version 20220916 with the change proposed by tkaiser

 

Well, I was talking about 3 different issues:

  • switching with ASPM from powersave to default (you chose performance now, no idea what this does wrt consumption, switching from powersave to defailt is 100mW)
  • io_is_busy (that's addressed now though in a redundant way but doesn't matter since only delaying the armbian-hardware-optimization service by a few ms). Both these changes should help with NVMe (and PCIe device) performance in general
  • setting the dmc_governor to performance instead of dmc_ondemand (results in 600mW higher consumption though). This is reponsible for better overall performance since the dmc_ondemand governor often does not ramp up memory clock fast enough. A comparison between clocking LPDDR4 with only 528 MHz vs. the current maximum of 2112 MHz is here: https://browser.geekbench.com/v5/cpu/compare/17009700?baseline=17009078

The latter isn't addressed at all but I posted multiple times how this can be changed from userspace:

echo performance >/sys/class/devfreq/dmc/governor

Does the change help NVMe SSD speed?

@balbes150 did (only) two changes and the io_is_busy tweak will help with every storage device (USB and SATA too). No need for a new image since you can simply edit /usr/lib/armbian/armbian-hardware-optimization. Or overwrite it with the contests of http://ix.io/4aFe

Open source development is fun. Join Armbian Linux development team today!

Version 20220916 contains an error in the installation files, do not use it to install on eMMC (if you start the installation process, then you will have to restore u-boot using a USB-C cable). There will be a new version with the correct files in the near future.
