From: Shashank Sharma <contactshashanksharma@xxxxxxxxx> 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. - Rename, move and re-arrange some existing structures to differentiate between doorbell handling and VRAM handling. 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.
