Texas Instruments XHCI

[Dwight Schauer]

I'm with Texas Instruments and I'm trying to get our USB3 host 
controller working with FreeBSD 8.2-BETA1

This is the NEC controller wiuth xhci.ko:

xhci0: <XHCI (generic) USB 3.0 controller> mem 0xffa00000-0xffa01fff irq 
16 at device 0.0 on pci1
xhci0: [ITHREAD]
usbus5 on xhci0
usbus5: 4.8Gbps Super Speed USB v3.0

This is the TI controller:

xhci1: <XHCI (generic) USB 3.0 controller> mem 
0xff600000-0xff60ffff,0xff610000-0xff611fff irq 16 at device 0.0 on pci5
xhci1: [ITHREAD]
ugen5.1: <0x1033> at usbus5
uhub5: <0x1033 XHCI root HUB, class 9/0, rev 3.00/1.00, addr 1> on usbus5
xhci1: Driver does not support 64-byte contexts.xhci1: XHCI 
halt/start/probe failed err=18
device_attach: xhci1 attach returned 6
uhub5: 4 ports with 4 removable, self powered

I can attach a mass storage device to the NEC USB3 host controller and 
it enumerates:

ugen5.2: <Texas Instruments> at usbus5
umass0: <Texas Instruments TUSB9260 Firmware v1, class 0/0, rev 
2.10/1.00, addr 1> on usbus5
umass0:  SCSI over Bulk-Only; quirks = 0x0000
umass0:0:0:-1: Attached to scbus0
da0 at umass-sim0 bus 0 scbus0 target 0 lun 0
da0: <ATA TOSHIBA MK1655GS 1J> Fixed Direct Access SCSI-6 device
da0: 40.000MB/s transfers
da0: 152627MB (312581808 512 byte sectors: 255H 63S/T 19457C)

However, nothing happens when I attach a mass storage device to the 
Texas Instruments USB3 host controller.

Any advice is welcome.

Our host controller has been supported by the generic xhci_hcd driver in 
Linux for a while now, and we need FreeBSD support for our host 
controller as well.

If need be I can send a Texas Instruments USB3 host controller 
evaluation module to whoever is working on FreeBSD XHCI to help out in 
this effort.
