We’re excited to announce that 1^st part of ACRN codes, regarding to /arch/x86 changes, have been merged into Linux x86 tip tree by maintainer Borislav Petkov (bp@...) . If no big surprise, those patches will be pulled into Linus kernel tree after v5.3-rc.

This is a big step for ACRN upstreaming, which means ACRN begin to sit side by side with XEN, KVM, JAILHOUSE.

We’ll continue our upstream work for the complete ACRN functionality. Stay tuned!
