Subject: [v2 27/30] dma/dpaa: improve silent mode support
Date: Mon, 22 Jul 2024 17:28:40 +0530 [thread overview]
Message-ID: <20240722115843.1830105-28-g.singh@nxp.com> (raw)
In-Reply-To: <20240722115843.1830105-1-g.singh@nxp.com>
From: Jun Yang <jun.yang@nxp.com>
Don't save eq context in silent mode, check HW status only to
identify if queue is full.
