2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
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

2002-10-23- New-bussify the rc(4) device driver.John Baldwin
- Add detach support to the driver so that you can kldunload the module. Note that currently rc_detach() fails to detach a unit if any of its child devices are open, thus a kldunload will fail if any of the tty devices are currently open. - sys/i386/isa/ic/cd180.h was moved to sys/dev/ic/cd180.h as part of this change.

2002-05-20Bump the rc driver a little bit closer to the 21st century: useRobert Watson
make_dev() to create device nodes for each of the serial port channels (ttym%d and cuam%d respectively, as borrowed from MAKEDEV). This allows the rc driver to work in 5.0. I've tested it with only one card, but will try sticking in a second card tomorrow and see what happens. Notes: svn path=/head/; revision=96969
2002-04-01Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin
general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag. Discussed on: smp@ Notes: svn path=/head/; revision=93593

2002-03-20Remove __P.Alfred Perlstein
Notes: svn path=/head/; revision=92765
2002-01-05Change the preemption code for software interrupt thread schedules andJohn Baldwin
mutex releases to not require flags for the cases when preemption is not allowed: The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent switching to a higher priority thread on mutex releease and swi schedule, respectively when that switch is not safe. Now that the critical section API maintains a per-thread nesting count, the kernel can easily check whether or not it should switch without relying on flags from the programmer. This fixes a few bugs in that all current callers of swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from fast interrupt handlers and the swi_sched of softclock needed this flag. Note that to ensure that swi_sched()'s in clock and fast interrupt handlers do not switch, these handlers have to be explicitly wrapped in critical_enter/exit pairs. Presently, just wrapping the handlers is sufficient, but in the future with the fully preemptive kernel, the interrupt must be EOI'd before critical_exit() is called. (critical_exit() can switch due to a deferred preemption in a fully preemptive kernel.) I've tested the changes to the interrupt code on i386 and alpha. I have not tested ia64, but the interrupt code is almost identical to the alpha code, so I expect it will work fine. PowerPC and ARM do not yet have interrupt code in the tree so they shouldn't be broken. Sparc64 is broken, but that's been ok'd by jake and tmm who will be fixing the interrupt code for sparc64 shortly. Reviewed by: peter Tested on: i386, alpha Notes: svn path=/head/; revision=88900

Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john! (your next MFC will be a doosie!)
