摘要： A system for making a determination to send a synchronous or asynchronous resource request. In response to sending a request to receive response time data for resource requests, the response time data for resource requests is received and stored. A request from a requester is received for response time data for a particular type of resource request. The response time data for the resource requests is searched for the particular type of resource request. In response to finding the response time data for the particular type of resource request within the response time data for the resource requests, the response time data for the particular type of resource request is sent to the requester. The requester either sends a synchronous or asynchronous resource request based on the response time data for the particular type of resource request.

摘要： A mechanism for generating pre-translated segments for use in virtual to real address translation is provided in which segments that are determined to meet a density threshold are promoted to a pre-translated segment class. The pages of these segments are moved to a contiguous portion of memory and the segment table entry corresponding to the segment is updated to indicate the segment to be a pre-translated segment and to include the base real address for the contiguous portion of memory. In one embodiment, as each page is moved, its page table entry is updated to point to the new location of the page so that the page is still accessible during promotion of the segment to a pre-translated segment. In this way, virtual-to-real address translation may be performed by concatenating the segment base real address, the page identifier, and a byte offset into the page.

摘要翻译： 提供了一种用于生成用于虚拟到实际地址转换的预翻译段的机制，其中被确定为满足密度阈值的段被提升为预先转换的段类。 这些段的页面被移动到存储器的连续部分，并且对应于段的段表条目被更新以指示段作为预转换段并且包括存储器的连续部分的基本实地址。 在一个实施例中，当每个页面被移动时，其页表条目被更新以指向该页面的新位置，使得该页面在该段的推广期间仍可访问到预翻译的段。 以这种方式，可以通过将段基本实地址，页标识符和字节偏移连接到页中来执行虚拟到实地址转换。
