It turned out I hadn't enabled CHECKPOINT_RESTORE in the kernel I was
testing. Add a decoding of errno to the testcase to make that obvious.

Sometimes a test kernel will crash or hang on reboot (this is even more
apparent when testing a config without CGROUPS on a box running
systemd). When this happens, on the next iteration of installing a
kernel, ktest will fail when it tries to install.
Have ktest do a check to see if the target can be connected to via ssh
before it tries to install. If it can't connect, then reboot again.
This time the reboot will fail because it can't connect and will force a
power cycle.

Commit fb16d891 "kconfig: replace 'oldnoconfig' with 'olddefconfig', and
keep the old name", changed ktest's default config update from
oldnoconfig to olddefconfig without adding oldnoconfig as a backup.
The make oldnoconfig works much better than its backup of:
yes '' | make oldconfig
But due to this change, and the fact that ktest is used to build lots of
older kernels (and for bisects), it forgoes the oldnoconfig completely.

The turbostat Makefile is pretty simple, its output is placed in the

not use the more familiar CROSS_COMPILE. By making a few minor changes
these limitations are removed while leaving the default behavior
matching what it used to be.
Example build with these changes:
make CROSS_COMPILE=i686-wrs-linux-gnu- DESTDIR=/tmp install
or from the tools directory

Show power in Watts and temperature in Celsius
when hardware support is present.
Intel's Sandy Bridge and Ivy Bridge processor generations support RAPL
(Run-Time-Average-Power-Limiting). Per the Intel SDM
(Intel® 64 and IA-32 Architectures Software Developer Manual)
RAPL provides hardware energy counters and power control MSRs
(Model Specific Registers). RAPL MSRs are designed primarily
as a method to implement power capping. However, they are useful
for monitoring system power whether or not power capping is used.
In addition, Turbostat now shows temperature from DTS
(Digital Thermal Sensor) and PTM (Package Thermal Monitor) hardware,
if present.
As before, turbostat reads MSRs, and never writes MSRs.
New columns are present in turbostat output:
The Pkg_W column shows Watts for each package (socket) in the system.
On multi-socket systems, the system summary on the 1st row shows the sum
for all sockets together.
The Cor_W column shows Watts due to processors cores.
Note that Core_W is included in Pkg_W.
The optional GFX_W column shows Watts due to the graphics "un-core".
Note that GFX_W is included in Pkg_W.
The optional RAM_W column on server processors shows Watts due to DRAM DIMMS.
As DRAM DIMMs are outside the processor package, RAM_W is not included in Pkg_W.
The optional PKG_% and RAM_% columns on server processors shows the % of time
in the measurement interval that RAPL power limiting is in effect on the
package and on DRAM.
Note that the RAPL energy counters have some limitations.
First, hardware updates the counters about once every milli-second.
This is fine for typical turbostat measurement intervals > 1 sec.
However, when turbostat is used to measure events that approach
1ms, the counters are less useful.
Second, the 32-bit energy counters are subject to wrapping.
For example, a counter incrementing 15 micro-Joule units
on a 130 Watt TDP server processor could (in theory)
roll over in about 9 minutes. Turbostat detects and handles
up to 1 counter overflow per measurement interval.
But when the measurement interval exceeds the guaranteed
counter range, we can't detect if more than 1 overflow occured.
So in this case turbostat indicates that the results are
in question by replacing the fractional part of the Watts
in the output with "**":
Pkg_W Cor_W GFX_W
3** 0** 0**
Third, the RAPL counters are energy (Joule) counters -- they sum up
weighted events in the package to estimate energy consumed. They are
not analong power (Watt) meters. In practice, they tend to under-count
because they don't cover every possible use of energy in the package.
The accuracy of the RAPL counters will vary between product generations,
and between SKU's in the same product generation, and with temperature.
turbostat's -v (verbose) option now displays more power and thermal configuration
information -- as shown on the turbostat.8 manual page.
For example, it now displays the Package and DRAM Thermal Design Power (TDP):
cpu0: MSR_PKG_POWER_INFO: 0x2f064001980410 (130 W TDP, RAPL 51 - 200 W, 0.045898 sec.)
cpu0: MSR_DRAM_POWER_INFO,: 0x28025800780118 (35 W TDP, RAPL 15 - 75 W, 0.039062 sec.)
cpu8: MSR_PKG_POWER_INFO: 0x2f064001980410 (130 W TDP, RAPL 51 - 200 W, 0.045898 sec.)

