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> | 3 年前 | |
selftests: iommu: Use installed kernel headers search path Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather than using kernel headers in include/uapi from the source kernel tree kernel headers. Remove bogus ../../../../include/ from the search path, because kernel source headers are not needed by those user-space selftests, and it causes issues because -I paths are searched before -isystem paths, and conflicts for files appearing both in kernel sources and in uapi headers with incompatible semantics (e.g. types.h).

iommufd: Add config needed for iommufd_fail_nth [ Upstream commit 2760c51b8040d7cffedc337939e7475a17cc4b19 ] Add FAULT_INJECTION_DEBUG_FS and FAILSLAB configurations to the kconfig fragment for the iommfd selftests. These kconfigs are needed by the iommufd_fail_nth test.

iommufd/selftest: Add coverage for IOMMU_HWPT_ALLOC with nested HWPTs mainline inclusion from mainline-v6.7-rc1 category: performance The IOMMU_HWPT_ALLOC ioctl now supports passing user_data to allocate a user-managed domain for nested HWPTs. Add its coverage for that. Also, update _test_cmd_hwpt_alloc() and add test_cmd/err_hwpt_alloc_nested().
