[Qemu-devel] [PATCH 19/20] smbios: Add a function to directly add an entry |
Date: |
Wed, 29 May 2013 17:08:15 -0500 |
From: Corey Minyard <address@hidden>
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.
