Holsteiner Posted December 29, 2015 Share Posted December 29, 2015 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... holsteiner Link to comment Share on other sites More sharing options...
wildcat_paris Posted January 3, 2016 Share Posted January 3, 2016 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. Link to comment Share on other sites More sharing options...
