When cross-compiling cpupower, 64bit detection is done with the host
compiler instead of the cross-compiler and libcpupower.so.0 ends up in
/usr/lib64 instead of /usr/lib for 32bit target. Fix this by moving
64bit detection after CC is defined.

Upgrade bootgraph/sleepgraph to be able to run on python2 and python3.
Both now simply require python, the system can choose which to use.
bootgraph python3 update:
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- open dmesg log and popen in binary, use decode(ascii, ignore)
- sort all html data to allow diff between python versions
- change exception handler to use python3 as instead of comma
sleepgraph python3 update:
- import configparser not ConfigParser (p2 needs python-configparser)
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- handle popen output in binary, use decode(ascii, ignore)
- sort all html/output data to allow diff between python versions
- force gzip open to use text mode, same for file open
- ensure no binary data is written to logs (ascii convert devprops info)
- use codecs library to handle zlib encoding for mcelog data
- remove all uses of python3.7 keyword "async" as members or vars
- assume all FPDT and DMI data is in binary string form
sleepgraph:
- turbostat will be used by default if it's found & the mode is freeze
- a new option "-noturbostat" will disable its use
- fix bug where two callgraphs with the same start time overwrite.
- fix s2idle processing where two suspend/resume_machines occur back2back
- update getexec function to use which first (assuming PATH exists)
- new platforminfo data in log with: lspci, gpe counts, /proc/interrupts
- new data is zipped, b64 encoded, and tacked on the end of ftrace

While descending directories, Kbuild produces objects for modules,
but do not link final *.ko files; it is done in the modpost.
To keep track of modules, Kbuild creates a *.mod file in $(MODVERDIR)
for every module it is building. Some post-processing steps read the
necessary information from *.mod files. This avoids descending into
directories again. This mechanism was introduced in 2003 or so.
Later, commit 551559e13a ("kbuild: implement modules.order") added
modules.order. So, we can simply read it out to know all the modules
with directory paths. This is easier than parsing the first line of
*.mod files.
$(MODVERDIR) has a flat directory structure, that is, *.mod files
are named only with base names. This is based on the assumption that
the module name is unique across the tree. This assumption is really
fragile.
Stephen Rothwell reported a race condition caused by a module name
conflict:
https://lkml.org/lkml/2019/5/13/991
In parallel building, two different threads could write to the same
$(MODVERDIR)/*.mod simultaneously.
Non-unique module names are the source of all kind of troubles, hence
commit 3a48a91901 ("kbuild: check uniqueness of module names")
introduced a new checker script.
However, it is still fragile in the build system point of view because
this race happens before scripts/modules-check.sh is invoked. If it
happens again, the modpost will emit unclear error messages.
To fix this issue completely, create *.mod with full directory path
so that two threads never attempt to write to the same file.
$(MODVERDIR) is no longer needed.
Since modules with directory paths are listed in modules.order, Kbuild
is still able to find *.mod files without additional descending.
I also killed cmd_secanalysis; scripts/mod/sumversion.c computes MD4 hash
for modules with MODULE_VERSION(). When CONFIG_DEBUG_SECTION_MISMATCH=y,
it occurs not only in the modpost stage, but also during directory
descending, where sumversion.c may parse stale *.mod files. It would emit
'No such file or directory' warning when an object consisting a module is
renamed, or when a single-obj module is turned into a multi-obj module or
vice versa.

ASUS WMI driver got a big refactoring in order to support the TUF Gaming
laptops. Besides that, the regression with backlight being permanently off
on various EeePC laptops has been fixed.
Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
Intel PMC core driver has been extended to be ACPI enumerated
if the DSDT provides device with _HID "INT33A1". This allows
to convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
From now on the Intel Speed Select Technology is supported thru
a corresponding driver. This driver provides an access to the features
of the ISST, such as Performance Profile, Core Power, Base frequency and
Turbo Frequency.
Mellanox platform drivers has been refactored and now extended
to support more systems, including new coming ones.
The OLPC XO-1.75 platform is now supported.
CB4063 Beckhoff Automation board is using PMC clocks,
provided via pmc_atom driver, for ethernet controllers in a way
that they can't be managed by the clock driver. The quirk
has been extended to cover this case.
Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more models
based on the same platform.
Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
has been provided. It required some extension of the generic WMI library,
which allows to propagate opaque context to the ->probe() of the
individual drivers.
This release includes debugfs clean up from Greg KH for several drivers
that drop return code check and make debugfs absence or failure non-fatal.
Miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers.

