Subject: [PATCH 13/16] habanalabs/gaudi: unmask out of bounds SLM access interrupt
Date: Wed, 18 Aug 2021 16:39:19 +0300 [thread overview]
Message-ID: <20210818133922.63637-13-ogabbay@kernel.org> (raw)
In-Reply-To: <20210818133922.63637-1-ogabbay@kernel.org>
From: Tomer Tayar <ttayar@habana.ai>
The out of bounds SLM access TPC interrupt indicates a severe compiler
