[igt-dev] [PATCH] [PATCH i-g-t] tests/i915/gem_double_irq_loop: Removal of test

[priyanka.dandamudi at intel.com]

From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

Test tries to detect the missed irq's by executing one large and small batches in a loop 
which has been covered in gem_sync. So,removing the test.