The Intel(R) Speed select technologies contains four features.
Performance profile:An non architectural mechanism that allows multiple
optimized performance profiles per system via static and/or dynamic
adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS
in the documentation.
Base Frequency: Enables users to increase guaranteed base frequency on
certain cores (high priority cores) in exchange for lower base frequency
on remaining cores (low priority cores). aka PBF in the documenation.
Turbo frequency: Enables the ability to set different turbo ratio limits
to cores based on priority. aka FACT in the documentation.
Core power: An Interface that allows user to define per core/tile
priority.
There is a multi level help for commands and options. This can be used
to check required arguments for each feature and commands for the
feature.
To start navigating the features start with

be used :

While setting frequency using cpupower frequency-set command, if we use
'-r' option, it is expected to set frequency for all cpus related to
cpu #i. But it is observed to be missing the last cpu in related cpu
list. This patch fixes the problem.

tools/power/acpi/.gitignore has the following entries:
acpidbg
acpidump
ec
They are intended to ignore the following build artifacts:
tools/power/acpi/acpidbg
tools/power/acpi/acpidump
tools/power/acpi/ec
However, those .gitignore entries are effective not only for the
current directory, but also for any sub-directories.
So, from the point of .gitignore grammar, the following check-in
directories are also considered to be ignored:
tools/power/acpi/tools/acpidbg
tools/power/acpi/tools/acpidump
tools/power/acpi/tools/ec
As the manual gitignore(5) says "Files already tracked by Git are not
affected", this is not a problem as far as Git is concerned.
However, Git is not the only program that parses .gitignore because
.gitignore is useful to distinguish build artifacts from source files.
For example, tar(1) supports the --exclude-vcs-ignore option. As of
writing, this option does not work perfectly, but it intends to create
a tarball excluding files specified by .gitignore.
The issue can be prevented by prefixing the pattern with a slash; the
leading slash means the specified pattern is relative to the current
directory.
Do that for the "include" directory too for consistency and extra
safety.

Pull x86 MDS mitigations from Thomas Gleixner:
"Microarchitectural Data Sampling (MDS) is a hardware vulnerability
which allows unprivileged speculative access to data which is
available in various CPU internal buffers. This new set of misfeatures
has the following CVEs assigned:
CVE-2018-12126 MSBDS Microarchitectural Store Buffer Data Sampling
CVE-2018-12130 MFBDS Microarchitectural Fill Buffer Data Sampling
CVE-2018-12127 MLPDS Microarchitectural Load Port Data Sampling
CVE-2019-11091 MDSUM Microarchitectural Data Sampling Uncacheable Memory
MDS attacks target microarchitectural buffers which speculatively
forward data under certain conditions. Disclosure gadgets can expose
this data via cache side channels.
Contrary to other speculation based vulnerabilities the MDS
vulnerability does not allow the attacker to control the memory target
address. As a consequence the attacks are purely sampling based, but
as demonstrated with the TLBleed attack samples can be postprocessed
successfully.
The mitigation is to flush the microarchitectural buffers on return to
user space and before entering a VM. It's bolted on the VERW
instruction and requires a microcode update. As some of the attacks
exploit data structures shared between hyperthreads, full protection
requires to disable hyperthreading. The kernel does not do that by
default to avoid breaking unattended updates.
The mitigation set comes with documentation for administrators and a
deeper technical view"

The package power can also be read from an MSR. It's not clear exactly
what is included, and whether it's aggregated over all nodes or
reported separately.
It does look like this is reported separately per CCX (I get a single
value on the Ryzen R7 1700), but it might be reported separately per-
die (node?) on larger processors. If that's the case, it would have to
be recorded per node and aggregated for the socket.
Note that although Zen has these MSRs reporting power, it looks like
the actual RAPL configuration (power limits, configured TDP) is done
through PCI configuration space. I have not yet found any public
documentation for this.

