Dear coreboot folks,
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?
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.
If I am right about Chrome OS, do the developers have any suggestions? Are you content with your interface and can it be generalized for different boot loaders?
Thanks,
Paul
