This bug is awaiting verification that the linux/5.15.0-68.75 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.

Intel has customers that would like to use the intel_idle driver on latest SPR (Sapphire Rapids). These patches have all landed upstream, but are not in Jammy. These patches will enable customers to use Ubuntu 22.04 on new hardware from Intel. == Fixes == 9edf3c0ffef0 ("intel_idle: add SPR support") da0e58c038e6 ("intel_idle: add 'preferred_cstates' module argument") 3a9cf77b60dc ("intel_idle: add core C6 optimization for SPR") 03eb65224e57 ("cpuidle: intel_idle: Drop redundant backslash at line end") 39c184a6a9a7 ("intel_idle: Fix the 'preferred_cstates' module parameter") 7eac3bd38d18 ("intel_idle: Fix SPR C6 optimization") 1548fac47a11 ("intel_idle: make SPR C1 and C1E be independent") == Regression Potential == Medium. These patches are specific to enable intel_idle support for Sapphire Rapids. Changes are specific to Intel and tested by Intel. == Test Case == A test kernel was built with these patches and tested by Intel. Intel tested on SPR-SP machine and see the correct 190us and 600us residency for the C6 state.
