This bug is awaiting verification that the linux-ibm-gt- tdx/6.8.0-1009.10+tdx1 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-noble-linux-ibm-gt-tdx' to 'verification-done-noble-linux-ibm-gt-tdx'. If the problem still exists, change the tag 'verification-needed-noble-linux-ibm-gt-tdx' to 'verification-failed-noble-linux-ibm-gt-tdx'.
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.

They are used as dynamic switching to reduce RF noise. RFIM is already supported in the kernel, this patchset adds the SAGV feature. [Fix] Cherry-pick 6 commits from mainline kernel [Test] Enable the SAGV from the BIOS, booting with the patched kernel, after booting up, run 'systemctl status dtt.service', we will get: service is enabled and service is running run 'cat /sys/kernel/debug/dri/0000:00:02.0/i915_sagv_status', we will get: SAGV available: Yes SAGV status: enabled [Where problems could occur] Because the fix is for i915, it is likely introduce regression on graphic, but this possibility is very low. These 6 commits are merged to mainline kernel from v6.10-rc1, so far there is no regression reported on them. And we tested the patched kernel on different Intel machines, all worked well.
