Hi folks,
What is the current state of affairs? Sooner or later we'll need a
solution for the pci-bar-access-from-real-mode issue ...
I looked briefly at the usb3 specs and I think it is impossible to drive
a xHCI adapter without access to the PCI bar.
Also AHCI support needs access to the PCI bar to submit commands and
check status.
cheers,
Gerd
