Subject: [PATCH 1/2] tools/power/x86/intel-speed-select: Fix display for turbo-freq auto mode
Date: Thu, 30 Jan 2020 21:45:17 -0800 [thread overview]
Message-ID: <20200131054518.1644519-1-srinivas.pandruvada@linux.intel.com> (raw)
When mailbox command for the turbo-freq enable fails, then don't display
result for auto-mode. When turbo-freq enable fails, there is no point
to set CPU priorities.
