* Fix undefined behaviour in the USB controllersAndrew Turner2022-01-121-2/+1
| | | | | | | | | | | | | | | | The USB controller drivers assume they can cast a NULL pointer to a struct and find the address of a member. KUBSan complains about this so replace with the __offsetof and __containerof macros that use either a builtin function where available, or the same NULL pointer on older compilers without the builtin.

* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (2 of many)Pawel Biernacki2020-02-151-1/+1
| | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* 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 support for the so-called streams feature of BULK endpointsHans Petter Selasky2012-08-121-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. MFC after: 2 weeks Notes: svn path=/head/; revision=239214

| | | | | | | | | | | | | | | 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.
