MFC r352556: Add quirk for XHCI(4) controllers to support USB control transfers above 1Kbyte. It might look like some XHCI(4) controllers do not support when the USB control transfer is split using a link TRB. The next NORMAL TRB after the link TRB is simply failing with XHCI error code 4. The quirk ensures we allocate a 64Kbyte buffer so that the data stage TRB is not broken with a link TRB.

MFC r305421: Resolve deadlock between device_detach() and usbd_do_request_flags() by reviving the SX control request lock and refining which lock protects the common scratch area in "struct usb_device".
The SX control request lock was removed by r246759 because it caused a lock order reversal with the USB enumeration lock inside usbd_transfer_setup() as a function of r246616. It was thought that reducing the number of locks would resolve the LOR, but because some USB device drivers use usbd_do_request_flags() inside callback functions, like in taskqueues, a deadlock may occur when these are drained from device_detach(). By restoring the SX control request lock usbd_do_request_flags() is allowed to complete its execution when a USB device driver is detaching. By using the SX control request lock to protect the scratch area, the LOR introduced by r246616 is also resolved.
Bump the FreeBSD version while at it to force recompilation of all USB kernel modules.

Improve the realtime properties of USB transfers for embedded systems like RPI-B and RPI-2.
Description of problem: USB transfers can process data in their callbacks sometimes causing unacceptable latency for other USB transfers. Separate BULK completion callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give BULK completion callbacks lesser execution priority than the others. This way USB audio won't be interfered by heavy USB ethernet usage for example.
Further serve USB transfer completion in a round robin fashion, instead of only serving the most CPU hungry. This has been done by adding a third flag to USB transfer queue structure which keeps track of looping callbacks. The "command" callback function then decides what to do when looping.

Ensure that the DMA delay does not get rounded down to zero ticks when a timeout value of a single tick is given. With FreeBSD-10 and newer the current system time is used as a starting point, and the minimum callout time of a single tick will be guaranteed.

This is also useful for out of the system compilation of the FreeBSD USB stack for various purposes. The USB kernel files can now optionally include a global header file which should include all needed definitions required to compile the FreeBSD USB stack. When the global USB header file is included, no other USB header files will be included by default.
Add new file containing the USB stack configuration for the FreeBSD loader build.

Add support for the so-called streams feature of BULK endpoints in SUPER-speed mode, USB 3.0.
This feature has not been tested yet, due to lack of hardware.
This feature is useful when implementing protocols like UASP, USB attached SCSI which promises higher USB mass storage throughput.
This patch also implements support for hardware processing of endpoints for increased performance. The switching to hardware processing of an endpoint is done via a callback to the USB controller driver. The stream feature is implemented like a variant of a hardware USB protocol.
USB controller drivers implementing device mode needs to be updated to implement the new "xfer_stall" USB controller method and remove the "xfer" argument from the "set_stall" method.
The API's toward existing USB drivers are preserved. To setup a USB transfer in stream mode, set the "stream_id" field of the USB config structure to the desired value.
The maximum number of BULK streams is currently hardcoded and limited to 8 via a define in usb_freebsd.h.
All USB drivers should be re-compiled after this change.
LibUSB will be updated next week to support streams mode. A new IOCTL to setup BULK streams as already been implemented. The ugen device nodes currently only supports stream ID zero.
The FreeBSD version has been bumped.

Avoid to check the same cache line/variable from all the locking primitives by breaking stop_scheduler into a per-thread variable. Also, store the new td_stopsched very close to td_*locks members as they will be accessed mostly in the same codepaths as td_stopsched and this results in avoiding a further cache-line pollution, possibly.
STOP_SCHEDULER() was pondered to use a new 'thread' argument, in order to take advantage of already cached curthread, but in the end there should not really be a performance benefit, while introducing a KPI breakage.

adapt usb transfer code for SCHEDULER_STOPPED
When SCHEDULER_STOPPED() is true the mtx_owned() call may return an unexpected and thus meaningless result. So, in the code paths that can be reached when SCHEDULER_STOPPED() is true we need to protect the mtx_owned() calls with the SCHEDULER_STOPPED() checks and ensure that an appropriate branch is taken in each case.

This commit adds full support for USB 3.0 devices in host and device mode in the USB core. The patch mostly consists of updating the USB HUB code to support USB 3.0 HUBs. This patch also add some more USB controller methods to support more active-alike USB controllers like the XHCI which needs to be informed about various device state events.
USB 3.0 HUBs are not tested yet, due to lack of hardware, but are believed to work.
After this update the initial device descriptor is only read twice when we know that the bMaxPacketSize is too small for a single packet transfer of this descriptor.

