[igt-dev] [PATCH i-g-t v3 03/11] tests/gem_exec_schedule: use new common functions
Antonio Argenziano
antonio.argenziano at intel.com
Fri Feb 16 00:43:02 UTC 2018
From: Daniele Ceraolo Spurio <daniele.ceraolospurio at intel.com>
With intel_measure_ring_size and igt_cork added as common utilities we
can use them instead of the local copy of those utilities
