iommufd: Add config needed for iommufd_fail_nthAdd FAULT_INJECTION_DEBUG_FS and FAILSLAB configurations to the kconfigfragment for the iommfd selftests. These kconfigs are needed by theiommufd_fail_nth test.Fixes: a9af47e382a4 ("iommufd/selftest: Test IOMMU_HWPT_GET_DIRTY_BITMAP")Link: https://lore.kernel.org/r/20240325090048.1423908-1-usama.anjum@collabora.comSigned-off-by: Muhammad Usama Anjum Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/tools/testing/selftests/iommu/config

iommufd: Add a selftestCover the essential functionality of the iommufd with a directed test fromuserspace. This aims to achieve reasonable functional coverage using thein-kernel self test framework.A second test does a failure injection sweep of the success paths to studyerror unwind behaviors.This allows achieving high coverage of the corner cases in pages.c.The selftest requires CONFIG_IOMMUFD_TEST to be enabled, and several hugepages which may require: echo 4 > /proc/sys/vm/nr_hugepagesLink: https://lore.kernel.org/r/19-v6-a196d26f289e+11787-iommufd_jgg@nvidia.comTested-by: Nicolin Chen Tested-by: Matthew Rosato # s390Tested-by: Yi Liu Tested-by: Eric Auger # aarch64Signed-off-by: Nicolin Chen Signed-off-by: Yi Liu Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/tools/testing/selftests/iommu/config
