I did a simlar setup some time ago for a narrower use case: I needed extremly fast reflashing times. I only had: * A stock parabola(A GNU/Linux distro based on Arch) * Good kernel commandline(to reduce logging) * A well configured grub. * No password at all, even for getty. > - I had to add a sleep 3 before starting the web browser with an > actual site to get the site to load (due to dhcp/wpa_supplicant/etc) You could gain a lot of time by obtimising DHCP [1]. I've no idea about wpa_supplicant though. You could also replace the sleep by something better: you could look if you can get the status of the network connection somehow: * Maybe trough dbus, but using dbus may slow down the startup. * Else simply launch the browser with the right arguments once the network is there. You'll have to find the right arguments for that, so it remains usable if the network comes and go. > I use linux-3.10.45 and systemd-stable v210, and you can see the > result from a systemd-analyze - about 2.8 seconds after > coreboot+grub, which take about 3 seconds.

Hi David, Thanks for that. Perhaps I phrased the question wrongly. I guess what I should've said was I'm not sure if you're still at the uni or gone to some pub. :) Thanks, John.

What ramstage.o did you look at? What did the symbols say for these objects? Are the sizes for the OBJECT types set to 20 for sure (I'd expect it to be)? The following could be related: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61296 We might be playing whack-a-mole and need to align all of our special sections up to a typical cacheline (64) in the linker scripts.
