[Qemu-devel] [PATCH 01/18] smbios: Add a function to directly add an entry |
Date: |
Thu, 19 Jul 2012 13:53:16 -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.
