[Fix] * https://lkml.org/lkml/2019/11/18/713 ("platform/x86: intel_pmc_core: Add Comet Lake (CML) platform support to intel_pmc_core driver") [Test Case] 1. install prebuilt kernels from ppa:vicamo/ppa-1847450 2. boot with installed kernel and check if /sys/kernel/debug/pmc_core is then available. [Regression Potential] Low. This only adds two new IDs to a model white list and doesn't change behavior of existing systems. ========== original bug description ========== Description Cometlake -S 6+2 is using a different CPU Model number: DEC 165, HEX: A5 We need the intel_pmc_core driver patch to support CML-S6+2 Target Kernel: 5.5 Target Release: 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1847450/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
