AMD & FreeBSD Begin Collaborating Over OS Improvements

“Work continued on a joint project between Advanced Micro Devices (AMD) and The FreeBSD Foundation to develop a complete FreeBSD AMD IOMMU driver. This work will allow FreeBSD to fully support greater than 256 cores with features such as CPU mapping and will also include bhyve integration. Konstantin Belousov has been working on various parts of the project, including driver attachment, register definitions, an ACPI table parser, and utility functions. Two key components that need to be completed are context handling, which is mostly a generalization of Intel DMAR code, and page table creation. After this, the AMD driver’s enable bit can be turned on for testing. To follow all of Konstantin’s work, look for src commits tagged with Sponsored by fields for Advanced Micro Devices (AMD) and The FreeBSD Foundation.”
