This backports SATA performance boost from 5.3 kernel:
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]
dd bs Before MB/s After MB/s Increase
4k 14.4 16.5 15%
64k 34.5 74.4 116%
1M 40.5 93.2 130%
