usb: xhci: add debugfs support for ep with stream

2020-09-20T14:18:00Z

To show the trb ring of streams, use the exsiting ring files of bulk ep to show trb ring of one specific stream ID, which stream ID's trb ring will be shown, is controlled by a new debugfs file stream_id, this is to avoid to create a large number of dir for every allocate stream IDs, another debugfs file stream_context_array is created to show all the allocated stream context array entries.

xhci: don't create endpoint debugfs entry before ring buffer is set.

2020-09-20T14:18:00Z

Make sure xHC completes the configure endpoint command and xhci driver sets the ring pointers correctly before we create the user readable debugfs file. In theory there was a small gap where a user could have read the debugfs file and cause a NULL pointer dereference error as ring pointer was not yet set, in practise we want this change to simplify the upcoming streams debugfs support.

xhci: Tune interrupt blocking for isochronous transfers

2020-09-20T14:18:00Z

controllers with XHCI_AVOID_BEI quirk cause too frequent interrupts and affect power management. To avoid interrupting on every isochronous interval the BEI (Block Event Interrupt) flag is set for all except the last Isoch TRB in a URB. This lead to event ring filling up in case several isoc URB were queued and cancelled rapidly, which some controllers didn't handle well, and thus the XHCI_AVOID_BEI quirk was introduced. see commit 227a4fd801c8 ("usb: xhci: apply XHCI_AVOID_BEI quirk to all Intel xHCI controllers") With the XHCI_AVOID_BEI quirk each Isoch TRB will trigger an interrupt. This can cause up to 8000 interrupts per second for isochronous transfers with HD USB3 cameras, affecting power saving. The event ring fits 256 events, instead of interrupting on every isochronous TRB if XHCI_AVOID_BEI is set we make sure at least every 8th Isochronous TRB asserts an interrupt, clearing the event ring.

usb: xhci: omit duplicate actions when suspending a runtime suspended host.

2020-09-20T14:18:00Z

If the xhci-plat.c is the platform driver, after the runtime pm is enabled, the xhci_suspend is called if nothing is connected on the port. When the system goes to suspend, it will call xhci_suspend again if USB wakeup is enabled. Since the runtime suspend wakeup setting is not always the same as system suspend wakeup setting, eg, at runtime suspend we always need wakeup if the controller is in low power mode; but at system suspend, we may not need wakeup. So, we move the judgement after changing wakeup setting.
