Yann Droneaud <[email protected]> reported one build failure as below, which should be caused by incorrect Kconfig. CC arch/ia64/kernel/pci-dma.o ../arch/ia64/kernel/pci-dma.c: In function 'pci_iommu_init': ../arch/ia64/kernel/pci-dma.c:41:3: error: implicit declaration of function 'intel_iommu_init' [-Werror=implicit-function-declaration] intel_iommu_init(); ^ ../arch/ia64/kernel/pci-dma.c: In function 'pci_iommu_alloc': ../arch/ia64/kernel/pci-dma.c:103:2: error: implicit declaration of function 'detect_intel_iommu' [-Werror=implicit-function-declaration] detect_intel_iommu(); ^
It should be noted Kconfig complain with the following: warning: (IA64) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME) warning: (IA64_DIG_VTD) selects INTEL_IOMMU which has unmet direct dependencies (IOMMU_SUPPORT && PCI_MSI && ACPI && (X86 || IA64_GENERIC)) warning: (IA64) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME) warning: (IA64_DIG_VTD) selects INTEL_IOMMU which has unmet direct dependencies (IOMMU_SUPPORT && PCI_MSI && ACPI && (X86 || IA64_GENERIC)) Signed-off-by: Jiang Liu <[email protected]> --- Hi Yann, Could you please help to test whether this patch fix the build failure and the Kconfig warnings?
