Waitboost (when SLPC is enabled) results in a H2G message. This can result in thousands of messages during a stress test and fill up an already full CTB. There is no need to request for boost if min softlimit is equal or greater than it. v2: Add the tracing back, and check requested freq in the worker thread (Tvrtko) v3: Check requested freq in dec_waiters as well v4: Only check min_softlimit against boost_freq. Limit this optimization for server parts for now. v5: min_softlimit can be greater than boost (Ashutosh) Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221024171108.14373-1-vinay.belgaumkar@intel.com
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.
