Tracing the GPU usage
Hello,
Can give me some tips to trace the GPU usage on a solaris8 update7 box?
I try to understand why a Cadcam app is so slow on my Solaris box compared to a win$ box. I guess it comes from the poor graphic card I have but i would like to emphasize it.
My bench is 150sec long on a Solaris while 33sec long on Win$
Using vmstat and iostat I can see that there is no disk swap that could slow the app. The cpu is spent, at 95%, as user CPU. The truss -c cmd shows that the overall system time is 13sec (over 150sec) with 12 secs of ioctl!
As it's a graphic app I guess the system is wating for "GPU results". HOW can I trace it from a system point of view (I don't want to use development mathematics library to trace the process)? The only stuff I have found is fbconfig -prconf that gaves me the video memory usage...
Many thanks for your help.

trace-cmd list [OPTIONS] DESCRIPTION
The trace-cmd(1) list displays the available plugins, events or Ftrace options that are configured on the current machine. If no option is given, then it lists all plugins, events and Ftrace options to standard output. OPTIONS
-e This option will list the available events that are enabled on the local system. -t This option will list the available tracers that are enabled on the local system. -p Same as -t and only for legacy purposes. -o This option will list the available Ftrace options that are configured on the local system. -f [regex] This option will list the available filter functions. These are the list of functions on the system that you can trace, or filter on.
