Kernel Build Help

[cooker]

Hi all;

I have obtained some SSD's to replace the usb-3 backup type hard drive that failed, and have it configured now, but not yet mounted.

What I intend to do is use it as a build location, to basically follow the recipe as laid out above, but using the latest git clone from the rt-linux site as the app it will run if this effort is successfull, demands at minimum a fully pre-emptible real time kernel. There are also land mines in the conversion of the linuxcnc's rpspi.ko to run on the gpio and spi buss of the rock64 as its been built so it refuses to run if not on an rpi-3b. That will be the 2nd non-negotiable requirement, but one stone at a time.

There be land mines in the make oldconfig based on the current stretch kernel, one of ayufans latest releases. And just updated by apt yesterday.

Can anyone advise me as to how best to do this make oldconfig?

Thank you all;

My humble advice: best is not to do it.

I have my rock64 serving as NAS, music server and NextCloud server.  It runs faultlessly 7x24 for months until I do apt-get update/upgrade last time ^^!!  It just crashes.

I am paranoid enough that I poweroff the board and make a dd copy of the sdcard everytime before I run apt-get update/upgrade.  First time I get my paranoid reward.

Put all data including mysql database onto harddisk.  When the system is toooo outdate someday, download the latest ayufan image, reinstall everything you're running, rebuild all setup, ... and enjoy another months of good value board.  It is still the easiest way of living as of today.
