[Linux-ia64] How do I set variables in efishell?

[Linux-ia64] How do I set variables in efishell?

[Christoph Rohland]

Hi all,

I still do not know how to set variables in efishell to switch the
console to my serial device.

I actually know that I have to set the variables ConIn and ConOut. But
I am prettty confused by any documentation I can find about actually
setting these variables.

Any help appreciated

Has anybody figured this out yet? Specifically, there is a "set" command in
the EFI shell, but the difficulty seems to be figuring out the device path
to actually set the variables to. Then of course this early firmware may end
up ignoring them anyway. Thoughts?

From what I can glean from the docs and my hacking, a set in the shell
sets a shell variable, NOT a root EFI variable. The only way to set the
EFI variables is to do so from a C app usinf the EFI toolkit. This is a
bit unfortunate as it means one can not add/edit menu items from the
shell prompt. Also, typing exit at the prompt puts you into the boot
menu, but AFAIK there is no way of getting back to the shell.

Plus the fact I haven't found a single version of the firmware which
actually saves these variables. So setting them tends to be useless.

It hasn't been too important so I haven't followed up on it with Intel.

Re: [Linux-ia64] How do I set variables in efishell?

Yes? I've saved variables from one reboot to another. I was using a
workstation (bigsur) with 0.29 PAL, but it worked for me.

note also there is a dmpstore command which shows all the variables.
