When running the rfi_flush test, if the system is loaded, we see two issues: 1. The L1d misses when rfi_flush is disabled increase significantly due to other workloads interfering with the cache. 2. The L1d misses when rfi_flush is enabled sometimes goes slightly below the expected number of misses. To address these, let's relax the expected number of L1d misses: 1. When rfi_flush is disabled, we allow upto half the expected number of the misses for when rfi_flush is enabled. 2. When rfi_flush is enabled, we allow ~1% lower number of cache misses.

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.
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.
