The current script does record qemu diagnostics, but the user has to
know where to look for them. This commit therefore puts them into the
Warnings file so that kvm-recheck.sh will display them. This change is
especially useful if you are in the habit of killing the qemu process
when you realize that you messed something up, but then later on wonder
why the process terminated early.

In a normal torture-test run, the script inherits its environment
variables, but this does not work when producing a script that is
to run later. Therefore, definitions and exports are prepended to
a dryrun script but not to a script that is run immediately. This
commit reconciles this by placing definitions and exports at the
beginning of the script in both cases.

The torture tests need to set specific values for their respective
Kconfig options (e.g., CONFIG_LOCK_TORTURE_TEST), and must therefore
filter any conflicting definitions from the Kconfig fragment
file. Unfortunately, the code in kvm-build.sh was looking only for
CONFIG_RCU_TORTURE_TEST. This commit therefore handles the general case
of CONFIG_[A-Z]*_TORTURE_TEST.

I believe that passing pid (instead of tid) as the 3rd arg of the
machine__find*_thread() was to find a main thread so that it can
search proper map group for symbols. However with the map sharing

It fixes a bug when each thread has different name, it only reports a

Currently perf record doesn't propagate the exit status of a workload
given by the command line. But sometimes it'd useful if it's
propagated so that a monitoring script can handle errors
appropriately.
To do that, it moves most of logic out of the exit handlers and run
them directly in the __cmd_record(). The only thing needs to be done
in the handler is propagating terminating signal so that the shell can
terminate its loop properly when Ctrl-C was pressed. Also it cleaned
up the resource management code in record__exit().
With this change, perf record returns the child exit status in case of
normal termination and send signal to itself when terminated by signal.
Example run of Stephane's case:
$ perf record true && echo yes || echo no
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.013 MB perf.data (~589 samples) ]
yes
$ perf record false && echo yes || echo no
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.013 MB perf.data (~589 samples) ]
no
Jiri's case (error in parent):
$ perf record -m 10G true && echo yes || echo no
rounding mmap pages size to 17179869184 bytes (4194304 pages)

no
$ ulimit -n 6
$ perf record sleep 1 && echo yes || echo no
failed to create 'go' pipe: Too many open files
Couldn't run the workload!
no
And Peter's case (interrupted by signal):
$ while :; do perf record sleep 1; done
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.014 MB perf.data (~593 samples) ]

In output of perf sched map, any shortname of thread will be explained
at the first time when it appear.
Example:
*A0 228836.978985 secs A0 => perf:23032
*. A0 228836.979016 secs B0 => swapper:0
. *C0 228836.979099 secs C0 => migration/3:22
*A0 . C0 228836.979115 secs
A0 . *. 228836.979115 secs
But B0, which is explained as swapper:0 did not appear in the
left part of output. Instead, we use '.' as the shortname of
swapper:0. So the comment of "B0 => swapper:0" is not easy to
understand.
This patch clarify the output of perf sched map with not allocating
one letter-number shortname for swapper:0 and print ". => swapper:0"
as the explanation for swapper:0.
Example:
*A0 228836.978985 secs A0 => perf:23032

It is reported that there are buggy BIOSes in the world: AMI uses an XSDT
compiler for early BIOSes, this compiler will generate XSDT with a NULL
entry. The affected BIOS versions are "AMI BIOS F2-F4".
Original solution on Linux is to use an alternative heathy root table
instead of the ill one. This commit is:
Commit: 671cc68dc61f029d44b43a681356078e02d8dab8
Subject: ACPICA: Back port and refine validation of the XSDT root table.
This is an example of such XSDT dumped from B85-HD3 (AMI F3 BIOS):
[000h 0000 4] Signature : "XSDT" [Extended System Description Table]
[004h 0004 4] Table Length : 00000074
[008h 0008 1] Revision : 01
[009h 0009 1] Checksum : 18
[00Ah 0010 6] Oem ID : "ALASKA"
[010h 0016 8] Oem Table ID : "A M I"
[018h 0024 4] Oem Revision : 01072009
[01Ch 0028 4] Asl Compiler ID : "AMI "
[020h 0032 4] Asl Compiler Revision : 00010013
[024h 0036 8] ACPI Table Address 0 : 00000000BA5F8180
[02Ch 0044 8] ACPI Table Address 1 : 00000000BA5F8290
[034h 0052 8] ACPI Table Address 2 : 00000000BA5F8308
[03Ch 0060 8] ACPI Table Address 3 : 00000000BA5F8848
[044h 0068 8] ACPI Table Address 4 : 00000000BA5F9320
[04Ch 0076 8] ACPI Table Address 5 : 00000000BA5F9360
[054h 0084 8] ACPI Table Address 6 : 00000000BA5F9398
[05Ch 0092 8] ACPI Table Address 7 : 00000000BA5F9708
[064h d100 8] ACPI Table Address 8 : 00000000BA5FC9A8
[06Ch 0108 8] ACPI Table Address 9 : 0000000000000000
But according to the bug report, the XSDT in fact is not broken. In the
above XSDT, ACPI Table Address 1-8 contains the same value as RSDT. The
differences can only be seen on the following 2 entries:
1. The first entry points to a FADT whose Revision is 5 while the first
entry in RSDT points to a FADT whose Revision is 2.
The FADT dumped from the address indicated by the first entry of XSDT:
FACP @ 0x00000000BA5F8180
0000: 46 41 43 50 0C 01 00 00<05>4B 41 4C 41 53 4B 41 FACP.....KALASKA
...
The FADT dumped from the address indicated by the first entry of RSDT:
FACP @ 0x00000000BA5ED0F0
0000: 46 41 43 50 84 00 00 00<02>A7 41 4C 41 53 4B 41 FACP......ALASKA
...
2. The last entry is a NULL terminator.
According to the test result, the Revision 5 FADT is accessible. Thus the
original solution turns out to be a work around that is preventing the
higher revision tables to be used for such platforms (they are all x86-64
platforms, and should use XSDT and higher revision FADT).
This patch offers a new solution, where a sanity check is performed before
installing a table address from XSDT. If the entry is NULL, it is simply
discarded.
Note that, this patch doesn't remove the original solution, so for Linux
kernel, this commit is actually a no-op, but it allows acpidump to be
working on such platforms. By doing so, we allow another easy revertable
commit to enable this feature so that when that commit is reverted, the
useful sanity check will not be affected. Lv Zheng.

