[PATCH v2 1/5] drm/nouveau/kms/nv50-: Initialize core channel in nouveau_display_create()

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

 



We'll need the core channel initialized and ready by the time that we
start creating modesetting objects, so that we can call the
NV507D_GET_CAPABILITIES method to make the hardware expose it's
modesetting capabilities for later probing.

So, when loading the driver prepare the core channel from within
nouveau_display_create(). Everywhere else, we initialize the core
channel during resume.
