[igt-dev] [PATCH i-g-t] lib/gt: Make use of dummyload library to create recursive batch
Chris Wilson
chris at chris-wilson.co.uk
Fri Jul 13 10:06:40 UTC 2018
From: Antonio Argenziano <antonio.argenziano at intel.com>
An hanging batch is nothing more than a spinning batch that never gets
stopped, so re-use the routines implemented in dummyload.c.
v2: Let caller decide spin loop size
v3: Only use loose loops for hangs (Chris)
v4: No requires
v5: Free the spinner
v6: Chamelium exists.
