Linux kernel source tree

As multi-GT VF post-migration recovery can run in parallel on different workqueues, but both GTs point to the same GGTT, only one GT needs to shift the GGTT. However, both GTs need to know when this step has completed. To coordinate this, perform the GGTT shift under the GGTT lock. With shift being done under the lock, storing the shift value becomes unnecessary. In addition to above, move the GGTT VF config from the GT to the tile. v3: - Update commmit message (Tomasz) v4: - Move GGTT values to tile state (Michal) - Use GGTT lock (Michal) v5: - Only take GGTT lock during recovery (CI) - Drop goto in vf_get_submission_cfg (Michal) - Add kernel doc around recovery in xe_gt_sriov_vf_query_config (Michal) v7: - Drop recovery variable (Michal) - Use _locked naming (Michal) - Use guard (Michal) v9: - Break LMEM changes into different patch (Michal) - Fix layering (Michal) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://lore.kernel.org/r/20251008214532.3442967-15-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.
