[PATCH 16/23] drm/amdgpu: add flag to indicate VF runtime state

Guest driver will select using KIQ to access gpu registers if runtime flas is set, or will use MMIO method to r/w registers directly. When VF's initialization is done, VF should use set runtime flag and use KIQ method. And clear runtime flag when starting to unload driver. Signed-off-by: Monk

[PATCH 00/23] Add support AMD GPU virtualization soultion

This patch series will enable AMD GPU virtualization and wires it into amdgpu modules. The code design is base on below ideas: 1. Make virtualization code independent; 2. Self-maintain related GPU virtualization codes; 3. Easy to maintain virtualization codes; 4. Reduce the influence on other

[PATCH 03/23] drm/amdgpu: export KIQ interfaces

[PATCH 07/23] drm/amdgpu: create new directory for GPU virtualization

Create new directory for GPU virtualization and name it with marketing name, so it will easy to mantainer all realted virtual code and make it independent so that will not affect other parts. And create new pointer and interface to connect virtualization code with amdgpu core code.

[PATCH 01/23] drm/amdgpu: add support kernel interface queue(KIQ)

KIQ is queue-memory based initialization method: setup KIQ queue firstly, then send command to KIQ to setup other queues, without accessing registers. For virtualization, need KIQ to access virtual function registers when running on guest mode. Signed-off-by: Xiangliang Yu
