* runq: More selective includes of <sys/runq.h> to reduce pollutionOlivier Certner2025-06-181-1/+0
| | | | | | | | | | | <sys/proc.h> doesn't need <sys/runq.h>. Remove this include and add it back for kernel files that relied on the pollution.

* usb: serial: allow the open/close sleep to be interruptibleKyle Evans2024-12-111-0/+1
| | | | | | | | | | | ucom_queue_command will issue commands for open/close, then wait on them to be finished. In the spirit of playing it safe, allow ucom_queue_command's wait to be interrupted in case the usb process gets jammed up waiting on the hardware -- we can at least recover the user thread that initiated it, even if we can't recover the usb process.

* 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 the realtime properties of USB transfers for embedded systemsHans Petter Selasky2015-08-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Try to resolve a possible deadlock when detaching USB devices whichHans Petter Selasky2014-03-201-0/+1
| | | | | | | | | | | | | | | | | create character devices. The deadlock can happen if an application is issuing IOCTLs which require USB refcounting, at the same time the USB device is detaching. There is already a counter in place in the USB device structure to detect this situation, but it was not always checked ahead of invoking functions that might destroy character devices, like detach, set configuration, set alternate interface or detach active kernel driver.

* Modify the FreeBSD USB kernel code so that it can be compiled directlyHans Petter Selasky2013-01-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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
