New Features:

• Generic LIFO & FIFO APIs under libs/common
• VirtIO based paravirtualization
• Lazy port-to-switch transfers in network switch
• Lookup based clock device (clkdev) framework
• Light-weight MMC/SD/SDIO framework
• Block device partitioning
• Faster Orphan VCPU preemption using arch_vcpu_preempt_orphan()
• Boot time or early parameters to hypervisor

New Drivers:

• IMX serial port driver
• PL180 MMCI driver
• Generic SDHCI driver
• BCM2835 SDHCI driver
• I8042 keyboard and mouse controller driver

New Emulators:

• VirtIO MMIO transport emulator
• VirtIO Network device emulator
• VirtIO Block device emulator
• VirtIO Console device emulator
• ARM11MPCore emulator

MIPS 32-bit Port:

• The MIPS port is orphaned since long time and currently broken
• From this release, we remove MIPS port and hope that someone will fix and add it back later

ARM 32-bit Port:

• Added support for ARMv6 CPUs
• Added support for Realview-EB-MPCore
• Added support for Raspberry Pi (BCM2835 SOC)
• Added support for KZM (i.MX31 SOC)
• Added support for 3DS (i.MX25 SOC)
• Added Realview-EB-MPCore guest for ARMv6 host
• Added CPU specific quirks and errata implementations
• Fixed cache operations for ARMv5, ARMv6 and ARMv7 CPUs
• Implemented arch_vcpu_preempt_orphan() for Orphan VCPUs
• Added support for external DTB provided by bootloaders

ARM 32-bit with VE Port:

• Added stubs and macros for adding VGIC assisted GIC emulation
• Implemented arch_vcpu_preempt_orphan() for Orphan VCPUs
• Added support for external DTB provided by bootloaders

x86_64 Port:

• Fixed context switching
• Fixed HPET timer
• Fixed IOAPIC driver
• Populate device tree from ACPI tables
• Got Xvisor x86_64 prompt working on QEMU using AT-keyboard and text mode framebuffer
