* spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSDWarner Losh2023-05-121-1/+1
| | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix
* 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
* Improve USB polling mode by not locking any mutexes, asserting anyHans Petter Selasky2016-09-141-0/+14
| | | | | | | | | | | | | | | | | | | | | mutexes or using any callouts when active. Trying to lock a mutex when KDB is active or the scheduler is stopped can result in infinite wait loops. The same goes for calling callout related functions which in turn lock mutexes. If the USB controller at which a USB keyboard is connected is idle when KDB is entered, polling the USB keyboard via USB will always succeed. Else polling may fail depending on which state the USB subsystem and USB interrupt handler is in. This is unavoidable unless KDB can wait for USB interrupt threads to complete before stalling the CPU(s).

* Modify the FreeBSD USB kernel code so that it can be compiled directlyHans Petter Selasky2013-01-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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
