From 47e91cc220962fef2ad5afd1ce39fea1cec52f95 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Tue, 5 Feb 2019 16:26:16 +0000 Subject: tools/intel_gpu_top: Add support for stdout logging Two new output modes are added: listing of text data to standard out (-l on the command line), and dumping of JSON formatted records (-J), also to standard out. The first mode is selected automatically when non-interactive standard out is detected. Example of text output: Freq MHz IRQ RC6 Power IMC MiB/s RCS/0 BCS/0 VCS/0 VCS/1 VECS/0 req act /s % W rd wr % se wa % se wa % se wa % se wa % se wa 0 0 0 0 0.00 360 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 35 2 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 34 2 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 143 6 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 169 7 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 169 7 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 Example of JSON output: { "period": { "duration": 1002.525224, "unit": "ms" }, "frequency": { "requested": 349.118398, "actual": 349.118398, "unit": "MHz" }, "interrupts": { "count": 0.000000, "unit": "irq/s" }, "rc6": { "value": 99.897752, "unit": "%" }, "power": { "value": 0.000000, "unit": "W" }, "imc-bandwidth": { "reads": 149.683843, "writes": 6.104093, "unit": "MiB/s" }, "engines": { "Render/3D/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Blitter/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Video/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Video/1": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "VideoEnhance/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" } } } v2: * Show example output in commit message. * Install signal handler to complete output on SIGINT.
