Subject: | Re: [Qemu-devel] [PATCH 15/16] smbios: Add a function to directly add an entry |
Date: | Wed, 13 Nov 2013 08:37:10 -0600 |
There was no way to directly add a table entry to the SMBIOS table,
even though the BIOS supports this. So add a function to do this.
This is in preparation for the IPMI handler adding it's SMBIOS table
entry.
