Enable Quality of Service(QoS) support to speed up interrupt service routine handle. Sometimes, a gic interrupt will be generated after SPI transmission, but at this time the CPU is in an idle state and the processing handler will be very slow. It takes time to exit the idle state and then become active. This will cause the SPI handler to execute slowly and cause SPI transfer timeouts.

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.
