Hello Dirk,
I have made only single change - I recompile ATF to
leave CPU in EL2
mode and reflash it.
Yes, this is what I meant with 'modifying firmware' ;)
You are loading Xen with U-Boot running in EL2, then?
With this modification, do all other use cases still work?
E.g. load and
boot U-Boot and native Linux kernel without Xen?
Yes, when Linux is booting from EL2, it will drop to EL1 (see
el2_setup). As Andre mentioned on the previous thread, U-boot is
running
at EL2 on various board (e.g pine64, juno).
Modifying the firmware was the right way to go as there is no
solution
go boot at EL2 from EL1.
Yes, correct, from general point of view :)
My question to Iurii is more focused to this concrete board, if
there everything works fine, too. You know, sometimes the
implementation on a board might have bugs while it should work well
in theory ;)
So I'm just interested if everything works fine for him switching
ATF to exit in EL2, or if additional fixes/patches are needed for
this board.
Looks like all basic functions working normally - I have successfully
load linux & rootfs without any additional patches for linux kernel.
Ok, thanks for this info :)
As you ok with this - I will create Salvator-X board related page on Xen
wiki.
But first of all, I will update yocto layer mentioned by Andrii with
minimal setup, based on the latest Renesas & Xen releases.
This should be helpful for easier out of box board setup.
Ack
Best regards
Dirk
