Remove /^\s*\*\n \*\s+\$FreeBSD\$$\n/
2023-06-06Switch to contigmalloc in the Hyper-V codeAndrew Turner
In the Hyper-V drivers we need to allocate buffers shared between the host and guest. This memory has been allocated with bus_dma, however it doesn't use this correctly, e.g. it is missing calls to bus_dmamap_sync. Along with this on arm64 we need this memory to be mapped with the correct memory type that bus_dma may not use. Switch to contigmalloc to allocate this memory as this will correctly allocate cacheable memory.

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

The assumption that the channel is only opened upon synthetic device attach time no longer holds, e.g. Hyper-V network device MTU changes. We have to allow device drivers to preallocate bufrings, e.g. in attach DEVMETHOD, to prevent bufring allocation failure once the system memory is fragmented after running for a while.
