[PATCH 1/3] drm/v3d: decouple adding job dependencies steps from job init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Prep work to enable a job to wait for more than one syncobj before
start. Also get rid of old checkpatch warnings in the v3d_gem file.
No functional changes.