Based on the Open-Source Register Reference for AMD Family 17h
Processors Models 00h-2Fh:
https://support.amd.com/TechDocs/56255_OSRR.pdf
These processors report RAPL support in bit 14 of CPUID 0x80000007 EDX,
and the following MSRs are present:
0xc0010299 (RAPL_PWR_UNIT), like Intel's RAPL_POWER_UNIT
0xc001029a (CORE_ENERGY_STAT), kind of like Intel's PP0_ENERGY_STATUS
0xc001029b (PKG_ENERGY_STAT), like Intel's PKG_ENERGY_STATUS
A notable difference from the Intel implementation is that AMD reports
the "Cores" energy usage separately for each core, rather than a
per-package total. The code has been adjusted to handle either case in a
generic way.
I haven't yet enabled collection of package power, due to being unable
to test it on multi-node systems (TR, EPYC).

cpufreq driver creates sysfs file "scaling_boost_frequency" for platforms
which support boost frequency. Cpupower now prints boost frequencies
separately. For few x86 vendors who already have different way to get boost
frequency, will continue to use the existing logic. Rest of the platforms
will rely on "scaling_boost_frequency" file to display boost frequency.

cpupower crashes on VMWare guests. The guests have the AMD PStateDef MSR
(0xC0010064 + state number) set to zero. As a result fid and did are zero
and the crash occurs because of a divide by zero (cof = fid/did). This
can be prevented by checking the enable bit in the PStateDef MSR before
calculating cof. By doing this the value of pstate[i] remains zero and
the value can be tested before displaying the active Pstates.
Check the enable bit in the PstateDef register for all supported families
and only print out enabled Pstates.

turbostat fails on some multi-package topologies because the logical node
enumeration assumes that the nodes are sequentially numbered,
which causes the logical numa nodes to not be enumerated, or enumerated incorrectly.
Use a more robust enumeration algorithm which allows for non-seqential physical nodes.

This patch fixes a regression introduced in
commit 8cb48b32a5 ("tools/power turbostat: track thread ID in cpu_topology")
Turbostat uses incorrect cores number ('topo.num_cores') - its value is count
of logical CPUs, instead of count of physical cores. So it is twice as large as
it should be on a typical Intel system. For example, on a 6 core Xeon system
'topo.num_cores' is 12, and on a 52 core Xeon system 'topo.num_cores' is 104.
And interestingly, on a 68-core Knights Landing Intel system 'topo.num_cores'
is 272, because this system has 4 logical CPUs per core.
As a result, some of the turbostat calculations are incorrect. For example,
on idle 52-core Xeon system when all cores are ~99% in Core C6 (CPU%c6), the
summary (very first) line shows ~48% Core C6, while it should be ~99%.
This patch fixes the problem by fixing 'topo.num_cores' calculation.
Was:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id != -1 (bug!)
Now:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id is not 0
I did not have a chance to test this on an AMD machine, and only tested on a
couple of Intel Xeons (6 and 52 cores).

The code currently assumes each package has exactly one node. This is not
the case for AMD systems and Intel systems with COD. AMD systems also
may re-enumerate each node's core IDs starting at 0 (for example, an AMD
processor may have two nodes, each with core IDs from 0 to 7). In order
to properly enumerate the cores we need to track both the physical and
logical node IDs.
Add physical_node_id to track the node ID assigned by the kernel, and
logical_node_id used by turbostat to track the nodes per package ie) a
0-based count within the package.

The turbostat code only looks at thread_siblings_list to determine if
processing units/threads are on the same the core. This works well on
Intel systems which have a shared L1 instruction and data cache. This
does not work on AMD systems which have shared L1 instruction cache but
separate L1 data caches. Other utilities also check sibling's core ID
to determine if the processing unit shares the same core.
Additionally, the cpu_topology *cpus list used in topology_probe() can
be used elsewhere in the code to simplify things.
Export *cpus to the entire turbostat code, and add Processing Unit/Thread
IDs information to each cpu_topology struct. Confirm that the thread
is on the same core as indicated by thread_siblings_list.

The reason is that we cannot assume that stdin is always a TTY. It can be many
things.
This patch adds fixes the problem by limiting the new keypress functionality to
TTYs only. If stdin is not a TTY, we just sleep for the full interval time.
While on it, clean-up 'do_sleep()' to return no value, as callers do not expect
that anyway.

