[Qemu-devel] [PATCH 4/4] net: convert NetClientState to QOM |
|
Date: |
Thu, 18 Oct 2012 16:56:55 +0200 |
From: Stefan Hajnoczi <address@hidden>
This patch makes all net clients QOM objects. This is the first step to
converting the net subsystem to the QEMU Object Model. At this point
net clients are not yet visible in the QOM tree and there are many
simplifications that can still be made to drop ad-hoc code in favor of
QOM.
The major changes are:
1. NetClientInfo becomes NetClientClass. The "virtual functions" (aka
callbacks) for net clients are defined here and overridden by
NetClient child classes.
2. NetClientState becomes a QOM object.
3. NICState becomes a QOM object with NetClientState as its base class.
In other words, a NIC is-a net client.
All net backends in net/ and NICs in hw/ must be converted to NetClient
subclasses. This makes up the bulk of this patch and was done
automatically using a script. Unfortunately there is no clean way to
split these changes into separate patches.
The net_client_type enum has been dropped. For now users have been
replaced with object_dynamic_cast() to test the type of an object. The
cleaner solution is to design polymorphic interfaces instead of
sprinkling code that tests the specific type of an object throughout the
net subsystem.
Note that extrafx_eth.c uses tabs and checkpatch.pl will complain. The
rest of the hunks are clean.
