From: Shashank Sharma <contactshashanksharma@xxxxxxxxx>
A Memory queue descriptor (MQD) of a userqueue defines it in the
harware's
context. As MQD format can vary between different graphics IPs, we
need gfx
GEN specific handlers to create MQDs.
This patch:
- Introduces MQD hander functions for the usermode queues.
- Adds new functions to create and destroy MQD for GFX-GEN-11-IP
V1: Worked on review comments from Alex:
- Make MQD functions GEN and IP specific
V2: Worked on review comments from Alex:
- Reuse the existing adev->mqd[ip] for MQD creation
- Formatting and arrangement of code
