H A Dmmc-async-req.rst2 MMC Asynchronous Request
11 pre-fetch makes the cache overhead relatively significant. If the DMA
13 transfer, the DMA preparation overhead would not affect the MMC performance.
15 The intention of non-blocking (asynchronous) MMC requests is to minimize the
16 time between when an MMC request ends and another MMC request begins.
18 Using mmc_wait_for_req(), the MMC controller is idle while dma_map_sg and
19 dma_unmap_sg are processing. Using non-blocking MMC requests makes it
21 MMC request.
23 MMC block driver
26 The mmc_blk_issue_rw_rq() in the MMC block driver is made non-blocking.
