Linux kernel source tree

If an exec queue is idle, there is no need to issue a schedule disable to the GuC when suspending the queue’s execution. Opportunistically skip this step if the queue is idle and not a parallel queue. Parallel queues must have their scheduling state flipped in the GuC due to limitations in how submission is implemented in run_job(). Also if all pagefault queues can skip the schedule disable during a switch to dma-fence mode, do not schedule a resume for the pagefault queues after the next submission. v2: - Don't touch the LRC tail is queue is suspended but enabled in run_job (CI) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patch.msgid.link/20251212182847.1683222-5-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.
