316f6f2f7fa613d13316ea966a34ee5285b987ec - igbv: Isolate VF policy and validate its registers

Thu, 30 Jul 2026 06:05:47 +0200

igbv: Isolate VF policy and validate its registersGive igb virtual functions a separate ifdi method table and moveVF-specific attach, reset, queue, interrupt, and diagnostic policy toif_igbv.c. Keep shared descriptor-ring mechanisms in if_em.c.Derive VF identity from IFLIB_IS_VF and assert that hardwareidentification agrees. Under INVARIANTS, validate normal VF CSRaccesses against the sparse 82576 and I350 VF register maps.Stop shared setup from accessing PF-only controls. Require MSI-X anddefer VF sysctls until attach succeeds so failed attachment cannotleave handlers pointing at freed driver state.Advertise only VF capabilities, run adaptive moderation without thePF receive-buffer guard, enable SRRCTL.DROP_EN, and provide a VF-safediagnostic register view.The moved implementation is the existing FreeBSD code. Register modelwas cross-checked against the Intel datasheets and other Intel drivers.Sponsored by: BBOX.io List of files: /freebsd/sys/modules/em/Makefile

a2ed165f0049595f2e52ec545095240e362f27c7 - igb: Add SR-IOV PF support for 82576 and I350

Tue, 28 Jul 2026 23:56:33 +0200

igb: Add SR-IOV PF support for 82576 and I350Add the PCI IOV schema and PF control plane for up to seven VFs withone hardware queue per pool. Implement VF mailbox handling, MAC andVLAN assignment, multicast filtering, promiscuity policy,anti-spoofing, malicious-driver recovery, reset replay, and queuelifecycle management.The basic SR-IOV and VMDq PF implementation follows DPDK Intel e1000code, including PF pool selection, one queue per pool, mailboxdispatch, and VF enablement. Intel FreeBSD igb-2.5.31 supplies theolder driver baseline. Linux igb and the Intel SDMs clear up lifecycle,isolation, reset, and family-specific details absent from DPDK.Enabling IOV requires the PF to attach with one TX and RX queue.Systems whose defaults select RSS queues must set the documented iflibqueue override tunables before attach.Only 82576 and I350 support SR-IOV in silicon. The series has beenextensively tested on I350, including thowing boundaries at the PCI BARthat shipping drivers will never. Still, think carefully beforereaching for this in critical environments.Relnotes: yesSponsored by: BBOX.io List of files: /freebsd/sys/modules/em/Makefile

e6b9ce25ec062b45038a37c88d193fa438f5ef58 - igbv: Split 82576 and I350 VF registration off igb

Wed, 29 Jul 2026 02:03:08 +0200

igbv: Split 82576 and I350 VF registration off igbRegister the 82576 and I350 VF PCI IDs under a separate igbv driverwhile continuing to share the igb datapath implementation.Follow the ixv driver split and give the VF context IFLIB_IS_VF soiflib does not apply the PF SR-IOV detach guard to a child VF. ProgramVTIVAR_MISC in the VF low byte so mailbox and reset notifications reachthe VF admin vector.The split will become increasingly obvious as bug fixes land, trying tobias everything with if (sc->vf_ifp) everywhere is error prone in twodirections.This breaks existing naming/configurations and cannot be MFCed as-is.I have no plans of adapting it to prior branches at the moment but itmay be possible.Relnotes: yesSponsored by: BBOX.io List of files: /freebsd/sys/modules/em/Makefile

43d1e6ee299ad4e143d90d3ad374d1c24bd3306f - Use symlinks for kernel modules rather than hardlinks

Sat, 20 Apr 2019 14:51:05 +0200

Use symlinks for kernel modules rather than hardlinksWhen aliasing a kernel module to a different name (ie if_igb for if_em),it's better to use symlinks than hard links. kldxref will omit entries forthe links, ensuring that the loaded module has the correct name.Reviewed by: impMFC after: 2 weeksSponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D19979 List of files: /freebsd/sys/modules/em/Makefile
