Anyways I am still hoping for a 4.X kernel, which hopefully fixes the sd card performance issue...


There's an sd card performance issue?

I've been using F2FS on mine, but it's been perfect


It looks like. For all cards I have tried read speed drop to under 20 MB/sec after suspend. @see: http://www.mygnu.de/index.php/2018/07/micr...the-gemini-pda/

Ah fair enough, yes I can repro that too via hdparm with the same 64gb orange EVO card, not really noticed it in my real world use though, I guess it'd be more noticeable if random reads were affected

Also wondering... I have built a modular kernel. If someone wants to use, downloads and some instructions can be found here: http://www.mygnu.de/index.php/2018/06/modu...the-gemini-pda/

Hoping this (or a better kernel) can be included in the next TP.

This is very helpful, thanks! I was a bit confused by the installation section, mine doesn't have a linux_boot, I have boot, boot2 and boot3 .. given I have dual-boot Android/Linux, I guessed at boot2 and seem to be correct wink.gif

It looks like partition names have changed with the firmware upgrade / new scatter file generator. Added a sentence clarifying the partition names.

Huge thanks to mithrandir for discovering the CONFIG_RCU changes! I've added them to my kernel and it appears to have literally doubled screen-on battery life!

I was previously getting 20-25% per hour, now around 10%. It's also running cooler under the same usage

No idea how it can have made such a difference, but I'm not complaining!
