2019-12-04usb, kcov: collect coverage from hub_eventAndrey Konovalov1-0/+5
Add kcov_remote_start()/kcov_remote_stop() annotations to the hub_event() function, which is responsible for processing events on USB buses, in particular events that happen during USB device enumeration. Since hub_event() is run in a global background kernel thread (see Documentation/dev-tools/kcov.rst for details), each USB bus gets a unique global handle from the USB subsystem kcov handle range. As the result kcov can now be used to collect coverage from events that happen on a particular USB bus.

In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers.

Intel Ice Lake has two xHCI controllers one on PCH and the other as part of the CPU itself. The latter is also part of the so called Type C Subsystem (TCSS) sharing ACPI power resources with the PCIe root ports and the Thunderbolt controllers. In order to put the whole TCSS block into D3cold the xHCI needs to be runtime suspended as well when idle. For this reason allow runtime PM as default for Ice Lake TCSS xHCI controller.

2019-11-16usb: host: xhci: Support running urb giveback in tasklet contextSuwan Kim2-3/+2
Patch "USB: HCD: support giveback of URB in tasklet context"[1] introduced giveback of urb in tasklet context. [1] This patch was applied to ehci but not xhci. [2] This patch significantly reduces the hard irq time of xhci. Especially for uvc driver, the hard irq including the uvc completion function runs quite long but applying this patch reduces the hard irq time of xhci. I have tested four SS devices to check if performance degradation occurs when urb completion functions run in the tasklet context. As a result of the test, all devices works well and shows very similar performance with the upstream kernel. Moreover, usb ethernet adapter show better performance than the upstream kernel about 5% for RX and 2% for TX. Four SS devices is as follows. SS devices for test 1. WD My Passport 2TB (external hard drive) 2. Sandisk Ultra Flair USB 3.0 32GB 3. Logitech Brio webcam 4. Iptime 1gigabit ethernet adapter (Mediatek RTL8153) Test description 1.

2019-11-16usb: host: xhci: update event ring dequeue pointer on purposePeter Chen1-17/+43
On some situations, the software handles TRB events slower than adding TRBs, then xhci_handle_event can't return zero long time, the xHC will consider the event ring is full, and trigger "Event Ring Full" error, but in fact, the software has already finished lots of events, just no chance to update ERDP (event ring dequeue pointer). In this commit, we force update ERDP if half of TRBS_PER_SEGMENT events have handled to avoid "Event Ring Full" error.
