Hi Denis,
I found a couple issues with your second patch. There are non-PCI xHCI
host controllers, so we can't assume the xHCI host is a PCI host. So
this code can't run in the generic xHCI shutdown method:
> void xhci_shutdown(struct usb_hcd *hcd)
> {
> + struct pci_dev *pdev;
> + const char *brd_name;
> struct xhci_hcd *xhci = hcd_to_xhci(hcd);
>
> + pdev = to_pci_dev(hcd->self.controller);
> +
> + if (usb_is_intel_switchable_xhci(pdev)) {
> + brd_name = dmi_get_system_info(DMI_BOARD_NAME);
> +
> + /* quirk for Compulab's Intense-PC board */
> + if (brd_name && strstr(brd_name, "Intense-PC"))
> + usb_disable_xhci_ports(pdev);
> + }
> +
> spin_lock_irq(&xhci->lock);
> xhci_halt(xhci);
> spin_unlock_irq(&xhci->lock);
I think the to_pci_dev call will oops if this isn't a PCI host. Plus,
I've found out from the BIOS and chipset folks that this quirk needs to
be more broadly applied. I'll send you a revised patch. Can you test
it and make sure it works for you?
