Subject: [PATCH 07/12] habanalabs: add power information type to POWER_GET packet
Date: Sun, 28 Nov 2021 21:34:30 +0200	[thread overview]
Message-ID: <20211128193435.266534-7-ogabbay@kernel.org> (raw)
In-Reply-To: <20211128193435.266534-1-ogabbay@kernel.org>

From: Tomer Tayar <ttayar@habana.ai>

In new f/w versions, it is required to explicitly indicate the power
information type when querying the F/W for power info.
When getting the current power level it should be set to power_input.
