The kernel now supports the disabling of branch tracing, however the decoder assumes branch tracing is always enabled. Pass through a parameter to indicate whether branch tracing is enabled and use it to avoid cases when the decoder is expecting branch packets. There are 2 such cases. First, FUP packets which can bind to an IP even when there is no branch tracing. Secondly, the decoder will try to use branch packets to find an IP to start decoding or to recover from errors.

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.
