2022-02-18perfmon: show distribution of uops delivered to frontendRay Kinsella1-1/+2
Breakdown the distribution of uops delivered to the frontend. Collerates directly with the source of the uops. Type: improvement Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: I93a57dbe56dfa0f378527844aa4e63f45a548e55
2022-01-30perfmon: topdown level 1 and 2 for icxRay Kinsella1-0/+1
Topdown level 1 and 2 for Intel Ice Lake (ICX). Limiting topdown support to THREAD for the moment on Ice Lake, as NODE support is still unreliable. Also removing Topdown Level 1 from Sapphire Rapids onwards, as Topdown LeveL 2 also shows Level 1 on Sapphire, and it reduces the overall number of bundles.

2018-12-17Improve perfmon json table pickerDave Barach1-0/+8
Built a tool to chew up https://download.01.org/perfmon/mapfile.csv, and output a table in this format: typedef struct { u8 model; u8 stepping; u8 has_stepping; char *filename; } file_by_model_and_stepping_t; static const file_by_model_and_stepping_t fms_table [] = { /* model, stepping, stepping valid, file */ { 0x2E, 0x0, 0, "NehalemEX_core_V2.json" }, { 0x1E, 0x0, 0, "NehalemEP_core_V2.json" }, <snip> { 0x55, 0x5, 1, "cascadelakex_core_v1.00.json" }, { 0x55, 0x6, 1, "cascadelakex_core_v1.00.json" }, { 0x55, 0x7, 1, "cascadelakex_core_v1.00.json" }, <snip> Change-Id: Ie0e8a7e851799e9d060b966047745039c066ec7b Signed-off-by: Dave Barach <dave@barachs.net>
2018-10-25Add x86_64 perfmon tablesDave Barach1-18/+5
The license issue is resolved, so we can package the .json files. Added to the vpp-dev package in .tar.xz form, which saves a lot of space. Updated the perfmon error log entry: tell folks where to find the compressed tarball, and how to extract it.
