what are the meaning of intel_gpu_top information when encoding by qsv

[wang_x_]

Hello!

         I use qsv to encoder 8 video streams ( mpegts udp --> h264 rtmp,  720P), and watch gpu usage by intel_gpu_top.  because we use msdk 1024 in our encoder product, so I can't use metrics_monitor in product. I googled but not found the meaning of intel_gpu_top output.  

          What are the meaning of  intel_gpu_top information: render, bitsteam, GAM, TSG, VFE, TDG?   Thanks very much !

Hi,

To understand the “Intel_GPU_top”  tool and these acronyms, I suggest to take a look at Intel Open source website. here: https://01.org/linuxgraphics/documentation/driver-documentation-prms/2014-2015-intel-processors-based-broadwell-platform

You can read Volume 1: Preface first which includes main terminology table, and try search the acronyms in all documents.

For example:

Extended Math Unit(EMU)

Thanks,

I have only found VFE(video front end).  However, thanks very much.
