About a month ago Jack Madden’s Friday EUC news-blast (worth signing-up for), highlighted a recent announcement from AMD around open-sourcing their GPU drivers for hardware shared-GPU (MxGPU) on the open-source KVM hypervisor.
The actual announcement was made by Michael De Neffe on the AMD site, here.
KVM is an open source hypervisor, favoured by many in the Linux ecosystem and segments such as education. Some commercial hypervisors are built upon KVM adding certain features and commercial support such as Red Hat RHEL. Many large users including cloud giants such as Google, take the open source KVM and roll their own version.
