--- Comment #82 from James Zhu (jamesz@amd.com) --- Hi @kolAflash,
I don't have issue with your .config. on ubuntu 20.04
From source code, it should be fine.
$ grep -rn "kgd2kfd_resume_iommu" drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h 309:int kgd2kfd_resume_iommu(struct kfd_dev *kfd);
$ grep -rn "amdgpu_amdkfd.h|kgd2kfd_resume_iommu" drivers/gpu/drm/amd/amdkfd/kfd_device.c 31:#include "amdgpu_amdkfd.h" 604: kfd->pci_atomic_requested = amdgpu_amdkfd_have_atomics_support(kgd);
792: if (kgd2kfd_resume_iommu(kfd))
940:int kgd2kfd_resume_iommu(struct kfd_dev *kfd)
Looks we are using different 5.10, should we use 5.10 stable for adding this backport patches?.
