Subject: [PATCH] tools/power turbostat: Add Elkhart Lake support
Date: Thu, 9 Jan 2020 17:17:01 +0800 [thread overview]
Message-ID: <20200109091701.8197-1-yu.c.chen@intel.com> (raw)
Elkhart Lake(TREMONT) succeed GOLDMONT, reuse the code.
Elkhart Lake does not support group turbo limit counter
register and might trigger failure in has_turbo_ratio_group_limits(),
so it is not applicable to reuse GOLDMONT cpuid in intel_model_duplicates().
