Title:
[Hyper-V] IB/mlx5: Respect new UMR capabilities
Status in linux-azure package in Ubuntu:
Confirmed
Status in linux-azure source package in Bionic:
In Progress
Bug description:
In some firmware configuration, UMR usage from Virtual Functions is
restricted.
This information is published to the driver using new capability bits.
Avoid using UMRs in these cases and use the Firmware slow-path flow to create
mkeys and populate them with Virtual to Physical address translation.
Older drivers that do not have this patch, will end up using memory keys that
aren't populated with Virtual to Physical address translation that is done
part of the UMR work.
