The Baytrail SOC, with its Silvermont core, has some unique properties:

Add the "--show" and "--hide" cmdline parameters.
By default, turbostat shows all columns.
turbostat --hide counter_list
will continue showing all columns, except for those listed.
turbostat --show counter_list
will show _only_ the listed columns
These features work for built-in counters, and have no effect
on columns added with the --add parameter.

When --add was used more than once, overflowed buffers
caused some counters to be stored on top of others,
corrupting the results. Simplify the code by simply
reserving space for up to 16 added counters per each
cpu, core, package.
Per-cpu added counters were being printed only per-core.

turbostat gives valid results across suspend to idle, aka freeze,
whether invoked in interval mode, or in command mode.
Indeed, this can be used to measure suspend to idle:
turbostat echo freeze > /sys/power/state
But this does not work across suspend to ACPI S3, because the
processor counters, including the TSC, are reset on resume.
Further, when turbostat detects a problem, it does't forgive
the hardware, and interval mode will print *'s from there on out.
Instead, upon detecting counters going backwards, simply
reset and start over.

The RAPL Joules counter is limited in capacity.
Turbostat estimates how soon it can roll-over
based on the max TDP of the processor --
which tells us the maximum increment rate.
eg.
RAPL: 2759 sec. Joule Counter Range, at 95 Watts
So if a sample duration is longer than 2759 seconds on this system,
'**' replace the decimal place in the display to indicate
that the results may be suspect.
But the display had an extra ' ' in this case, throwing off the columns.
Also, the -J "Joules" option appended an extra "time" column
to the display. While this may be useful, it printed the interval time,
which may not be the accurate time per processor. Remove this column,
which appeared only when using '-J',
as we plan to add accurate per-cpu interval times in a future commit.

ACPICA commit bbcb58f7875381d5c7f3d614bad3bc628a3f5cc6
The following build errors can be seen for MacOSX builds:
.../osunixxf.c:882:9: error: 'sem_close' is deprecated [-Werror,-Wdeprecated-declarations]
.../acmacosx.h:122:29: note: expanded from macro 'sem_destroy'
#define sem_destroy sem_close
sem_destroy() issue is caused by the wrong order of the following lines:
#define #sem_destroy sem_close
#include <semaphore.h>
This patch fixes it by removing the buggy re-definitiion. Lv Zheng.
Linux is not affected by this change.

ACPICA commit de5b9c0ef1ccb264cbe57c88f6dd3fbf8229f907
The following build errors can be seen for MacOSX builds:
.../osunixxf.c:829:42: error: 'tmpnam' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of tmpnam(3), it is highly recommended that you use mkstemp(3) instead. [-Werror,-Wdeprecated-declarations]
Using of temporal file name functions can easily result in bus errors on
MacOSX. This patch implements anonymous semaphore using an automatic
increasing number. Lv Zheng.

Consolidate multiple versions of strtoul64 to one common version.
limit possible bases to either 10 or 16.
Handles both implicit and explicit conversions.
Added a 2-character ascii-to-hex function for GPEs and buffers.
Adds a new file, utstrtoul64.c

ACPICA commit 189429fb7d06cdb89043ae32d615faf553467f1d
This patch follows new ACPICA design, eliminates old portable OSLs, and
implements fopen/fread/fwrite/fclose/fseek/ftell for GNU EFI
environment. This patch also eliminates acpi_log_error(), convering them
into fprintf(stderr)/perror(). Lv Zheng.

ACPICA commit d261d40ea168f8e4c4e3986de720b8651c4aba1c
This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf()
support for OSPMs that have ACPI_USE_SYSTEM_CLIBRARY defined but do not
have ACPI_USE_STANDARD_HEADERS defined.
-iwithprefix include is required to include <stdarg.h> which contains
compiler specific implementation of vargs when -nostdinc is specified.
-fno-builtin is required for GCC to avoid optimization performed printf().
This optimization cannot be automatically disabled by specifying -nostdlib.
Please refer to the first link below for the details. However, the build
option changes do not affect Linux kernel builds and are not included.
Lv Zheng.

ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09
When /Za is specified, headers of some Windows SDKs contain bugs breaking
VC builds, and MSVC9's default SDK is one of such header-buggy library.
In order to solve this issue, many VC developers stop using /Za. However
we've been asked to have this fixed without removing /Za.
In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h>
to be the last standard file included by every source file in the projects.
This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this
issue can be fixed by ensuring that "acapps.h" is always the last standard
file included by all of the ACPICA source files. This is in fact also a
useful cleanup because applications can only include one header (e.x.,
acpidump.h) instead of including acapps.h separately. Lv Zheng.
Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d
EFI header should use standard C library stuffs (integer types and IO
handles) rather than implementing such standard stuffs.
This patch fixes this issue by:
1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n;
2. Defining EFI types using standard integer types and standard IO handles;
3. Tuning header inclusion order and environment definition order;
4. Removing wrong standard header inclusion from ACPICA core files;
5. Moving several application headers from acpidump.h to acenv.h.
This patch corrects some of them. Lv Zheng.
Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.
