This patch supports packed write command of eMMC4.5 devices. Several writes can be grouped in packed command and all data of the individual commands can be sent in a single transfer on the bus. Large amounts of data in one transfer rather than several data of small size are effective for eMMC write internally. As a result, packed command help write throughput be improved. The following tables show the results of packed write. Type A: test none | packed iozone 25.8 | 31 tiotest 27.6 | 31.2 lmdd 31.2 | 35.4 Type B: test none | packed iozone 44.1 | 51.1 tiotest 47.9 | 52.5 lmdd 51.6 | 59.2 Type C: test none | packed iozone 19.5 | 32 tiotest 19.9 | 34.5 lmdd 22.8 | 40.7 Signed-off-by: Seungwon Jeon <tgih.jun@samsung.com> Reviewed-by: Maya Erez <merez@codeaurora.org> Reviewed-by: Namjae Jeon <linkinjeon@gmail.com> Signed-off-by: Chris Ball <cjb@laptop.org> |
