When running the GuC the GPU can't be considered idle if the GuC still has contexts pinned. As such, a call has been added in intel_gt_wait_for_idle to idle the UC and in turn the GuC by waiting for the number of unpinned contexts to go to zero. v2: rtimeout -> remaining_timeout v3: Drop unnecessary includes, guc_submission_busy_loop -> guc_submission_send_busy_loop, drop negatie timeout trick, move a refactor of guc_context_unpin to earlier path (John H) v4: Add stddef.h back into intel_gt_requests.h, sort circuit idle function if not in GuC submission mode Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210721215101.139794-16-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 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.
