This bug is awaiting verification that the linux-aws- fips/6.8.0-1034.36+fips1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-aws-fips' to 'verification-done-noble-linux-aws-fips'. If the problem still exists, change the tag 'verification-needed-noble-linux-aws-fips' to 'verification-failed-noble-linux-aws-fips'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Fixes to commit 918eb5c856f6 ("iommu/arm-smmu-v3: Add in-kernel support for NVIDIA Tegra241 (Grace) CMDQV"), from patchset 2, which were also clean cherry-picks, were added. - Patchset #3's only patch and one fix to it were clean cherry-picks. Noble: Backporting patchset #1 required backporting the patchsets it was built on top of: - All patches from "Update SMMUv3 to the modern iommu API (part 1/3)" (https://lore.kernel.org/all/[email protected]/), except for "iommu/arm-smmu-v3: Hold arm_smmu_asid_lock during all of attach_dev", which is already in the tree. And * "iommu/arm-smmu-v3: Add cpu_to_le64() around STRTAB_STE_0_V", as a fix to "iommu/arm-smmu-v3: Make STE programming independent of the callers". - Parts of "Update SMMUv3 to the modern iommu API (part 2/3)" (https://lore.kernel.org/all/[email protected]/). - All patches from "Make the SMMUv3 CD logic match the new STE design" (part 2a/3) (https://lore.kernel.org/all/[email protected]/). And * "iommu: Introduce iommu_group_mutex_assert()", as pre-req for "iommu/arm-smmu-v3: Move the CD generation for SVA into a function". * "iommu/arm-smmu-v3: Fix access for STE.SHCFG", as pre-req for "iommu/arm-smmu-v3: Add unit tests for arm_smmu_write_entry". * "iommu/arm-smmu-v3: Avoid uninitialized asid in case of error", as a fix for "iommu/arm-smmu-v3: Build the whole CD in arm_smmu_make_s1_cd()". Other pre-reqs for patchset #1 included: - "iommu: Pass domain to remove_dev_pasid() op", as pre-req for "iommu/arm-smmu-v3: Put the SVA mmu notifier in the smmu_domain". - A backport of "iommu: Add ops->domain_alloc_sva()", as pre-req for "iommu/arm-smmu-v3: Convert to domain_alloc_sva()". Patchset #2 was almost all clean cherry-picks except for "iommu/arm-smmu-v3: Add acpi_smmu_iort_probe_model for impl". Additionally, these were needed: * "iommu/arm-smmu-v3: Make the kunit into a module" and "iommu/arm-smmu-v3: Use *-y instead of *-objs in Makefile" to clean cherry-pick "iommu/arm-smmu-v3: Add in-kernel support for NVIDIA Tegra241 (Grace) CMDQV". * "iommu/arm-smmu-v3: add missing MODULE_DESCRIPTION() macro", as a fix for "iommu/arm-smmu-v3: Make the kunit into a module". * Other `Fixes` to commit 918eb5c856f6 ("iommu/arm-smmu-v3: Add in-kernel support for NVIDIA Tegra241 (Grace) CMDQV"), which were clean cherry-picks. Patchset #3's only patch and one fix to it were clean cherry-picks. [Test Case] Compile and boot tested. Tested by AWS. [Where problems could occur] These patches introduce significant refactoring and features to the SMMUv3 driver. Additionally, support to Tegra241's CMDQ-Virtualization is being added.
