We are currently preparing our =93enlightened=94 device drivers for inclusi= on with the standard distribution of FreeBSD. They provide significant performance enhancements to FreeBSD on Hyper-V. As part of this process we are making our source code available for review by the FreeBSD community. We would truly appreciate your comments and concerns. There are two options for enabling the drivers. You can include them as a monolithic build ( https://github.com/FreeBSDonHyper-V/freebsd/wiki/Build-the-kernel-with-the-= HyperV-drivers) or as loadable drivers by manually configuring them to load at boot time. So, while we plan to include them in the GENERIC build for AMD64, they are only loaded by including them in the boot configuration. Since we will be actively maintaining our drivers, we are placing them in a vendor branch. However, there=92s a small patch to the ATA driver that when it detects the presence of Hyper-V it disables it. This allows our =93enlightened=94 storage driver to replace it and provide Fast IDE for the file system. Furthermore, we wish that the current maintainer of the ATA driver also maintain this patch. This will allow our focus to be on our drivers and prevent us being a hindrance to any future changes to the ATA driver. Our source code can be reviewed on Github at https://github.com/FreeBSDonHyper-V/VendorBranchForFreeBSDonHyper-V. You may leave comments or questions on this issue board https://github.com/FreeBSDonHyper-V/VendorBranchForFreeBSDonHyper-V/issues. Or if you prefer, you may post them on this mailing list ( http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization).
