Public bug reported: SRU Justification
[Impact] Google requested a Grace-enabled 6.8 kernel for GKE. This patchset targets noble:linux-gke. This requires adding a 64k page size flavor to the existing noble:linux-gke kernel. [Fix] Add select NVIDIA Grace platform patches, similar to what has been done for kernels like noble:linux-azure-nvidia. NVIDIA provides a document [1] listing all of the required and recommended kernel patches for Grace enablement. Version 11 April 25, 2025 of the document was used when preparing this patchset as was version Ubuntu-azure-nvidia-6.8.0-1016.17 of the noble:linux-azure-nvidia kernel. Add a 64k page size flavor to noble:linux-gke. [1] https://docs.nvidia.com/grace-patch-config-guide.pdf [Test Plan] Boot testing on arm64/64k pages in house. Further testing will be done by Google in their Grace-enabled environment once available. [Regression potential] The regression potential is considered moderate due to the number of patches involved and the breadth of the changes. The changes affect pte, perf, PCI, cpufreq, ACPI, mmu, coresight, and other kernel subsystems. ** Affects: linux-gke (Ubuntu) Importance: Undecided Status: New ** Affects: linux-gke (Ubuntu Noble) Importance: Undecided Assignee: Tim Whisonant (tswhison) Status: New ** Description changed: SRU Justification [Impact] Google requested a Grace-enabled 6.8 kernel for GKE.
