摘要： File system sharing in multi-host computing system (100) running multiple operating systems is described herein. A file systems stored on different data partitions (110-1) and (110-1), of different operating systems (106-1) and (106-2), running on a multi-host computing system (100) may be shared based on file server-client architecture. According to the implementation, an operating system (106-1) may share its file system as file server and other operating system (106-2) may access the shared file system as file client. In one implementation, the sharing of data between multiple hosts is enabled by a dedicated high speed, low latency, inter processor communication bus, FiRE (124).
摘要翻译：这里描述了运行多个操作系统的多主机计算系统（100）中的文件系统共享。存储在多主机计算系统（100）上运行的不同操作系统（106-1）和（106-2）的不同数据分区（110-1）和（110-1））上的文件系统可以被共享基于文件服务器 - 客户端架构。根据该实现，操作系统（106-1）可以作为文件服务器共享其文件系统，而其他操作系统（106-2）可以作为文件客户端访问共享文件系统。在一个实现中，通过专用的高速，低延迟的处理器间通信总线FiRE（124）来实现多个主机之间的数据共享。

摘要： Described herein are methods and systems for virtualization of a USB device to enable sharing of the USB device among a plurality of host processors in a multi-processor computing system. A USB virtualization unit for sharing of the USB device include a per-host register unit, each corresponding to a host processor includes one or more of a host register interface, host data interface, configuration registers, and host control registers, configured to receive simultaneous requests from one or more host processors from amongst the plurality of host processors for the USB device. The USB virtualization unit also includes a pre-fetch direct memory access (DMA) configured to pre-fetch DMA descriptors associated with the requests to store in a buffer. The USB virtualization unit further includes an endpoint specific switching decision logic (ESL) configured to schedule data access based on the DMA descriptors from the host processor's local memory corresponding to each request.

摘要： Described herein is a multi-host peripheral controller configured to allow a plurality of host processors to simultaneously access the I/O devices through one of a per-host dedicated system bus architecture and common system bus architecture. Such a bus architecture is one of AXI, AHB, PCI, PCIe, OCP, etc. The multi-host peripheral controller allows operating systems, running on the plurality of host processors, to operate asynchronously with minimal or no inter operating system dependency. For addressability, either address based or sideband signal based demarcation may be used.
摘要翻译：这里描述的是多主机外围控制器，被配置为允许多个主机处理器通过每个主机专用系统总线架构和公共系统总线架构之一来同时访问I / O设备。这种总线架构是AXI，AHB，PCI，PCIe，OCP等之一。多主机外围控制器允许在多个主机处理器上运行的操作系统以最小或没有操作系统依赖性异步运行。对于可寻址性，可以使用基于地址或基于边带信号的分界。
