Subject: [PATCH] habanalabs: fix pm manual->auto in GOYA
Date: Sun, 22 Mar 2020 16:39:04 +0200 [thread overview]
Message-ID: <20200322143904.2305-1-oded.gabbay@gmail.com> (raw)
When moving from manual to automatic power management mode in GOYA, the
driver didn't correctly place the device in LOW power mode. As a result, if
an application was run immediately after the move, it would have run with
low frequencies.
