This subclass declares its own softc structure adding necessary members
after the embedded ehci_softc_t. The full size of the struct must be
included in the driver declaration, otherwise the allocation backing the
softc is not guaranteed to be large enough.

apple_bce/vhci: add T2 virtual USB host controller2026-06-14T20:56:53ZAbdelkader Boudihfreebsd@seuros.com2026-06-14T20:54:28Zurn:sha1:9f90536c74b8172fc67cd977e5451f37a12462d5
Implements a VHCI driver on top of the BCE transport:
- Virtual USB bus registration via usb_controller
- Port discovery and device enumeration
- Control, interrupt, and bulk endpoint support
- Firmware event handling with taskqueue
- Suspend/resume via BCE mailbox
Provides keyboard, trackpad, and Touch Bar access on T2 Macs.
Tested-on: MacBookPro16,2 (A2251), Mac mini 8,1 (A1993)

xhci: Do not drop and add bits in xhci2026-05-22T07:41:07ZShengYi Hungaokblast@FreeBSD.org2026-05-21T12:49:42Zurn:sha1:28d85db46b484589e2ee74cf4b270db066821de1
Drop and Add bits reset the data toggle for high-speed devices in XHCI.
The toggle bit represents the sequence number in USB 2.0 transfers. However,
a device can only recognize that the toggle bit has been reset while in
the HALT state. As a result, the host and device toggle values may
become mismatched, causing xHCI to reject the packet. This issue was
observed while testing the EZ-USB FX2 device.
The transfer may then return to the original value after a
bi-directional TD because the toggle field is only one bit wide. This
explains the reson that we can only receive packets bi-transfer in some
case. Therefore, we do not reset the toggle bit here.

chore: replace {0, 0} with {DEV,KOBJ}METHOD_END2026-02-25T05:59:34ZEnji Cooperngie@FreeBSD.org2026-02-21T06:14:46Zurn:sha1:0fc6c3f731a2cca3120798806c330a3081c9424b
Both of the aforementioned macros have been present in FreeBSD
for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for
`DEVMETHOD_END`.
Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`
and `KOBJMETHOD_END` as appropriate. This helps ensure that
future adaptations to drivers following patterns documented
in driver(9) can be made more easily/without issue.

Parse out and display xhci controller extended capabilities. This gives
us a mechanism to pick these up when the controller attaches. The print
helps users and developer know the availability of features in the wild.
This change will let developers know from dmesg that a controller
supports USB debugging.
