* sys/sys: 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=326256

* A driver for programming the AGP hardware. This is only very lightlyDoug Rabson2000-06-091-0/+128
tested on Intel BX chipsets only. The other agp minidrivers are totally untested. The programming api is a subset of the Linux api and is only intended to be enough for the X server to use. There is also an in-kernel api for the use of other kernel modules such as the 3D DRI. Notes: svn path=/head/; revision=61452
