Hi Paul
as LinuxTag approaches and some of the systemd developers are going to be there, I remembered the discussion how systemd only supports exposing performance data on EFI systems [1].
Christian already brought up coreboot/SeaBIOS in that discussion. H. Peter Anvin (Syslinux) also voiced a need for a having that for non-EFI systems.
Christin, are there any news?
The biggest problem is the defined interface between the coreboot and systemd.
Thanks to the CBMEM console, the cbmem utility can read, and the timer work, we have performance data available now. If I am not mistaken, Chrome OS also supports reading these values. So maybe such an interface could be designed during LinuxTag and implemented afterward.
In the next weeks I will find some time for some coreboot work and maybe I will get something up and running.
