Subject: [PATCH 1/1] mmc: Set optimal I/O size when mmc_setip_queue
Date: Fri, 18 Aug 2023 10:28:15 +0800 [thread overview]
Message-ID: <20230818022817.3341-1-Sharp.Xia@mediatek.com> (raw)
From: Sharp Xia <Sharp.Xia@mediatek.com>
MMC does not set readahead and uses the default VM_READAHEAD_PAGES
resulting in slower reading speed.
Use the max_req_size reported by host driver to set the optimal
I/O size to improve performance.
