[igt-dev] [PATCH i-g-t 03/14] benchmarks/gem_wsim: fix scaling of period steps

[Marcin Bernatowicz]

Period steps take scale time (-F) command line option into account.
This allows to scale workload without need to modify .wsim file

ex. having following example.wsim

1.VCS1.3000.0.1
1.RCS.500-1000.-1.0
1.RCS.3700.0.0
1.RCS.1000.-2.0
1.VCS2.2300.-2.0
1.RCS.4700.-1.0
1.VCS2.600.-1.1
p.16000

we can scale the whole workload x10 with:

gem_wsim -w example.wsim -f 10 -F 10

-f is for batch duration steps, -F for period and delay steps
