Before RESFIX_DONE, all CTs stuck in the H2G queue need to be squashed, as they may contain actions which contain invalid GGTT references or are unnecessary after HW change. Starting the CTs clears all H2Gs in the queue. Any lost H2Gs are resubmitted by the GuC submission state machine. v3: - Don't mess with head / tail values (Michal) v4: - Don't mess with broke (Michal) - Add CTB_H2G_BUFFER_OFFSET (Michal) v5: - Adjust commit message (Tomasz) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://lore.kernel.org/r/20251008214532.3442967-25-matthew.brost@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 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.
