GuC converts the pre-emption timeout and timeslice quantum values into clock ticks internally. That significantly reduces the point of 32bit overflow. On current platforms, worst case scenario is approximately 110 seconds. Rather than allowing the user to set higher values and then get confused by early timeouts, add limits when setting these values. v2: Add helper functions for clamping (review feedback from Tvrtko). v3: Add a bunch of BUG_ON range checks in addition to the checks already in the clamping functions (Tvrtko) Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221006213813.1563435-2-John.C.Harrison@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.
