[PATCH] arm64/mpam: Add build dependencies for CONFIG_RESCTRL_IOMMU
by Zeng Heng 18 Nov '25

18 Nov '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC03L1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git/commit/?h=m… -------------------------------- On the ARM64 architecture, the CONFIG_RESCTRL_IOMMU actually depends on the CONFIG_ARM_SMMU_V3, which allows to bind SMMU iommu_groups with resctrl groups. Therefore, add this build dependency in Kconfig. Additionally, to avoid compilation errors due to re-definitions in the include/linux/resctrl.h header file when the CONFIG_RESCTRL_IOMMU is disabled, add the build switch for resctrl_arch_*_iommu_closid_rmid().

[PATCH OLK-6.6] arm64/mpam: Add build dependencies for CONFIG_RESCTRL_IOMMU
by Zeng Heng 18 Nov '25

18 Nov '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID65P3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git/commit/?h=m… -------------------------------- On the ARM64 architecture, the CONFIG_RESCTRL_IOMMU actually depends on the CONFIG_ARM_SMMU_V3, which allows to bind SMMU iommu_groups with resctrl groups. Therefore, add this build dependency in Kconfig. Additionally, to avoid compilation errors due to re-definitions in the include/linux/resctrl.h header file when the CONFIG_RESCTRL_IOMMU is disabled, add the build switch for resctrl_arch_*_iommu_closid_rmid().