If an MSR based monitor is run in parallel this is not needed. This is the
default case on all/most Intel machines.
But when only sysfs info is read via cpupower monitor -m Idle_Stats (typically
the case for non root users) or when other monitors are PCI based (AMD),
Idle_Stats, read from sysfs can be totally bogus:
cpupower monitor -m Idle_Stats
PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N
0| 0| 0| 0.00| 0.00| 0.24| 99.81
0| 0| 32| 0.00| 0.00| 0.00| 100.7

0| 18| 76| 0.00| 0.00| 0.00| 0.00
...
With the -c option all cores are woken up and the kernel
did update cpuidle statistics before reading out sysfs.
This causes some overhead. Therefore avoid if possible, use
if needed:
cpupower monitor -c -m Idle_Stats
PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N
0| 0| 0| 0.00| 0.00| 0.00| 100.2

The pkgs member of cpupower_topology is being used as the number of
cpu packages. As the comment in get_cpu_topology notes, the package ids
are not guaranteed to be contiguous. So, simply setting pkgs to the value
of the highest physical_package_id doesn't actually provide a count of
the number of cpu packages. Instead, calculate pkgs by setting it to
the number of distinct physical_packge_id values which is pretty easy
to do after the core_info structs are sorted. Calculating pkgs this
way also has the nice benefit of getting rid of a sign comparison warning
that GCC 4.6 was reporting.

The cpu_info member of cpupower_topology was being declared as an unnamed
structure. This member was then being malloced using the size of the
parent cpupower_topology * the number of cpus. This works
because cpu_info is smaller than cpupower_topology. However, there is
no guarantee that will always be the case. Making cpu_info its own
top level structure (named cpuid_core_info) allows for mallocing the actual
size of this structure. This also lets us get rid of a redefinition of
the structure in topology.c with slightly different field names.

Fix a variety of issues with sysfs_topology_read_file:
* The return value of sysfs_topology_read_file function was not properly

* The function was reading int valued sysfs variables and then returning
their value. So, even if a function was trying to check the return value
of this function, a caller would not be able to tell an failure code apart
from reading a negative value. This also conflicted with the comment on the

* The function was parsing int valued sysfs values with strtoul instead of

Turbostat assumed if it can't migrate to a CPU, then the CPU
must have gone off-line and turbostat should re-initialize
with the new topology.
But if turbostat can not migrate because it is restricted by
a cpuset, then it will fail to migrate even after re-initialization,
resulting in an infinite loop.
Spit out a warning when we can't migrate
and endure only 2 re-initialize cycles in a row

Make perf build for x86 once the UAPI disintegration patches for that arch
have been applied by adding the appropriate -I flags - in the right order -
and then converting some #includes that use ../.. notation to find main kernel
headerfiles to use <asm/foo.h> and <linux/foo.h> instead.
Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include.
This makes sure we get the userspace version of the pt_regs struct. Ideally,
we wouldn't have the latter -I flag at all, but unfortunately we want
asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI -
at least not for x86. I wonder if the bits outside of the __KERNEL__ guards
*should* be transferred there.
I note also that perf seems to do its dependency handling manually by listing
all the header files it might want to use in LIB_H in the Makefile. Can this
be changed to use -MD?
Note that to do make this work, we need to export and UAPI disintegrate
linux/hw_breakpoint.h, which I think should've been exported previously so that
perf can access the bits. We have to do this in the same patch to maintain
bisectability.

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.
To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).
For example, take perf. This is found in tools/perf/. Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where
we run the build from, we see:
make run in dir $(OUTPUT) dir
======================= ==================
linux ~/zebra/tools/perf/
linux/tools ~/zebra/perf/
linux/tools/perf ~/zebra/
and if O= is not set, we get:
make run in dir $(OUTPUT) dir
======================= ==================
linux linux/tools/perf/
linux/tools linux/tools/perf/
linux/tools/perf linux/tools/perf/
The output directories are created by the descend function if they don't
already exist.

To clarify what is being tested, instead of assuming that evsel->leader
== NULL means either an 'isolated' evsel or a 'group leader'.

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.
To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).
For example, take perf. This is found in tools/perf/. Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where
we run the build from, we see:
make run in dir $(OUTPUT) dir
======================= ==================
linux ~/zebra/tools/perf/
linux/tools ~/zebra/perf/
linux/tools/perf ~/zebra/
and if O= is not set, we get:
make run in dir $(OUTPUT) dir
======================= ==================
linux linux/tools/perf/
linux/tools linux/tools/perf/
linux/tools/perf linux/tools/perf/
The output directories are created by the descend function if they don't
already exist.

Define a Makefile function that can be called with $(call ...) to wrap
the subdir make invocations in tools/Makefile.
This will allow us in the next patch to insert bits in there to honour
O= flags when called from the top-level Makefile.

Sometimes we need to know when the progress bar should disappear.
Checking curr >= total wasn't enough since there're cases not met that
condition for the last call.
So add a new ->finish callback to identify this explicitly. Currently
only GTK frontend needs it.

Implement progress update function for GTK2 front end.
Note that since it will be called before gtk main loop so that we should
call gtk event loop handler directly.