- clean up USB detach logic. There seems to be some problems detaching multiple USB HUBs connected in series from the root.
- after this patch the rule is: 1) Always use device_detach() on the USB HUB first. 2) Never just device_delete_child() on the USB HUB, because that function will traverse to all the device leaves and free them first, and then the USB stack will free the devices twice which doesn't work very well.
- make sure the did DMA delay gets set after the timeout has elapsed to make logic more clear. There is no functional difference.

To compensate for this "usb2_config" has a new field called "usb_mode" which select for which mode the current xfer entry is active. Options are: a) Device mode only b) Host mode only (default-by-zero) c) Both modes. This change was scripted using the following sed script: "s/\.mh\././g". - the standard packet size table in "usb_transfer.c" is now a function, hence the code for the function uses less memory than the table itself.

Reduce the number of callback processes to 4 per USB controller. There are two rough categories: 1) Giant locked USB transfers. 2) Non-Giant locked USB transfers. On a real system with many USB devices plugged in the number of processes reported by "ps auxw | grep USBPROC" was reduced from 40 to 18.

This change is about removing three fields from "struct usb2_xfer" which can be reached from "struct usb2_xfer_root" instead and cleaning up the code after this change. The fields are "xfer->udev", "xfer->xfer_mtx" and "xfer->usb2_sc". In this process the following changes were also made: Rename "usb2_root" to "xroot" which is short for "xfer root". Rename "priv_mtx" to "xfer_mtx" in USB core. The USB_XFER_LOCK and USB_XFER_UNLOCK macros should only be used in the USB core due to dependency towards "xroot". Substitute macros for the real lock in two USB device drivers.

Bring in USB4BSD, Hans Petter Selasky rework of the USB stack that includes significant features and SMP safety.
This commit includes a more or less complete rewrite of the *BSD USB stack, including Host Controller and Device Controller drivers and updating all existing USB drivers to use the new USB API:
1) A brief feature list:
- A new and mutex enabled USB API.
- Many USB drivers are now running Giant free.
- Linux USB kernel compatibility layer.
- New UGEN backend and libusb library, finally solves the "driver unloading" problem. The new BSD licensed libusb20 library is fully compatible with libusb-0.1.12 from sourceforge.
- New "usbconfig" utility, for easy configuration of USB.
- Full support for Split transactions, which means you can use your full speed USB audio device on a high speed USB HUB.
- Full support for HS ISOC transactions, which makes writing drivers for various HS webcams possible, for example.
- Full support for USB on embedded platforms, mostly cache flushing and buffer invalidating stuff.
- Safer parsing of USB descriptors.
- Autodetect of annoying USB install disks.
- Support for USB device side mode, also called USB gadget mode, using the same API like the USB host side. In other words the new USB stack is symmetric with regard to host and device side.
- Support for USB transfers like I/O vectors, means more throughput and less interrupts.
- ... see the FreeBSD quarterly status reports under "USB project"
2) To enable the driver in the default kernel build:
2.a) Remove all existing USB device options from your kernel config file.
2.b) Add the following USB device options to your kernel configuration file:
# USB core support device usb2_core
# USB controller support device usb2_controller device usb2_controller_ehci device usb2_controller_ohci device usb2_controller_uhci
# USB mass storage support device usb2_storage device usb2_storage_mass
# USB ethernet support, requires miibus device usb2_ethernet device usb2_ethernet_aue device usb2_ethernet_axe device usb2_ethernet_cdce device usb2_ethernet_cue device usb2_ethernet_kue device usb2_ethernet_rue device usb2_ethernet_dav
# USB wireless LAN support device usb2_wlan device usb2_wlan_rum device usb2_wlan_ral device usb2_wlan_zyd
# USB serial device support device usb2_serial device usb2_serial_ark device usb2_serial_bsa device usb2_serial_bser device usb2_serial_chcom device usb2_serial_cycom device usb2_serial_foma device usb2_serial_ftdi device usb2_serial_gensa device usb2_serial_ipaq device usb2_serial_lpt device usb2_serial_mct device usb2_serial_modem device usb2_serial_moscom device usb2_serial_plcom device usb2_serial_visor device usb2_serial_vscom
# USB bluetooth support device usb2_bluetooth device usb2_bluetooth_ng
# USB input device support device usb2_input device usb2_input_hid device usb2_input_kbd device usb2_input_ms
# USB sound and MIDI device support device usb2_sound
2) To enable the driver at runtime:
2.a) Unload all existing USB modules. If USB is compiled into the kernel then you might have to build a new kernel.
2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same base name like the kernel device option.
