radeon_cs_emit did not trigger, but ProcGetInputFocus causes some activity

Yes, what I actually wanted was a tool that traces every single function call
and outputs the call chain for every single function call but there doesn't
seem to be much in that regard except gdb scripting or long abandoned tools.

It does not trigger. On the other hand it also does not trigger when running a
3d application like xonotic on the radeon gpu. So here's another maybe useless
gdb log (radeon_cs_emit was Breakpoint 1)...
