->ip.pid field happens to be 0 in this case and results in
returning a NULL machine object. Finally, access to self->pid in
machine__mmap_name, results in a segfault later.For PERF_RECORD_MMAP type, pass event->mmap.pid.

This routine was checking only if the provided address was after
sym->end, not if it was before sym->start.Fix that by checking for both and return in both cases -ERANGE, so that
tools can communicate this to the user properly, or if they chose so, to
abort.This problem was reported previously but the fixes involved either doing
what was being done for the > end case, i.e. silently drop the sample,
returning 0, or aborting at this function, which is in a lib (or better,
is slated to be at some point) and shouldn't abort.The 'report' tool already checks this value and uses pr_debug to warn
the user.This patch makes the 'top' tool check it too and warn once per map where
such range problem takes place.Reported-by: David Miller

When a process exec()'s, all the maps are retired, but we keep the hist
entries around which hold references to those outdated maps.If the same library gets mapped in for which we have hist entries, a new
map will be created. But when we take a perf entry hit within that map,
we'll find the existing hist entry with the older map.This causes symbol translations to be done incorrectly. For example,
the perf entry processing will lookup the correct uptodate map entry and
use that to calculate the symbol and DSO relative address. But later
when we update the histogram we'll translate the address using the
outdated map file instead leading to conditions such as out-of-range
offsets in symbol__inc_addr_samples().Therefore, update the map of the hist_entry dynamically at lookup/
creation time.Signed-off-by: David S. Miller

Sometimes users have turbostat running in interval mode
when they take processors offline/online.Previously, turbostat would survive, but not gracefully.
Tighten up the error checking so turbostat notices
changesn sooner, and print just 1 line on change:turbostat: re-initialized with num_cpus %d
Signed-off-by: Len Brown

turbostat uses /dev/cpu/*/msr interface to read MSRs.
For modern systems, it reads 10 MSR/CPU. This can
be observed as 10 "Function Call Interrupts"
per CPU per sample added to /proc/interrupts.This overhead is measurable on large idle systems,
and as Yoquan Song pointed out, it can even trick
cpuidle into thinking the system is busy.Here turbostat re-schedules itself in-turn to each
CPU so that its MSR reads will always be local.
This replaces the 10 "Function Call Interrupts"
with a single "Rescheduling interrupt" per sample
per CPU.On an idle 32-CPU system, this shifts some residency from
the shallow c1 state to the deeper c7 state:# ./turbostat.old -s

We were not noticing it because symbol__inc_addr_samples was erroneously
dropping samples that hit the last byte in a function.Working on a fix for a problem reported by David Miller, Stephane
Eranian and Sorin Dumitru, where addresses < sym->start were causing
problems, I noticed this other problem.Cc: David Ahern

hugepage-mmap.c, hugepage-shm.c and map_hugetlb.c in Documentation/vm are
simple pass/fail tests, It's better to promote them to
tools/testing/selftests.Thanks suggestion of Andrew Morton about this. They all need firstly
setting up proper nr_hugepages and hugepage-mmap need to mount hugetlbfs.
So I add a shell script run_vmtests to do such work which will call the
three test programs and check the return value of them.Changes to original code including below:
a. add run_vmtests script
b. return error when read_bytes mismatch with writed bytes.
c. coding style fixes: do not use assignment in if condition[akpm@linux-foundation.org: build the targets before trying to execute them]
[akpm@linux-foundation.org: Documentation/vm/ no longer has a Makefile. Fixes "make clean"]

tools/ is the better place for vm tools which are used by many people.
Moving them to tools also make them open to more users instead of hide in
Documentation folder.This patch moves page-types.c to tools/vm/page-types.c. Also add a
Makefile in tools/vm and fix two coding style problems: a) change const
arrary to 'const char * const', b) change a space to tab for indent.Signed-off-by: Dave Young
