[RFC PATCH 1/3] drivers/accel: add new kconfig and update MAINTAINERS

From: Oded Gabbay
Date: Sat Oct 22 2022 - 17:46:55 EST


Add a new Kconfig for the accel subsystem. The Kconfig currently
contains only the basic CONFIG_ACCEL option that will be used to
decide whether to compile the accel registration code as part of the
drm core functionality.

I have taken the liberty to appropriate the dri-devel mailing list and
the dri-devel IRC channel for the accel subsystem.

+ Framework for device drivers of compute acceleration devices, such
+ as, but not limited to, Machine-Learning and Deep-Learning
+ acceleration devices.
+ If you say Y here, you need to select the module that's right for
+ your acceleration device from the list below.
+ This framework is integrated with the DRM subsystem as compute
+ accelerators and GPUs share a lot in common and can use almost the
+ same infrastructure code.
+ Having said that, acceleration devices will have a different
+ major number than GPUs, and will be exposed to user-space using
+ different device files, called accel/accel* (in /dev, sysfs
+ and debugfs)
