According to [0], the contribution field for each cooling-device express their relative power efficiency. Higher weights express higher power efficiency. Weighting is relative such that if each cooling device has a weight of 1 they are considered equal. This is particularly useful in heterogeneous systems where two cooling devices may perform the same kind of compute, but with different efficiency. [0] Documentation/thermal/power_allocator.txt According to Mediatek IC designer, the power efficiency ratio between the LITTLE core cluster (cooling-device cpu0) and big core cluster (cooling-device cpu1) is around 3:1 (3072:1024).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
