-Subject: thermal: intel: powerclamp: Fix cur_state for multi package system
-
-From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
-
-commit 8e47363588377e1bdb65e2b020b409cfb44dd260 upstream.
-
-The powerclamp cooling device cur_state shows actual idle observed by
-package C-state idle counters. But the implementation is not sufficient
-for multi package or multi die system. The cur_state value is incorrect.
-On these systems, these counters must be read from each package/die and
-somehow aggregate them. But there is no good method for aggregation.
-
-It was not a problem when explicit CPU model addition was required to
-enable intel powerclamp. In this way certain CPU models could have
-been avoided. But with the removal of CPU model check with the
-availability of Package C-state counters, the driver is loaded on most
-of the recent systems.
-
-For multi package/die systems, just show the actual target idle state,
-the system is trying to achieve. In powerclamp this is the user set
-state minus one.
-
-Also there is no use of starting a worker thread for polling package
-C-state counters and applying any compensation for multiple package
-or multiple die systems.
-
-Fixes: b721ca0d1927 ("thermal/powerclamp: remove cpu whitelist")
