FSI_SBEFIFO_READ_TIMEOUT_SECONDS ioctl sets the read timeout (in seconds) for the response received by sbefifo device from sbe. The timeout affects only the read operation on current sbefifo device fd. Certain SBE operations can take long time to complete and the default timeout of 10 seconds might not be sufficient to start receiving response from SBE. In such cases, allow the timeout to be set to the maximum of 120 seconds. The kernel does not contain the definition of the various SBE operations, so we must expose an interface to userspace to set the timeout for the given operation.

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.
