Re: [Xen-users] Xen boot time optimization

[Subhasree P V <subhasree.pv@xxxxxxxxxxxxxxxxxxx>]

Thank you for your reply Julien.I have searched for the "earlycon" option in my linux-dom0.but i couldn't see that option in my Kconfig file.my dom0 version is 4.18.0-15-generic.

Thanks & Regards,

Does the same configuration works on baremetal?

Another solution would be to add earlycon=xen on Linux command line (I
think this works on arm32 as well when CONFIG_SERIAL_EARLYCON=y).
