First commit 5 years ago			`*/`
machine: Explain use of machine and tidy Linuxisms The functions machine.h provides are deliberately using standard functions from a base install of the operating system. This IS intentional. I'd like to be able to modify and reuse this anywhere without having to untangle additional dependencies from machine to machine. 3 years ago

freebsd: thermal here sucks. There are modules for more but it's too much. They should use a decent API and not put things all over the place/name space. 3 years ago			`#if !defined(__linux__)`

FreeBSD: Support multiple batteries. This was much easier than I had reckoned. Having the battery_names array is sadly a necessary evil for now. Use the same logic for all platforms. Tested on FreeBSD. Needs retesting on Linux, macOS and OpenBSD. The price of support multiple operating systems! 4 years ago			`# include <dev/acpica/acpiio.h>`

macros: underflow, overflow, wombling free.... I can see this happening elsewhere, we'll need to use these in other parts where struct members are of varying signage... 3 years ago			`#include "macros.h"`
machine: Include .bogox files for clarity. To make this maintainable (for now), split the machine querying code into separate files. I'd like to be able to modify the file without fear of breaking it here or there. Also, for anyone who wants to make a change or ammendment doing this is cleaner. 3 years ago			`#include "machine.h"`
