The Linux kernel user’s and administrator’s guide¶
The following is a collection of user-oriented documents that have been added to the kernel over time. There is, as yet, little overall order or organization here — this material was not written to be a single, coherent document! With luck things will improve quickly over time.
This initial section contains overall information, including the README file describing the kernel as a whole, documentation on kernel parameters, etc.
This section describes CPU vulnerabilities and provides an overview of the possible mitigations along with guidance for selecting mitigations if they are configurable at compile, boot or run time.
Here is a set of documents aimed at users who are trying to track down problems and bugs in particular.
This is the beginning of a section with information of interest to application developers. Documents covering various aspects of the kernel ABI will be found here.
The rest of this manual consists of various unordered guides on how to configure specific aspects of kernel behavior to your liking.
