[Xen-devel] [PATCH 0/2] libxl: add PV display device driver interface

[Oleksandr Grytsov <al1img@xxxxxxxxx>]

From: Oleksandr Grytsov <oleksandr_grytsov@xxxxxxxx>

Hi all,

We are working on series of PV drivers (display, sound, input etc.) and 
would like to add their support to libxl and xl. These patches add PV display
device. PV display is based on [1] protocol.

During implementation I see a lot of code duplication. This problem was 
mentioned in [2]. One of the solutions was to implement common parts in IDL
and make them autogenerated. On my side, to minimize the copy/pasting
I've moved common parts into macro functions: LIBXL_DEFINE_DEVICE_COMMIT,
LIBXL_DEFINE_DEVICE_LIST_GET, LIBXL_DEFINE_DEVICE_GETINFO etc.
Existing PV devices implementations can be reworked to use these macros as
well. Any other proposals to avoid the duplications are welcome. 

Thanks.
