Keep the current SR-IOV points and VF selector in an iovchild namespace.Compile the facility only with options DRIVER_FAILPOINTS. This sharedoption avoids a separate kernel option for every driver that providestest-only injection hooks. Ordinary kernels contain no ICE failpointobjects or sysctl nodes. Require an exact PF device name andoptionally a VF index before any point can fire. This prevents a staletest setting from affecting another PF.The hooks exposed two reset-lifetime defects while validating theexisting SR-IOV review series. A PF reset could discard a firmware VSIbefore teardown, and a rebuilt sibling could leave stale switch-filterstate after IOV destroy.Tested on an E810-XXV with INVARIANTS and WITNESS. All twelve creationcheckpoints rolled back and permitted immediate resource reuse. Forcedreconstruction and malformed GET_STATS failures also preserved siblingoperation and reply cardinality.Reviewed by: gallatin, nprice, ziaeeMFC after: 2 weeksSponsored by: BBOX.ioDifferential Revision: https://reviews.freebsd.org/D58940 List of files: /freebsd/sys/dev/ice/ice_fault.h Wed, 19 Aug 2026 02:33:33 +0200 Kevin Bowling <kbowling@FreeBSD.org>
