[ Upstream commit e5f4e68eed85fa8495d78cd966eecc2b27bb9e53 ]
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 83.49 4531 66 112.71 112.06 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 99.61 4481 69 124.90 124.25 0x00000000 99.61 4481 71 124.92 124.25 0x00000000 59.35 4479 42 75.03 74.37 0x00000000 0.00 4800 42 1.39 0.73 0x00000000 0.00 4801 42 1.42 0.76 0x00000000
