A reference to a UAR is required to generate CQ or EQ doorbells. Since CQ or EQ doorbells can all be generated using the same UAR area without any effect on performance, we are just getting a reference to any available UAR, If one is not available we allocate it but we don't waste the blue flame registers it can provide and we will use them for subsequent allocations. We get a reference to such UAR and put in mlx5_priv so any kernel consumer can make use of it.

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.
