* MFC r283922:hselasky2015-06-051-56/+52
| | | | | | | Fix for control endpoint handling in the DWC OTG driver. The data stage processing is only allowed after the setup complete event has been received. Else a race may occur and the OUT data can be corrupted. While at it ensure resetting a FIFO has the required wait loop.
* MFC r283103:hselasky2015-06-031-2/+31
| | | | | Fix for DWC OTG device side isochronous transfers. The even or odd isochronous frame bit needs to be flipped.
* MFC r281881:hselasky2015-05-051-9/+7
| | | | | | Disable multi process interrupts, because the current code doesn't use them. Else we can end up in an infinite interrupt loop in USB device mode.
* MFC r279563:hselasky2015-03-061-1/+12
| | | | Add quirk for USB 3.0 controllers which don't support 64-bit DMA.
* MFC r279544:hselasky2015-03-053-6/+12
| | | | | | Add quirk to disable 64-bit XHCI DMA after r276717. Requested by: Gary Jennejohn <gljennjohn@gmail.com>
* MFC r279210:hselasky2015-03-052-12/+49
| | | | | | Add support for the DWC OTG v2 chipset found in the STM32F4 series of processors. Make sure we pullup the data lines in device mode when we power on the port.
* MFC r279233:hselasky2015-02-271-0/+7
| | | | | | Ensure that the XHCI driver will refresh the control endpoint settings when re-enumerating a FULL speed device. Else the wrong max packet setting might be used when trying to re-enumerate a FULL speed device.

Revise the arm bus_space implementation to avoid dereferencing the tag on every operation to retrieve the bs_cookie value almost nothing actually uses. Use the explicit member initializer style to init the bus_space struct. Use arm/bus_space-v6.c for all armv6 systems Consolidate many identical implementations of bus_space to a single common tag and implementation shared by armv4 and armv6. Micro-optimize the new arm inline bus_space implementation by grouping all the data the inline functions access together at the start of the bus_space struct so that they all fit in a single cache line.

* MFC r278071:hselasky2015-02-101-1/+11
| | | | | | | Section 3.2.9 in the XHCI specification about control transfers says that we should use a normal-TRB if there are more TRBs extending the data-stage TRB. Add a dedicated state bit to the internal USB transfer flags to handle this case.
* MFC r277136:hselasky2015-02-051-0/+40
| | | | | | | | | | Resolve a special case deadlock: When two or more threads are simultaneously detaching kernel drivers on the same USB device we can get stuck in the "usb_wait_pending_ref_locked()" function because the conditions needed for allowing detach are not met. While at it ensure that "flag_iserror" is only written when "priv_mtx" is locked, which is protecting it.
* MFC r266969 and r276717:hselasky2015-02-0520-56/+82

* MFC r276321, r276404, r276407 and r276799:hselasky2015-01-113-29/+48
| | | | | | | | | | | | Various XHCI fixes and improvements: - Improve and fix MSI interrupt allocation, setup and release. - Add missed flushing of data which can happen when "xhci_configure_mask()" is called from "xhci_configure_reset_endpoint()". Ensure the 3-strikes error feature is always enabled except for ISOCHRONOUS transfers. - Allow systems having a page size greater than 4K to use fewer scatter-gather XHCI TRB entries for its payload data. The XHCI controller can handle at least 65536 bytes per scatter-gather list entry.

* MFC r272349, r272422 and r272479:hselasky2014-10-062-8/+16
| | | | | | | | | | - Fix XHCI driver for devices which have more than 15 physical root HUB ports. The current bitmap array was too small to hold more than 16 bits and would at some point toggle the context size, which then would trigger an enumeration fault and cause a fallback to the EHCI companion controller, if any. - Make sure we always set the maximum number of valid contexts. - Set default cycle state in case of early interrupts.
* MFC r271953:hselasky2014-09-251-1/+8

* MFC r267240:hselasky2014-06-111-1/+7
| | | | | | | | | Resolve a deadlock setting the USB configuration index from userspace on USB HUBs by moving the code into the USB explore threads. The deadlock happens because child devices of the USB HUB don't have the expected reference count when called from outside the explore thread. Only the HUB device itself, which the IOCTL interface locks, gets the correct reference count.

| | | | | | | | | | | | | Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result. Similar to the (1 << 31) case it is not defined to do (2 << 30). This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD.
