2.3.7 CBO Box Performance Monitor Event List
The section enumerates performance monitoring events for the CBO Box.
CLOCKTICKS
• Title: Uncore Clocks
• Category: UCLK Events
• Event Code: 0x00
• Max. Inc/Cyc:. 1, Register Restrictions: 0-3
• Definition:
COUNTER0_OCCUPANCY
• Title: Counter 0 Occupancy
• Category: OCCUPANCY Events
• Event Code: 0x1f
• Max. Inc/Cyc:. 20, Register Restrictions: 1-3
• Definition: Since occupancy counts can only be captured in the Cbo's 0 counter, this event allows a
user to capture occupancy related information by filtering the Cb0 occupancy count captured in
Counter 0. The filtering available is found in the control register - threshold, invert and edge
detect. E.g. setting threshold to 1 can effectively monitor how many cycles the monitored queue
has an entry.
