From 75a5c44d143bc1818e8004a8bee6993aba3a75cf Mon Sep 17 00:00:00 2001 From: Tomer Tayar Date: Thu, 18 Nov 2021 10:44:05 +0200 Subject: [PATCH] habanalabs: add power information type to POWER_GET packet 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.
