void xhci_debug_ring	(	struct xhci_hcd *	xhci,

Debugging for an xHCI ring, which is a queue broken into multiple segments.

Print out each segment in the ring. Check that the DMA address in each link segment actually matches the segment's stored DMA address. Check that the link end bit is only set at the end of the ring. Check that the dequeue and enqueue pointers point to real data in this ring (not some other ring).

Definition at line 354 of file xhci-dbg.c.

void xhci_debug_segment	(	struct xhci_hcd *	xhci,
		struct xhci_segment *	seg
	)

Debug a segment with an xHCI ring.

Returns: The Link TRB of the segment, or NULL if there is no Link TRB (which is a bug, since all segments must have a Link TRB).

Prints out all TRBs in the segment, even those after the Link TRB.

XXX: should we print out TRBs that the HC owns? As long as we don't write, that should be fine... We shouldn't expect that the memory pointed to by the TRB is valid at all. Do we care about ones the HC owns? Probably, for HC debugging.

unsigned int xhci_get_endpoint_index ( struct usb_endpoint_descriptor * desc )

xhci_get_endpoint_index - Used for passing endpoint bitmasks between the core and HCDs. Find the index for an endpoint given its descriptor. Use the return value to right shift 1 for the bitmask.

Index = (epnum * 2) + direction - 1, where direction = 0 for OUT, 1 for IN. For control endpoints, the IN index is used (OUT index is unused), so index = (epnum * 2) + direction - 1 = (epnum * 2) + 1 - 1 = (epnum * 2)
