:Clang to replace GCC in the FreeBSD base system
Clang to replace GCC in the FreeBSD base system

"GPU device drivers are increasingly requiring more sophisticated support for mapping objects into both userland and the kernel. For example, memory used for textures often needs to be mapped Write-Combining rather than Write-Back. I have recently created three patches to provide several extensions.

"The first patch allows device drivers to use a different VM object to back specific mmap() calls instead of always using the device pager. The second patch introduces a new VM object type that can map an arbitrary set of physical address ranges. This can be used to let userland mmap PCI BARs, etc. The third patch allows memory mappings to use different caching modes (e.g. Write-Combining or Uncacheable).

"Together I believe these patches provide the remaining pieces needed for an Nvidia amd64 driver. They will also be useful for future Xorg DRM support as well. The current set of patches can be safely merged back to 7.x as well."