This patch adds "-x" and "-x -x" options to disable XSDT for acpidump.
The single "-x" can be used to stop using XSDT, RSDT will be forced to find
static tables, note that XSDT will still be dumped. The double "-x" can
stop dumping XSDT, which is useful when the XSDT address reported by RSDP
is pointing to an invalid address.
It is reported there are platforms having broken XSDT shipped, acpidump
will stop working while accessing such XSDT. This patch adds new option so
that users can force acpidump to dump tables listed in the RSDT. Lv Zheng.

This patch fixes an issue that the while loop is not needed as fread()
should return exact the bytes of expected.
The patch is tested by runing diff against the output of "-c" mode and
the normal mode, and only finds the following differences:
1. table addresses: the "-c" mode will always fill 0x0000000000000000 for
the address.
2. RSDP/RSDT/XSDT: there is no generation of such tables for "-c" mode.
So the test result shows the fix is valid. Lv Zheng.

The command "cpupower frequency-info" can be used when using cpupower to
monitor and test processor behaviour to determine if the processor is
behaving as expected. This data can be compared to the output of
/proc/cpuinfo or the output of
/sys/devices/system/cpu/cpuX/cpufreq/scaling_available_frequencies
to determine if the cpu is in an expected state.
When doing this I noticed comparison test failures due to the way the
data is displayed in cpupower. For example,
[root@intel-s3e37-02 cpupower]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

shows very different values for the available frequency steps. The cpupower
output rounds off values at 2 decimal points and this causes problems with
test scripts. For example, with the data above,
1.064 is 1.06
1.197 is 1.20
1.596 is 1.60
1.995 is 2.00
2.128 is 2.13
and most confusingly,
2.261 is 2.26
2.262 is 2.26
Truncating these values serves no real purpose other than making the output
pretty. Since the default has been to round off these values I am adding
a -n/--no-rounding option to the cpupower utility that will display the
data without rounding off the still significant digits.

The Intel 64 and IA-32 Architectures Software Developer's Manual says
that TjMax is stored in bits 23:16 of MSR_TEMPERATURE TARGET (0x1a2).
That's 8 bits, not 7, so it must be masked with 0xFF rather than 0x7F.
The manual has no mention of which values should be considered valid,
which kind of implies that they all are. Arbitrarily discarding values
outside a specific range is wrong. The upper range check had to be
fixed recently (commit 144b44b1) and the lower range check is just as
wrong. See bug #75071:
https://bugzilla.kernel.org/show_bug.cgi?id=75071
There are many Xeon processor series with TjMax of 70, 71 or 80
degrees Celsius, way below the arbitrary 85 degrees Celsius limit.
There may be other (past or future) models with even lower limits.
So drop this arbitrary check. The only value that would be clearly
invalid is 0. Everything else should be accepted.
After these changes, turbostat is aligned with what the coretemp
driver does.

Into new perf-sys.h header.
The main reason is to separate system specific perf data
from perf tool stuff, so it could be used in small test
programs, as requested Peter:
http://lkml.kernel.org/r/20140502115201.GI30445@twins.programming.kicks-ass.net
This separation makes the perf.h header more clear.
