Subject: [PATCH 05/10] accel/habanalabs/gaudi2: fix undef opcode reporting
Date: Wed, 15 Nov 2023 18:39:07 +0200	[thread overview]
Message-ID: <20231115163912.1243175-5-ogabbay@kernel.org> (raw)
In-Reply-To: <20231115163912.1243175-1-ogabbay@kernel.org>

From: Dafna Hirschfeld <dhirschfeld@habana.ai>

currently the undefined opcode event bit in set only for lower cp and
only if 'write_enable' is true. It should be set anyway and for all
streams in order to report that event to userspace.
