Using cluster topology on hybrid CPUs, e.g. Alder Lake, biases the scheduler towards the ATOM cluster as that has more total capacity. Use selection based on CPU priority instead. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmG1xxETHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoWhaEADFlr1l6QwIJs8Bv3Z9u/kkW1fPIoqP aFDrqLiQ/T+gBuS+d7R3YkRf1cICS+gbvv/dw8qx/v6gerUC71tEXxYxvOUqR7QL wX2zFNrhQqBaIKKGnbTHe47pB2+/AlpbXuQ2/j415AHxCxB4fOC1N4VKq0hTUyPu Ubz+QmOHcB0NhAf1jeN9DAlTJgQNbRW6oYYPJDsr+n+WjdlN3IZW/hCxLN1cvnNd NzsDEK1EeuccteoT5btzYy+XB31+WNrZ9afcJgG7goO/zmJfZ1lWAsyjKPocn6dC ozZSvHQhbgJIAwBaZJFyjZocgHTIkdFX6NzlpKaWw05tk984hJJ9pvg4KO5YeNx/ tIehPnkmd9GwwO541+t3DhcbCPQIiKypRZKnXuczkjIuG3t2oD25b1EAqwhoPKGk TEX2o4DjixS3oKUP6khDteQkj8B0qOjeY18eGjBilJ764mRfbL+GRk/NoqVidrnt JWSCPEMM842Y8W7GYfZZZAypqDz9U0yRl+BCKpNDcx3Nr5OSbfkWC/LdvM3LlgIE /a2C6CXIZXgiifTF2PHOmv0O3/VPAtHXZ01ExzZu/MJP0hBUjLrxsj+TwILgociw WLVYnBgCf5XN1rMPmora8P5y+O/UpEYhXbmIFa6HQAQyfc0Ffiof4ZOl5VYf3mNh 1GLB+ByEgCz4ig== =rr0v -----END PGP SIGNATURE----- Merge tag 'sched-urgent-2021-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fix from Thomas Gleixner: "A single fix for the x86 scheduler topology: Using cluster topology on hybrid CPUs, e.g. Alder Lake, biases the scheduler towards the ATOM cluster as that has more total capacity.

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.
