H A D | amdgpu_xcp.c | 400a39f1 Wed Aug 09 15:45:04 CDT 2023 James Zhu <James.Zhu@amd.com> drm/amdgpu: skip xcp drm device allocation when out of drm resource
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
