I'm wondering if I can monitor dispatch stalls caused by the SQ being full.
The K15 BKDG does not list a counter for this circumstance.
When I run a program under CodeAnalyst, and measure all the events in the dispatch stall category, I find that the individual events don't come anywhere close to the total (event 0D1) dispatch stalls. My program also shows a large number of cycles where the SQ is full, enough to account for the missing dispatch stalls.
This is a question for AMD staff, most likely. What I want to know is, (1) does STQ Full result in dispatch stalls? (2) Assuming this is so, is there a PMC event that counts these, which somehow was omitted from the BKDG and from CodeAnalyst, and what would be the event number for it?
