Bug Description

[SRU Justification]

[Impact]

Current linux-bluefield kernel reports that PCI BARs larger than 128GB are disabled.

Increase the maximum PCI BAR size from 128GB to 8TB for future expansion.

[Test Plan]

Use updated kernel with PCI device with PCI BARs larger than 128GB.

[Where problems could occur]

No potential problems are expected.

[Other Info]

Testing has been provided by the customer. This patch is a cherry-pick from the upstream 5.18 kernel. It is intended for linux-bluefield kernel re-spin but it may be also suitable for the generic kernel (separate submission).

This bug is awaiting verification that the linux-bluefield/5.15.0-1027.29 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' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
