[PATCH v2 00/12] Parallel submission of dma fence jobs and LR jobs with shared hardware resources

[Francois Dugast]

v2: The main purpose of this new version is to address (hopefully) all the
comments from Matt on the RFC [1]. Individual commits provide more details about
the changes. This version also adds a dependency to another series [2] on
CPU binds. While the new series of IGT tests [3] designed to test this feature
do pass on PVC, this series still lacks thorough testing and some more or less
sporadic issues are already identified (namely a circular lockdep and failure
waiting for GuC suspend). While I chase those, I am sharing this version already
to get feedback on the resolution of the previous comments and course correct
if needed.
