[PATCH] drm/amdgpu: change kgd2kfd_init_zone sequence during device_init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move kgd2kfd_init _zone_device() after release_full_gpu()
as it takes long time for asics with huge bar size and it could
potentially hit full access timeout for SRIOV during init.
