Sunxi, SATA write speed patch

lee_me · February 4, 2020, 2:24pm

Dear developers,
I have been using OpenWrt with Lemaker's Banana Pro. It works wonderful for a router & minidlna server.
Lately I read about kernel patch for Allwinner A20,
link below :

It makes the sata write speed improvement up to 100+ MB/s.
How to make this patch work on OpenWrt ?
Or any plan to include this patch to next openwrt version? Thanks

Hi,
This patch is in mainline linux since 5.3. Next OpenWRT release should have this patch.
It should be easy to backport it to snapshot. Do you have hardware for tests?

I just have one for my daily use.
