-Subject: [PATCH] drivers: ata: ahci_sunxi: Increased SATA/AHCI DMA TX/RX FIFOs
-
-Increasing the SATA/AHCI DMA TX/RX FIFOs (P0DMACR.TXTS and .RXTS, ie.
-TX_TRANSACTION_SIZE and RX_TRANSACTION_SIZE) from default 0x0 each
-to 0x3 each, gives a write performance boost of 120 MiB/s to 132 MiB/s
-from lame 36 MiB/s to 45 MiB/s previously.
-Read performance is above 200 MiB/s.
-[tested on SSD using dd bs=4K/8K/12K/16K/20K/24K/32K: peak-perf at 12K]
-
-Tested on the SBCs Banana Pi R1 (aka Lamobo R1) and Banana Pi M1 which
-are based on the Allwinner A20 32bit-SoC (ARMv7-a / arm-linux-gnueabihf).
-These devices are RaspberryPi-like small devices.
-
-This problem of slow SATA write-speed with these small devices lasts
-for about 7 years now (beginning with the A10 SoC). Many commentators
-throughout the years wrongly assumed the slow write speed was a
-hardware limitation. This patch finally solves the problem, which
-in fact was just a hard-to-find software problem due to lack of
-SATA/AHCI documentation by the SoC-maker Allwinner Technology.
-
-Lists of the affected sunxi and other boards and SoCs with SATA using
-the ahci_sunxi driver:
-  $ grep -i -e "^&ahci" arch/arm/boot/dts/sun*dts
-  and http://linux-sunxi.org/SATA#Devices_with_SATA_ports
