Mon, 07 Sep 2026 05:34:50 +0200

ixv: Add Hyper-V virtual function supportHyper-V does not expose the normal Intel PF/VF mailbox.Import the Hyper-V operation overrides from DPDK and complete its resetcallback with the configuration-space mechanism submitted by Microsoft.Route ixv operations through the operation table, use mailbox API 1.0,and limit this environment to one queue pair.Claim the 82599, X540, X550, X550EM-X, and X550EM-A Hyper-V device IDslisted by DPDK. Select the same path for the E610 Hyper-V subdeviceidentity defined there.For E610/Linkville, read the emulated VFLINKS-format status from PCIconfiguration space at offset 0x209. Older families retain the MMIOVFLINKS path.Treat receive-mode changes as host-owned no-ops and do not retry VLANoperations that Hyper-V permanently rejects. Limit the Hyper-V 82599MTU to 1504 because its VF does not implement the X540 RLPML field.Use mailbox reset indications only to refresh cached Hyper-V link state.Hyper-V does not provide the mailbox handshake required to treat thatindication as a request for an iflib reinitialization.Tested on 82599 and E610 (with a followup commit) with Windows Server2025 Hyper-V.PR: 232472, 239849Obtained from: DPDK (shared code)Sponsored by: BBOX.ioCo-authored-by: Wei Hu List of files: /freebsd/sys/conf/files

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.

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/conf/files

Sat, 18 Jul 2026 13:54:42 +0200

LinuxKPI: page pool updates and add to the buildSplit implementation out from the header files.This "page pool" is the very minimalistic version we need in order tosupport packets on mt76.We allocate the page pool in order to have the meta data available ofwhich we only make limited use.This implementation does no pooling, it does no page fragments for now,it always hands out a full page and frees it upon return.It is written in a way that it can be in the tree before the 'struct page'work it depends on has landed in order to reduce friction for people whowant to try mt7921 (or others later) upfront. We use the same #ifdefas in the struct page work for that reason so one knob will turn everythingon or off.Once the struct page work has landed and settled we can start filling thiswith more complexity.In the unlikely event that in the mean time any other consumer would startshowing up they will have to be aware that the current code as-isessentially is a NOP without the 'struct page' work. A WARN_ONCE() willnotify them.Sponsored by: The FreeBSD FoundationMFC after: 3 days List of files: /freebsd/sys/conf/files

dc5c0fc51cf47d6dfc737343e06805db294258e9 - aq(4): add Atlantic 2 (AQC113) device support

Sun, 19 Jul 2026 18:48:05 +0200

aq(4): add Atlantic 2 (AQC113) device supportAdd support for the Marvell Atlantic 2 (AQC113/114/115/116) controllers,a new chip generation that is not register-compatible with the Atlantic 1parts aq(4) supports today. Adapted from the OpenBSD/NetBSD if_aq driver.Register and device definitions (aq2_hw.h): the firmware handshake(MIF_BOOT / MCP_HOST_REQ_INT / MIF_HOST_FINISHED), the 0x12000/0x13000firmware interface windows, and the action-resolver table (ART) thatreplaces Atlantic 1's discrete RX filters, plus the Atlantic 2 PCI deviceids and the aq_is_atlantic2() helper. Reserve a chip-feature bit(AQ_HW_CHIP_ATLANTIC2) and add the aq_hw fields the firmware fills at boot(ART base index, statistics interface version A0/B0). The per-VLAN-filterresolver-tag field comes from the Linux driver; the BSD sources neverwrite it.Firmware operations (aq_fwa2.c): Atlantic 2 talks to the management CPUthrough the 0x12000/0x13000 register windows plus the boot handshake,rather than Atlantic 1's mailbox in shared RAM. Implement that as a thirdaq_firmware_ops vtable (reset, set_mode, get_mode, get_mac_addr,get_stats); aq_fwa2_reboot() boots the firmware, selects the A2 ops, andreads the version and ART base index, failing fast on thecrash-init / boot-failed bits. fwa2_set_mode advertises full duplex only(the media model exposes no half-duplex types) and writes and acks thelink options before raising ACTIVE mode, so a forced media change does notbegin negotiation with a stale rate mask. enum aq_fw_link_speed gainsaq_fw_10M, which Atlantic 2 supports and Atlantic 1 does not.Probe and attach: list the device ids with their media types and linkspeeds (all copper; AQC113* up to 10G, AQC116C to 1G), populatehw->device_id, and tag the generation with AQ_HW_CHIP_ATLANTIC2 soIS_CHIP_FEATURE() recognises it uniformly. Branch firmware bring-up andreset on the generation: aq_hw_init_ucp() and aq_hw_reset() reboot the MCPinstead of the Atlantic 1 RBL/FLB reset -- without a real datapath resetevery stop/init cycle reprograms the rings on a live, desynced RX DMAengine and the receive path stays dead. aq_hw_init() programs theAtlantic 2 launch-time clock ratio in place of the Atlantic 1MRRS / TX-DMA request-limit clamp. Add an AQ_LINK_10M capability bit(Atlantic 2 links at 10M, Atlantic 1 cannot), offer 10baseT media, and mapIFM_10_T to aq_fw_10M.With every supported media type now present, replace the per-speed switchstatements in aq_media.c with a single {link bit, fw rate, IFM_* subtype,Mbit/s} table -- one source of truth for the supported link speeds.With this an Atlantic 2 card probes, brings up its firmware, reads itsMAC, and negotiates link; the RX action-resolver datapath comes next.Reviewed by: adrianDifferential Revision: https://reviews.freebsd.org/D58141 List of files: /freebsd/sys/conf/files
