摘要： A hosting partition update mechanism allows updating the I/O capability of a logically-partitioned computer system in a way that minimally affects the performance and availability of I/O in the computer system. When an update is needed, a new hosting partition is created with the desired update(s). The I/O adapters in the current hosting partition are then migrated to the new hosting partition. The migration of an I/O adapter from the current hosting partition to the new hosting partition is relatively fast, thereby minimally impacting system performance and availability of I/O. Once all of the I/O adapters have been migrated to the new hosting partition, the current hosting partition may be kept as a backup, or may be eliminated. Providing a new or backup hosting partition allows updates to be performed in the new or backup hosting partition in a non-disruptive manner while the current hosting partition continues to service I/O requests.
摘要翻译： 主机分区更新机制允许以最小程度上影响计算机系统中I / O的性能和可用性的方式更新逻辑分区计算机系统的I / O能力。 当需要更新时，将创建一个新的托管分区，并具有所需的更新。 当前主机分区中的I / O适配器随后被迁移到新的主机分区。 将I / O适配器从当前主机分区迁移到新的主机分区相对较快，从而最小程度上影响了系统性能和I / O的可用性。 一旦所有的I / O适配器都已经迁移到新的主机分区，当前的主机分区可能会保留作为备份，或者可能被删除。 提供新的或备份的主机分区允许在新的或备份主机分区中以不间断的方式执行更新，同时当前的主机分区继续维护I / O请求。

摘要： An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

摘要： At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.
