Subject: [PATCH v3 16/30] perf vendor events: Update Intel jaketown
Update to v21, the metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
to download and generate the latest events and metrics. Manually copy
the jaketown files into perf and update mapfile.csv.
Tested on a non-jaketown with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

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 'special' credits. This statistic is generally not interesting for general IA workloads, but may be of interest for understanding the characteristics of systems using ISOCH. One can filter based on the memory controller channel. One or more channels can be tracked at a given time.",

In order for a request to be transferred across QPI, it must be guaranteed to have a flit buffer on the remote socket to sink into. There are two credit pools, VNA and VN0. VNA is a shared pool used to achieve high performance. The VN0 pool has reserved entries for each message class and is used to prevent deadlock. Requests first attempt to acquire a VNA credit, and then fall back to VN0 if they fail. This counts the number of times a VN0 credit was used. Note that a single VN0 credit holds access to potentially multiple flit buffers. For example, a transfer that uses VNA could use 9 flit buffers and in that case uses 9 credits. A transfer on VN0 will only count a single credit even though it may use multiple buffers.",
