Re: [Qemu-devel] [ARM SMBIOS V2 PATCH 0/6] SMBIOS Support for ARM

[Leif Lindholm]

Hi Wei,

So, I can verify that this works all the way into Linux userland
dmidecode on arm64.

One question:
This set still leaves the -smbios set of options x86 only.

Would

be relevant to add here (6/6), and would that then be expected to work
for filling in values via command line (because that does not
currently appear to be the case).
