Xvisor v0.2.7
(Last Commit: 375b8c569071cb8bf543af8b52477e0480f93100)
(Release Date: 14-Nov-2015)
In this release, we have lot of new features, drivers, emulators,
and improvements.
New Features:
- Simple light-weight serial port driver framework
- Boot-time initrd block device creation from device tree
- Support multiple banks of host RAM
- More Linux-like DMA mapping APIs
- Linux compatible NAPI APIs
- Logical SMP IDs for host CPUs based their boot-order
- Support for marking a host IRQ as inter-processor interrupt
- Generic exceptions table APIs
- Separate per-CPU irq handler for per-CPU host IRQs
- Generic PA->VA mappings API using rbtree based hash
- Memory read/write relaxed legacy APIs
- Linux-like vmm_host_irqdomain APIs which handles both static
and extended host IRQs
- Priority-based rate monotonic scheduling algorithm
- Support for async-IPI based wakeup from wait-for-interrupt
- Allow guest regions to be added from emulator probe
- Emulated irqchip construct (i.e. vmm_devemu_irqchip) in
device emulation framework
New Commands:
- mii command similar to Linux mii-tool
- sleep command similar to bash's sleep command
- echo command similar to bash's echo command
- set_affinity sub-command for host irq command
- module_load sub-command for vfs command
New Drivers:
- Micrel PHY driver
- i.MX6 FEC ethernet driver
- BCM2836 local INTC irqchip driver
- i.mx25 clock driver
- i.MX25 pin control driver
New Emulators:
- Generic PCIe host controller emulator (EXPERIEMENTAL)
- Simple pass-through emulator
ARM Ports:
- Use vmm_host_irq_find() to find appropriate IPI for
architecture specific IPI callbacks
ARM32ve Port:
- Lazy context switching of VFP/ASIMD registers
- Force disable coprocessor and system traps in VCPU init
- Raspberry Pi2 (BCM2836 SOC) board support
ARM64 Port:
- Force disable coprocessor and system traps in VCPU init
- Added invalidate_dcache_mva() and invalidate_dcache_mva_range()
x86 Port:
- Fix for a crash on multi-IOAPIC system.
- A lot in port of Intel VMX (currently in nascent state).
- Support for passing initrd to xvisor as root FS.
- Arch implementation of memcpy.
- Default console now can be overridden with console bootrags
- Boot time script for mounting root.
- Wait for block device settling.
- Tested boot on Intel and AMD based desk/laptops.
