Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as per hardware design, if DMA-able range contains all 64-bits set (0xFFFFFFFF-FFFFFFFF) then it results in a firmware fault. E.g. SGE's start address is 0xFFFFFFFF-FFFF000 and data length is 0x1000 bytes. when HBA tries to DMA the data at 0xFFFFFFFF-FFFFFFFF location then HBA will fault the firmware. Driver will set 63-bit DMA mask to ensure the above address will not be used.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
