This is the fourth (and hopefully last) version of the patch-set to add the new subsystem for compute accelerators. I removed the RFC headline as I believe it is now ready for merging. Compare to v3, this patch-set contains one additional patch that adds documentation regarding the accel subsystem. I hope it's good enough for this stage. In addition, there were few very minor fixes according to comments received on v3. The patches are in the following repo: https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/accel.git/log/?h=accel_v4 As in v3, The HEAD of that branch is a commit adding a dummy driver that registers an accel device using the new framework. This can be served as a simple reference. v1 cover letter: https://lkml.org/lkml/2022/10/22/544 v2 cover letter: https://lore.kernel.org/lkml/20221102203405.1797491-1-ogabbay@xxxxxxxxxx/T/ v3 cover letter: https://lore.kernel.org/lkml/20221106210225.2065371-1-ogabbay@xxxxxxxxxx/T/ Thanks, Oded.
