Subject: [PATCH v1 27/51] perf vendor events intel: Refresh silvermont events
Date: Sun, 19 Feb 2023 01:28:24 -0800	[thread overview]
Message-ID: <20230219092848.639226-28-irogers@google.com> (raw)
In-Reply-To: <20230219092848.639226-1-irogers@google.com>

Update the silvermont events from 14 to 15. Generation was done using
https://github.com/intel/perfmon.

The most notable change is in corrections to event descriptions.

This event can be used to identify if the machine is truly front-end bound.  When this event occurs, it is an indication that the front-end of the machine is operating at less than its theoretical peak performance.  Background: We can think of the processor pipeline as being divided into 2 broader parts: Front-end and Back-end. Front-end is responsible for fetching the instruction, decoding into micro-ops (uops) in machine understandable format and putting them into a micro-op queue to be consumed by back end. The back-end then takes these micro-ops, allocates the required resources.  When all resources are ready, micro-ops are executed. If the back-end is not ready to accept micro-ops from the front-end, then we do not want to count these as front-end bottlenecks.  However, whenever we have bottlenecks in the back-end, we will have allocation unit stalls and eventually forcing the front-end to wait until the back-end is ready to receive more UOPS. This event counts the cycles only when back-end is requesting more uops and front-end is not able to provide them. Some examples of conditions that cause front-end efficiencies are: Icache misses, ITLB misses, and decoder restrictions that limit the the front-end bandwidth.",
