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. |
