[igt-dev] [PATCH] tests/ xe_exec_compute_mode: Increase fence timeout for simulation env

[Kamil Konieczny]

Hi Krishnaiah,

small nit: remove space between "tests/" and name of the test:

[PATCH] tests/ xe_exec_compute_mode: Increase fence timeout for simulation env
------------- ^

should be:
[PATCH] tests/xe_exec_compute_mode: Increase fence timeout for simulation env

Regards,
Kamil
