This bug is awaiting verification that the linux-azure/6.2.0-1018.18 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-lunar-linux-azure' to 'verification-done-lunar- linux-azure'. If the problem still exists, change the tag 'verification- needed-lunar-linux-azure' to 'verification-failed-lunar-linux-azure'.
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.

The refreshed patches will fix 2 bugs for future Hyper-V versions: 1) PCI DDA for Linux TDX VMs with HCL is not working due to a guest bug and a host bug. The guest bug is fixed in the mainline version of the TDX patches. 2) On a recent Hyper-V dev build that advertises the Hyper-V TLB flushing hypercalls, the current Ubuntu 6.2 kernel passes a shared input page to the Hyper-V while it should pass a private input page; as a result, the hypercall always fails and Linux now falls back to the legacy native method of flusing TLB. This slows down the flush-TLB operation . The mainline version doesn't have the bug. [Test Plan] Microsoft tested. [Regression Potential] Azure instances with TDX on HCL hypervisors may not work correctly.
