Public bug reported: [Impact]
During AMD Genoa development, the datacenter team identified performance regressions that were root caused in the amd-pstate driver. A first round of fixes already landed upstream (v6.1-rc7) in the amd-pstate driver, and should be backported to all the affected kernels.
