This bug is awaiting verification that the linux/5.4.0-97.110 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

For instance VMAs created with io_remap_pfn_range(), or other driver special VMA. For ranges the interface understands it can provide a DMA mapped sg_table for use by the ib_umem, allowing user virtual ranges that cannot be supported by get_user_pages() to be used as umems for RDMA. This is designed to preserve the kABI, no functions or structures are changed, only new symbols are added: ib_register_peer_memory_client ib_unregister_peer_memory_client ib_umem_activate_invalidation_notifier ib_umem_get_peer And a bitfield in struct ib_umem uses more bits. This interface is compatible with the two out of tree GPU drivers: https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/blob/master/drivers/gpu/drm/amd/amdkfd/kfd_peerdirect.c https://github.com/Mellanox/nv_peer_memory/blob/master/nv_peer_mem.c To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1923104/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
