Subject: [PATCH v3 2/6] cpufreq: amd-pstate: Only show shared memory solution message once
Date: Thu, 14 Apr 2022 11:47:57 -0500 [thread overview]
Message-ID: <20220414164801.1051-3-mario.limonciello@amd.com> (raw)
In-Reply-To: <20220414164801.1051-1-mario.limonciello@amd.com>
A message is emitted to let users know they can enable shared memory,
but it shows on all CPUs.
As this parameter is system-wide not CPU specific, it doesn't make
sense to show 8+ times. Modify it to print only once.
