Subject: [v2 10/30] dma/dpaa2: limit the max descriptor number
Date: Mon, 22 Jul 2024 17:28:23 +0530	[thread overview]
Message-ID: <20240722115843.1830105-11-g.singh@nxp.com> (raw)
In-Reply-To: <20240722115843.1830105-1-g.singh@nxp.com>

From: Jun Yang <jun.yang@nxp.com>

For non-SG format, the index is saved in FD with
DPAA2_QDMA_FD_ATT_TYPE_OFFSET(13) bits width.

The max descriptor number of ring is power of 2, so the
eventual max number is:
((1 << DPAA2_QDMA_FD_ATT_TYPE_OFFSET) / 2)
