* MFC r260588 and r260589:Hans Petter Selasky2014-01-241-2/+7
| | | | | | | | | | | | | - Separate I/O errors from reception of STALL PID. - Implement better error recovery for Transaction Translators, TTs, found in High Speed USB HUBs which translate from High Speed USB into FULL or LOW speed USB. In some rare cases SPLIT transactions might get lost, which might leave the TT in an unknown state. Whenever we detect such an error try to issue either a clear TT buffer request, or if that is not possible reset the whole TT. Notes: svn path=/stable/10/; revision=261105

* Workaround for for a problem seen with ATI Technologies EHCIHans Petter Selasky2013-05-271-0/+13
| | | | | | | | | | | | | | | | | | | controller hardware most likely present on UHCI chipsets aswell. The bug manifests itself when issuing isochronous transfers and bulk transfers towards the same device simultaneously. From time to time it happens that either the completion IRQ was missing or that the completion IRQ was happening before the ITD/SITD was completely written back to memory. The workaround assumes that double buffered isochronous transfers are used, and that a second interrupt is generated at the beginning of the next isochronous transfer to complete the previous one. Possibly skipping the interrupt at the last isochronous frame is possible, but will then break single buffered isochronous transfers. For now we can live with some extra interrupts.

* Modify the FreeBSD USB kernel code so that it can be compiled directlyHans Petter Selasky2013-01-301-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems or embedded platforms. 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. Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all USB files follow the same style. Use cases: - console in loader via USB - loading kernel via USB Discussed with: Hiroki Sato, hrs @ EuroBSDCon Notes: svn path=/head/; revision=246122
* Add missing CTLFLAG_TUN flag to tunable sysctls in USB stack.Hans Petter Selasky2012-10-261-4/+3
| | | | | | | | | | | Rearrange the tunables and belonging sysctl declarations, so that they are next to eachother. Submitted by: n_hibma @ MFC after: 1 week Notes: svn path=/head/; revision=242126
* Make several timing parameters of the USB enumeration sequence tuneable.Hans Petter Selasky2012-10-241-2/+2
| | | | | | | | | | | | | | Also update the port reset time from 250ms to 50ms. Some USB devices have a hard limit in hardware at 222ms for the port reset time and will not enumerate unless this delay is closer to the usb.org defined value. This patch can fix enumeration with some USB devices. Tested by: Guido van Rooij Submitted by: Nick Hibma MFC after: 1 week Notes: svn path=/head/; revision=241987
* Inherit USB mode from RootHUB port where the USB device is connected.Hans Petter Selasky2012-10-011-4/+0
| | | | | | | | | | Only RootHUB ports can be dual mode. Disallow OTG ports on external HUBs. This simplifies some checks in the USB controller drivers. MFC after: 1 week Notes: svn path=/head/; revision=241082

* Implement better support for USB controller suspend and resume.Hans Petter Selasky2011-12-141-27/+29
| | | | | | | | | | | | | This patch should remove the need for kldunload of USB controller drivers at suspend and kldload of USB controller drivers at resume. This patch also fixes some build issues in avr32dci.c MFC after: 2 weeks Notes: svn path=/head/; revision=228483
* Style change.Hans Petter Selasky2011-11-121-1/+1
| | | | | | | | | | | | | | | - Make it easier to port the USB code to other platforms by only using one set of memory functions for clearing and copying memory. None of the memory copies are overlapping. This means using bcopy() is not required. - Fix a compile warning when USB_HAVE_BUSDMA=0 - Add missing semicolon in avr32dci. - Update some comments.

| | | | | | | | | | | | | | | Refactor how we interface with the root HUB. This is achieved by making a direct call from usb2_do_request to the host controller for root hub requests, this call will perform the controller specific register read/writes and return the error code.
