Xvisor v0.1.2 Date: Tue, 28 Feb 2012 19:01:59 +0530  |  Posted by: Anup Patel

In this release, we added few features, cleaned-up our code, and formalized our coding-style document.

New Features:

• Wait-for-interrupt support in VCPU irq subsystem
• Dynamic guest creation/destruction
• Device clock managment support in device driver framework
• RTC device framework
• Wall-clock subsystem for tracking real-time
• PL031 RTC emulators

ARM 32-bit Port:

• Replaced wfi instruction with a new hypercall. The new hypercall uses wait-for-interrupt feature of VCPU irq subsystem.
• Added support for VCPU deinit required for destroying a VCPU
• Linux guest is able to sync date/time from emulated RTC
• Added support for emulating cache operations
• Xvisor ARM running on BeagleBoard-xM is able to boot Linux kernel on Realview-PB-A8 guest

MIPS 32-bit Port:

• Xvisor MIPS boots up and gets to managment terminal.
• Guest support in Xvisor MIPS is still work-in-progress.

x86 64-bit Port:

• Initial compilable code for supporting Intel x86_64
