摘要： Disclosed are a method and system for address translation with memory windows. The method comprises the steps of designating a memory region having a set of virtual addresses, each virtual address having an associated real address; and providing one or more translation tables for translating the virtual addresses to the real addresses; A memory region protection table entry (MRPTE) defines access rights for the memory region, and includes one or more pointers to the one or more translation tables. A memory window is bound to the memory region to provide access to a subset of the virtual addresses. A memory window protection table entry (MWPTE) defines access rights for the memory window, and includes one or more pointers to the one or more translation tables to translate the subset of virtual addresses to real addresses.

摘要： Multiple logical partitions are provided access to a self-virtualizing input/output device of a data processing system via multiple dedicated partition adjunct instances. Access is established by: interfacing each logical partition to one or more associated partition adjunct instances, each partition adjunct instance coupling its associated logical partition to one of a virtual function or a queue pair of the self-virtualizing input/output device, and each partition adjunct instance being a separate dispatchable state and being created employing virtual address space donated from the respective logical partition or a hypervisor of the data processing system, and each partition adjunct instance including a device driver for the virtual function or queue pair of the self-virtualizing input/output device; and providing each logical partition with at least one virtual input/output which is interfaced through the logical partition's respective partition adjunct instance(s) to a virtual function or queue pair of the self-virtualizing input/output device.

摘要： A firmware update process for a self-virtualizing IO resource such as an SRIOV adapter is incorporated into a platform firmware update process to systematically update the resource firmware in a manner that is for the most part transparent to the logical partitions sharing the adapter. In particular, resource firmware associated with a self-virtualizing IO resource is bundled with firmware for at least one adjunct partition associated with that self-virtualizing IO resource within a common firmware image so that, upon restart of the adjunct partition to use the updated firmware image, the resource firmware is also updated, with a logical partition that uses the self-virtualizing IO resource maintained in an active state during the restart, and without requiring the self-virtualizing IO resource to be deconfigured from the logical partition.

摘要： A virtual function mapping process, which is capable of being used in connection with the migration of a logical partition to a target system, creates candidate lists for virtual functions assigned to the logical partition, which are populated with candidate physical ports from a target system that are capable of being mapped to such virtual functions. Candidate physical ports are assigned weights based upon their suitability to be mapped to a particular virtual function, and as candidate physical ports are selected for virtual functions, weights for other candidate physical ports for other virtual functions are recalculated to reflect the impact of the selection of candidate physical ports on the suitability of the remaining physical ports for other virtual functions.

摘要： A computer implemented method of managing an adapter includes determining that an adapter is assigned to an operating system and generating a single root input/output virtualization (SR-IOV) function associated with the adapter. The SR-IOV function may be correlated to a non-SR-IOV function, and the non-SR-IOV function may be used to modify an operational status of the adapter.

摘要： Error handling is simplified for a self-virtualizing IO resource that utilizes a physical function adjunct partition for a physical function in the self-virtualizing IO resource to coordinate error recovery for the self-virtualizing IO resource, by restarting each virtual function adjunct partition associated with that physical function to avoid the need to coordinate error recovery within the logical partitions to which such virtual function adjunct partitions are assigned.

摘要： Frame wrapping such as Q-in-Q frame wrapping is used to enforce QoS prioritization with a converged or multi-function self-virtualizing IO resource such as a converged SRIOV network adapter. Frame wrapping may be used to avoid conflicting priorities from frames associated with virtual functions for which ACLs are not enforced, and thereby preserve QoS prioritization for lossless traffic classes.

摘要： In various embodiments a traffic class manager is a resource within a virtualized computer systems trusted entity (i.e. a hypervisor, trusted partition, etc.) which maps requirements from a platform management and associated network capabilities onto an SR-IOV adapter in order to appropriately allocate SR-IOV adapter and network resources to the virtualized computer partitions. In various embodiments the traffic class manager defines network traffic classes that meet the objectives of a platform administrator based on the capabilities of the SR-IOV adapter and the network attached to the adapter ports. Once the traffic classes are defined, in various embodiments, the traffic class manager enforces the assignment of a traffic class to a virtual interface queue pair within a partition.

摘要： A vendor independent partition interface between a logical partition and an adjunct partition associated with a self-virtualizing IO resource is used to effectively abstract away vender-specific interface details for the self-virtualizing IO resource. By doing so, vender-specific implementation details may be isolated from the operating systems resident in logical partitions, thus requiring only changes in vendor specific firmware in order to support new or revised self-virtualizing IO resources.
摘要翻译：逻辑分区和与自身虚拟化IO资源相关联的辅助分区之间的供应商独立分区接口用于有效地抽取自身虚拟化IO资源的特定于供应商的接口细节。通过这样做，特定于供应商的实施细节可能与驻留在逻辑分区中的操作系统隔离，因此仅需要修改供应商特定的固件，以便支持新的或修改的自我虚拟化的IO资源。
