From c97cda421f4d5c34638423fb7e07e7968703e619 Mon Sep 17 00:00:00 2001 From: Lukasz Anaczkowski Date: Tue, 21 Jul 2015 10:41:13 +0200 Subject: intel_pstate: Add get_scaling cpu_defaults param to Knights Landing commit 69cefc273f942bd7bb347a02e8b5b738d5f6e6f3 upstream. Scaling for Knights Landing is same as the default scaling (100000). When Knigts Landing support was added to the pstate driver, this parameter was omitted resulting in a kernel panic during boot.
