• Title: HA iMC CHN0 WPQ Credits Empty - Regular
• Category: WPQ_CREDITS Events
• Event Code: 0x18
• Max. Inc/Cyc:. 4, Register Restrictions: 0-3
• Definition: Counts the number of cycles when there are no “regular” credits available for posting
writes from the HA into the iMC. In order to send writes into the memory controller, the HA must
first acquire a credit for the iMC's WPQ (write pending queue). This queue is broken into regular
credits/buffers that are used by general writes, and “special” requests such as ISOCH writes. This
count only tracks the regular credits Common high bandwidth workloads should be able to make
use of all of the regular buffers, but it will be difficult (and uncommon) to make use of both the
