Allocate segmented trace buffer if firmware advertises the capability in IOCfacts. Upon driver load, read the trace buffer size from driver page 1, calculate the required segments for trace buffer, and allocate segmented buffers. Each segment is 4096 bytes in size. While posting driver diagnostic buffer to firmware, advertise that trace buffer is segmented.

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 reStructuredText 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.
