Subject: [PATCH 6/8] cpupower: Condense pstate enabled bit checks in decode_pstates()
Date: Fri, 22 Jan 2021 11:39:14 -0600 [thread overview]
Message-ID: <161133715479.59625.495972759377981936.stgit@ethanol01c7-host.amd.com> (raw)
In-Reply-To: <161133705833.59625.6935511700675018185.stgit@ethanol01c7-host.amd.com>
The enabled bit (bit 63) is common for all families so we can remove
the multiple enabled checks based on family and have a common check
for HW pstate enabled.
