Subject: [PATCH 15/26] habanalabs/gaudi2: support abrupt device reset event
Date: Thu, 8 Dec 2022 17:13:39 +0200 [thread overview]
Message-ID: <20221208151350.1833823-15-ogabbay@kernel.org> (raw)
In-Reply-To: <20221208151350.1833823-1-ogabbay@kernel.org>
From: Ofir Bitton <obitton@habana.ai>
In certain scenarios, firmware might encounter a fatal event for
which a device reset is required. Hence, a proper notification
is needed for driver to be aware and initiate a reset sequence.
In secured environments the reset will be performed by firmware
without an explicit request from the driver.
