Hello community,

 

Kernel 4.3.x should have support for DMA engine on A20 boards, see:

http://linux-sunxi.org/Linux_mainlining_effort#Merged_into_4.3

 

Does / should this also improve the SATA write performance?

 

After update to kernel 4.3.3 from apt.armbian.com I cannot see any big write Performance increase...

 

thanks for comments...

 

best regards and a happy new year...

Happy new Year!

 

AFAIK as I am a newbie, the DMA exists for itself. I am unsure if there is/will be any possible glue to improve SATA perf.
