Subject: [PATCH 03/12] habanalabs/gaudi: return EPERM on non hard-reset
Date: Sun, 28 Nov 2021 21:34:26 +0200 [thread overview]
Message-ID: <20211128193435.266534-3-ogabbay@kernel.org> (raw)
In-Reply-To: <20211128193435.266534-1-ogabbay@kernel.org>
GAUDI supports only hard-reset. Therefore, this function should
return an error of operation not permitted.
