Re: [coreboot] Success in booting the kernel in less that 1 second on the x60

[Carl-Daniel Hailfinger]

Hi Charles,

the main talk deadline and lightning talk deadline for FOSDEM are over,
but maybe some of the developer rooms somewhat fit the topic and still
accept the talk? Not sure.

In any case, it would be great to have you there at FOSDEM at our booth
if we get a booth this year.

Regards,
Carl-Daniel

Well, feel free to suggest it. I'd be glad to be a copresenter. I don't
have enought experience with coreboot yet to answer technical questions

BTW: did you get a similar boottime? I'd love some confirmation on my
results, because I'm using some approximation. I can't rely on
systemd-analyze because I'm using luks for root, and the decode time is
added to the kernel boot time.

Problem is, I'm on the other side of the atlantic :-)
