[PATCH v2 0/8] Re-design doorbell framework for usermode queues

[Shashank Sharma]

From: Shashank Sharma <contactshashanksharma at gmail.com>

This patch series re-designs the current doorbell handling of the AMDGPU
driver and prepares it for Usermode queues. The fundamental changes are:

- Introduce and accommodate a new GEM domain for doorbells.
- Prepare the AMDGPU ttm backend for handling doorbell memory.
- Create a doorbell BO for kernel-level doorbell opertations.
- Rename, move and re-arrange some existing structures.

The idea is that a usermode app can directly allocate a page from
the doorbell bar and use it's offsets for different usermode queues.

Corresponding libdrm changes (just addition of this new flag):
