Description John Kacur 2014-08-26 20:05:37 UTC
Enable XHCI (USB 3.0)

This will allow realtime to support more hardware, as well as bring the configuration closer to rhel6.x

Comment 1 John Kacur 2014-08-27 12:58:07 UTC
All configs changed to the following

CONFIG_USB_XHCI_HCD=m
# CONFIG_USB_XHCI_HCD_DEBUGGING is not set

Change is added to v3.10.47-rt50.49 and up

Comment 2 Arnaldo Carvalho de Melo 2014-08-27 14:12:24 UTC
Which is the default in the RHEL6 kernels, where, as in MRG, the other HCDs ([eou]hci_hcd are all built into vmlinux. Ack.

Comment 4 John Kacur 2014-11-05 14:23:10 UTC
Note, also available in 3.10.58-rt62.54