In turbostat interval mode, a newline typed on standard input
will now conclude the current interval. Data will immediately
be collected and printed for that interval, and the next interval
will be started.
This is similar to the recently added SIGUSR1 feature.
But that is for use by programs, while this is for interactive use.
Signed-off-by: Len Brown <len.brown@intel.com>
Interval-mode turbostat now catches and discards SIGUSR1.
Thus, SIGUSR1 can be used to tell turbostat to cut short
the current measurement interval. Turbostat will then start
the next measurement interval using the regular interval length.
This can be used to give turbostat variable intervals.
Invoke turbostat with --interval LARGE_NUMBER_SEC
and have a program that has permission to send it a SIGUSR1
always before LARGE_NUMBER_SEC expires.
It may also be useful to use "--enable Time_Of_Day_Seconds"
to observe the actual interval length.
Signed-off-by: Len Brown <len.brown@intel.com>
Add a Time_Of_Day_Seconds column showing when measurement
for each row was completed. Units are [sec.subsec] since Epoch,
as reported by gettimeofday(2).
While useful to correlate turbostat output with other tools,
this built-in column is disabled, by default.
Add the "--enable" option to enable such disabled-by-default
built-in columns:
"--enable Time_Of_Day_Seconds"
"--enable usec"
"--enable all", will enable all disabled-by-defauilt built-in counters.
When "--debug" is used, all disabled-by-default columns are enabled,
unless explicitly skipped using "--hide"

Turbostat neglects to display all package C-states for some Skylake Xeon BIOS configurations.
This is due to a typo in the table decoding MSR_PKG_CST_CONFIG_CONTROL (0x000000e2)
Here we fix that typo, according to Intel SDM, vol 4, Table 2-41 -
"MSRs Supported by Intel® Xeon® Processor Scalable Family with DisplayFamily_DisplayModel 06_55H".

Allow the user to override the default trace buffer memory allocation
by adding a command line option to override the default.
The patch also:
Adds a SIGINT (i.e. CTRL C exit) handler,
so that things can be cleaned up before exit.
Moves the postion of some other cleanup from after to
before the potential "No valid data to plot" exit.
Replaces all quit() calls with sys.exit, because
quit() is not supposed to be used in scripts.

Commit 7ed1c1901f (tools: fix cross-compile var clobbering) removed
setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
(acpidump) in power/acpi:
ld: unrecognized option '-D_LINUX'
The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
particular change and let LD be $(CC) again. Note that the old behaviour
was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
the commit 7ed1c1901f. We use $(CC) for that reason.

Currently a number of Makefiles break when used with toolchains that
pass extra flags in CC and other cross-compile related variables (such
as --sysroot).
Thus we get this error when we use a toolchain that puts --sysroot in
the CC var:
~/src/linux/tools$ make iio
[snip]
iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory
#include <unistd.h>
^~~~~~~~~~
This occurs because we clobber several env vars related to
cross-compiling with lines like this:
CC = $(CROSS_COMPILE)gcc
Although this will point to a valid cross-compiler, we lose any extra
flags that might exist in the CC variable, which can break toolchains
that rely on them (for example, those that use --sysroot).
This easily shows up using a Yocto SDK:
$ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi
$ echo $CC
arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard
-mcpu=cortex-a8
--sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi
$ echo $CROSS_COMPILE
arm-poky-linux-gnueabi-
$ echo ${CROSS_COMPILE}gcc
krm-poky-linux-gnueabi-gcc
Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the
--sysroot and other flags that enable us to find the right libraries to
link against, so we can't find unistd.h and other libraries and headers.
Normally with the --sysroot flag we would find unistd.h in the sdk
directory in the sysroot:
$ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h'
[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h
The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not
already set, and it compiles correctly with the above toolchain.
So, generalize the logic that perf uses in the common Makefile and
remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile.
Note that this patch does not fix cross-compile for all the tools (some
have other bugs), but it does fix it for all except usb and acpi, which
still have other unrelated issues.
I tested both with and without the patch on native and cross-build and
there appear to be no regressions.
