2023-08-16drm/amdgpu: skip xcp drm device allocation when out of drm resourceJames Zhu
Return 0 when drm device alloc failed with -ENOSPC in order to allow amdgpu drive loading. But the xcp without drm device node assigned won't be visiable in user space. This helps amdgpu driver loading on system which has more than 64 nodes, the current limitation. The proposal to add more drm nodes is discussed in public, which will support up to 2^20 nodes totally. kernel drm: https://lore.kernel.org/lkml/20230724211428.3831636-1-michal.winiarski@intel.com/T/ libdrm: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/305 Signed-off-by: James Zhu <James.Zhu@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

If xcp_mgr is initialized, add mem_id to amdgpu_vm structure to store memory partition number when creating amdgpu_vm for the xcp. The xcp number is decided when opening the render device, for example /dev/dri/renderD129 is xcp_id 0, /dev/dri/renderD130 is xcp_id 1.

Within a device, an accelerator core partition can be constituted with different IP instances. These partitions are spatial in nature. Number of partitions which can exist at the same time depends on the 'partition mode'. Add a manager entity which is responsible for switching between different partition modes and maintaining partitions. It is also responsible for suspend/resume of different partitions.
