iommufd: Add a selftest Cover the essential functionality of the iommufd with a directed test from userspace. This aims to achieve reasonable functional coverage using the in-kernel self test framework. A second test does a failure injection sweep of the success paths to study error 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 huge pages which may require: echo 4 > /proc/sys/vm/nr_hugepages Link: https://lore.kernel.org/r/19-v6-a196d26f289e+11787-iommufd_jgg@nvidia.com Tested-by: Nicolin Chen <nicolinc@nvidia.com> Tested-by: Matthew Rosato <mjrosato@linux.ibm.com> # s390 Tested-by: Yi Liu <yi.l.liu@intel.com> Tested-by: Eric Auger <eric.auger@redhat.com> # aarch64 Signed-off-by: Nicolin Chen <nicolinc@nvidia.com> Signed-off-by: Yi Liu <yi.l.liu@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> 2022-11-30 04:29:42 +08:00			`# SPDX-License-Identifier: GPL-2.0-only`
