摘要： Mechanisms for differentiating traffic types in a multi-root PCI Express environment are provided. The mechanisms generate a first mapping data structure that, for each single-root virtual hierarchy in the multi-root data processing system, associates a plurality of traffic classes with a plurality of priority groups and maps each traffic class in the plurality of traffic classes to a corresponding virtual channel in a plurality of virtual channels. Moreover, a second mapping data structure is generated that maps each virtual channel in the plurality of virtual channels to corresponding virtual link in a plurality of virtual links of the multi-root data processing system. Traffic of a particular priority group is routed from a single-root virtual hierarchy to a particular virtual link in the plurality of the virtual links based on the first mapping data structure and second mapping data structure.

摘要： Mechanisms for enabling both native and non-native input/output virtualization (IOV) in a single I/O adapter are provided. The mechanisms allow a system with a large number of logical partitions (LPARs) and system images to use IOV to share a native IOV enabled I/O adapter or endpoint that does not implement the necessary number of virtual functions (VFs) for each LPAR and system image. A number of VFs supported by the I/O adapter, less one, are assigned to LPARs and system images so that they may make use of native IOV using these VFs. The remaining VF is associated with a virtual intermediary (VI) which handles non-native IOV of the I/O adapter. Any remaining LPARs and system images share the I/O adapter using the non-native IOV via the VI. Thus, any number of LPARs and system images may share the same I/O adapter or endpoint.
摘要翻译：提供了在单个I / O适配器中实现本机和非本机输入/输出虚拟化（IOV）的机制。这些机制允许具有大量逻辑分区（LPAR）和系统映像的系统使用IOV来共享不为每个LPAR实现必需数量的虚拟函数（VF）的本机IOV使能的I / O适配器或端点，系统图像。 I / O适配器支持的多个VF分配给LPAR和系统映像，从而可以利用这些VF使用本机IOV。剩余的VF与处理I / O适配器的非本地IOV的虚拟中介（VI）相关联。任何剩余的LPAR和系统映像都使用非本机IOV通过VI共享I / O适配器。因此，任何数量的LPAR和系统映像可以共享相同的I / O适配器或端点。

摘要： Mechanisms to address the situation where an input/output (I/O) fabric is shared by more than one logical partition (LPAR) and where each LPAR can share with the other LPARs an I/O adapter (LOA) are provided. In particular, each LPAR is assigned its own separate address space to access a virtual function (VF) assigned to it such that each LPAR's perception is that it has its own independent IOA. Each VF may be shared across multiple LPARs. Facilities are provided for management of the shared resources of the IOA via a Physical Function (PF) of the IOA by assignment of that PF to an I/O Virtualization Management Partition (IMP). The code running in the IMP acts as a virtual intermediary to the VFs for fully managing the VF error handling, VF reset, and configuration operations. The IMP also acts as an interface to the PF for accessing common VF functionality. Furthermore, the functions of resource assignment and management relative to the VFs and the client partitions that use those VFs, which might normally be done by an entity like a hypervisor, are implemented by this IMP.

摘要： Mechanisms are provided for implementing a multi-root PCI manager (MR-PCIM) in a multi-root I/O virtualization management partition (MR-IMP) to control the shared functionality of an multi-root I/O virtualization (IOV) enabled switch fabric and multi-root IOV enabled I/O adapter (IOA) through the base functions (BF) of the switches and IOAs. A hypervisor provides device-independent facilities to the code running in the I/O Virtualization Management Partition (IMP), Multi-Root (MR)-IMP and client partitions. The MR-IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the switch and IOA's control functions.

摘要： A hypervisor, during device discovery, has code which can examine the south-side management data structure in an adapter's configuration space and determine the type of device which is being configured. The hypervisor may copy the south-side management data structure to a hardware management console (HMC) and the HMC can populate the data structure with south-side data and then pass the structure to the hypervisor to replace the data structure on the adapter. In another embodiment the hypervisor may copy the data structure to the HMC and the HMC can instruct the hypervisor to fill-in the data structure, a virtual function at a time, with south-side management data associations. The administrator can assign south-side data, such as a MAC address for a virtual instance of an Ethernet device, to LPARs sharing the adapter. Thus, a standard way to manage the south-side data of virtual functions is provided.
