[PULL 09/10] hw/misc: deprecate the 'sga' device |
Date: |

From: Daniel P. Berrangé <berrange@redhat.com>
This is obsolete since SeaBIOS 1.11.0 introduced native support for
sending messages to the serial console. The new support can be
activated using -machine graphics=off on x86 targets.

+The ``sga`` device loads an option ROM for x86 targets which enables
+SeaBIOS to send messages to the serial console. SeaBIOS 1.11.0 onwards
+contains native support for this feature and thus use of the option
+ROM approach is obsolete. The native SeaBIOS support can be activated
+by using ``-machine graphics=off``.
