The PPC64 kconfig is a bit of a rats nest, but it turns out that if CONFIG_SPAPR_TCE_IOMMU is on then EEH must be too: config SPAPR_TCE_IOMMU bool "sPAPR TCE IOMMU Support" depends on PPC_POWERNV || PPC_PSERIES select IOMMU_API help Enables bits of IOMMU API required by VFIO. The iommu_ops is not implemented as it is not necessary for VFIO. config PPC_POWERNV select FORCE_PCI config PPC_PSERIES select FORCE_PCI config EEH bool depends on (PPC_POWERNV || PPC_PSERIES) && PCI default y So, just open code the call to eeh_enabled() into tce_iommu_ioctl().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
