[Qemu-devel] [PATCH 2/4] qxl: split qxl functions in common and pci files |
|
Date: |
Fri, 24 Aug 2012 16:14:35 -0300 |
From: Fabiano Fidêncio <address@hidden>
This commit splits qxl functions into common functions (located in
qxl.c) and pci-specific functions (located in qxl-pci.c).
All prototypes are being kept in qxl.h, as common MACROS and inline
functions. Moreover, this commit is exposing a lot of APIs, don't know
if it's the correct way to do it, but it was the only way that we saw to
do it.
