When building with clang 12 and CONFIG_ARM_SMMU_V3=y, we observe the following build error:drivers/passthrough/arm/smmu-v3.c:1408:20: error: unused function 'arm_smmu_disable_pasid' [-Werror,-Wunused-function] static inline void arm_smmu_disable_pasid(struct arm_smmu_master *master) { } ^ arm_smmu_disable_pasid is not currently called from anywhere in Xen, but it is inside a section of code guarded by CONFIG_PCI_ATS, which may be helpful in the future if the PASID feature is to be implemented. Add the attribute __maybe_unused to the function. Signed-off-by: Stewart Hildebrand <stewart.hildebr...@amd.com> Reviewed-by: Rahul Singh <rahul.si...@arm.com>
I have committed the patch. Cheers, -- Julien Grall
