[igt-dev] [PATCH i-g-t v2] tests/kms_cursor_crc: Reduce the execution time on simulation

[Nidhi Gupta <nidhi1.gupta@intel.com>]

As the test execution is taking more time on simulation, limit the
execution to two (first & last) pipes. This optimization is for
simulation and hardware.

This patch will also provide an option (command line flag '-e') to
execute on all pipes.
