Subject: [PATCH 14/16] habanalabs/gaudi: define DC POWER for secured PMC
Date: Wed, 18 Aug 2021 16:39:20 +0300 [thread overview]
Message-ID: <20210818133922.63637-14-ogabbay@kernel.org> (raw)
In-Reply-To: <20210818133922.63637-1-ogabbay@kernel.org>
In secured mode, the CGM is disabled. Therefore, the DC power is
higher. Without taking it into consideration, the utilization is
12-15% at idle.
Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
