    tools/power turbostat: Fix added raw MSR output · e5f4e68e
    Doug Smythies authored
    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
