KVM Drops Support For IA64 While Adding Various x86 Improvements

Written by Michael Larabel in Linux Kernel on 19 December 2014 at 09:30 AM EST. 6 Comments
The KVM changes have been queued up and called for pulling into the Linux 3.19 kernel.

With the Kernel-based Virtual Machine in Linux 3.19, the code for the IA64 architecture has been dropped. Hardware-assisted virtualization for the PowerPC 970 was also dropped as part of some "spring cleaning" of KVM.

The changes for ARM, PowerPC, and S390 were small while most of the new work was focused around the x86/x86_64 KVM support. The x86 code has small performance improvements on "weird guests", hardware-compliancy fixes, APICv fixes, and XSAVES support for hosts and guests.

The full list of KVM changes for Linux 3.19 can be found via the pull request by Paolo Bonzini.
