Add amdxdna_gem_prime_export() and amdxdna_gem_prime_import() for BO import and export. Register mmu notifier for imported BO as well. When MMU_NOTIFIER_UNMAP event is received, queue work to remove the notifier. The same BO could be mapped multiple times if it is exported and imported by an application. Use a link list to track VMAs the BO been mapped. v2: Rebased and call get_dma_buf() before dma_buf_attach() v3: Removed import_attach usage Reviewed-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Link: https://lore.kernel.org/r/20250325200105.2744079-1-lizhi.hou@amd.com
