Subject: [PATCH 03/11] habanalabs: add current PI value to cpu packets
Date: Tue, 14 Dec 2021 17:05:43 +0200 [thread overview]
Message-ID: <20211214150551.1568192-3-ogabbay@kernel.org> (raw)
In-Reply-To: <20211214150551.1568192-1-ogabbay@kernel.org>
From: Ofir Bitton <obitton@habana.ai>
In order to increase cpucp messaging reliability we will add
the current PI value to the descriptor sent to F/W.
F/W will wait for the PI value as an indication of a valid packet.
