Define helpers and struct members required to record boost info. Boost frequency is initialized to RP0 at SLPC init. Also define num_waiters which can track the pending boost requests. Boost will be done by scheduling a worker thread. This will avoid the need to make H2G calls inside an interrupt context. Initialize the worker function during SLPC init as well. Had to move intel_guc_slpc_init a few lines below to accommodate this. v2: Add a workqueue to handle waitboost v3: Code review comments (Ashutosh) Cc: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211102012608.8609-2-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.
