Hi,
While trying to conduct some regression testing, I've hit the following
build issue for ia64:
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))
Bissection report the following commit as the root cause of the broken build:
8594d83261d14754288ef00993f0971131ff08eb is the first bad commit
commit 8594d83261d14754288ef00993f0971131ff08eb

iommu/vt-d: Simplify include/linux/dmar.h
Simplify include/linux/dmar.h a bit based on the fact that
both CONFIG_INTEL_IOMMU and CONFIG_IRQ_REMAP select CONFIG_DMAR_TABLE.
