Subject: [PATCH] kms/nv50-: Initialize core channel in
|
|
nouveau_display_create()
|
|
|
|
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.
