Bug Description
GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU.
This functionality has been enabled in all previous kernel versions and needs to be in this kernel so there is no loss of functionality for users.

This bug is awaiting verification that the linux-nvidia- 6.8/6.8. 0-1006. 6~22.04. 2 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- jammy-linux- nvidia- 6.8' to 'verification- done-jammy- linux-nvidia- 6.8'. If the problem still exists, change the tag 'verification- needed- jammy-linux- nvidia- 6.8' to 'verification- failed- jammy-linux- nvidia- 6.8'.
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. Thank you!
