Add the coefficients for the CPU frequencies to aid in frequency scaling. Profiling setup: - freqbench (https://github.com/kdrag0n/freqbench) - LineageOS kernel, android_kernel_google_msm-4.9 - recommended configuration options by freqbench - disabled options that require clang or 32-bit compilers - mmc governor switched from simple_ondemand to powersave Frequency domains: cpu1 cpu6 Offline CPUs: cpu1 cpu2 cpu3 cpu4 cpu5 cpu6 cpu7 Sampling power every 1000 ms Baseline power usage: 445 mW ===== CPU 1 ===== Frequencies: 300 576 748 998 1209 1324 1516 1612 1708 300: 1114 3.7 C/MHz 43 mW 11.6 J 25.8 I/mJ 269.4 s 576: 2138 3.7 C/MHz 51 mW 7.1 J 42.2 I/mJ 140.3 s 748: 2780 3.7 C/MHz 67 mW 7.3 J 41.3 I/mJ 107.9 s 998: 3706 3.7 C/MHz 73 mW 5.9 J 51.1 I/mJ 80.9 s 1209: 4490 3.7 C/MHz 86 mW 5.7 J 52.2 I/mJ 66.8 s 1324: 4918 3.7 C/MHz 90 mW 5.5 J 54.6 I/mJ 61.0 s 1516: 5631 3.7 C/MHz 103 mW 5.5 J 54.9 I/mJ 53.3 s 1612: 5987 3.7 C/MHz 109 mW 5.5 J 55.0 I/mJ 50.1 s 1708: 6344 3.7 C/MHz 126 mW 5.9 J 50.5 I/mJ 47.3 s ===== CPU 6 ===== Frequencies: 300 652 825 979 1132 1363 1536 1747 1843 1996 300: 1868 6.2 C/MHz 53 mW 8.5 J 35.2 I/mJ 160.6 s 652: 4073 6.2 C/MHz 96 mW 7.1 J 42.4 I/mJ 73.7 s 825: 5132 6.2 C/MHz 117 mW 6.9 J 43.7 I/mJ 58.5 s 979: 6099 6.2 C/MHz 151 mW 7.4 J 40.4 I/mJ 49.2 s 1132: 7071 6.2 C/MHz 207 mW 8.8 J 34.1 I/mJ 42.4 s 1363: 8482 6.2 C/MHz 235 mW 8.3 J 36.1 I/mJ 35.4 s 1536: 9578 6.2 C/MHz 287 mW 9.0 J 33.3 I/mJ 31.3 s 1747: 10892 6.2 C/MHz 340 mW 9.4 J 32.0 I/mJ 27.6 s 1843: 11471 6.2 C/MHz 368 mW 9.6 J 31.1 I/mJ 26.2 s 1996: 12425 6.2 C/MHz 438 mW 10.6 J 28.3 I/mJ 24.2 s Signed-off-by: Richard Acayan <mailingradian@gmail.com> Link: https://lore.kernel.org/r/20230802011548.387519-10-mailingradian@gmail.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>
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.
