Verified 5.3.0-25.27/eoan-proposed
** Description changed:
+ [SRU Justification]
+
+ [Impact]
+ There is no complete perf support for Comet Lake CPU. For Ice Lake, some
+ changes has been included in v5.3, but still misses CPU IDs.
+
+ [Fix]
+ perf support for Comet Lake is based on previous works for Ice Lake, so
+ changes for both have to be backported.
+
+ [Test Case]
+ On platforms with Comet Lake/Ice Lake CPUs, one should find new
+ cstate_pkg events c{8,9,10}-residency appear in output of `perf list`
+ for use.
+
+ [Regression Potential]
+ Low. This backports perf support for previously incompletedly supported
+ cpu models.
