Doug Smythies 768b167281 tools/power turbostat: Fix added raw MSR output 
[ Upstream commit e5f4e68eed ]

When using --Summary mode, added MSRs in raw mode always
print zeros. Print the actual register contents.

Example, with patch:

note the added column:
--add msr0x64f,u32,package,raw,REASON

Where:

0x64F is MSR_CORE_PERF_LIMIT_REASONS

Busy%   Bzy_MHz PkgTmp  PkgWatt CorWatt     REASON
0.00    4800    35      1.42    0.76    0x00000000
0.00    4801    34      1.42    0.76    0x00000000
80.08   4531    66      108.17  107.52  0x08000000
98.69   4530    66      133.21  132.54  0x08000000
99.28   4505    66      128.26  127.60  0x0c000400
99.65   4486    68      124.91  124.25  0x0c000400
99.63   4483    68      124.90  124.25  0x0c000400
79.34   4481    41      99.80   99.13   0x0c000000
0.00    4801    41      1.40    0.73    0x0c000000

Where, for the test processor (i5-10600K):

PKG Limit #1: 125.000 Watts, 8.000000 sec
MSR bit 26 = log; bit 10 = status

PKG Limit #2: 136.000 Watts, 0.002441 sec
MSR bit 27 = log; bit 11 = status

Example, without patch:

Busy%   Bzy_MHz PkgTmp  PkgWatt CorWatt     REASON
0.01    4800    35      1.43    0.77    0x00000000
0.00    4801    35      1.39    0.73    0x00000000

98.69   4530    68      133.35  132.69  0x00000000
99.31   4500    67      127.96  127.30  0x00000000
99.63   4483    69      124.91  124.25  0x00000000

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
