udbc: Add usb debug host mode driver

2025-09-15T14:44:05Z

xhci offers a debugging interface which uses a special usb 3 cable with the D+, D- and VBUS pairs disconnected. This interface allows a target device to configure its xhci controller as a debugging channel which can then be used to provide a serial link between the target and a debug host. This change extracts the udbc host mode driver from hrs@'s xhci debug implementation.

umb: Introduce the USB umb(4) network driver

2025-01-20T23:46:15Z

This includes the port of a driver originally from OpenBSD, later ported to NetBSD by the author: * The umb(4) kernel driver * The umbctl(8) companion tool This driver supports USB network devices implementing the Mobile Broadband Interface Model (MBIM), often found in modern (internal) USB models for 4G/LTE mobile broadband access. It is currently limited to IPv4. umbctl has to be used to display or set MBIM cellular modem interface parameters (4G/LTE).

bcm2838_xhci: Need to generate ofw_bus_if.h

Add ofw_bus_if.h to SRCS so that this will always be generated so this can build standalone, or when FDT isn't in the kernel. Fixes: ac83063d37e5e92ad048cc4ed958654c02103f74 (for LINT-ACPI) Sponsored by: Netflix

bcm2838_xhci: add module

2024-04-10T03:11:39Z

bcm2838_xhci(4) is a shim for the XHCI controller on the Raspberry Pi 4B SoC. It loads the controller's firmware before passing control to the normal xhci(4) driver. When xhci(4) is built as a module (and not in the kernel), bcm2838_xhci is not built at all and the RPi4's XHCI controller won't attach due to missing firmware. To fix this, build a new module, bcm2838_xhci.ko, which depends on xhci.ko. For the dependency to work correctly, also modify xhci to provide the 'xhci' module in addition to the 'xhci_pci' module it already provided. Since bcm2838_xhci is specific to a quirk of the RPi4 SoC, only build the module for AArch64. Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/1142
