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).

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 recent patch that implements table printing on a keypress introduced a
regression - turbostat prints the table almost continuously if it is run from a
daemon program.
The problem is also easy to reproduce like this:
echo | turbostat
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

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.

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.

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.

Most places use pwd and rely on $PATH lookup. Moving the remaining
absolute path /bin/pwd users over for consistency.
Also, a reason for doing /bin/pwd -> pwd instead of the other way around
is because I believe build systems should make little assumptions on
host filesystem layout. Case in point, we do this kind of patching
already in NixOS.

The kernel-tools-lib rpm is installing the library to /usr/lib64, and not
/usr/lib as the cpupower Makefile is doing in the kernel tree. This
resulted in a conflict between the two libraries. After looking at how
other tools installed libraries, and looking at the perf code in
tools/perf it looks like installing to /usr/lib64 for 64-bit arches is the
correct thing to do.
Checks with 'ldd cpupower' on SLES, RHEL, Fedora, and Ubuntu result in
the correct binary AFAICT:
[root@testsystem cpupower]# ldd cpupower | grep cpupower
libcpupower.so.0 => /lib64/libcpupower.so.0 (0x00007f1dab447000)
Commit ac5a181d06 ("cpupower: Add cpuidle parts into library") added a
new cpupower library version. On Fedora, executing the cpupower binary
then resulted in this error
[root@testsystem cpupower]# ./cpupower monitor
./cpupower: symbol lookup error: ./cpupower: undefined symbol:
get_cpu_topology
64-bit libraries should be installed to /usr/lib64, and other libraries
should be installed to /usr/lib.
This code was taken from the perf Makefile.config which supports /usr/lib
and /usr/lib64.

'cpupower frequency-info -ln' returns kHz values on systems with MHz range
minimum CPU frequency range. For example, on a 800MHz to 4.20GHz system
the command returns
hardware limits: 800000 MHz - 4.200000 GHz
The code that causes this error can be removed. The next else if clause
will handle the output correctly such that
hardware limits: 800.000 MHz - 4.200000 GHz
is displayed correctly.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

I thought commit 8e9b466799 ("kbuild: use $(abspath ...) instead of
$(shell cd ... && /bin/pwd)") was a safe conversion, but it changed
the behavior.
$(abspath ...) / $(realpath ...) does not expand shell special
characters, such as '~'.
Here is a simple Makefile example:
---------------->8----------------
$(info /bin/pwd: $(shell cd ~/; /bin/pwd))
$(info abspath: $(abspath ~/))
$(info realpath: $(realpath ~/))
all:
@:
---------------->8----------------
$ make
/bin/pwd: /home/masahiro
abspath: /home/masahiro/workspace/~
realpath:
This can be a real problem if 'make O=~/foo' is invoked from another
Makefile or primitive shell like dash.
This commit partially reverts 8e9b466799.

Kbuild conventionally uses $(shell cd ... && /bin/pwd) idiom to get
the absolute path of the directory because GNU Make 3.80, the minimal
supported version at that time, did not support $(abspath ...) or
$(realpath ...).
Commit 37d69ee308 ("docs: bump minimal GNU Make version to 3.81")
dropped the GNU Make 3.80 support, so we are now allowed to use those
make-builtin helpers.
This conversion will provide better portability without relying on
the pwd command or its location /bin/pwd.
I am intentionally using $(realpath ...) instead $(abspath ...) in
some places. The difference between the two is $(realpath ...)
returns an empty string if the given path does not exist. It is
convenient in places where we need to error-out if the makefile fails
to create an output directory.

ACPICA commit 343fc31840d40c06001f3b170ee5bcdfd3c7f3e0
ACPI spec allows to configure different 32-bit/64-bit table addresses for
DSDT and FACS. And for FACS, it's meaningful to dump both of them as they
are used to support different suspend protocols.
While:
1. on Linux, only 1 instance is supported for DSDT/FACS; and
2. on EFI, the code in osl_get_table() is buggy with special table instances,
causing endless file dump for such tables (reported by Shao Ming in link
#2).
This patch adds DSDT/FACS instance support for Linux/EFI acpidump. Fixed by
Lv Zheng.

ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5
In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit
multiply/shift supports are also required to be implemented. Otherwise,
MSVC complains:
acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul
acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr
Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.
This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.
For Linux kernel, this patch is a functional no-op.
