Re: [Xen-devel] VM SMBIOS struct field manipulation

["C.J. Adams-Collier" <cjcollier@xxxxxxxxx>]

Great.  Thanks Kier,

I'll get familiar with it.  If we create a patch to allow SMBIOS structure updates from a data source via dom0, would you want it?

It looks like using a custom boot_ioremap from linux-2.6.18-xen.hg
/arch/i(386|a64)/kernel/efi.c might allow manipulation of smbios fields for PV guests.  Are you familiar enough with this code to tell me whether I'm entirely off base here?

Cheers,

C.J.

PV guests don't get an SMBIOS table; only HVM guests do. To change the structure (Which is fairly hardcoded) you need to modify the hvmloader sources. Look at tools/firmware/hvmloader/smbios.c.

Hey folks,

Is it possible to define smbios struct fields <http://src.vmindex.org/xen_3.0.4/xref/src/tools/firmware/hvmloader/smbios_types.h#75>  in the xmdomain.cfg <http://src.vmindex.org/xen_3.0.4/xref/src/docs/man/xmdomain.cfg.pod.5>  files?

If not, which files should I patch?  Do I need to create my own "device_model" or "loader" driver?  I would like to do this for both HV and PV.

Cheers,

C.J .
